Using electricity for heating can be very price competitive compared to heating with liquid propane (LP). Off Peak electric rates or time of use rates (TOU) offered by electric utilities can provide substantial savings over boilers heated with propane and be competitive with natural gas. The installation costs for natural gas or propane boilers are much higher than the total installation costs of electric boilers. This is due to the higher purchase prices of gas boilers and the extra costs that are incurred for safety venting. Compare total installation costs before making a final purchasing decision.
