Improving Radiator Efficiency: Hang on Fins and Heat Reflectors
My parents have a big old house with steam radiators. Brick walls, insulated in the 1970s with blown cellulose. I am not handy or ambitious when it comes to home projects.
1.) One source online made a comment about Radiator Fins that could be hung on an old radiator to add surface area. Has anyone heard of such a product? Where would I get it?
2.) Do radiator heat reflectors work? Any reason I couldn't just use that foam insulation panels with foil lining? Or would the heat make them melt or outgass or something?
