    Intended Alterations

    Thanks S123, Had a suspicion that 1.5 might need to be 2.5 and thanks for taking the time to 1.) Upload the image to the site 2.) Have a look and advise. On looking it seems the fused spur I have in my box of tricks is a 13 amp, can I assume it will be OK to use for my light as long as I...

    Worcester Highflow 4.5 boiler

    My Worcester Highflow 4.5 boiler is acting up and I wonder if anyone can advise me. Today the hot water is working but the heating has gone off, the pilot light is still lit, and the boiler kicks in fine for heating the hot water. I've checked a couple of my radiators and they don't have...
