Double-glazing, Windows and External Doors

Double-glazing, Windows and External Doors

Within the home, dealing with the change in seasons usually involves dusting, washing, storage and hauling items out of cupboards every 6 months or so.  Green homes are kept at an even temperature all year round, by means of insulation.

A window or glass door made of 2 separate plates of glass makes up a double-glazing system.  An air cavity traps air between the glass layers – and these air cavities actually insulate the home, keeping us comfortable.

Double-glazing helps retain warm air during winter and cold air during summer – this helps save money in the long run.

Through a combination of insulation materials and techniques, a well-insulated home means that utility costs are reduced by more than half.  Heating the home in winter and cooling it in summer won’t cost nearly as much.

What makes a green home green?

What makes a green home green?

Today, many developers use the term ‘green’ to describe their buildings. But what are the elements that really make a house environmentally friendly? Does it only refer to using solar power for heating your water? Or harvesting rainwater in a cleverly hidden tank? Seeing as the term gets thrown around so often, we decided to give you a better understanding of what makes a home green.

If you’re serious about green living, there are six general aspects you should consider when building or buying a home. Each of these aspects possesses other smaller elements that are optional. In the end, you will need to decide which ones you can afford, and which ones you don’t really need. Here are the six we have highlighted—with a brief description of each.

Generating energy

Photo-voltaic solar panels are the obvious answer to reducing your reliance on the grid. But you should consider your needs carefully. How much energy would you need, to generate power for all of your appliances? Be realistic and look at ways to reduce the amount of energy you require. Ask yourself whether it’s worth investing in energy efficient appliances. Finally, work with a developer that understands how to utilise orientation, shading devices and insulation to lower your requirements.

  • How much energy will you need?

Measuring the amount of energy you need is step one. Step two is working out how much renewable energy you need to generate in order to maintain your household. It’s simple math and the answers are out there. Remember to do these sums thoroughly before you add this feature to your home—or purchase a home that has it already implemented.

  • Should you also buy energy efficient appliances?

Appliances that are designed to use less power can be extremely helpful too. However, this is not an option for everybody. If you have to balance your comfort and convenience, then these appliances are not going to make your life better. Living cheaply, doesn’t mean you have to live less comfortably. Rather generate lots of free, renewable power than having to lower your lifestyle.

  • Should you work with a green home developer?

Green home developers have already worked with green vendors. They’ve had their bad experiences with the dubious ones and finally found teams of individuals who deliver what they promise. That’s why it can be beneficial to work with these developers for advice. If you are looking for someone to help you get it right the first time, speak to someone who’s already made all the mistakes and come out on top.

Harvesting rainwater

After energy, a sustainable water supply is essential for any green home. Every effort must be made to make the collection of rainwater as efficient as possible. This requires expertise in the placement of pipes and catchments. Once again, developers need to have local knowledge of the rainfall patterns in your area to ensure maximum collection.

The most efficient rainwater harvesting methods are the cheapest. Finding a way to collect as much water as possible is the trick to maximising your efficiency and your savings. Remember, the more water you collect, the more you will benefit from your return on investment.

Once again, it’s important to use a proper expert to do this implementation in your home. Working with a green home developer who knows a good vendor, or finding a vendor with an excellent reputation is the key to getting the best system.

There are many important aspects to this green feature:

  • Positioning of the catchments
  • Installation of the pipes
  • Choosing the right collection point
  • Having high quality equipment all round

Only true experts will give full attention to detail with ALL of these aspects. So be sure to speak to the right people about installing your rainwater harvesting system.

Choosing materials

A home that is truly green is one that takes every part of the building process into consideration. And that includes the materials that are used in its construction. Bamboo is an example of a sustainable alternative to wood. It has a much lower impact on the environment but is just as durable.  It can be used for flooring, counter tops and in the construction of shaft covers.

Having a truly green home means using materials that have little impact on the environment. We’ll use bamboo as an example here. There are three questions to ask when choosing material:

  • Does harvesting this material take a lot of energy?

In the case of bamboo, harvesting has a significantly lower impact on the environment than other methods. These include cutting down large trees, mining, farming, etc.

  • Will the removal of this resource from nature negatively affect the planet?

Unlike trees, bamboo does not play that much of an important role in dissipating greenhouse gasses. Bamboo isn’t a huge oxygen producer either, so removing it has a very low impact on our planet.

  • Does this resource grow or generate fast enough to sustain its demand?

Bamboo grows incredibly fast! If and when the demand for bamboo increases, growing more will be quick and simple. This makes it incredibly sustainable as a building material.

Insulating the rooms

Being green is not only about harvesting natural resources for living. It’s also about maintaining what you have without needing to continually generate more. This is especially true in the case of heating and cooling your home. That’s where insulation comes in.

There are many ways you can insulate a room. For now, let’s just look at five:

  • Ceiling insulation

By insulating your home’s ceiling, you ensure that warm air cannot escape. Even though your ceiling is solid, air escapes through it much easier than you realise. This is an especially useful feature during winter. Warming up a room takes time, and that heat will not leave the room so easily.

  • Floor insulation

Floor insulation is another way to keep the temperature in your home constant. But more importantly, floor insulation ensures that your under-floor heating or cooling system (hydronics radiant heating and cooling system) retains its effectiveness.

  • Wall insulation

Probably the most effective way to retain a home’s desired temperature is through wall insulation. This is often done by using products such as Lambdaboard within a cavity in each exterior wall.

  • Window & glass door insulation

So much air escapes through closed doors and windows. In the case of windows and glass doors, even sealing the sides will not prevent air from escaping through the glass itself! Double glazing offers the solution here. By trapping the air within a small cavity in the window pane, your rooms will retain the temperature you set for them.

  • Pipe insulation

A homeowner who has truly adopted a green lifestyle will always insist on pipe insulation. This has a number of benefits:

  • Less electricity is needed to reheat water that would otherwise have cooled down faster
  • Water within pipes retains its heat so that water is ultimately saved by not having to run the tap for long
  • Pipe insulation also prevents your cold water pipes from reaching room temperature too quickly. This again saves you on having to run the tap longer when the water is required.

Consider your garden

Gardens take up a lot of time and effort to maintain. Even if you exclude the watering of a garden, there’s still the pruning, treating and mowing that goes into that maintenance. All of these things have an impact on the environment. So what’s the secret to owning a garden that’s as green as your home?

One of the biggest suggestions we put forth to our clients is the importance of planning indigenous trees and plants in a garden. Why do we see this as a green aspect? Because:

  • Indigenous plants need very little maintenance
  • They attract natural wildlife and birds to your garden
  • These plants require very little watering
  • They grow well together
  • They stay green all year round—that means less replacement gardening for you

Learning about invasive plant species in South Africa is also something you can do to be a more responsible homeowner. There is tons of information on the Internet about this subject. Fortunately for the South African environment, this topic is getting a lot of attention at the moment.

As you can see, gardening is a major part of living green. If your garden isn’t green, time to get a revamp. Green, environmentally friendly gardens are an essential part to reducing your carbon footprint.

Thinking about the little things

Another truly green aspect of any home is how easy it is to maintain the little things. We’re talking about cleaning, repairing, treating, painting, polishing… all those things that require time, energy, and chemicals.

Living green means thinking ahead about small aspects of maintenance. Today there are countless options available to homeowners and developers. Let’s take a brief look at some of them:

  • Low maintenance roof tiles

You can now purchase uncoloured roof tiles. This means that you will never have to paint them. It also means that they will never fade from the sun or rainfall. There are no side effects either. These tiles are durable, aesthetically pleasing and cost effective.

  • Stainless steel fittings

Something else to consider is that stainless steel is a great option for certain metal fittings within your home. Stainless steel is easy to clean. It’s also rust resistant and doesn’t require chemical treatment to maintain it.

  • Less lawn area

Maintaining a large area of lawn can be very expensive. It also takes up loads of energy and machine power to do so. If you want to truly live as green as possible, why not consider replacing lawn space with garden decor? This can include pretty rocks & pebbles, pavers, stepping stones, ground cover plants, gravel areas.

Retrofitting existing homes with these features can be challenging. But green homes are becoming more popular in South Africa. Purchasing a brand new green home is already an option that is available to those who appreciate the benefits of green living.

Sleep better in a green home

Sleep better in a green home

It’s one of the benefits of eco-friendly houses that few people are aware of. And while getting a good night’s sleep may not be the most obvious reason you should invest in a green home, it does have its advantages. When you’re well rested you perform better and that leads to an overall improvement in your quality of life.

But how do eco-friendly homes promote better sleep? The two important factors that influence sleep are noise pollution and air pollution. Green living promotes cleaner air and a quieter environment. Let’s look at how this can be achieved.

Perfectly insulated

Insulation plays an important role in maintaining a comfortable temperature without consuming electricity. Such as:

Double-Glazed Windows:

Double-glazed windows are made up of two pieces of glass with a gap between them. The windows are tightly fitted to the frame to eliminate the possibility of air leaks. Not only does this prevent cold outside air from sneaking in through gaps, it also stops warm inside air from leaking out. It makes it much easier to control the temperature of the room which in turn keeps your room at a comfortable temperature for sleeping.

But the double-glazed windows also dampen the sound and keep the room quiet and peaceful. You’ll be able to drift off to sleep without flinching at every sound you hear.

Insulated walls

This is another green living feature that has a dual purpose. First and foremost, it is best to use an eco-friendly insulating material called Lambdaboard. This material is completely recyclable which makes it ideal for use in eco-friendly houses. Lambdaboard is also highly resistant to chemicals used in adhesives during the building process. This makes it sturdy and durable and unlikely to sustain any damage.

Wall insulation not only helps eco-friendly houses to retain warmth in winter, it also provides sound insulation. Blocking out the noise of traffic and making your home a haven of peace and quiet.

Ceiling insulation

It’s not uncommon for traditional houses to have some form of insulation in the roof. But this is often composed of harmful asbestos fibres which can be a health hazard. Once again, it is always best to employ an eco-friendly alternative.

Isotherm is a material made from recycled bottles, which means it’s sustainable and reduces your home’s carbon footprint. But it’s the addition of another insulating material that serves to protect your home from all forms of noise.

If you’ve never experienced a home that’s so well insulated it can be difficult to imagine how this could make a difference to your sleep. But light sleepers will appreciate the reduction in noise levels as a result of the thorough insulation offered by a greener living.

At the same time, all this insulation allows the kind of temperature control that ordinary home owners can only dream of. Eco-friendly homes remain warm in winter and cool in summer without needing to depend on heaters and air conditioners. If you do need to warm up or cool down a room this is achieved with the Hydronics Radiant heating and cooling system. A system of pipes laid under the floor that enables pumping hot or cold water to areas in the home where needed. The system is operated with little electricity and the temperature of each room can be adjusted independently.

It’s worth noting that the floors should also be insulated. The main reason for this is to make the Hydronics Radiant heating and cooling system as effective as possible. Once again it adds to the low levels of noise pollution experienced in a green home.

It’s this even temperature that also contributes to getting a good night’s sleep. You won’t have to worry about electric blankets and heaters in the winter or running a noisy air conditioner all night in the summer. You can walk barefoot on your tiled floors all year round without any discomfort. And when you wake up refreshed in the morning you’ll have the energy you need to get through the day with ease.

Pure, clean air

Greener living implies that every element of a home, from the foundation to the roof tiles, is chosen with care. Eco-friendly houses aren’t just good for the environment, they’re better for the people who live in them. Green living extends to the way you decorate and clean your home.

You may not be aware of this, but furnishings such as carpets and wooden furniture are manufactured and preserved using harmful chemicals. That new-carpet smell is merely a sign that your carpets are leaking dangerous VOCs into the air you breathe. Volatile Organic Compounds (VOCs) include highly toxic chemicals such as formaldehyde and benzene. Breathing in these chemicals can result in headaches, nausea and nerve problems.

Over time, these chemicals accumulate in your home, and older carpets are likely to leach even more of these toxic products into your air. On the other hand, eco-friendly houses and buildings use organic materials that aren’t treated with these poisonous products. Bamboo is an ideal material as it’s sustainable, non-toxic and durable. It adds to the clean and contemporary style of the home. Living green doesn’t have to mean unattractive! Bamboo is an excellent alternative to traditional carpeting. And if you would like to add carpets to your home, look for natural materials such as wool.

Paint and wood varnish are also prime sources of VOCs. There are eco-friendly alternatives available. If you’re re-decorating, do some research before you buy a product and make sure it doesn’t contain toxic chemicals that could damage the health of your family. Or consider natural alternatives that don’t require chemicals in the manufacturing process. Sometimes these aren’t readily available or practical, but minimising your exposure to toxic chemicals will help you save in the long run. A healthy home means fewer visits to the doctor.

Chemicals in the home

If living green is important to you, you’ll want to take a closer look at the products you use to keep your home clean. There are many non-toxic cleaners you can use to keep your home fresh and clean. And the good news is that they’re often much cheaper. Baking soda, vinegar and lemon juice can clean just as well as your regular brands, just without the dangerous side-effects. Get creative and make up your own cleaning solutions. Greener living can be a lot of fun and easier on your pocket!

Here are some other things you can do to make sure the air in your home is free of toxins:

  • Vacuum your floors regularly with a HEPA filter vacuum cleaner. These filters trap even the smallest particles and keep them from circulating in the air you breathe.
  • Add a few plants to your home. Plants are good at filtering the air keeping it clean and pure. Do some research to find out which plants are particularly suited to this task.
  • Open your windows. For just a few minutes every day, you should open the windows in your home to allow the air to circulate. Stale air will be forced out and replaced with fresh, clean air.
  • Take your shoes off at the door. Avoid dragging in dirt and toxic particles by removing your shoes as soon as you enter your home.
  • Avoid storing paint and adhesives in your home or garage. Rather, keep these in an area with good ventilation to avoid the build-up of toxic airborne particles.

When you think of a green home you may only focus on the features that help you to save resources and money. Additionally, true green living requires you to go beyond that and examine every element in your home. Your furnishings can contribute to a negative impact on the environment in ways you may not be aware of. By understanding how items are produced you’ll realise just how many dangerous chemicals are involved.

Reducing these toxins in your home is not just kinder to the environment; it also makes your home a safer and healthier space. Whether you have a young family or about to retire, ensuring the air quality of your home is essential for a healthy and happy life.

The importance of good ventilation

There’s another reason why eco-friendly houses result in a better air quality—they’re properly ventilated. Ironically, it’s the insulation that has a big role to play in a properly ventilated home. By preventing air from flowing in and out of your home through gaps in windows and under doors, the air inside is less likely to become polluted from outside sources.

But, when it comes to bathrooms and kitchens, good ventilation can prevent mould and mildew from accumulating. Mould spores are always circulating in the air, but when they find an area with the right combination of damp and warmth, they multiply. That’s why bathrooms and kitchens are most at risk. You may not be aware of a mould problem until it gets too big to ignore. By then, the damage is already done and removing it can be costly.

In eco-friendly homes, good ventilation stops this from becoming a problem. And allergies are less likely to occur when green living principles are applied. Ensuring the purity of the air inside your home is an advantage of green living that few people appreciate. And it makes a real difference to your quality of life.

Sleep easy

Studies have concluded that ‘sick-building syndrome’ does exist. It’s the reason behind poor productivity and an increase in opportunistic infections in the people who live and work in them every day. Eco-friendly houses and buildings promote better health, and it’s been proven. If that’s not enough to convince you to start living green, consider the effects a toxic home has on your quality of sleep.

Clean air and little noise are the best ways to get the rest your body needs. Eco-friendly homes provide these features for homeowners and the benefits are immediate. Families who live in a green home are healthier, happier and more productive. That all starts with a good night’s sleep and the best way to get that is to make sure your environment is clean and quiet.

Another benefit of greener living is the peace of mind it provides for eco-conscious homeowners. When you know that your home and way of life are not impacting the environment to its detriment, you can sleep easy at night.

How double-glazing adds value to a home

How double-glazing adds value to a home

Is there really a need for double-glazed windows and doors in South African homes? Our weather can hardly be compared to that of colder climates where this is an essential feature. And yet, there are more benefits to installing this type of window and door in our homes than we might realise.

Such windows and doors are a popular feature on green homes. That’s because they contribute to the overall energy efficiency of a home. And with the rising cost of electricity, more home buyers are looking for features that reduce heating and cooling bills. Whether looking to buy a new home or thinking about retrofitting an existing home, here’s what we need to know about double-glazing.

What are double-glazed windows and doors?

It is simply a window or door made up of two layers of glass with a gap between them. This gap is usually filled with air, although in some cases it may be filled with Argon or Xenon gas. The two panes of glass are separated with an aluminium spacer and the unit is sealed with silicon. A secondary coating of silicon or bitumen is applied to ensure the glass is completely waterproof.

The air trapped between the two panes of glass acts as a layer of insulation. This makes it more difficult for the cold air outside to pass through the glass and into the home, and vice versa with warm air. This is what makes double-glazed windows and doors more energy efficient.

How energy efficient is double-glazed windows and doors?

Single-pane glass accounts for as much as 40% of the energy lost in a home. Double-glazed windows and doors reduce this figure by as much as 50%. In the winter, double-glazed windows and doors reduce and regulate thermal loss from the inside. While in the summer they prevent solar heat from entering our home from the outside. That means our home will be warmer in winter and cooler in summer.

The use of dehydrated air to fill the cavity between the two panes of glass is what makes these windows and doors so effective at retaining warmth. Heat is normally lost as warm air molecules move from the inside of a window pane to the outside, where it’s colder. Because the molecules of dehydrated air are less mobile than normal air molecules, the heat loss is a much slower process, the same, though in reverse, with cool air in the summer.

What are the other benefits of double-glazed windows and doors?

Not only do double-glazed windows and doors help save energy and cut down on heating and cooling bills—they have many other benefits worth mentioning such as:

  • Reducing noise pollution: Double-glazing helps reduce the amount of noise that may enter our home from outside. This makes them ideal for homes located next to busy roads or even in windy areas.  They also help soundproof our home from the inside out.
  • Draught proofing: Double-glazed windows and doors are well-sealed and fitted which means that little air gets through. Even in areas with high wind, the all-round rubber seal stops any icy draughts from finding their way into the home.
  • Reduced condensation: Because heat is reflected back into the room, and the inside pane is warmer, there’s less chance of condensation forming on double-glazed windows and doors. This means there’s less chance of mold and mildew developing in the bathroom or kitchen.
  • Added security: Two panes of glass are much harder to break so double-glazed windows and doors act as deterrent to intruders. It’s not only the thickness of the window; it’s also the composition that makes it difficult to smash this type of window and door.

Double-glazed windows and doors let in just as much light as regular glass, with added benefits. Why would we want regular glass when we could have something that functions just the same, though makes our home safe, quieter and retains the interior temperature; warmth in winter and cooler in summer?

What to be aware of when installing double-glazing

There are a few things to bear in mind when considering double-glazing. While many green homes include them as a standard feature, retrofitting them requires some consideration. This is what to look out for:

  • The right kind of window and door frame: Bear in mind that frames affect the insulation properties of double-glazing by up to 30%. It’s worth spending the money for high quality frames. Timber frames are a popular choice for their aesthetics. Timber requires some maintenance, and especially when double-glazing is fitted.However, aluminium frames require little maintenance. With these frames we need to consider the thermal break. This is a plastic or resin section in the centre of the aluminium joinery made from an insulating material such as uPVC or wood. This type of frame is less likely to attract condensation and will lose less heat than a standard aluminium frame.
  • Low-emissivity (low-E) glass: It’s worth ensuring that the double-glazed windows and doors use this kind of glass because it cuts heat or cooling loss by about 10% more than those with regular glass.
  • Multiple layers that are well sealed: It is essential that the double-glazing is perfectly sealed. This way they will keep out draughts, moisture and noise effectively. Also ensure that the joint between the frame and the window is well sealed.
  • Spacers made from plastic or stainless steel: This refers to the spacers used to separate the two panes of glass in the window or door. When made from plastic or stainless steel (as opposed to aluminium) they aid in reducing heat or cooling loss and condensation at the glass edge.
  • Inert gas for the filling: Gases such as Argon or Xenon make better insulators. When used for the gap between two glass panes in a double-glazed window and door they reduce heat and cooling loss by an extra 3%. It may not seem like much but when it adds to saving energy—every little bit counts.

How much does double-glazing cost?

Double-glazed windows and doors are considerably more expensive than regular, single-paned glass. The final cost depends entirely on the requirements. How many windows and doors are required? What are the sizes? These are factors influencing the price when looking at the cost of double-glazing.

Why double-glazing works best in conjunction with other insulation methods

On their own double-glazed windows and doors go a long way to reducing the overall energy consumption. The expense of fitting double-glazing to an existing home would not be as effective if done in isolation. It needs to be considered in conjunction with the other insulation, like insulating exterior walls, floors and ceilings. Comprehensive insulation might not be practical or cost-effective. These points need to be considered as a whole.

In green homes they form part of the methods used to keep energy costs low. This is one part of comprehensive insulation to reduce electricity usage, whether drawn from the grid or from photo-voltaic solar panels. In green homes, they complement the floor, ceiling, water pipe and wall insulation. And when combined with the Hydronics Radiant heating and cooling system, the result is a home with a perfectly maintained indoor temperature throughout the year. The savings on [the water and] energy bills in a green smart home are momentous thanks to this holistic approach.

But when retrofitting an existing home there are some possibilities to improve insulation along with fitting double-glazing. For example:

  • Check for draughts and seal them up: It’s a simple matter of looking around the home and making a note of the areas where air leaks in or out. Around windows and under doors is a good place to start. Use sealing strips and caulk to seal any gaps.The idea is to stop warm air from escaping and cold air from entering, and vice versa, so best is to scrutinise every frame, window and door. Even sealing up these little gaps helps to make a home comfortable in summer and winter.
  • Insulating the ceiling: lots of heat escapes through the roof so it’s worth adding insulation to this vulnerable area. There are many different kinds of insulating materials to choose from. However, opt for a green alternative rather than the traditional fibre-glass or paper options. Not only is it kinder to the environment, it’s also healthier for the whole family.One such material, Isotherm ticks all the boxes. It’s made from recycled plastic bottles and can be recycled again itself. It is dust and water resistant, non-flammable, non-toxic and lasts longer than many other insulators.
  • Use thicker curtaining: We usually switch out the light summer duvet for something thicker and warmer in winter, and the same applies to glass windows and doors. Thick curtains will add an extra layer of protection from the cold and stop draughts from getting into the homeUsing this option for windows and doors contains the costs of adding double-glazing everywhere. That way a home is better insulated and the double-glazing installed is effective.
  • Close internal doors: When not using a room, rather keep the door closed. Limiting the airflow within a home goes a long way in keeping the heat and/or cold in and cuts down on electricity usage. Keep in mind that when a room is not in use, it is advisable to balance the electricity spending with maintaining the temperature.Bathrooms are particularly chilly in the winter because they’re filled with tiles that don’t retain heat very well. Keeping the bathroom door closed in winter stops the cold air from seeping out and affecting all heating efforts, and vice versa in summer.

Keeping in mind, when deciding whether it’s worth investing in double-glazing, due to the cost, considering the saving such an investment brings about to heat or cool down our home, and that over the course of their lifespan they pay for themselves many times over. And when implementing comprehensive insulation, further savings are achieved, which recoups the initial investment faster.

A further point is the different experience in summer when the home becomes a cool and quiet haven, or when in winter it is a warm and quiet haven. Not many renovations reduce electricity costs while providing the benefits that double-glazing does. They’ll also add to the value of our property when selling it on. Well worth the extra expense, double-glazing is an excellent investment.

Green Homes Hydronics Radiant heating and cooling

Green Homes Hydronics Radiant heating and cooling

Another winter has passed and it’s time to pack away the heaters and electric blankets. For next year’s winter, during this summer, let’s investigate living the green smart home way to keep our home warm and comfortable next winter. And, cool next summer. And the same for future winters and summers. Hydronics Radiant heating and cooling is a cost-effective way to manage our homes at a comfortable temperature all year round.

What is Hydronics Radiant heating and cooling?

Hydronics Radiant heating and cooling works by circulating warm or cold water through a network of pipes laid in the floor. The system is popular in eco-friendly homes. The heat or cold spreads gently throughout the house and eliminates the need for heaters in winter and air-conditioners in summer. It’s a closed system, thus the water is re-used.

The hot and cold water is ideally obtained from a heat pump which is able to produce water at the required temperature, hot and cold water simultaneously, during the year.

Why choose Hydronics Radiant heating and cooling?

Hydronics Radiant heating and cooling is a cost effective method for heating and cooling our homes. When we’re ready to adopt green living, and combine a Hydronics Radiant heating and cooling system with a heat pump and photovoltaic solar power, the cost savings are momentous.

This method allows for an even distribution of the required temperature, making it more effective than heaters and air-condition. As the warm or cold air rises from the floor it spreads the temperature throughout, keeping it comfortable.

Imagine waking up on chilly winter mornings, putting our bare feet directly onto a tiled floor. Without Hydronis Radiant heating we’d immediately remove our feet and slide them back under the covers. Instead, we’d get up right away and walk on the tiled floors feeling their warmth. People are surprised to discover that living green makes our lives simpler, comfortable and reducing monthly running costs.

What are the advantages of the Hydronics Radiant system?

When compared with conventional heating and cooling methods, the Hydronics Radiant heating and cooling system offers a number of benefits to homeowners:

  • Quiet and comfortable

As mentioned above, Hydronics Radiant heating and cooling distributes heating and cooling evenly throughout the space. We don’t have to limit ourselves to a warm area during the cold months. We work, play and relax in any room without first switching on a heater to warm up the area. Greener living is about comfort at reduced running costs.

Unlike heaters, the Hydronics Radiant heating and cooling doesn’t dry out the air. In certain parts of the country, winter is a dry season. The dry air takes a toll on our skin, hair and mucous membranes. Relying on a heater to keep warm only dries out the air more which impacts on us. Instead, Hydronics Radiant heating and cooling retains the moisture levels present in the air which means our health isn’t impacted.

Finally, a Hydronics Radiant heating and cooling system is clean and quiet. The pipes are laid under the floor and no need to pack away or drag out the appliances as the seasons change. The system doesn’t blow hot or cold air around so there’s no noise at all. We merely snuggle up on the couch in winter and listen to music or watch television without having to turn the sound up. Same in summer, no sound to contend with, just enjoy the comfort.

  • Energy efficient and environmentally friendly

Hydronics Radiant heating and cooling saves us between 60% to 95% on our monthly electricity costs. Think about the electricy we use to heat or cool our homes. Living in this comfort while reducing this cost multiple times is what the ideal Hydronics system enables throughout the year.

When combining Hydronics with the heat pump and photovoltaic solar power, we live in comfort while saving 95% electricity.

At the same time while we’re saving resources, we’re reducing our carbon footprint. Eco-friendly homes are about using resources wisely and efficiently, and living in comfort – and it’s not a passing fad. It’s a win-win for home owners, the environment and the planet – we’re reducing the increasing costs and the strain on resources.

  • Clean, safe and easy to maintain

Floors that are warm and dry inhibit the growth of mold and house mites. And think of how our heaters gather dust in the winter. As soon as we turn them on, they blow dust and other pathogens into the air we breathe. Studies have proven that eco-friendly homes are cleaner and healthier and have better air quality than traditional homes.

A Hydronics Radiant heating and cooling system improves the air quality in our home and our health. When we suffer from allergies or asthma, Hydronics Radiant heating and cooling helps us manage our symptoms and cut down on visits to the doctor.

There’s no risk of tripping over a heater or fan either which makes an Hydronics Radiant heating and cooling system ideal for families with small children or elderly parents.

Hydronics Radiant heating and cooling systems have few moving and mechanical parts and require periodical and minor servicing or maintenance.

We adjust the temperature for individual zones easy via a smartphone app or computer.

  • Flexible design

Because the Hydronics system is laid under the floor, there are no air ducts to consider when designing the home. The pipes are enclosed within a screed, thus out of sight. They cannot be tampered with and provide a secure heating and cooling solution.

The whole floor is used to radiate heat and cold water in the pipes and need to be heated or cooled to a temperature of between 21° to 23° depending on the season. Green living is as cost-effective as it resource-effective.

Whilst most eco-friendly houses include a Hydronic Radiant heating and cooling system as part of their design, this type of system cannot be economically retrofitted to existing houses. It would require that the floor be removed from the finishes all the way to the foundation slab (unless wooden structure and floor.) To accommodate the Hydronics system, the system takes up 15cm containing a vapour barrier, floor insulation, varioprofile water pipes, the screed and tiled floor finish – and a few other intricate modifications.

Instead, when in the market for a new home, look for an eco-friendly home that has the features and advantages of green living. While eco-friendly homes are more expensive, we reap the benefits from when we move in. and years down the road when the time comes to sell the property on.

A word about insulation

Whether keen to invest in an eco-friendly home with a Hydronic Radiant heating and cooling system, be aware of the importance of comprehensive insulation. Without floor-, ceiling-, exterior wall-, double glazing and water pipe insulation, a Hydronics Radiant heating and cooling system will not be as efficient.

Purpose built eco-friendly houses are designed to include insulation at every stage of the building project. It is worth asking the developer about the methods used to ensure that they are efficient and in keeping with green living principles. Wherever possible, insulation would be made from recycled or recyclable material. This is especially important for ceiling insulation; there are various products on the market that cater for this.

Most existing homes aren’t insulated. That’s why we need to do an audit of our home insulation before we retrofit a Hydronics system. Poor insulation adds to the viability of whether to retrofit Hydronics. Though not impossible, it’ll be pricey. And moving out of the residence and placing all furniture in storage during the retrofitting are further costs.

Here are some tips for insulating a home:

  • Check for air leaks: Window and door frames are the most obvious areas where drafts slip through. Ensure all windows and doors close tightly and if they don’t, use weather strips and caulk to seal up any gaps. Just taking care of these small air leaks will make a difference to the temperature of our homes in winter and summer.
  • Insulated floors: With a Hydronics Radiant heating and cooling system, the pipes are on top of the floor insulation and covered by an extra thick screed. A vapour barrier is below the insulation, keeping moist out. The insulation is part of enclosing the space, the screed is a good conductor of the radiant temperature to maximize the system’s efficiency all your round.
  • Ceiling insulation: The insulation is essential to prevent heat from escaping during the winter and the cold during summer.
  • Double-glazing: Investing in double-glazing adds to insulating the space
  • Water pipes: Insulating the regular hot and cold water pipes throughout the home completes the insulation.

When combining a comprehensively insulated home with a Hydronics system, they complement each other and provide a comfortable home while significantly reducing power usage.

Dreaming of living in a home that doesn’t need heaters in winter or air-conditioners in summer? The answer is a Hydronics Radiant heating and cooling system. With such a home an even temperature is achieved all year round and we’re able to manage the temperature in individual rooms. Greener living makes a lot of sense. If in the market to buy a new home, or looking for ways to add real value to our home, consider investing in a Hydronics Radiant heating and cooling system. And start reaping rewards immediately; with big savings on the monthly energy bill and as a sound investment.
