Does adding a radiator cover obstruct heat flow?
In our experience MDF covers do not create any additional heat loss/output problems as MDF is very stable and does not absorb heat. The heat is pushed out in to the room (rather than just going straight up from the radiator). You will see that all designs have a large bottom vent (inlet) and another slightly smaller top vent (outlet) – this means that the cool air is pulled in through the bottom and convected up and out the top. As we do not restrict this convection process in the designs the heat output is maintained as the radiator has the same free flow of “air” passing it just as if it were an uncovered radiator. In addition to the top and bottom vent all our grille options have a minimum 50% free airflow, in other words the amount of “holes” in a grille by mm2 area is always greater than the MDF area in mm2. The same principle applies to the covering of thermostatic valves. Most customers choose to cover their valves with their radiator cover rather than leaving them exposed. As a
