ROTEX G-plus – the gas-fired condensing back-up heater

Wall-mounted gas-fired condensing boiler unit as a back-up heater for the ROTEX HPSU compact air/water heat pump.

With an economically configured heat pump, additional energy will be required when outside temperatures are extremely low.

Instead of using an electric back-up heater, the required energy can be supplied with the new gas-fired condensing unit ROTEX G-plus. It backs up the heat pump when required, so there is no need for additional electric immersion heaters.

This significantly reduces the primary energy requirement for back-up heating and increases the energy efficiency of the heat pump.

ROTEX G-plus is a gas-fired condensing boiler which modulates its output variably in the range from 3.5 to 15 kW, so the required output is always adjusted variably in accordance with current needs.

The intelligent control unit of the HPSU compact performs all the relevant energy management functions, switching the ROTEX G-plus off and on and modulating it as required. So you can be sure that there is always enough heat to warm your rooms and heat your hot water – and that the entire system will be running at optimum efficiency.

This combination is ideal for renovations where there are existing gas connections or in new buildings where electrical connections are limited.
