hello,
I've just had a new boiler installed (Worcester Greenstart 42CDi) and changed all my rads (x 13). On each of the rads is a Pegler Ltd Bulldog TVR. When the setting on the TVRs are below '3' no heat gets to the rads. When the setting is '3' and above the heat gets through.
Is this because of crap TVRs or could it be something else?
Thanks
