Caravan heating options

Effective but dangerous in a closed space. You might go to sleep and not wake up again.

Gas heaters produce carbon monoxide which is poisonous. If they are unventilated and unflued, such as the model you propose, the Carbon monoxide can build up in your closed environment. First you go to sleep and then as you continue breathing in your slumber it poisons you.

If you must do it, provide adequate ventilation - lots of it.

As Frank has mentioned, the CO is the problem. Even if you use it in the van it is just plain dangerous anyway re, radiant heat and risk of fire. If you survive that, then the CO will still be present and build up and even if awake it will make you very unwell as it poisons your system. You may even fall asleep and it continues to gas you. Although heavier than air as such, the convection air currents will deliver the CO right to where you are. Not an option in a van.

If you intend to plug into power why not a small electric fan heater. We find it very effective in a van. We have a diesel heater when not on power.

12 volt electric blankets..

Carbon monoxide (C0) produced by burning LPG is heavier than air and it will build up at lower levels. It displaces oxygen in the air you breathe, and simply suffocates you. Nasty indeed. You say that you will run the heater for a few hours, then turn it off and go to bed. Bed is normally lower than your normal sitting head level, and you could well be laying down into a CO rich atmosphere. Un-flued heaters are banned in households because of the CO problems, even though the gas is different, but to use an un-flued heater in an enclosed space such as a tent or a caravan is deadly.

You could always buy an All-in-one diesel heater for $200-300 and then use the components for a permanent install later. John McK has some great YouTube videos on all aspects of diesel heaters,
see here.

We use a very small in height oil column radiator heater on 240V. Very effective.

My understanding is that CO is slightly lighter than air, not heavier as mentioned by a few people.
Important if you mount a CO detector.

Sit around a camp fire then go to bed after you put it out. If it's too cold wear thermal clothing underneath.

OK, I get the CO2 thing.

Better to be safe than sorry and survive the journey.

A couple of extra blankets and a bottle of Stones Green Ginger (or equivalent) have been added to the list.

Lucky for us the forecast is for chilly overnight but not extreme cold.

After a bit of research I think a Webasto diesel heater will be the go for us.

Hope to be ready for next trip
