ROTEX HPU HYBRID

From the jury's assessment

The new hybrid combination by ROTEX is called “ROTEX HPU hybrid“, and is especially efficient, comfortable and reliable. The new ROTEX HPU hybrid combines a regenerative air-/water heat pump with energy-efficient gas-fuel value technology. The inner unit of gas-condensing boiler and heat pump interior unit normally don’t need more room than a conventional gas boiler. With flow temperatures between 25 °C to 80 °C the ROTEX HPU hybrid is suitable for any type of building. The ROTEX Hybrid Logic Control always chooses the cheapest mode depending on the current price for electricity and gas.
