A geothermal heating pump system can be a great solution for keeping your house warm during the winter months but also cooling it down during the summer. It has a low carbon impact, uses a natural source of heat and can help lower your energy bills.
So if you are still a bit skeptical about whether installing a geothermal heating pump system is worth investing in, here are some advantages that might help you make up your mind!
Geothermal heating pumps save money
By installing a geothermal heating pump you can save money. Getting a geothermal heating pump will cost you around $15,000–$20,000, including installation costs, ground loops, heat pump, and controls .
While this is a substantial upfront investment, most countries provide incentives to make it easier for citizens to install such heating pumps.
For example, in Canada there is a $3,500 federal grant, in the U.K. the government has put in place a “Renewable Heat Incentive” scheme which provides payments between £2,500-4,000 to households opting for heat pumps.
In the United States, there is a standard federal tax credit .
Return on investment
Even without those government incentives, you can see a return on your investment quite swiftly. A study conducted by the Air Force Institute of Technology estimated that it takes 7-8 years to recoup costs .
Similarly, the UK’s Energy Saving Trust calculated that a geothermal heating pump, or a ground source heat pump as it is also known, can help you save between £410 and £2,000 each year, depending on which existing heating system you would be replacing .
If you want to find out how quickly you will be able to make up for your investment, speak to an experienced installer who can conduct a more expert calculation based on your heating system, energy needs, geology and other parameters .
High efficiency of geothermal heat pumps
Geothermal energy heat pumps are also considered a more efficient way to heat your home. Even though you still need to use some electricity to power your ground source heat pump, you get a lot more energy for every of unit of electricity you pay for – specifically you can get up to four unit of heat more compared too other ways of heating . This brings about an up to 70% decrease in your heating and cooling bills .
Efficient cooling of your house
A geothermal pump is also more efficient when it comes to cooling your home too. An air-source heat pump takes the heat from your home and transfers it outside, but when the air is hot outside this becomes more difficult. So at the time when the air-source heat pump needs to perform at its best to cool your house effectively, it is much less efficient.
A geothermal pump however relies on underground temperatures which are cooler compared to ambient air during the summer months .
The geothermal heat pump delivers a more efficient heating and cooling system while eliminating noisy outdoor compressors and fans.
Low greenhouse gas emissions
Lastly, but certainly most importantly, a ground source heat pump emits much less CO2 compared to conventional heating systems. This is because they rely on ground temperatures, require less electricity and are an efficient heating and cooling system .
Hopefully the arguments above have helped you make a decision about whether to get a geothermal heating pump!
