Central Heating and Hot Water not working properly together
Question on hot water and central heating not working correctly.
Standard heating system - gas boiler, timed clock switch, no room thermostat, mid position valve. Turned on heating couple of weeks ago after the summer and everything worked fine. Then heating stopped working. Covered by BGas cover so engineer called. First he said it was loose connecitons in the Mid-position valve - fixed it and it ran. Next morning didn't come on. he came back - couldn't find anything obvious - got it working and left , promising to call us after 2 days to see what was happening. Again didn't work that night or following morning. He called today and is coming again Friday. Wanted to run these symptoms past the group to see if they made sense and you could advise , so I can gently point him/BGas in the right direction - he didn't inspire confidence previously when he didn't try all options. After couple of trials I think I've figured these are the symptoms. 1. If hot water is timed to come on before heating then heating doesn't work. 2. If heating is timed to come on before hot water than heating DOES work and so does hot water. Mid-posiiton valve seems to move to all the right positions when taken off the pipe and tested using the different settings on the times i.e. CH/HW on/off etc. I've proved this last night and this morning. Since I'm not mending it myself I'm not going to get into fine details but was after guidance more than anything on whether me interpretation would be feasible. Cheers.... |
