Yes. I initially ran 3KW but all the connections got hot. I thought about getting a 16 amp socket wired in professionally to the house electrics board but ended up getting a bespoke 2KW which I have run since before COVID.
How did you ruin your tank?
Mine has been fine.
But I don't run it for 'hot' like you would get from a diesel heater - just 'warm'.
So rarely above 30 degrees in the tank.

If the vaporizer is clogged, your van wont be able to go through a regeneration cycle and therefore will clog up. (The vaporizer injects the fuel to burn off the soot when going through a ‘regen’ cycle; google it, it’s a semi common issue on Customs once they get to a certain age/use)
You’ll also have an idea of whether it’s failing to ‘regen’ by checking the oil quality.

15 metres of 1/2 on a reel, no problem
15 metres of 3/4 I haven’t found a solution to store it.

I done it years ago and it works, heats the water too hot on long journeys but short journeys is fine. Only downside is in the winter the heat for cab heater isn't as warm unless you fit something to half heat the wfp tank and the cab heater.

It’s 5kw output but there are various types. I have no experience with heat pumps and wondered if anyone has tried or whether something like this could be a viable option. Not quite sure if it would make the water hot enough?

10 metres for me. I use 1.25"/30mm. Which can be gravity or pump fed depending which tank I draw from.
Good mix of volume and not too bulky.

Its been some time since I've posted so I'm not sure if this has been discussed but is anyone using or thought of using a heat pump water heater to heat water? Would a heat pump for a small swimming pool be enough to heat the water in the van? Could it be a possible efficient way of heating the water, maybe even along with an immersion heater to get the water warm enough?
Tell us more. What's the wattage?
I used my immersion for the first time this year today. Mainly for supple hoses and ease of use rather than 'hot' water.
