I didn't fit a heater when I did my conversion to keep cost s down and I've got my Chinese diesel heater also But been looking at them again Where have you fitted them and which one I see three options at moment https://www.t7design.co.uk/2-2kw-micro-heater-12v-879-cc4-d35.html This is cheapest ,100mm outlet ,and small https://www.t7design.co.uk/4-3kw-compact-evo1-heater-1-x-100mm-12v-0c1-29b-66a.html This ones bigger and 100mm outlet but more kw https://www.t7design.co.uk/6-6kw-sahara-heater-12v-6-6kw-sahara-heater-12v.html This one s the most money ,most kw ,and slightly bigger but multiple outlets
For perspective I have a 5kw Webasto in my 60ft boat - it heats 5 double radiators, a towel rail, the hot water and it's too powerful. 1.7kw eber in van is also too powerful. Get the smallest one you can find.
My diesel heaters a 2kw and while parked does get the bus very toastie But it's not so good while moving which makes me think more kw would be better
I know you are using your heater when driving so its different but my experience is that any heater with a fan drags your battery down fast if not hooked up, if you are hooked up you can use a silent fan heater, I was always worried about the fan heater falling over even though it had a tilt safety device but I see now you can get these small ones that actually fit in the plug socket, I have never even seen or used one but if they are as good as they say I might give one a go
The Chinese heaters are good when parked up can easily manage a few nights (uses a lot of amps to start up but once running use next to nothing ) without hookup
I fitted one of those on my T4 and had no leisure battery it never ran the battery down once after using it all night they're very battery friendly.
Maybe you need to fix the draughts then? I remember my Westy was freezing until I got a new sliding door seal that didn't have the bottom section missing - what a difference!
I think either of the 3 will work well it's where people have fitted them I think above the under belly rad pack is a good place but it's a bit of a pain to drop the rad pack of but not impossible Or fit it further forward
As you’ve mentioned I think most are fitted ahead of the rad pack, the 4.3kw one can be fitted within the front pedal pan - but does need some creativity/braketry and trimming of the handbrake bracket to get it to fit, (mine is RHD), I’ve fitted mine here…for when I might get it finished 1 day!
Where yours is was my first thought all though I am LHD the bracketry bit won't be a problem as I have a good supply of Ali angle/plate/sheet I'd like it above the rad pack it's nice and out the way well enclosed just don't fancy taking the rad pack off
Not to worry I ll come the weekend after 90% sure I am dropping the rad pack off and putting it up there
