Truma heater

Lyke Wake Man

i have a Truma heater in my van, but if I light in when it's windy the flame keeps blowing out, I think they a bad design as although they sealed so no fumes come in the van, being open under the van is the wind blowing out the flame from under the van or is the wind blowing down the flu.

Using E.H.U. isn't an option as we go off grid, also they don't get very hot electric
