I have a problem with a recently installed combi boiler, one of the raidiators ( upright 1800mm x 600mm) is only hot half way up. It is the furthest rad from the boiler, would I require a pump?
no check the pressure on the gauge it should be 1one and a half bar when cold.bleed rad through nipple on top of rad.check pressure again top up if needed then run ch.it will be ok.
