Removing fins from baseboard heater to reduce heat inside room

Posted by pornstar40 (My Page) on

I just purchased a home built in the 1950's which has baseboard "Slant fin" heat. I love how well this type of heat keeps the house at a very constant comfortable temperature with the exception of one smaller room; it's just too hot.

Does removing some of the fins from the copper piping reduce the amount of heat inside each room? I was told this is the case by someone who may or may not actually know what he's doing and wanted to confirm before doing so.

Thanks to anyone who can offer some advice!

Suggest you also post this on the HVAC board.

"Does removing some of the fins from the copper piping reduce the amount of heat inside each room?"

The fins increase the radiant area, so in theory the answer is yes.
Not a method I would choose.

Yes, you can do that. With fins, they produce 600 BTU per foot. Without ??? Maybe 100 ?? not really sure.

Why not turn down the aquastat? If it's 160/180, turn it down to 150/170 or 140/160

I don't know if that's the right thing to do, but it would work. It's preferred to close the damper, which cuts the air circulation across the fins.

I suppose you could also remove the cover, then cover the fins with a single layer of foil-covered insulation, then reinstall the cover. The foil insulation I'm thinking about is the stuff that comes in rolls and is used to wrap exhaust fan ducts.

It would work, however you dont know haw many to remove. Find another method, such as the idea of covering them. This will allow "adjustments".
I think I would try regular aluminum foil. Dont use anything remotely combustable.

Lowering the aquastat settings would have an immediate effect and save fuel, but I forgot that I had foiled over some of my own baseboard in the garage and it works well at reducing the output and allows you to undo it at a future date.
