Hi, i have a thorn housewarmer boiler and cant get any central heating. The hot water is working ok and the radiators warm when that is on but when i switch the heating on via the wall stat nothing happens atall. Thanks if anyone has any ideas.
ok found it!it doesnt have the bit on the side labelled on your pic 'speed' just the main black part. how will i tell if its not working?no sound im guessing!
Sorry, on closer inspection it isnt actually a screw, it is a dial that has 3 settings, min (l) ll and max(lll). sorry for taking so long, took a pic and trying to upload it but its taking for ages!!!
