DWH Unit


With utility cost on the rise, finding a more efficient way of heating water has become a necessity. Water heating cost for many customers is a major expense. The DWH series of dedicated water heaters heat water with utility savings of 50-80% over conventional methods.

Using heat pump technology the DWH unit uses a small amount of electricity to harvest renewable heat from the sun. Both the heat from the ambient air absorbed and the electricity consumed are transferred into the water at significant savings over conventional water heating methods.


There are two models:
DWH Unit

DWH134A – utilizes 134A refrigerant and a double wall plate heat exchanger to heat domestic water up to 140F.


DWH Unit

DWH410A – uses the high efficient 410A refrigerant for pool heating applications where final temperatures less than 110F are satisfactory.
