Caravan Hot water system

Hi Ian,
Have absolutely no idea about caravan hot water systems, however, if it's anything like a domestic unit it probably has a flame failure cutout of some sort. A very common method is through a thermocouple device, which sits in the flame and as long as there is heat, it holds the main valve open. These things do tend to fail after a while from continuously being exposed to the gas flame.

You can recognise the thermocouple - it's the little bulb thingy that usually sits next to and in the pilot flame and has a small diameter copper tube going back to the gas valve. They are usually easy to replace and not too expensive.

Hope that helps mate
Cheers
Gerry

Hi Ian

It could be several things wrong with the system,
get it fixed by a Licensed Person, these DIY jobs can end up
costing you a fortune, if you play around with Gas Appliances,
I have seen the results of people trying to fix Gas Heaters, and
blowing them selves up and there property,
The Insurance companies will not accept claims, if they find out, a
Unlicensed person has attempted to fix it.
Just a bit of advice from a Plumber.
