Water-or-Geothermal-to-Water Heat Pumps for Space Heating

Water-or-geothermal-to-water heat pumps extract heat from a flowing source of low-temperature water. They then deliver that heat to another, higher-temperature water stream for space heating.

Details include:

  • Various sizes: individual unit sizing 3-300 tons
  • Ambient conditions do not impact operation
  • 4-pipe configuration: heating/cooling operation via 2 pipes (changeover heating/cooling) + 2 pipes connected to source
  • 6-pipe configuration: simultaneous heating and cooling operation via 4-pipe configuration (dedicated cooling and heating piping) + 2 pipes connected to sources
