I have decided to try to resolve the operational problems on this thread in order to avoid confusion and the need for repetition.
Having replaced the heater element in the HW cylinder there are a couple of issues. Firstly, though the replacement element is a 14" 3kw, ie exactly the same as the one it replaced, it gives rather less hot water. I have checked the thermostat which is similarly set to 60ºc. There is one physical difference though, the new element has quite a bit less tubing than the old. Would this account for any difference in heating performance?
Secondly, an airlock has occurred in the section of pipe that supplies the kitchen. The supply to the bath and basin is perfectly acceptable. The tapping on the cylinder for the HW is on the side, not out of the top with the vent pipe. A 22mm tee fitting is connected to the cylinder for the HW, one side going to the bathroom, the other to the kitchen. I have tried running water out of the cylinder so the water level falls below that of the HW connection and then trying to fill from the cold supply on the mixer tap in the kitchen (blocking the spout).
Any suggestions, please, would once again be very welcome. Cheers.
