    Why is my newish boiler useless at providing warm water?

    About 5 year ago, I had a new central heating system (radiators) installed to replace my old warm air underfloor system. The warm air side of the new system is okay but we cannot get any hot water without running a bucketfull of cold water first. This means having to wash your hands in cold...

    How thermal store boiler works?

    How a thermal store boiler works! I’ve got an old thermal store boiler and I’m trying to work out how it works.

    Does combi boiler need an external pump or not?

    My conventional boiler needs to be replaced. One engineer suggested combi with an external pump because water pressure in my flat is low, the other said there's no need for a pump. He even said that if the pump would have a detrimental effect on the boiler. Who is right?
