I lived all my life with forced air heating and cooling, but my house now has steam radiators. They perform ok, I suppose, but I know from trying that just letting the convection cause the airflow leaves them very inefficient.
With a small 6 inch fan blowing at low speed on a radiator, the room temperature will go up 5-10 degrees F.
I would prefer not to have to run power and fans to every rad in the house. I was wondering what the options were for fans to improve the radiators performance.
Standard round fans are the wrong shape, and only target a small portion of the radiator surface.
I would love something that could draw power from the heat difference, since all it needs is low speed fans to move air better than convection does.
