If you’re looking for an easy way to make your cast iron radiator look more appealing, paint is one option that’s both inexpensive and easy to pull off well. Painting your radiator is typically done to improve the look of the unit. What most people are unaware of is that the right kind of paint will actually alter the performance of the radiator simultaneously. So, what’s the right kind of paint? It depends on what you want to alter about the radiator’s performance. If you feel that the cast iron radiator is putting out too much heat, you should consider choosing a metallic paint. The metal flakes in the paint improves the reflectivity of the unit. In some cases, this can reduce the heat output by as much as 20%. Don’t think that painting your radiator is merely going to improve the outward appearance – it could actually improve the unit’s performance, too.
