I saw an interesting device at the Caravan show this weekend, basically a simple water heater made from a flat coil of pipe that you'd put over your campfire or whatever, gravity fed with water and almost "instant" hot water out the other end, while still being able to put your pan on the fire to cook. I think the main market was rural africa..... www.jompy.co.uk. ....but its got me thinking - has anyone seen or heard of a heat exchanger based water heater utilising vehicle engine/exhaust heat ? 

saw that at the wekend too looked quite good
yes you can get engine powered water heaters they are used in the welfare vans on roadworks etc and outside workers vans, some are for handwashing and some are for coffee etc
eberspacher is one make i think , powered form the heater hoses, a while back there was one for sale on here possibly scott110 had it

Thats a really good idea eh!!!!!  its been about for a few years now, i've been looking for a decent braai now for ages nobody seems to make them,

Brilliant!! this is a very good education.....

 

Google Calorifier.
s/s tank with a coil of which your engine coolant loop runs, can also come with an immersion heater element.
Webasto also do a water heater which runs off the diesel, a bit like a combi boiler.

Hi,

Have a look for "arrolman" posts. I'm sure he was selling one a while ago.
