Dometic CH4000

Combo heater for cabin air and hot water, 4000 W, LPG

This powerful combo heater can independently heat air and water. Allowing you to enjoy the warm and comfortable temperatures inside your RV, as well as sufficient hot water for several showers in a row. Another benefit is the independent cabin vent function, which creates a pleasant indoor climate and helps prevent mold build-up in critical “cold spots”.

Energy-saving heater

Energy-saving heater

Dometic CH combo heaters make very economic use of energy. Instead of keeping the heater on all day, simply set the time for how long you want your water to be warm. And there's no need to heat the cabin air to get warm water either. Unlike other combo heater systems available on the market, the Dometic CH heats water independently of the cabin heating. Save energy and money while enhancing the comfort of your RV!
