Potential Domestic Unvented Hot Water Cylinder Issue.

mapj1:

Do they drain it in winter ? A lot of scout sites have toilet/washroom blocks that are little more than unheated sheds that protect little more than the embarrassment of the user,  and can be cleaned by hosepipe at the end of the day during the muddy season.  Frozen pipes  have almost disappeared off the RADAR of the  modern centrally heated house, but in such case it is common if provision is not made to drain down at the end of season.

The other hazard, perhaps less so on an adult campsite is fiddly fingers doing silly things and turning the power off while someone else is using it, or in the case of the gas ones, shutting the valves on the cylinders as a practical joke.


I'd expect some sort of overpressure feature on the tank or plumbing, a deliberate weak link if you will, and in the demos of exploding tanks, such safety devices are bypassed.

I believe that the system is used all year round, as one couple lives full time in a caravan. These people are gormless (there's an old term) and have a nearly overflowing cess pool sunk into the lawn of a holiday let home. I attended to estimate for a cess pool pump system.


Also,  the highly educated man who looked over my shoulder and gave me advice about a faulty immersion heater of the unvented system, had not turned up the thermostat for the one remaining good immersion heater thus that is why the water would not get hot.
