The C-Series Water Source units are highly efficient Water-to-Water Heat Pump Water Heating System that heats water by drawing energy from available source water. This method saves up to 75% in costs when compared to electric water heaters.

While these units are heating water up to 160°F, they also provide cool on the source side that can be used for chiller water for air conditioning systems or process water for equipment.

These are designed and manufactured in our state of the art facility located in Brewer, Maine. These units use various options to meet your application needs. They are suitable for drinking water applications with the standard NSF 61 approved double wall heat exchanger.

How Our Units Work

Our Water Source Heat Pump Water Heaters capture heat and humidity from source water and transfers that heat energy into a storage tank. In basic terms, Heat Pump Water Heaters move heat from where it is not needed, to where it is desired. These units provide low cost water heating and supplemental cooling that can be directed to where needed.

Suitable Application

Our Water Source Units range in capacity from 27,000 BTUH to 275,000 BTUH, generating from 50 to 500 gallons of hot water per hour. These units can heat water efficiently up to 160° F and are ideally suited for;

These units have a range of base model Heat Pump Water Heaters that can be customized to meet your application needs. Available options include, programmable logic controllers, Building management systems integration hardware, 304 or 316 stainless steel cabinets, and multiple voltages available.

C185W(Water Source)





Key Features and Benefits

» Leaving water temperatures over 160° F allows for consistent tank temperatures.

» Typically operating at COP’s from 3.0 to 5.0, meaning it is expected to save 60% - 75% versus the costs of running an electric water heater.

» Can be connected to most storage tanks and water heaters, including: Electric, Oil, Natural Gas, Propane and Solar tanks.

» Single and Multi pass options are available for different system configurations.

» Optional Programmable Logic Control (PLC) with BMS hardware allowing integration into your existing mechanical system.

» Integrated NSF 61 approved Stainless Steel circulator pump included.

» Uses environmentally friendly R-134a refrigerant.

» Can be used as preheat system when higher temperatures are desired.

» The cooler, leaving source water can be used as process water for equipment or air conditioning systems.

» Painted aluminum as well as optional stainless steel cabinet provides superior protection against corrosion. Coated coils for further protection come standard.
