Truma Combi heaters are perfect for use in motorhomes, campervans & caravans, offering both water heating and blown-air space heating in a single compact unit. Available in either LPG/Electric or Diesel/Electric fuel options and in different power outputs to suit the size of your vehicle's living space. We recommend the 4kW models for SWB/LWB campervans and small motorhomes or caravans, and the 6kW models for larger vehicles, however, the heating unit is the same size in all cases and power outputs can be adjusted, so you can reduce the heat output to suit.
