    Worcester Bosch Greenstar Regular Boiler - Always ON

    Morning all, I've noticed very recently that our Worcester Bosch Boiler is constantly ON and making a fair bit of noise.

    One pipe system condensing boiler.

    Would a one pipe system work efficiently on a condensing boiler as the return type would likely be below 54c all the time. So the boiler would run in condensing mode. Alot of condensing boilers don't run in condensing mode.

    Ferolli boiler leaking water from gas valve

    I have a ferolli HE31C and it has developed a water leak that appears to be from a porous casing in the gas valve. I can not see where water even enters the gas valve as I presume the gas goes in the bottom and out of the top of the valve. To check this out I dried it off and put some sealant...
