Geothermal heat pumps, which are used primarily for heating, are widely spread in North America, Northern Europe, Switzerland (up to 80% of homes equipped with geothermal heat pumps). This is due to high prices on gas and cheap electricity.

Solar energy which comes to the Earth distributes the next way: 6 percent is reflected by earth, 17 percent is reflected by clouds, 8 percent is vanished in atmosphere, 19 percent is absorbed by steam, dust and so on, 4 percent is absorbed by clouds and 46 percent is taken up by ground.

Geothermal heat pumps use natural heat that persists in inner soil and groundwater. It is used for efficient heating of your home. The principle of a relatively constant temperature for warm and cold seasons at the depth of 1.5 meters is possible for virtually any region of middle latitudes.

Geothermal heat pumps have stable temperature for any season of the year comparing with air pumps, which lose their efficiency, if the temperature is -10 degrees Celsius or lower.

Let’s look through some Pros of geothermal heat pumps usage:

– Cheap heating. It is cheaper than electricity by 70 percent.

– It may heat your home in cold weather and cool it when it’s hot.

– Simple in use, does not require any peculiar maintenance.

– Need some investment, but then it is cheap.

– Can be installed anywhere you live.

– Eco-friendly, produces no emissions to atmosphere.

– Requires low energy consumption.

Design features

Geothermal heat pumps can be installed horizontally or vertically. Both ways have their own features. For instance, there should be dug a ditch where the system is installed. Everything is determined by specialists, because the depth of ditch and length of tubes depend on the chosen capacity of heat pump and some other factors. So, you should only choose a company, which will make all the calculations to select the system individually for your home.

After a heat pump is installed it can be used not only for heating, but for cooling your home as well. It may seem incredible, but cold air also contains some heat. The only thing is that an air pump should spend more work for heating this way. That’s why geothermal heat pumps are more efficient, they take heat from earth. As for cooling, geothermal heat pumps take the heat from your home in hot weather to the ground. So, you may see that this is some kind of cycle used in this system. Anyhow, it is useful in both hot and cold weather.

Nowadays it is rather costly to install this system for your home. It may cost from 10 to 30 thousand dollars depending on your house. But, if you plan to build your home with geothermal heat pumps, you can use their cost as a part of your mortgage loan. Moreover, the US government has various programs for people, who use geothermal energy. So, you may look for grants and tax incentives that you may apply for by using geothermal heat pumps.
