Geothermal

A geothermal system operates more efficiently than ordinary heating and air conditioning systems because it can deliver up to 4 units of energy for every 1 unit of electrical energy used. Geothermal heating and cooling uses the crust of the earth to heat and cool a home or building. Geothermal works because the ground beneath our feet is warmer than the outside air in the winter and cooler in the summer. Ground temperatures are a fairly constant 50-60 degrees all year even though the ambient temperature varies.

Geothermal Heating

During the heating cycle, a geothermal heat pump uses underground pipes, called a ground loop to absorb heat from the earth and returns it the heat pump. The system then extracts heat from the liquid and it is then circulated through a conventional air duct.

Geothermal Cooling

In the cooling mode, the heating process is reversed – creating cool, conditioned air throughout the home. Instead of extracting heat from the ground, heat is extracted from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.

This is not a new technology, this is not a science experiment and this is not rocket science. In fact, geothermal heating and cooling is the standard in many European nations.  In Sweden and Switzerland, more than 75% of new homes have geothermal.

The EPA has acknowledged geothermal systems as the most energy efficient, environmentally clean, & cost-effective space conditioning systems available.

What are the benefits that Subsurface Construction can help provide you with the installation of a geothermal system?

Or simply “What are the benefits?”

Lower operating costs

The most efficient gas furnace has an efficiency rating of 94%. Geothermal delivers a 400% efficiency rating. 4 units of energy are delivered for every 1 unit of electrical energy. This does not bend the laws of physics; geothermal systems are transferring heat, not creating it by burning something. A more efficient comfort system lowers the bill significantly, up to 70%.

Quiet operation

Unlike ordinary air conditioners or heat pumps, there’s not a noisy outdoor unit to disturb your outside environment or your neighbors. Geothermal units are very smooth and quiet in operation.

Enhanced Comfort

Our geothermal systems provide precise distribution of comfortable air all year long, eliminating hot spots and cold spots. During heating, you’ll experience warm air without the hot blasts associated with ordinary gas furnaces, or the cooler air of an air source heat pump. Additionally, when cooling, our geothermal systems deliver cool, dehumidified air.

Reliable

Unlike air conditioners and heat pumps, geothermal systems are installed indoors, so they are not subject to wear and tear caused by rain, snow, ice, debris, extreme temperatures or vandalism. Geothermal systems have proven to be very reliable and require less maintenance.

Environmentally Friendly

According to the Department of Energy and the EPA, geothermal systems are the most environmentally friendly way to heat and cool your home. Our systems emit no carbon dioxide, carbon monoxide or other greenhouse gasses, which are considered to be major contributors to environmental air pollution. They are truly a natural, green heat pump.
