Heat Loss/Convector Question

in THE MAIN WALL
Hi, I'm trying to do a heat loss for a room that is somewhat cold in the winter. If I've done it correctly, the Slant/Fin Heat Loss Express program tells me that I have 6,410 BTU/hr heat loss in the room. Now I need to find out the output rating for the finned/tube convector that is in that room. It is a 4 foot long unit. It is stamped with the name Tuttle & Bailey, and it looks like there are three-pipes surrounded by fins, and a tall bleed valve poking up the side. Also, the entire convector was retrofitted during a remodeling project so it no longer has the same characteristics as originally installed. During the remodel, it was fully recessed into the wall and cut down by about 3-4 inches, which reduced the cavity of air above the fins a bit. The metal cover/housing was removed, and it is now housed inside an insulated wood frame with a metal grille. What would this have done to the output rating? Also, do you think that lining the box with reflective bubble foil would affect the output rating? Thanks, Dan

    I'm not sure what the ratting on your existing convector is, but at 3/4" feed to the convector you can expect 600BTU per linear foot base on a 180* average water temp with a 20* drop. By putting it in a recessed wall, I would think that you are killing the air draft that is created as the warm air rises. I think the best thing for you to do is find a Pro in your area that can look at what you have and make a recommendation as to what's best.
