catalytic heater

Yes, I agree with Peter.
Death can be rather permanent. Heating yourself outside the van by radiant heat, is OK with ventilation, inside the van NO.
I have installed a diesel heater to my 17' van. Exhaust is outside and warm air inside. Never to mix them is best.

I have a Coleman black cat heater, and can confirm they have the relevant scary stickers and warnings. They are not something you would trust inside a van. Reverse cycle or diesel furnace is the safe option.

Thanks all for the feedback, looks like a catalytic isn't the way to go. "She who must be obeyed" got a bit chilly recently in minus 3 deg. temps. Looks like having to wrap her up in a doona. I suggested a brisk walk before retiring "If looks could kill".
I reckon the temp. dropped another 5 deg. inside the van with that look.

Thanks again,
Terry c5.

Met a fellow at Binnaway nsw that installed a diesel heater from ebay. Some dont have an exhaust nor fuel tank so be aware but his has worked like a charm around $900. Push button start should make your wife happy

We got ours from snugger Australia for that money with the whole kit, warranty and a bloke you ring and get installation hints from - and full spare parts backup. We like ours. I did buy a webasto intake silencer for it too which makes it quieter again.
