Products for heat pumps

Custom-made, fully insulated OEM products with sensor pockets and heating coil connections in the side of the cylinder, makes these units the perfect companion for heat pumps. The units are purpose-designed for heat pumps with the possibility of prioritizing domestic hot water (DHW) production. The extremely large heating coil of 1,4 / 1,8m² is perfectly dimensioned for heat pumps up to 10 / 12 kW, and will provide the heat pump with optimum working conditions.


The OEM heat pump units are able to provide up to 60% of annual DHW requirements from an air-source or ground-source heat pump. The units ensures the lowest possible temperature difference between the heat pump and DHW, providing higher Coefficient of Performance (COP). The electric heater (3kW) is located above the heating coil to provide two temperature zones, utilizing the heat pump in an optimum way. Temperature from the heat pump is typically 55-60°C, and the electric heater ensures sufficiently high temperature for avoiding bacteria growth. Separate ½” sensor pocket for precise control from the heat pump is factory fitted. Low heat loss is provided by ECO Foam, with impressive key figures for GWP of 1 (Global Warming Potential) and ODP of 1 (Ozone Depletion Potential.)


Customer specified connection sizes / placements and heating coil size are also available. For the perfect DHW heat pump cylinder, look no further.

Key advantages:

  • The ultimate DHW cylinder for heat pumps up to 12kW
  • Purpose designed with key features for ground and air source heat pumps
  • 10 year warranty on the stainless steel inner cylinder & ECO Foam insulation
