Geothermal power offers the best green deal for home heating currently. The power comes from a range of different underground sources, including shallow ground, warm underwater springs and liquefied rock in the form of magma that lies far beneath the earth’s crust.

Though, geothermal power has received a lot of notoriety of late, it has been used for thousands of years. Geothermal heats reach temperatures of up to 600 degrees f and have been providing electricity in the US for over 50 years, though on a large scale. They are also limited to specific areas.

Who can Use a Geo Thermal Pump?

However, new homes often install geothermal heat pumps. These pumps don’t need the deep drilling the large-scale plants do. Water is heated in relatively shallow ground and can be used for heating a large percentage of a home’s water and so saves on this energy intensive task.

Geothermal is perfect for new builds, though it can also be added quite easily to homes under renovation. However, in the latter case duct work, the previous heating/ AC system and other engineering details may come into play before it can be certified a good green deal.

Geothermal pumps use the constant heat of the soil below the frost line to heat the water. This ranges between 45 degrees f and 75 degrees f and so is either cooler than the summer air or warmer than the winter air. This means geothermal pumps can be utilised to cool or heat a home depending on the equipment used.

Makings of the System

The pump is made of three major parts:

  • Earth Connection Subsystem – This is an area of pipes that loops and covers the area of ground underneath and around the house and is filled with water or a mix of anti-freeze and water. This absorbs or radiates heat depending on the soil temperature.
  • Pump Subsystem – Removes the heat from the liquid and then distillates it. It is then used to heat the house. If the opposite is done then it cools the home.
  • Distribution Subsystem – Duct that distributes hot or warm air from the pump to the house

Reliability

Though geothermal heat pumps are quite expensive it is thought that the cost of its outlay is returned in under 10 years of operation. The US Government considers heat pumps as one of the most environmentally friendly and cost-effective manner of temperature control.

Geothermal pumps also come with a 50-year warranty in many cases meaning there is little to worry about in terms of reliability either.

Geothermal pumps are a great solution to heating worries and can provide a significant saving for your home in both green and monetary.
