EKW Hydronic Heat Pump System
Comfort, Versatility, WaterFurnace Reliability
Hydronic heating and cooling systems have long set the industry standard for comfort and flexibility. Whether the application includes radiant heating, forced air fan coil units, domestic hot water heating or process heating/cooling loads, the EKW Series can fit every application from the simple to the complex. Sophisticated microprocessor controls and state-of-the-art components ensure many years of virtually maintenance-free operation. The EKW also can supply hot water for pools, spas and ice melt under sidewalks.
Because it doesn´t burn fossil fuels, the EKW Series emits no harmful greenhouse gases, which are associated with global warming. No flames. No fumes. No odors. No danger from carbon monoxide. Less dust and better indoor air quality. The WaterFurnace EKW Series is the best in the business.
