Hi Pete
My experience with catalytic heaters is some years old now. I bought one to use in my VW Westphalia, but the big problem with these heaters is… “Condensation”. I suppose they’re much like paraffin heaters in that respect – for ‘x’ amount of gas, there is ‘y’ amount of moisture produced. They’re probably fine for use when tent camping, but less satisfactory in caravans/motorhomes, where condensation is a big enemy.
So I got rid of mine. I recommend you continue to ask around to obtain a consensus of up-to-date opinion. As I say, my experience of them is some years old now, though I can’t see how they can have changed the chemistry!
They are available on eBay shipped from the US for £265… https://tinyurl.com/uhhjtzk
They’re also available from Amazon.uk for £337… https://tinyurl.com/tqxzskt
Let us know how you get on with this Pete. It would be nice to know if these heaters are viable in our m/homes.
