Dometic TwinBoost 6000 Gas Combi Heater
With 6000 W of cabin heating and a fast-heating 10 litre water tank, the Dometic TwinBoost 6000 keeps caravans, motorhomes and campervans warm and supplied with hot water all year. Rather than heating water indirectly like a conventional combi, its twin-chamber system runs separate air and water circuits for quicker, more efficient results, and it lets you heat water in summer without warming the cabin.
