Can anyone help as I'm baffled. Why would the boiler feed/return to the hot water cylinder be hot and the thermostat be set to 60C but no hot water output?
My experience of domestic heating systems is limited. I'm in a 10 year old house with a gas, indirect boiler system. Central Heating works fine but the hot water has started to give a problem eg whilst showering I now have to keep moving the temperature up. And now there is no hot water at all. Next to the cyclinder there is a 3 way switch for CH/HW and I've replaced the controler for this 3 times now and the last replacement was a month or so ago. It was showing a light to indicate HW is on. The cylinder boiler feed and return pipes are both red hot. I removed the switch control and the valve switch was in the correct position for HW. The pump is also working. Yet the cyclinder output pipe at top of tank is cold. Not knowing what to do I've played around turning the thermostat up and down and turned the 3 way switch from HW to HW/CH to CH to HW and run taps. And now its working: I started getting warm water and now its hot but I noticed that the power shower is still not good the original cold/hot mix setting and needs more hot. Any ideas, suggestions.
