Hello,i have a myson orion boiler. we had an extension and the boiler had to be moved a few feet. before this we had hot water,and heating was controlled by the timer. Now i can only get hot water if i put the heating on,by the thermostat. i have got some advice off a plumber,he said something to do with electrics and that it needs to have a switch over. i dont have a maual. Please can you help as its costing me a fortune. i do have an electrican friend,but he asked for a manual.

Hi, I have a myson orion boiler in my flat. Someone came around this morning to service the boiler but I found out in the end (after he claimed to have serviced it and everything was working fine) that he was at the wrong address. Tonight I turned the boiler on only to find out that my heating is no longer working and I have ran out of hot water. Please can you help with this?

the problem is with the zone valve, it's external from the boiler, usually near the pump
