Radiator Heat Feflectors
My parents have an oldish house with steam radiators. I read online that placing a reflective barrier behind steam radiatorsa increases their efficiency by reflecting back into the room radiant heat that would otherwise be lost to the walls.
There are products that do this and apparently they are recommended by the UK government:
What I'm wondering is, couldn't I just use those foam insulation panels with the foil coating you get at Home Depot? My one concern is that they would be too flammable. Others online recommended wrapping cardboard in foil.
I am extremely unhandy and am looking for some "low hanging fruit" in terms of energy efficiency to keep me occupied when I visit for Thanksgiving.
