Reduce heating costs by using indirect gain in your home design


Heating costs are quite high these days and are expected to increase only in the future as fossil fuels become scarce. Incorporate indirect gain into your home design and you will save a package.

Indirect gain is a form of heating to solar energy. Now, do not panic. When most people talk about solar energy, the idea of ‚Äč‚Äčlarge and unattractive solar panels immediately comes to mind. Indirect gain does not involve solar panels. Instead, it uses the natural power of the sun to create heat for your home. Yes, even in winter.

The energy of sunlight is obscene. On a clear day, there is enough energy in a square meter of sun to produce 1 kilowatt of power. So, why does not solar energy take off as a renewable energy platform? We can not yet build solar cells that are efficient enough to exploit energy. Most panel solar cells only convert about 10% of the energy of sunlight that strikes them. This is why the panels must be so big to generate enough electricity.

With the indirect gain, you do not have to worry about solar panels or even efficiency. The indirect gain comes from heating a part of a house and then to the heat that flows into the rest of the house. A classic example is a Trombe wall, but in this case we will talk about a sun room.

A sun room is simply a room built on the south wall of your house. The exterior walls and the roof are in glass. The floor and the inner wall are made of a material that absorbs the heat of the sun. The floor can be brick, for example. The wall can be painted in a dark color. It does not really matter as long as the sun is warming up. During the day, the sun will roast your solarium. This is true even in winter if you isolate yourself well. So, how do you get all that hot air in the rest of the house? I'm glad you asked!

To move warm air into the rest of the house, you need to install a simple but unique evacuation system. A set of vents should be placed as high as possible and as low as possible on the interior wall of your solarium. The vents should lead to an interior space of your home with as short a distance as possible. Remember, warm air rises and we will use this fact to our advantage.

When you need heat in the house, you can open the two sets of vents – at the bottom and at the top. The warm air of the sun room will be transferred into the house through the upper vents. At the same time, the fresh air from inside the house will be transferred to the sun room through the lower vents where it will be heated by radiant energy on the floor and the wall inside the sun room. The net effect is that you have used the energy inherent in sunlight to heat your home!

So, what is the effectiveness of indirect gain when it comes to heating your home? It can reduce your costs by about 60%. During the life of your home, this is a good part of the change.
