5 Series

The WaterFurnace 5 Series™ complete heating and cooling solution.

Versatile and Reliable

The WaterFurnace 5 Series is available is several sizes and configurations. This premium geothermal heat pump is suitable for almost any home in our climate zone.

Two Speeds
For Comfort and Efficiency

The WaterFurnace 5 series operates at either high or low. Most of the time it runs at low speed to keep consistent temperature throughout your home. When we are getting extreme hot or cold weather, it will kick into high speed to keep up with demand.

Energy Savings

The WaterFurnace 5 Series saves you energy in both heating and cooling season. In the summer, it's twice as efficient as a traditional air conditioner. In the winter, it's 5 times more efficient than typical gas, oil or propane furnaces.

WaterFurnace 5 Series - Geothermal Heat Pump

WaterFurnace 5 Series

Heating and Cooling

Your WaterFurnace 5 Series provides you with both heating and cooling, quietly and efficiently. You can get rid of your unsightly and noisy outdoor air conditioning unit.


Unlike gas, propane, wood or oil furnaces, there is no open flame with a WaterFurnace geothermal heat pump. There is not carbon monoxide gas to worry about. Your heat pump does not need to be ventilated to the outside.

Hot Water Assist

The WaterFurnace 5 Series can preheat your water with an optional hot water assist. The warmed water is delivered to your water heater. A microprocessor controls and monitors your heat pump and determines when there is excess heat available to assist with heating your hot water. This allows you to utilize the earth's energy for domestic hot water as well.

Improved Air Quality

Large, high efficiency MERV 11 filters come standard on the WaterFurnace 5 Series to provide exceptional indoor air quality, protecting your family from dust and allergens.

Because your unit runs more often, at a lower quieter speed than a traditional furnace, your home's air is filtered more often.

Optional Washable Filter

The Hayter Group offers an electrostatic washable filter as an option. Electrostatic filters use static electricity to remove up to 90% of pollutants in your home's air. There is no electrical connection for the filter. It operates on the same principle as a comb rubbed up against a sweater. The static charge in the filter attracts particles in the air to the filter's media.
