Energy Efficient

Energy Efficient

WaterFurnace systems are rated number one in energy efficiency because they can deliver more than five units of energy for every one unit of electrical energy used. Compare that to even the best ordinary system that delivers less than one unit of energy for every unit it consumes. That translates into an efficiency rating exceeding 530%, compared to the most efficient gas furnace which rates only 98%.

Cost Effective

Because of the extraordinary efficiency of a WaterFurnace system, most homeowners save more on monthly bills than they pay for the system. Any added investment over traditional equipment is usually recovered in just a few years, and many homeowners see a return on investment of 10-20% over the life of the system.


Because geothermal units aren’t subjected to the punishing effects of outdoor weather or fuel combustion, they last longer than nearly any other heating and cooling system. Geothermal units have an average equipment life of 25 years while the underground loop system has a rated material life of more than 100 years. Ordinary air conditioners, furnaces and heat pumps are rated for only 12-18 years.

Environmentally Friendly

Geothermal systems are the most environmentally friendly and energy efficient heating and cooling systems available. Geothermal minimizes the threats of acid rain, air pollution and the greenhouse effect, directly linked to the burning of fossil fuels. In fact, installing a single geothermal unit is the environmental equivalent of planting 750 trees or removing two cars from the road.

Quiet Operation

WaterFurnace systems don’t require noisy outdoor units.

Flexible, Multi-Purpose

One compact WaterFurnace unit provides heating, central air conditioning and supplemental domestic hot water for your entire home. Horizontal, vertical, and bottom-flow configurations are available for a wide range of home applications, including newly constructed as well as existing homes.

Superior Comfort

WaterFurnace units are designed to run more often at low speeds to provide stable temperatures throughout the home and help eliminate hot or cold spots. This is especially true with variable capacity units. They provide a comfort you need to experience to believe.

WaterFurnace 7 Series

The WaterFurnace 7 Series™ provides homeowners the ultimate in comfort and performance. This line is for those who accept only the best and is built using the latest technologies and highest standards. The 7 series is the geothermal industry’s first variable capacity residential unit and the only unit to surpass both the 41.0 EER and 5.3 COP efficiency barriers. These ratings are vastly greater than ordinary systems and 30% higher than current two-stage geothermal heat pumps.


WaterFurnace 5 Series

The WaterFurnace 5 Series provides forced air heating, air conditioning, and even generates a portion of your home’s hot water – all from a single unit that offers a level of comfort and savings that’s far greater than any ordinary system. Available in many sizes and configurations, the 5 series provides exceptional performance, versatility, and quiet operation. All 5 Series products utilize environmentally friendly R-410A refrigerant and the best in system components.

WaterFurnace Synergy3D

With the Synergy3D Series, you’ll enjoy energy savings on your heating and cooling costs while providing hot water for radiant floor heat. The Synergy3D is the geothermal equivalent of a boiler, furnace and air conditioner – all in a single unit. Synergy3D units utilize ozone-safe R-410A refrigerant. Variable speed ECM blower motors are used for quiet operation. A sophisticated microprocessor control sequences all components during operation for optimum performance, and provides easy-to-use troubleshooting features with fault lights and on-board diagnostics. To help achieve ultimate comfort, heating priority may be given to forced air zones or radiant floor heat. Whether you choose to use radiant heat in small zones like bathrooms and the kitchen, or in larger zones like the basement floor, the Synergy3D delivers.

In 2014, The Hayter Group was recognized for being a WaterFurnace Dealer for 30 years.
