The gas air and water heater is a popular choice for heating both water and living spaces in your campervan, motorhome or caravan. Able to operate on either 220V/110V electric mains voltage or on LPG, the combi heater provides hot water and a warm campervan, motorhome, or caravan, whether on a camping site or in the wild. You can even use both electric and gas energy sources in unison for rapid heating.
