High efficiency air-to-water heat pump for outdoor installation incl. domestic hot water preparation.

  SG Ready

Heating package comprising a high efficiency air-to-water heat pump for outdoor installation and Hydro-tower HWK 230Econ5S with integrated heat pump manager.

Heat pump

  • Extremely quiet thanks to sound-optimised casing and sound-insulated compressor housing
  • High efficiency thanks to high-performance evaporator, EC fan and COP booster
  • Integration of intelligent room temperature controllers (Smart RTC) enables a further increase in system efficiency
  • Flexible expansion options via 2 mixer outputs for bivalent operation and/or the control of mixed heating circuits
  • Use of load-variable tariffs (SG Ready)


  • Minimal installation effort thanks to the space-optimised combination of buffer tank and domestic hot water cylinder
  • Simple commissioning with integrated heat pump manager and optimally coordinated hydraulic components
Electronically controlled circulating pump for the generator, heating circuit, energy efficiency EEI ≤ 0.20; heating circuit free compression 40200 Pa at 1.15 m3/h.
  • Demand-based supplementary heating via additional heating (2 kW)
The electrical connection between the heat pump and the Hydro-tower takes place via a shielded 2-wire data cable (e.g. LiYY; cross-section 0.6 mm²) not included in the scope of supply (Spectrum of efficiency classes A+++ to D)

Seal of approval EHPA

European Heat Pump Association - EHPA
