I swapped the wires and it certainly made a big improvement. I Noticed when I turn the thermostat theres only 1 degree between on and off. Before it was about 3 degrees. Thanks for the help. Alex

The thermostat is in the hall , the nearest rad is in the hall on the opposite wall about 2 metres away. it hasnt got a TRV on it in case you ask. The top 2 terminals on the boiler are not marked individually, only says Room Stat. Its wired as per diagram . Boiler top term 1 goes to...

Hi, Its wired using 4 core cable direct to Thermostat , its only about 3 metres away. I tested the wiring with a DMM by disconnecting and shorting out each wire to earth wire and all tested ok . I have double checked the connections and the Neutral is connected from boiler Neutral to Stat...

Had a new boiler fitted in summer. No problems with it except that when thermostat clicks on, the boiler fires and heats the house. when thermostat reaches correct temp it turns off boiler. the problem is the house gets really cold before stat clicks on again and boiler refires. House is...

this is a combi so no tanks,,, the pump does run when the hot water is used as i listened to it ,, but it only makes a rattling sound when it switches to heating,, if i then turn on a hot tap is goes quiet,, i use a large wooden handled screwdriver to listen to where the sound comes from and it...

would that cause a mettalic knocking, sounds like a lump of metal in pump banging about,, what i cant understand is that its silent when running hot water,,,, 2 years ago the boiler was moved and flushed out and it has a descaler in the water system
