    I have some fernox HP-5 heat transfer fluid my mate gave me, would it be ok to use in my wood stove central heating system - radiators, pump. Or would I be better with the regular inhibitor for central heating?

    Read HP-5.

    The product is intended for use in ground/air source heat pumps and underfloor systems. It is not diluted, so you would need a lot to fill your rads and pipes - maybe as much as 100 litres.

    You should use the regular inhibitor.

    Pretty sure you meant to say it IS diluted, rather than it's not...

    If the OP has a thermal store he could need 300L - about £500's worth

    I have 10 litres and was just going to use that in the system. Not fill the whole lot with it. 6 rads.

    It'll be entirely useless if you try to do that - it's designed to be used as-is and not diluted down, IE it needs to be used to fill the system completely or it won't be effective

    OK thanks, I'll pick up some regular inhibitor tomorrow.
