Morgan Posted March 11, 2022 Share Posted March 11, 2022 I'll try again. Does anyone know if Gas Central Heating is safe to run if the water supply is cut off at the mains? Thanks Quote Link to comment Share on other sites More sharing options...
kila Posted March 11, 2022 Share Posted March 11, 2022 Not qualified in the matter but I do have to occasionally top up my central heating to keep the pressure at a good level. So from that, I'd guess it's absolutely fine as the fresh water supply is only needed to top it up rather than being actively drawn from.

We couldn't find a definitive answer on Google. Quote Link to comment Share on other sites More sharing options...

Don Dan Posted March 11, 2022 Share Posted March 11, 2022 Is it a sealed system or an open vented system? Quote Link to comment Share on other sites More sharing options...

Don Dan Posted March 11, 2022 Share Posted March 11, 2022 The above system is fed by a feed and expansion tank (cistern) usually in the attic but certainly at the highest point of the system. The tank has a ball cock which keeps the system topped up with water automaticity. The above system has no Feed and expansion tank and is sealed to the atmosphere. Water top up is manual via a filling loop connected to the mains water supply. It Will have a pressure gauge that will register 1 bar pressure under normal working conditions. Some are fitted with pressure switches or flow switches which will cut the power and prevent the boiler from running. Quote Link to comment Share on other sites More sharing options...

I’m pretty certain now that it’s the top diagram that you have sent me. The water was cut last Sunday afternoon and, to date, we have heard of no problem. It was a concern because we are here (in France) and the house is there (in Edinburgh). I very much appreciate your answers, thanks a lot.

The house in Edinburgh has been empty since the beginning of November. It's now up for sale. The Solicitors turned the water off without realising that the heating was still on a timer. We have just been a wee bit concerned that all was ok. So far, so good though. Thanks for your reply. Quote Link to comment Share on other sites More sharing options...
