EW Water-to-Water

For outstanding versatility and efficiency, the EW Series Water-To-Water comfort systems are the smart choice for your home’s radiant floor heating, domestic water heating, pool or spa heating, and even snow melt applications. With EW Water-To-Water comfort systems, there are no concerns about flames, fumes or carbon monoxide -- just safe, clean, quiet and reliable performance for your home and family. Sophisticated microprocessor controls and state-of-the-art components ensure many years of virtually maintenance-free high-efficiency operation. You can take pride in knowing you’re protecting the environment, because the EW Water-To-Water comfort system uses the environmentally safe R410-A refrigerant.

Providing superior comfort without burning fossil fuels, EW Water-To-Water geothermal systems utilize unlimited free energy found naturally in the earth. As a result, EW Water-To-Water systems operate at much higher efficiencies than traditional boilers or other water heating devices. Some EW series units feature dual capacity compressors, allowing the unit to run in two stages increasing your energy savings –- first stage for mild weather, second stage (full capacity) for the coldest and hottest days of the year. These high-efficiency systems can dramatically reduce your operating costs, helping you save up to 60% on your monthly utility bills over ordinary systems. For example, even the most efficient gas furnace returns about 90¢ in energy for every dollar in operating costs. The EW Series will return $3 to $4 worth of energy for every dollar it uses.

The EW Water-To-Water comfort system can fit every application from the simple to the complex. Hydronic heating and cooling systems such as the EW Water-To-Water, have set the industry standard for comfort and flexibility. EW Series Water-to-Water units excel at providing the following home solutions:

 

Radiant Floor Heat

An in-floor radiant heating system operates by circulating warm water through a series of pipes embedded in the floor. Acting as a giant radiator, the floor generates warmth to bodies and furnishings without those hot blasts of air commonly associated with gas, propane and oil furnaces. Your feet and furnishings stay warm through conductive heat, while the air passing over the warm floor provides additional convective heat. The warmth of radiant heat provides superior comfort. Because the piping system is encased in the floor, furniture can be arranged however you choose without concern for blocking register vents. Other radiant heat applications requiring hot water, including wall- or floor-mounted radiators, may also be used.

 

Domestic Water Heating

Systems can be designed to generate an abundant supply of hot water, created efficiently without the need of fossil fuels. Whether it's for a residential or commercial application, the EW Series Water-to-Water unit can keep you in hot water.

 

Pool and Spa Heating

With efficiencies three times that of conventional pool heaters, the system can reduce water heating costs for pools dramatically. Owners of outdoor pools in colder climates can now affordably extend the swimming season with an abundant supply of clean, efficiently-heated water.

 

Snow and Ice Melt

Using a series of pipes embedded in a sidewalk, driveway, or patio, warm water is delivered to the area to keep the surface safe-free of snow, ice and moisture.

 

Fan-Coil Systems

Some applications incorporate the use of fan-coil units where hot or cold water is passed through a water coil in an air handler to supply conditioned comfort. The EW Water-to-Water unit delivers the right temperatures of water to heat, cool and dehumidify.

 

Environmental standards for refrigerants are becoming more stringent. WaterFurnace was the first to develop a geothermal heating and cooling system using the environmentally safe and performance-enhancing R-410A refrigerant. R-410A will not harm the earth’s ozone layer, unlike other refrigerants used today. WaterFurnace geothermal systems don’t burn fossil fuels, so they don’t emit harmful greenhouse gases, which are associated with global warming. With the EW Water-To-Water Series, you’ll have the ultimate in comfort, efficiency and performance, while doing your part to protect the environment.

Because WaterFurnace geothermal systems don’t burn fossil fuels, they don’t emit harmful greenhouse gases, which are associated with global warming – you’re doing your part for the environment. No flames. No fumes. No odors. No danger from carbon monoxide in your home. You’ll benefit from improved indoor air quality and less dust.

Designed to provide you with years of coverage and protection, our Worry-Free Warranties are a great complement to the quality built into your WaterFurnace system. Our warranty coverage is more than a piece of paper… it’s peace of mind. Every Waterfurnace is covered by a Manufacturers’ warranty, instead of by a third party. Our standard warranty covers unit parts and accessories for 10 years. WaterFurnace Dealers receive a repair/replacement labour allowance on warranted components. Other warranty options are available. Check with your independent WaterFurnace dealer for details. To learn more about the warranties offered, be sure to visit our WaterFurnace Warranty section.
