- Gas is already available (I have two bottles on board). Diesel would require an extra tank and another thing to carry as I don’t normally carry diesel and my genset is petrol although my car is diesel.
- Gas doesn’t require a pump so no chance of clicking sounds from the pump
- Gas doesn’t tend to have to ramp up as much as diesel. The diesel systems I looked at get more noisy at higher output. Gas tends to be the same with the exception of the fan speed.
- no smell or smoke
- don’t need to worry about water contamination or old fuel.
Although more expensive than diesel I think it’s worth it.
I'm going the new eco vario heat in our van soon for the same reason above..
We had the dometic diesel heater in last van for 10 years to keep the family happy to go free camping in winter all the time. It worked great except a few things.
Hated the clicking sound of the pump, I removed it and enclosed it in some thick insulation and remounted it, this made it a lot quieter but still could hear it in the dead of night which annoyed me more than the wife.
It used to sound like a jet engine one start up and had a few funny looks from other campers as the van was taxing down the run way lol.
I ended up fitting another exhaust muffler to the air intake side as at the time dometic had not imported intake silencer. This made it a lot better.
Had to always clean out old diesel and the end of winter and flush new stuff through at the start of next winter.
Service kit cost over $400 couple several years ago and was probably due again real soon but van was sold.
It was good for the time we had it and gas systems were not around at the time here.
But now, it's going to be the new Truma eco vario heat all the way for the benefits as mentioned above.
