High Temp WH-Series

Introducing: High Temp WH-Series heat pump

The High Temp WH-Series heat pump water-to-water heat pump produces hot water up to 160°F (71°C). It boosts temperatures of water that is pre-heated by other sources. This can be for example a conventional ground source water-to-water heat pumps an industrial process, or Solar Thermal applications. The output temperatures are hot enough for Domestic Hot Water applications and/or baseboard or other heating distribution configurations that require water temperatures above 120F.

The heat pump’s heat source is clean incoming liquid that has been pre-heated to between 45°F (7°C) and 90°F (32°C). Usually this heat source comes from a buffer tank on the indoor side of a geothermal heat pump. It can also come from a cooling loop in an industrial process. For example a Data Center or liquid cooled greenhouse. Using this pre-heated incoming liquid, our high temperature heat pump heats water to as high as 160°F (71°C).

Temperature ranges

The SOURCE Side (or ground loop side) water temperature ranges 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 the manual for details.

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

Incoming fluid too cold?

If you require up to 160°F (71°C) water temperatures directly from a closed ground loop source temperature as low as 30°F (-1°C), consider our Cascading WC-Series heat pump.
