in THE MAIN WALL
I came across Homart brand baseboard today. It differs from regular baseboard in that it is not convective. Anyone have experience with this product? How do you determine how large an area it will service?

    Is this baseboard

    made of cast-iron?

    Flat 10\" high x 2\" thick steel?

    Made for Sears in the 50's +/- by Trantor. My oldest son has a Sears house full of it and a Homart boiler to boot. If you take it off the wall the back has channels that run the length of it. A 1/2" insulation backing of aluminum foil and glass wool is against the wall. It works great and is easy to work with. I will ask him for the manuals and see if they give a BTU output. My gut feeling is it is about the same as standard baseboard, but don't put the couch in front of the heater. ;) Art

    yep, this is the stuff.

    I think the front panel is steel. The homeowner wants to paint it--do you have any suggestions. Maybe you might want to forward a copy of the specs to Dan.

    Went through the Homart

    booklet and it didn't give any heat output specs. What little design info is in it, it sort of says, cover all outside walls, and use a thermostat. OK?? The panels are 2', 4', 6', & 8' long in his house and cover at least 2/3 of all outside wall lenght. I thought of an alternative source for data. HydroAire/Rittling has a Div. called "Panel Radiator" and they make a flat panel radiator, no fins, just flat. The PR-4 has a little over 10" of active panel height, like the Hobart at 10.5". It's output ratings are 190*F=655 btuh, 180*=588, 170*=521, 160*=454. I don't have a scanner or I'd post some pix of the Hobart book. My son and his wife learned that you have to leave some of the panel open to the room the first winter in the house. Now the outside walls have only open bookshelves. The panels are all stamped steel, welded and finished. Trantor is still in the HX business making plate heat exchangers. The panels my son has are painted with just plain old interior house paint by the previous owner and seem just fine. I think your customer could finish them any way they want with a paint that won't discolor at 180*F. Well I hope this helps.

    Dan, would you like a photo copy? Art

    Insulation

    Installed they are almost 2" thick but in back there is almost 1 1/2" of open area for insulation. The original "insulation" is little more than foil with paper backing, not much R value. Brian and I did some looking at his system and some panels that were off the wall and the question of sizing came up. What the installation guide says is, "Sears has done the work for you". The houses were KITS, pre-engineered, with plans and options, and all the heating equipment was included, sized and ready to go. His book is dated 1957. :) Art
