nhwNHW 502W12 Geothermal Boiler Replacement
Capable of 150°F water output, the 5 Series 502W12 makes upgrading to a WaterFurnace geothermal system easy, particularly where the replacement system must work with existing cast iron or baseboard radiators.


7 Series

7 Series 700A11 Variable Speed Geothermal System
The 700A11 signifies groundbreaking innovations on multiple fronts – most notably as the geothermal industry’s first fully launched variable capacity residential unit and the only unit to surpass both the 41.0 EER and 5.3 COP efficiency barriers.


syn3dSynergy3D Geothermal WaterFurnace
Superior comfort and incredible performance are the hallmarks of the Synergy3D system. The unit provides forced air heating and cooling to ducted zones, while also providing hot water to radiant floor zones. It’s like a boiler, furnace and air conditioner all in one, working synergistically to provide the ultimate in comfort.



Legend Geothermal WaterFurnace
The Legend Series can lower annual heating and cooling costs by as much as 60%. Ordinary systems operate at a fraction of the efficiency of the Legend Series. And with the constantly rising costs of fossil fuels, savings potential will only increase. The graph below illustrates comparisons of various systems.


Versatec Ultra Geothermal WaterFurnace
The Versatec Ultra Series represents a significant improvement in the commercial water source heat pump (wshp). The product features high efficiency with industry leading standard options in a compact cabinet suitable for both retrofit and new construction applications. It is also designed to provide optimum performance and flexibility in both water loop and geothermal applications.


Envision NSW Series Water-to-Water
Hydronic heating and cooling systems have long set the industry standard for comfort and flexibility. Whether the application includes radiant floor heating, forced air fan coil units, domestic hot water heating or process heating/cooling loads, the NSW Series can fit every application from the simple to the complex. The NSW also can supply hot water for pools, spas and ice melt under sidewalks and driveways.


Envision Split System
Have you recently installed a new furnace and are still shocked at the cost of your energy bills? The answer is a geothermal split system by WaterFurnace. You can get into a high-efficiency geothermal system, without having to replace your whole fossil fuel furnace, because the two can work together.


The WaterFurnace GeoTank is simply the best way to capture preheated water from your unit. Engineered specifically for your WaterFurnace geothermal system, the GeoTank includes unique features that make installation and operation easy.


Envision NDW Series Water-to-Water
The Envision NDW Series can reduce water heating costs by as much as 60% per year. Ordinary boilers and water heaters operate at a fraction of the efficiency of the NDW Series. With skyrocketing costs of fossil fuels, savings potential will only increase. The graph below illustrates comparisons of various water heating systems.

poolhtrEnvision Series Pool Heater
With more than 20 years in the design anf manufacture of the highest quality geothermal systems on the market, WaterFurnace quality is now available to heat pools without an earth loop. Advanced design and premium components acheive a 25% increase in operating capacity over other leading heat pumps - saving you money. Operating costs are 60% less than natural gas!




Helping to provide an unbeatable earthloop system, Environol Anti-Freeze is the environmentally friendly solution for keeping your geothermal system running at its peak all year round.  Even through those cold winter nights!




Polyethylene Pipe and Fittings
This high density, corrosion-resistant pipe has become the choice of today's leading contractors for constructing geothermal earthloops.  With both pipe and fusion fittings available, you will be able to find what you need for all of your earthloops.




DustFighter 95 Electrostatic Filters
Capturing 95% of household pollutants has become the new standard for filter efficiency.  This series of electrostatic filters provides the cost-conscious consumer with an inexpensive solution to cleaning the air, and saving money.




IntelliZone Comfort System
Being able to control the climate in different rooms of the same building with only one heating/cooling unit is now made possible with the IntelliZone Comfort System.  Combining an IntelliZone with an already amazingly-efficient geothermal WaterFurnace unit can result in even more savings.



Intellistart Soft Starter
the IntelliStart system reduces the start up current (locked rotor amps) of a geothermal compressor by up to 70%. When a compressor starts, it has a very large and short spike of amps to start the compressor and then it drops down to normal.
