Domestic hot water heating with photovoltaic integration

The HDG BRWP 300 domestic hot water heat pump provides domestic hot water heating and can be connected to a photovoltaic system. Electricity generated by the photovoltaic system can be used to operate the heat pump. The unit draws in ambient air and discharges cooler, drier air. Depending on installation conditions, this may contribute to reduced humidity levels and a cooling effect in the installation room.

Extensive equipment

  • Robust HD steel tank with high-quality enamel coating, designed to support a long service life
  • Standard signal anode for corrosion protection
  • Can be operated with room air or outside air (-10°C to +35°C)
  • Additional heat exchanger for connection of further heat generators (e.g. wood boiler or solar thermal system)
  • CFC-free thermal insulation with standby heat losses of approximately 20 W
  • Hygiene function with legionella programme

Advanced control technology

  • Smart Grid Interface for connecting photovoltaic systems and multi-tariff meters for coordinated operation of the domestic hot water heat pump
  • Boost function for short-term increased hot water demand via the integrated electric heating element
  • Timer function for individually adjustable operating times of the domestic hot water heat pump
  • Holiday function for operation during periods of absence

Transport and installation

  • Can be integrated into a wide range of boiler rooms thanks to its low space requirements and installation height
  • Plug-and-play installation with pre-configured control system supports quick commissioning and user-friendly operation
