NORDIC® W Series - Liquid to Water
Liquid to water - for use on open water wells and closed ground loops - hot water output up to 120°F (49°C) - for in-floor heating, pool heating or any other hot water requirement.
W Series units are high efficiency two-stage geothermal heat pumps with R410a refrigerant. Two stage units offer a significant efficiency increase over single stage units when operation in the reduced capacity mode. This product is designed to produce large quantities of hot water. It can be installed on either open well systems or on closed loop systems. The model comes standard as a reversible heating/cooling system with domestic hot water desuperheater. It is very popular for use with concrete in-floor heating systems, swimming pool heating, or any other application where large quantities of hot water are required. Units are available in capacities from 24,000 Btu (2 ton) up to 72,000 Btu (6 tons)
