Downstairs Radiators not heating
Radiators may/prabably need balancing
Turn all the upstairs rads of by the lovksheild valve. Then turn each
one on by a quarter.
It is very unlikely to be a balancing issue, as they worked before and the
balancing adjustment wasn't touched. Setting all radiators to 1/4 on is far
more likely to bugger up the balancing than cure it.
