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.

Geothermal heating and cooling systems do not require the use of fossil fuels to function, and harness earth's natural energy to deliver heat throughout your space.

A geothermal heat pump (also known as a ground source heat pump) draws thermal energy from underground. As a result, energy costs are low. However, a geothermal system has much higher upfront installation costs than a propane heating system. Additionally, the installation process for a geothermal system is complex.

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.

For water heating, you can add a desuperheater to a geothermal heat pump system. A desuperheater is a small, auxiliary heat exchanger that uses superheated gases from the heat pump's compressor to heat water. This hot water then circulates through a pipe to the storage water heater tank in the house.

Propane is one of several components derived when crude oil is refined (broken down). But propane is also one of the gases present in natural gas. Like natural gas, propane gas burns cleanly. It can actually help reduce the amount of greenhouse gases released into our atmosphere!

For anyone looking to save money on electricity bills, installing solar energy is the way to go. You can use a residential geothermal energy system for your home climate needs, but it will not produce electricity to run all of your appliances like a solar energy system.

Yes – a Geothermal Heat Pump can provide both heating and cooling functionalities, along with providing a low cost, hot water supply all year round.

During the winter a geothermal system absorbs this extra heat from the earth and transfers it into your home. During the summer the system takes heat from indoors and moves it back underground. Annual

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.

Geothermal fluid temperature should be at least 300°F/149°C, although plants can operate on fluid temperatures as low as 210°F/99°C. Learn more about power plant types and see illustrations of each on the Electricity Generation page.
