covers

I was wondering if radiator covers made from wood (with metal grate opening in the front only) hurt dispersing the heat? I have covers where the top is wood, the back is open, and the front has a metal grate . Should I remove them? should I do anything to them to make them better? I just want to make sure I am not hindering the heat (it is a one pipe steam system). Thanks

    They most likely greatly reduce output.
    There are designs which act similar to a convector and create a draft through the radiator which increase output but it's not a simple box with an open front and back.

    I also feel all covers reduce the amount of radiation the radiator provides regardless of whether or not overall heat output is increased. I prefer radiation over convection my self.

    I have been considering doing something along the "deduct 10%" design for my son's room to increase the radiators output.

    @ChrisJ , I retrofitted a couple of my original covers and the difference was immediate. I can still close the tops in summer. I'd also suggest some relflective behind the rad and painting them in a matte colour.

    My dreams, are to paint all of the radiators flat black. :)

    I had also looked into buying glass mirrors to put behind them. Sadly, cost shut that idea down real fast.

    I've wondered how much the "deduct X %" would be by adding a fan to the radiator to try and get more output.

    My covers fall into the "classic radiator cover" example. Has anyone had any experience with creating holes in the top lid? I'm sure a screwdriver would work but I was wondering if there is a way to "nicely" make hole punches in the sheet metal (taking the lid off and making the holes). Need to keep wife happy but wouldn't mind increasing efficiency :)

    A step drill might be a good choice.
