An electric boiler, along with a radiant in-floor tubing system, has become one of the most popular heating systems for residential and commercial applications. An electric boiler heats your home by heating water that circulates through tubing installed in the floor or in hot-water baseboard heaters. An electric boiler can be zoned to regulate the temperature in different areas of a building. An electric boiler can meet the needs of most commercial and residential applications. If a boiler system has an automatic fossil fuel backup heat source or if in-floor tubing is imbedded in sand or concrete to store heat, it can qualify for the dual fuel electric rate.
