Does painting my radiator effect how well it works?
If I paint my radiators, will that effect their efficiency? Will they still be able to heat my house?
Don’t worry – slapping a fresh coat of paint on your radiators won’t make a huge difference. The type of paint you use on your radiator will effect it’s effectiveness – specifically, the last coat of paint that you use. Metallic paint can reduce your radiator’s ability to transfer heat via radiation (a polished metal surface does not radiate well), so non-metallic paint doesn’t interfere. However, only a third of the heat produced by your radiator happens through radiation – the other 2/3rds is from convection (heating the air around them), so any difference in performance may not be significant.
