Hi All,
I have a strange problem that started 2 days ago. I have a Worcester Bosch Boiler and Unvented Cylinder. Been working solid for 3 years. Yesterday, there was no hot water at any outlet (tap/showers). It was just lukewarm.
The thermostat was set to call for hot water but the boiler wasnt firing. I noticed that the pipe from boiler to Cylinder was lukewarm.
I switched on heating and the boiler fired up and heating was fine at the rads.
This also led to the pipe going to cylinder to heat up (hot to touch). But the Hot water outlet at the cylinder remained lukewarm.
This didnt make sense as the coil pipe was hot but water leaving the cylinder was lukewarm.
I did some research and someone mentioned trying to reset the cylinder stat and this didnt work. I pushed the power button to power cycle the boiler and still the boiler didnt fire for hot water.
But then I switched of the power to the wiring centre for the boiler as well as the boiler. And on switching it on the boiler fired and we had hot water.
Today, we had the same problem. Hot water ran out and I had to switch off power to the wiring centre and the hot water came back.
I see the wiring centre supplies the cylinder stat and and the valves so Im assuming something is wrong there and resetting the power is temporarily forcing one of those to reset.
Any advice on what is going on here would be greatly appreciated. I have contacted my installer but currently not had a response.
Thanks
