Burnham Sunrad Radiator

in THE MAIN WALL
Do these rads need to be installed inside a wall? I'm gonna be moving a lot of things around. Wondering if I could install these freestanding beneath a window sill.

    Either free standing or in a wall is fine. If recessed increase the size by 10%

    So do these radiators produce MORE heat when recessed inside a wall? Or do they need more steam/btu to heat them?

    Perhaps he means you need 10% more heat there because you have less wall insulation where the recess is....sometimes just about none.

    It's in Burnhams brochure to add 10% if recessed.

    If you have a room that has a heat loss of 15000 btus and you recess the radiation you would have to select the radiation off the chart at 15000 x 1.10 =16500

    It would be wiser to not completely recess them in outside walls and if so be sure to have some insulation between them and the outside other wise you may have issues w air vents whistling due to vacuumed forming as the system cools down . Peace and good luck clammy

    That's an excellent point. Thank you!

    I don't like the idea of recessed rads anyways. Will be pulling them out of the wall space and relocating. The steam job in this house is atrocious! It does work, but this place takes the award for shoddy workmanship.
