Hi,
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.

I was thinking of something like this…

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?

Did the immersion heater work well for you? I fitted one before but totally ruined my tank. It was an expensive error for me and was quite costly to run. But it was so nice to have warm pipes!

Could always plumb a calorifier tank to your vehicle radiator and indirectly heat your deionised water. 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.

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.

5.5kw.!! That's heading towards ev charging requirements.

That is the output Wattage Spruce. Input is more around 1KW
