How to Refinish a Cast Iron Gas Heater

Cast-iron gas heaters are designed to mimic traditional cast-iron wood heaters. They are attractive and give an authentic feel to a room, but they burn cleaner and require less maintenance. Over time, even these cast-iron heaters can need refinishing. You can do this yourself using the appropriate high-temperature paint. These are available in many colors to suit your decor. You can even finish with a shiny topcoat to give the cast iron gas heater a porcelain-style finish.
