Cool & Comfortable

Geothermal heating (known as Ground Source Heat Pumps, or GSHP’s) at its most basic is just transferring heat energy between the Earth and your home. In the winter when you need to heat, you simply transfer the heat from the earth into your home. In the summer when you need to cool, it is just the opposite; heat is taken from your house, and put back into the earth.

Geothermal systems can be installed basically anywhere, and have no need for natural hot springs or geysers under your house. This system just uses a heat exchanger in the earth to transfer the heat energy.

The United States E.P.A. has called ground source heat pumps "The most energy efficient, environmentally clean and cost effective space conditioning system available.”

Geothermal Heating Explanation

Heating Process

Geothermal heating simply pumps heat from the earth into your home. A liquid is circulated through a large loop(s) in the ground called a ground loop. While that liquid is traveling through the pipe buried in the ground, it absorbs the heat from the surrounding ground. That liquid then carries the heat to the heat pump, which acts similar to a refrigerator in taking that heat through a refrigerant cycle inside the heat pump, and discharging it to your home heating distribution system (forced air or radiant floors). Unlike traditional systems that burn fuel or rely on outside air, geothermal works smarter—not harder—no matter the weather.

Cooling Process

Geothermal cooling works the same as geothermal heating, except in reverse. Heat is taken out of the structure in the home, put into the circulating liquid inside the ground loop, and absorbed into the cool earth. This “reversed” cycle is simple to switch a heat pump into with its reversing switch. When a ground source heat pump is in cooling mode it is functioning the same as a refrigerator, pulling heat out of the house, putting it through a refrigerant loop, and then expelling it out. A refrigerator does that using the coils on the back. A GSHP does it using the large earth loop and cool mass of earth, making it more efficient to have heat go to cold instead of hot ambient air.

Water Heating

As a by-product of the natural function of the heat pump, hot water can be produced for the domestic hot water load of the household. Using a “desuperheater” addition to the heat pump, you are able to capture the excess heat from the compressor that may otherwise be lost in the cabinet of the heat pump, and pump it straight into your home’s hot water heater. This helps reduce costs of heating the hot water tank, which can directly save you money.

Ground source heat pumps can also be configured with a dedicated hot water coil for on demand water heating. This double walled heat exchanger differs from a desuperheater in that it operates when there is a “call” for heat from in the domestic water tank.

For most residential applications where there is a lower domestic hot water load the desuperheater is the more economical choice. In applications where there is a significant domestic water heating loads the dedicated hot water coil can be considered.
