Millivolt Ceramic Heaters

The Sterling RSM Series heats like the sun by transferring radiant heat energy directly into the area to be heated and creating a warm comfort zone at the floor level. This extremely efficient method of heating can result in fuel savings of between 30% and 50% when compared to forced air convection heating. It is also ideal for the replacement of existing millivolt standing pilot ceramic heaters and does not require external electrical power.
