So I had the acova 3 column radiator from Screwfix fitted yesterday. But I believe it has been fitted the wrong side. Instructions manual clearly states: VERY IMPORTANT: PLEASE NOTE: WHEN CONNECTING THE PIPE- WORK TO THE RADIATOR, THE WATER MUST ENTER THE RADIATOR AT THE BOTTOM CORNER DIAGONALLY OPPOSITE THE AIR VENT AND EXIT AT THE BOTTOM CORNER BELOW THE AIR VENT. The TRV has been fitted on the RIGHT side. See images. The air vent is on the TOP LEFT. When tested after fitting, the LEFT side pipe was much hotter so I believe this is the flow or intake pipe?? All the radiators in the house have TRV on right so I assumed this is the flow side though I know a TRV can be fitted on either side but better on flow side. This radiator is fully reversible so should I flip it around to follow manufacturers instruction and also connect TRV on left side???
