Calorifier

Thanks for the heads up !Got outbid..made £174...But they are £500 ISH new.So I'm going to stick with my homemade one..works perfectly well gives me 10ltrs hot water in 10 ISH minutes from the diesel hydronic heater.
 
I think a 10l one would be woefully inadequate i have a 30l horizontal surecal in the crafter, even with a lot of extra insulation the heat loss overnight from such a small quantity of water is considerable especially from the relatively large surface areas of the immersion heater boss and copper pipe work.

I have the dual 230/12v immersion and we use ours as a solar dump load which does mean free hot water for most of the year.

For the iveco I’ve bought the much cheaper but seemingly better insulated Whale water heater, mains only but again will be used as a solar dump load via the inverter
 
Yeah mine is a 30litre horizontal and agree with the heat loss. I have never added any extra insulation though, just the factory sprayed layer over the titanium tank shell. I don't think this is very thick on The SureJust tanks
 
Many years ago, I had a motorhome that had a calorifier, though by the time I got it, that didn't work.
I didn't bother fixing it, because it was of little use to me due to my pattern of use.
Calorifiers work best if you drive the vehicle for an hour or two every day, or (better) twice a day.
I tend to drive for a while, then park up for a day or two, before driving for less than an hour and parking another day or two.
My pattern of use means no hot water in the calorifier when I want it. That van had a multipoint instant hot water heater. Worked brilliantly, once I had plumbed it in.

The previous owner had fitted it, complete with the flue through the roof. Having done the hard bit, they'd not connected the gas and water.

Correct if you don't have a coolant heater fitted, if you do just turn it on for half an hour or so.

If you have a coolant heater, what powers that?

Mine had an eberspacher hydronic under the passenger side headlamp. I believe a lot of sprinters came with these for winter starting? My system is added in to that
