Thanks for the fast and positive replies, I got on a bit of a downer after speaking to some of the caravan places, they made out like i was living in a death trap!
The stove, surround and flue are all e marked and the whole thing has been checked by a corgi registered gas inspector, so i know it's safe, i mean, i've had the caravan at 29 degrees and there is no heat build up on the surrounding walls as they're lined with fireboard.
The annoying thing, is that there's not really any legal requirement for fitting a wood burner in a caravan, it's totally different to a house where you have building regs, but in a caravan it's more of a grey area.
It was such a long labour to get fitted and has been so worth it when it's been cold!
It's nice to know some people still appreciate common sense over health and safety rules!
