The watchword these days seems to be green everything. The cars are greener; the grass is greener, but only on the other side; and heating systems are greener. What? You haven’t heard of a green heating system? You thought you were stuck with the standard gas or electric options?
If you are thinking about building or remodeling your home, then try a geothermal heating system to keep the costs and your carbon footprint down.
A home-sized geothermal heating system will cost you about twice the regular amount of the gas and electric alternative, but will more than make up for the cost over time. It is a bit construction intensive, though. It starts with a system of pipes that are placed underground below the frost line, where the temperature is constant.
The pipes are connected to a fan in the home that sucks in the air and circulates it through the pipes and then blows back into the home. The key is the temperature in the underground piping. Let’s say the temperature outside is -10 degrees. The air gets sucked into and runs through the underground pipes, where the ambient temperature in the ground warms it to the temperature of the ground about 60 to 65 degrees.
The reverse is true in the summer. If it is 100 degrees out, then the pipes will cool the air to the ambient temperature in the ground. The constantly cool air is circulated though the home. The only cost is the electricity of the fan.
You should always have a smaller backup heating and cooling unit for those days when it is too hot or cold and it needs that extra boost. Geothermal heating systems are becoming popular in new-home construction because they have a much smaller carbon footprint than electric and natural gas furnaces, and are actually healthier in the long run.
The air that circulates is not flash heated in a furnace, so the moisture is not taken out. As someone who suffers from sinus infections easily, I wake up most days during the winter with a sore throat and a congested nose. That wouldn’t happen with a geothermal unit.
You can boost your efficiency by having large windows to capture the sunlight and concrete floors to absorb the heat and cold. Everyone wants to be green, and geothermal is about as green as you can get without living in the wild.
