I have added a few new rads to my home heating system and 3 of them don't get hot. These 3 rads have new mono type valves (which means the flow and return are together connecting to one side of the rad).
Both flow and return pipes are hot going into the valve, but it seems the water just goes in the flow pipe and out the retrurn pipe without actually heating the rad.
Could it be that the shop forgot to give me a short piece of plastic tube which forces the hot water some distance inside the rad? And without this tube the hot water doesnt get inside the rad? Because I remember fitting similar valves before, but they came with a short piece of tube, about 10 cm long.
Thanks.
