    Vaillant Sustain 28kw Combi Heat Input

    Could anyone tell me whether the Vaillant Sustain heat input is noted in gross or net please. I was sure it was NET but someone has said it's gross which makes no sense at all. I work all my gas rates to NET so if I'm wrong my gas rates will be way out. I've included the data badge.

    POTTERTON PROMAX 28 COMBI Boiler - Hot Water Issue

    Hello, I am seeking some advice, I have a POTTERTON PROMAX 28 COMBI Boiler and I noticed yesterday that the water around the house is no longer warming up. The heat exchanger has been changed 6 months ago, so I do not believe it is that. Does anyone have any ideas on what it could be? Thanks

This, I believe, is a blocking code that trips the burner but when/if it resets. the burner will refire without any boiler reset? If this fault code is up while in CH mode and there is a demand for HW, will the boiler...

He did not inform us that we would need a new processor because we had changed to a Combi and subsequently a valve blew. Should my builders...

    MT10RF replacement on greenstar junior24i combi mk3

    The clock timer on the Mt10rf transmitter does not work, but it can be used in day mode to get the heating on. Is Drayton LP10RF a suitable replacement? I guess the receiver from this would need to be used rather than the existing Worcester one?
