If you’re looking to replace your furnace, now would be a great time to switch to a geothermal heat pump (GHP). Since they utilize a natural source of energy, GHPs are well over 100 percent efficient. In fact, they can reach efficiencies as high as 600 percent. Since heating and cooling usually compromise the majority of a household’s energy use, this can lead to much lower energy bills. It also makes it easier to make your home self-sufficient energy-wise via onsite electricity generation from renewable sources.
Geothermal heat pumps
A few feet below the surface, the ground remains at a nearly constant temperature—around 50 degrees. GHPs utilize this source of constant temperature to heat and cool your home. Some varieties even use it to heat your home’s water. GHPs work the same as air-source heat pumps, except they exchange heat with water that’s circulated through underground pipes instead of the external air. This means they can offer great performance regardless of the temperature outside.
Renewable electricity generation
Even if you don’t replace your furnace with a geothermal heat pump, you may want to look into onsite renewable energy sources as a way to cut down on the amount of electricity you use from the power company. There a few different cost-effective options potentially available:
- Solar energy – Photovoltaic cells generate electrical energy when exposed to sunlight. These are best installed in locations that receive a lot of sunlight. There are many types and installation options.
- Wind energy – The kinetic energy of wind can be converted to electrical energy via a wind turbine. These are mounted on a tower and are best in windy locations.
- Microhydropower – You may want to look into building a microhydropower system if you have a natural flowing water source on your property. These are capable of generating a large amount of electricity.
All the energy generation systems will require equipment to manage the flow of electricity to the grid, appliances or batteries.
