A furnace has to burn fuel in order to generate heat. Combusting the fuel is the easy part; the real challenge comes when you try to extract heat from the exhaust created when you burn fuel. In that a furnace has to create its own heat, it will never be more than 100% efficient. In other words, the whole point is to get a unit of heat for every unit of fuel you burn. In that a ground-source heat pump simply has to move heat from one place to another, you can achieve greater than 100% efficiency.
How Does a Heat Pump Work?
A heat pump vaporizes freon in one set of coils to absorb heat from the air surrounding the coils. The heat pump uses a compressor to pump the freon to a second set of coils where a fan pushes air over the coils to extract heat from the coils until it condenses back to a liquid. By absorbing heat from outside your home and venting it inside your house, you can heat your home.
Why Go for a Ground-Source Heat Pump?
Heat pumps that are exposed to the outside air are subject to the constantly fluctuating nature of the air. Heat pumps struggle to extract heat from the air when temperatures get down close to freezing. If you live in a cold environment, you might think that a heat pump won't work for you. Instead, you need to consider a ground-source heat pump.
A ground-source heat pump will bury a specially designed coil system under the ground so that you can extract heat from the earth itself. Simply by burying coils ten feet below the earth's surface, you can tap into moderate temperatures—between 50-60˚ year round. This allows your ground-source heat pump to move six units of heat into your home with every unit of electricity that it uses. In other words, a ground-source heat pump can reach up to 600% efficiency.
If you don't want to pay too much to heat your home, then you need to pay careful attention to the type of heating equipment you use. In many cases, a furnace is a good choice. In that it creates its own heat, you don't have to worry about outside temperatures affecting your furnace's ability to heat your home. On the other hand, if you install a ground-source heat pump, you can get highly efficient operation from a heat pump, no matter what the outside temperature is.
