The real feachuers on the Fusion range are the Truma Combi heating system. Whilst, the Truma may well be the smallest heating system in Europe! However, it works with both gas and electricity. On the Fusion range it is fitted as standard equipment. This all comes with the frost control. The water heats up quickly and there is ample hot water for showers, There is a new control unit called CP PLUS. This works on a collision sensor that cuts off the gas supply in case of accident. The Boiler provides the heater system, a Combi 4 (Opt Combi 6, Combi 6E, and Combi 6 Diesel) Heating with channelled air.

The central heating system, is a proven way to heat motorhomes. It works on the same principle as heating a modern home. Quality heating. with convectors and radiators along the outer walls, and pipes in floor. It is a very clever system and starts by heating up the air. This then heats up the furniture and surfaces. The warm air acts as a barrier in front of the windows, keeping the cold out, with the heat remaining inside. There is frost control and a drain/safety valve fitted as well. The control panel is on a touch screen and easy to operate. The boiler has a built-in heater. Thus this ensures that hot water in the shower and kitchen, is always available.
