A geothermal system uses small-diameter, High-Density Polyethylene (HDPE) pipes buried underground called a "loop." The loop circulates water to move heat energy to and from your home. It's the heart of a geothermal system and its biggest advantage over ordinary heat pumps, air conditioners and fossil fuel furnaces.

WaterFurnace residential geothermal heat pumps keep homes comfortable in every climate. That's because we unlock the free, renewable solar energy that's stored in the ground. WaterFurnace delivers comfort the natural way - and cuts your energy bills by up to 70% in the process.

For every unit of electricity the system uses, it provides three to four units of heating energy - an efficiency of 300% to 400%. Geothermal systems can also provide increased energy security protection from inflation in the cost of volatile fossil fuel (natural gas) commodity prices.

All ENERGY STAR certified geothermal heat pump models are recognized as Most Efficient, as they deliver superior performance, particularly when it is very cold or very hot.

Geothermal energy is heat within the earth. The word geothermal comes from the Greek words geo (earth) and therme (heat). Geothermal energy is a renewable energy source because heat is continuously produced inside the earth.

Hot water is pumped from deep underground through a well under high pressure. When the water reaches the surface, the pressure is dropped, which causes the water to turn into steam. The steam spins a turbine, which is connected to a generator that produces electricity.

renewable energy Geothermal energy is a renewable energy source because heat is continuously produced inside the earth. People use geothermal heat for bathing, for heating buildings, and for generating electricity.

A WaterFurnace geothermal system operates more efficiently than ordinary heating and air conditioning systems because it can deliver an astounding five units of energy for every one unit of electrical energy used.

Geothermal heat pumps are among the most efficient and comfortable heating and cooling technologies available because they use the earth's natural heat to provide heating, cooling, and often, water heating.

Geothermal power plants do not burn fuel to generate electricity, but they may release small amounts of sulfur dioxide and carbon dioxide. Geothermal power plants emit 97% less acid rain-causing sulfur compounds and about 99% less carbon dioxide than fossil fuel power plants of similar size.

A WaterFurnace geothermal system operates more efficiently than ordinary heating and air conditioning systems because it can deliver an astounding five units of energy for every one unit of electrical energy used.

Geothermal provides a reliable source of energy as compared to other renewable resources such as wind and solar power. This is because the resource is always available to be tapped into, unlike with wind or solar energy.
