So what is WaterFurnace®?

Water furnace heating and cooling, also referred to as geothermal or ground water, has been used to heat and air condition buildings for several decades. It is the use of geothermal heat pump technology to tap the energy in the earth’s surface and drive a heating and air conditioning system for both residential and commercial uses. The result is a green or natural heat pump that saves energy and benefits the environment.

Geothermal Loop Systems

Geothermal Heating and Cooling

No matter what climate you live in, the temperature throughout the year varies. For some climates that means blazing summers that cool to frigid winters. What many people don’t realize is that the temperature below ground (regardless of climate or season) stays fairly consistent all year.

The ground is able to maintain a higher rate of temperature consistency because it absorbs 47% of the suns energy (heat) as it hits the Earth’s surface. WaterFurnace® geothermal systems are able to tap into this free energy with an earth loop. This technology is then used to provide your home or office with central heating and cooling.

Geothermal Heating

As the system pulls heat from the loop it distributes it through a conventional duct system as warm air. The same heat energy can also be used for a radiant floor system or domestic hot water heating.

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.

Geothermal vs. Geoexchange: What’s In a Name?

Geothermal energy has been used to heat and air condition buildings for several decades, and during that time these geothermal systems have been called many different things. Some of the more popular variations include geo-thermal, geoexchange, ground-water, ground-water assisted, ground-water-source, water-to-water, and even our company name, water furnace heating and cooling.


Geothermal Loop Types

There are four basic types of geothermal energy sources. Your property’s size and features will determine which loop types are options for your geothermal system.

Horizontal Loops

Vertical Loops

Pond (Lake) Loops

Open Loops

Geothermal Tax Credits

An exciting new tax credit is now available for home and commercial building owners who install geothermal heating and cooling systems through the Energy Improvement and Extension Act of 2008 (H.R. 1424). H.R. 1424 offers a onetime tax credit of 30% of the total investment for homeowners who install residential ground loop or ground water geothermal heat pumps. A credit of 10% of the total investment is also available (no maximum) for a commercial system installation.

To qualify, the systems must meet or exceed EnergyStar requirements and be installed after December 31, 2007. While units installed in 2008 are subject to a $2,000 cap on the credit, units installed from 2009 through 2016 can take advantage of the full credit. Owners can file for the credit by completing the Renewable Energy Credits subsection on their tax return forms for 2008. For taxpayers that are subject to the Alternative Minimum Tax, they can claim the credit on their taxes for the following year. No proof of purchase will be required; however, in case of an audit, owners are encouraged to keep a detailed invoice of their purchase on file. The contractor who sold and installed the product should list the purchase as a “Geothermal Heat Pump” on the invoice and that it “Exceeds requirements of Energy Star program currently in effect”.

The tax credit is available through December 31, 2016. Consult your local tax professional for advice on taking advantage of the tax credit, as this announcement is not intended as a recommendation or endorsement of any financial strategy.
