Baseboard / Floor Furnace Questions

Brian G

Recommended Posts

I did an old house yesterday that still had functioning baseboard heaters in it, a rarity around here. Does anyone know offhand what the clearance above these things should be, for drapes, etc.? Or in front, just so I can note it for the client?

This house also had the first functional floor furnace I've seen since I was a kid. I ran it to check the output and CO. I took my digital thermometer off the grate at 185.8 and rising, for fear it would ruin it. CO never got past 8 PPM. Are they supposed to get that hot?

what was the heating source for the baseboard, were they electric or hydronic ??

They were electric, each with its own wall thermostat. Instead of temperatures, the thermostats had numbers (Off - 9).

What was the "furnace" I mean was it heating air or water and what was the fuel source ??

It was a natural gas unit, warm air via gravity as far as I could tell. It also had a wall thermostat, but a normal one.

You know Gerry, with a name like Beaumont, you should've moved down South. Try this with a thick Southern accent...Beaumont ma'am, Gerry Beaumont, at your service. [:-tophat]

Hi to all,

Brian, here ya go:

Electric baseboard convectors: all the IRC & NEC have to say on the subject is to be installed as per manufacturers instructions, but that they cannot be mounted below regular outlets. having said that I know that most manufacturers do list clearance to combustibles such as drapes (typically they call for 8" above the heaters, and if hanging in front of the unit have 3" clearance and be 1" above the floor).

As to the temp of the furnace, that does not sound particularly excesive as they do get very hot particularly on the top panels.
