    Glow Worm Compact 100PP - boiler turns off when central heating is on and hot tap then turned on - a long running saga!

    If you want a read see link below but basically it’s a reaction between the copper and the oil they put in natural gas, and it flakes off once built up https://www.heatgeek.com/black-dust-sulphidation-in-gas-lines-and-appliances/

    back to wall toilet cistern, help needed

    No as you have two different applications eg the toilet frame that’s designed to go in a wall The toilet unit is designed for a back to wall pan

    Glow Worm Compact 100PP - boiler turns off when central heating is on and hot tap then turned on - a long running saga!

    I think it’s a main pressure issue as the pilot was lit (eg nothing controls that other than flame or thermocouple etc) so I suspect hot water demand full flame and it’s struggling for gas flow so pilot gets small and boiler locks out So best to get your gas guy to inspect the gauze in the gas...
