my dad has moved into a flat he has 7 radiators with just the
decorating heads on
in the block Nobody has trvs due to the builder going bust
and cant locate him
so how can i get replacment heads or do i need to change the whole valve?
i have taken a photo on my phone and will try to down...
the c/h light stays on does not flicker i have changed nothing all i did was drain down swop a radiator for a towel rail fill the system up bleed the rads and now nothing!
when i try to light the boiler the green light comes on the heating light comes on the burner liht comes on and then after about 30 seconds the burner goes out but pump runs on.
air vent has cap off and splaterings of dirty water stains all over the casing.
