An alternative to the Eberspacher Combitronic, this Genuine Webasto water heater is typically mounted externally on the vehicle, whilst the header tank and plate heat exchanger utilise minimal interior space. The blower unit would be mounted in the area where the heat is most required i.e. living area and the rear. The 2 speed blower can operate independently or together & are controlled by a thermostat. Heating & hot water on the move is possible. The bypass (optional) is used for hot water only in order to achieve a quick heat up time.

Operation – Once activated, the Webasto Thermo Top Evo heater will use the vehicle’s own fuel in a combustion process to heat the coolant via a heat exchanger. The heated coolant is then circulated round the heating circuit passing through the fresh water plate heat exchanger & blower heater unit by an integrated water pump. The Webasto unit is self regulating & operates in a similar way to a domestic central heating system.
