bit confused about the pricing for these hot water systems saw Corwoods I think selling them for 180 quid but then I've seen heaters selling for 2K on the WCW site what's all that about?
Basically there are 2 types, diesel powered and gas powered.
Diesel ones use a webasto type heater, take diesel from the vehicle's fuel tank (so no gas bottles) and are generally easier to operate so I understand. They cost about £2,000 to £3,000 ish.
But if you're poor you have to use what is basically a camping shower that uses propane gas bottles and needs a flue to let the gases out or can only be used if bungied onto the back doors with them left open etc etc.
Still not sure about the legality/insurance issue of driving around with gas bottles connected up etc, but those who use it always have a next door neighbor who is a driving-around-with-gas-bottles-expert-who-advises-the-united-nations-on-what-is-legal or a qualified-motor-vehicle-insurance-and-gas-engineer-who-knows-everything-about-it or another person who is the highest expert in europe. In other words camping shower users want want it to be legal so it is.
Failing that, if your REALLY poor (I'm talking breadline here) then you just use cold water like me.
