u have to get a 12v of ebay,  in theory it would work, i looked at doing it a few months ago, but couldnt be bothered,   some say that you should heat the water after its been in the pump, but i am not sure on this

I've done it on my static tank and transfer warm water to my truck on very cold mornings.  I posted a thread on it a while back now.

i was wondering if i could plumb the heater of my van through a coil in tank to heat the water ?

[daz1977]

it can be done, its just like an immersion tank in a house, but for safety you will have to have warm water and not hot, unless u want to put a metal tank in ur van

ur just have to drill a small hole in side of tank, put immersion in, seal it up properly and switch it on,  the heat you will get off a 12v, will take a while to get the water up to temp i think

Why does it cost £2000 ?

[ccmids]

if you look on varitech site they are called heatwave thermo and they are £2.295.00 each.  varitech systems
type in your pc       varitech catalogue 2009-3

[daz1977]

u could probably do it ur self for less than 100

[ccmids]

no jokes please , how

[Spruce]

You will need to couple this eberspacher to a stainless steel heat exchanger and pump the cold water through it and then on out to the brush.

There is a thread by someone who has done this on this forum and he has a picture of his conversion. Not a Varitech unit, but then nowhere near their price either.

what size tank do you have,  as this will determine what u need and how long it will take to warm up

if it was me, i would drill a hole in the side of the tank  connect immersion,  wire up to battery and switch it on,  then get battery wired up to alt on van so that it is on charge,  or have immersion wired to a battery on its own

depending on ur tank size, depends on how many immersions u need

in theroy its the same as a ele towel rail,  but much bigger

something like this

O sent a question to the bloke who sells these 12v one a while ago now and he said no way would it heat the amount of water wea re talking about. I was asking about 650 litres at the time.

[idealrob]

I know its changing the thread a bit, but does it heat the water to 70 degrees, and apart from the obvious, quicker , better for cleaning etc, is it worth the extra ?

its a case of finding the one that does, if he has to put 4 in to do what is what i would do if i was on a budget,

for all we know he might just have a 250 tank, will work,, just the time it will take, 

i would put 4  of the 700 watt ones in and run them of a separate battery

 

[daz1977]

if you want a cheaper option,  insualte the tank, and fill with hot water every morning from the house, good insulation should last most of the day
