hot water with HGL technology

The iDM heat pump with HGL offers not only twice the comfort, but also helps to save additional sources of energy and the associated costs. iDM heat pumps work without a concealed additional immersion heater – cost-effectively and in an environmentally friendly way – for a lifetime. This is because this innovative technology is very sparing with your energy. It ensures a temperature of 60°C for hot water (at a supply temperature of 35°C) thanks to optimum operation of the heat pump without any energy loss.

• 85% of the energy generated by the iDM heat pump with HGL technology is fed into the heating circuit at 35 °C.
• Thanks to HGL technology, the remaining 15% can be used cost-effectively and efficiently for domestic hot water production, providing temperatures of up to 62 °C.
• This ensures fresh hot drinking water is available within seconds.
• Only heating water is stored in the Hygienik tank; the domestic hot water is always freshly heated.
• This prevents the formation of legionella and other bacteria.

*) The 62 °C refer to the maximum flow temperature of the heat pump. The resulting lower domestic hot water temperature must be evaluated in relation to compliance with drinking water regulations.
