    Worcester Bosch Heatslave 26/32 Hot Water Problems

    I had a system earlier in the week that the mid position valve was so jammed up it wouldn't shift from the mid position

    Worcester Bosch Heatslave 26/32 Hot Water Problems

    Maybe been unlucky - Ive done a few and always come out in one piece. A bit like closing the door after the horse has bolted I know, but I'd fit a system filter to remove any loose debris floating round

    Worcester Bosch Heatslave 26/32 Hot Water Problems

    No, it's not meant as a lubricant, only an anti seize compound. Use Molykote 111

    Worcester Bosch Heatslave 26/32 Hot Water Problems

    If it's a 17 year old Heatslave it will be fitted with a piston type diverter valve. This will have become jammed in the down position. There is a grey actuator head fitted which has a push button release - press this and the actuator twists off. Under this you will see a pin sticking up. I...

If you dont have loctite 55...

    Stuck Riello RDB burner

    I appreciate the post is a few weeks old, but can you get the flange off the burner? If not and if it still won't budge, then I would dremel off the flange from the burner and fit a new flange

    Bunded 1000ltr plastic domestic oil tank leaking from inner to outer skin

    When I've found them to have leaked it's always in my experience been a split. The only way is to empty and take the top off and look.

    Should be flared fitting ideally. I stopped using compressions many years ago

    Sds max has died I need a new one.

    I have a Hilti and a Hitachi. The Hilti beats the Hitachi hands down in performance. Had a Bosch before which I bought second hand and was fine. You do get what you pay for.

    Grant VortexBlue Oil Boiler

    For system water it doesn't really matter. It's not going to be constantly refreshing but you keep the same water in for ever until you come to do any work on the system. Always be sure to add inhibitor. If you constantly have to keep topping up, then it may cause a problem, but if that is...

    Floorboard holesaws................

    You can put the plug back into the hole but of course firstly you need something in place to support it from underneath. Pass a short bar of wood through the hole and screw it on straddled across the hole from underneath so that the bottom of the plug has something to attach to. I usually just...

    What is the best pipe slice?

    I have a Tornado branded one which I think is a Toolstation brand. Doesn't seem to be any different to Kopex. The main thing is to remember you replace wheels when blunt and keep them well oiled and occasionally solvent clean them to get rid of dust and debris. Even the best one won't perform...

    Hot water pressure issue

    Does it stay the correct temperature if you run a hot tap slightly elsewhere to increase the demand? If so, I'd be looking at a flow switch fault

    Grant VortexBlue Oil Boiler

    I wouldn't touch Firebird with the proverbial end of the stick. Grant Blueflame all the way. If it goes wrong, everything is covered fo 10 years

    Hot water pressure issue

    It sounds like the boiler is not able to keep up with the demand being placed on it by the hot water draw off for some reason, assuming you are meaing it goes from hot to cold and remains cold until water turned off, rather than cycling between hot and cold whilst running. If it were the heat...

    Rayburn 480k mostly not firing

    They're not that complicated if you actually bother to follow the wiring and circuit diagrams

    Grant Vortex Condensing Boiler air in fuel?

    Pressure test the oil line to find your leak. I suspect it will be badly done joints (probably compression fittings without the required brass inserts in the ends of the pipes) allowing air in. Sounds like your guy is just guessing
