Login, contact dealer or request account for pricing

The High Temp W-Series water-to-water heat pump is designed to boost temperatures of water pre-heated by conventional ground source water-to-water heat pumps (or other sources such as Solar Thermal applications) to temperatures hot enough for Domestic Hot Water applications and/or baseboard or other heating distribution configurations that require water temperatures above 120F.

The SOURCE Side (or ground loop side) water temperatures should be between 45°F (7°C) and 90°F (32°C).

The LOAD Side (or Hot side) boosted water temperatures can reach up to 160°F (71°C) and should be a minimum of 20°F higher than the Source side. Consult manual for details.

NOTE: the 7.5 ton series (WH-85) have double walled brazed plate condensers specifically designed for domestic hot water usage. All other series have copper condensers not rated for domestic hot water.
