Geothermal Heating/Cooling

Geothermal heating/cooling is an environmentally friendly way of harnessing the earth's temperature while leaving a very small carbon footprint. As the trend to become more energy efficient and environmentally friendly has increased dramatically we have also looked at the new ways to help the environment.

By providing geothermal heating and cooling solutions, products and services, we are helping the environment in our own way. Please contact us if you have any questions regarding any aspect of Geothermal Heating/Cooling.

What is Geothermal or Geoexchange?

GeoExchange is the industry's term used to describe an alternative to traditional oil- gas- or coal-fired heating, ventilation and air conditioning (HVAC) systems. Geoexchange systems have also been referred to as earth energy systems, geothermal heat pump systems, or ground source heat pump systems (GSHP).

The idea is to take advantage of the ground's heating and cooling properties (the same properties that make any basement cooler in the summer and warmer in the winter) to heat or cool entire buildings. This heat 'exchange' between the ground and the building is accomplished by using standard pump and compressor technology.

The advantages of geoexchange technology include: Geoexchange technology can save the developer or consumer up to 70% on their current heating bills, because it transfers existing heat without combustion, Geoexchange often pays for itself in less time than a traditional HVAC system, depending on current building heat/cool use, soil types, size of installation, and other factors.

Geoexchange qualifies as a renewable energy - a typical two bedroom house-sized installation is equivalent to taking two cars off the road or planting one acre of trees. Geoexchange systems involve no combustion, so they are cleaner and safer to handle than either oil or gas.

Geoexchange takes up much less space than traditional HVAC systems, they are particularly suitable for situations where space is at a premium and/or aesthetics matter.

What can I do with GeoExchange?

You can heat your home with radiant in-floor, forced air, or a hybrid system utilizing both.

One of the great advantages to GeoExchange forced-air is that the equipment is capable of both heating and cooling. No outdoor air conditioning units required to cool the home. The biggest advantage to the homeowner when both heating and cooling through the year with GeoExchange is increased efficiency and less equipment required. Also, since the GeoExchange heat pumps are designed to be installed indoors, they are quiet, clean, and easily serviceable since they require no fossil fuels to operate.

Hydronic in-floor radiant heating is an excellent match for ground source heat pumps. The water temperature designed to be distributed through in-floor radiant is approx 80F to 120F. This is the same temperature of water that geoexchange heat pumps can provide at a very high operational efficiency.

The heat pump can replace a boiler (electric or gas-fired) in many cases and provide the hot water required. This could be used for snowmelt (radiant in-floor for your driveway), hot tub/pool heating, or heating your greenhouse or garage. In cases where higher temperatures are needed, the majority of the energy can be contributed by the GeoExchange heat pump and then temperature increased slightly with the use of a supplementary heating source.

Heating domestic hot water with GeoExchange can be very simple. Almost all heat pump manufacturers include the option for hot water generation, also known as a desuperheater. It has been advertised as boiler "free" water heating, but this is not entirely accurate. While the heat pump is running in heating or cooling mode the desuperheater pump will also be circulating creating preheated (warm) water and delivers that heated water to the hot water tank or tankless water heater where it can then be fully heated. This works best in cooling mode, where otherwise this heat would have to be put back into the ground loop.
