The term “renewable heating” refers to any type of heating system that uses a source that has the ability to renew itself.
This opposes sources such as fossil fuels, which are still in large quantities but are ultimately limited.
The sun is the most popular and widely used source of renewable energy for heating. Solar energy has been around for years, but the relatively new advances in the design and manufacture of solar cells have made them cheaper to manufacture and more efficient to use. The heat produced by solar energy can be used not only to heat homes and businesses, but it can also provide the electrical energy needed to heat the water used in these buildings and provide air conditioning when the temperature is high. This power source is not only practically unlimited, but it does not create pollution.
Another heat source that is actually replaced when in use is geothermal. This method uses ground-source heat pumps to transfer the thermal energy present in the ground to the home or work in cold weather and to extract heat in hot weather. The ground source heat pump can be installed almost anywhere. This type of heating is rated for being energy efficient, quiet and clean.
The relevant heating type is the direct exchange system or “DX”. It is also geothermal, but uses copper tubes filled with coolant to exchange heat with the soil. This system is so efficient that it requires less pipes to be installed than the standard geothermal system and is therefore cheaper to install.
Wind energy can also be used as a heating source. Modern wind generators have grown to be more efficient than they were around thirty years ago. However, large “fields” of these generators are still needed to produce enough electrical energy for wide use, and there are still many people who oppose the visual impact of this on the scene. Also, many places have problems with inconsistent winds or insufficient winds. Despite these problems, there are many coastal and mountainous regions where the winds are fairly constant, and the acceptance of this completely free source of renewable energy still allows for its widespread use.
