    radiator decorative covers

    I just completed a boiler install for a friend. She insists on leaving some decorative covers on a few of her radiators. On some others she has placed shelves with knik-knaks for decoration.
    My question is, is this killing the heating efficiency of the system. I tell her it is but dont't have any reference to make a compelling argument.
    A normal boiler install for me would be a 50k lbs steam/hr unit. A Laars 125k btu is a little out of my league.
    Input on this subject from a residential professional would be much appreciated.

    The newsletter is helpful. The particular covers she is using are the worst case according to the diagrams (add 30%). If a cover open in front but solid on top requires 30% more radiation with a 3" gap between radiator and top, it would seem that a cover sitting directly on the radiator (shelves) would be much worse.


    Is this restricted heat radiating through the outside wall?

    Look at the second rad cover article

    it has the math figured backwards to show the effect of a cover on the existing radiator. In the case of her covers it would reduce the rad's output 33%.
