HOW MUCH HEAT
DO YOU NEED?
When choosing a diesel heater, it is essential to consider how much heat output you need. The required heat output depends on the size of your vehicle or vessel, as well as the effectiveness of the thermal insulation that you have. The most popular variants come in 6,800 BTU (2KW) and 13,600 BTU (4KW).
A 2KW diesel heater is more than enough in a small-to-medium size vehicle, like the 144-inch or 170-inch Sprinter. In this case, a 2KW diesel air heater like the Webasto Air Top 2000 STC is ideal.
For a larger vehicle with less insulation, a 6KW or even 8KW heater might be a better choice. Not only will it heat up your cabin faster, but a combined 6KW diesel air heater 12V like the Dual Top ST 6, or 8KW like the Dual Top ST 8, will also heat up your water.
