im trying to solve an annoying problem with the central heating!
basically all the ground floor heater are cold and all the upstairs ones are nice and hot. whats going on??
this has only happened sice the other day, after i bled one of the upstairs radiators as it wasnt getting hot! now all upstairs are hot and non of the ground floor ones will get hot.
ive tried bleeding the ground floor rads and all im getting is cold water coming out, im getting hot water out of some but cant understand why the rads aint getting hot was all ok until i bled the upstairs rad
