    I was tidying up the boiler pipework on a bungalow I bought and plan to move into. Being a cheapskate, I considered keeping the Heat Group magnetic filter. It was like the old Magnacleans with offset plastic tails and I knew it would be messy and fiddly to fit, but although it seemed a bit...

    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.
