I'm involved in a project with central heating. Due to a miscalculation the apartment radiators are about 50% too large. The current system water flow is based on the assumption that the radiators are the correct size (i.e. smaller), even though they are not. Due to this the water takes longer to pass through the radiator, lowering both the return temperature and the overall surface temperature. This in turn also makes the heat output lower. What I can't wrap my head around is that a lower return temperature indicates that more heat was transferred - but how does that comply with the heating output being lowered...? What am I missing?
