Premium solution for constant heating and hot water in motorhomes

Hybrid 7/7E from Webasto is the most powerful solution for simultaneous heating and hot water in motorhomes. A 5.5 kW Air Top Evo 55 air heater powered by diesel from the vehicle tank quickly and constantly warms the interior, while a 1.35 kW Expanse gas or combined gas/electricity boiler (7E) heats water for washing and showering. The devices heat independently of each other so that their respective output is only available for heating or hot water preparation. This means that the heat is available extremely quickly. All devices can be installed both underfloor and onboard.

Webasto Air Top Evo 40/55 diesel air heater with integrated combustion chamber and directed outlet, providing efficient cabin heating as a systems partner.

Benefits of Hybrid 7/7E

Rapid heating

Thanks to the power-boost function, Hybrid 7/7E immediately ensures a warm interior and hot water, even in extreme climates.

Powerful heat output

With a combined heating output of around 7 kW, Hybrid 7/7E is ideal for larger motorhomes.

Continuous hot water

Thanks to the efficient heating system, a continuous supply of hot water is guaranteed even in winter.

Space and weight saving

As the heating system uses diesel instead of gas, the number of gas bottles on board can be reduced. This saves around 20 kg of payload and space.

Gas cylinder replacement reduced

Hybrid 7/7E extends the service life of the gas cylinders so that they need to be replaced less frequently.
