While investigating a new motorhome, a few we looked at had the option of heaters fueled by diesel, rather than the more common LPG (or LPG and/or Electric). I've also noticed that diesel fueled heaters are quite popular with those who do their own conversions to vehicles like VW vans, Transits, etc. I also suspect they are used in HGVs, at least when then drivers are parked up and sleeping in the bunks etc. I also remember the M1 Tank having one when I did some trials in the US. It kept 'waxing up' as the tank had been fueled with 'summer' diesel and it was Jan in Michigan (ie very cold).
We didn't opt for a motorhome with one but I'm still curious about them, more from general interest. Has anyone on the group any experience on one, probably on a van or HGV? Do they have a 'real' burner or some kind of catalytic affair (if such a thing exists for diesel)? How are they vented etc? What about fuel consumption?
