Benefits of Geothermal HVAC Systems

If you’re looking for an HVAC system that makes use of the earth’s energy for cooling or heating your space then investing in a geothermal system is a great idea. These HVAC machines operate by cooling and heating your house using the fairly constant temperature under the surface of the earth. When properly equipped, these systems can also supply the house with hot water for free.

Do not confuse geothermal HVAC systems with geothermal power plants. The latter generates electricity by using the earth’s core. However, a geothermal heating system uses the earth’s crust to cool and heat a home; there is no electricity generation involved.

How do they work?

Operation during winters: The pipes underground, also known as the ground loop, circulate water which in turn absorbs the natural heat of the earth and brings it to the heat pump installed indoors. This heat pump excerpts the heat from the water and distributes it within the house as warm air. Once the water’s heat is removed, the same water is re-circulated for collecting more heat.

Operation during summers: Indoor heat pumps suck the hot air from the house to get rid of the heat. This in turn leaves cool air behind to be dispersed through the vents. The heat that is removed from the house is released into the earth with the help of the ground loop. The ecologists acknowledge and regard geothermal systems as the most environmentally clean, energy efficient, and cost-effective systems available in the market.

Here are a few benefits that make these systems so lucrative to homeowners.

More energy efficient:

According to experts, almost 70 percent of the energy used by geothermal HVAC systems comes from renewable energy sources within the earth. A geothermal HVAC system which is energy-efficient is approximately seventy five percent more competent in comparison to an oil furnace, 40 percent more competent when compared to a gas furnace and 43 percent more efficient when it is operated in the cooling mode.

More economical:

While the installation cost of geothermal systems is at the higher side, the HVAC system will gradually pay for itself as it will reduce the monthly utility bills and decrease your annual cost or maintenance. In comparison to a conventional system, you will get a much higher investment return when you buy a geothermal system.

Environmentally sustainable:

Geothermal cooling and heating systems are known to be one of the safest option available in the market when you keep environmental friendliness in mind. In fact, if you install a geothermal HVAC system in your residence, you basically plant seven hundred and fifty trees or reduce pollution amounting to two running vehicles.

Moreover, a geothermal residential HVAC system does not require fossil fuels to function, which is great for the environment as it eliminates threats resulting from combustion. If you invest in a geothermal system, there is absolutely no need to worry about carbon monoxide or the dangers it poses to the safety of your family.
