Our C-Series is a high-efficiency water-to-water heat pump water heater that can be tailored to your needs in several ways. These units range in capacity from 25,000 BTU to 250,000 BTU, generating from 50 to 500 gallons of hot water per hour.

While these units are heating water up to 150°F, they are also providing cool water on the source side that can be used for chiller water for air conditioning systems or process water for equipment.
