  • Electric Boiler vs Gas Boiler: Pros, Cons & Running Costs

    Electric boilers have an efficiency rating of 99-, while the maximum efficiency of gas boilers is rarely more than 93%. So with a boiler that's 93% efficient, for every £1 spent on heating a property, 7p is wasted on lost energy. On the other …Learn More

  • Should I convert my boiler from gas to electric

    Mar 25, 2009 · My house's heating system is gas-fired hot water. It's a fairly efficient system, but I've been thinking of swapping the boiler out and installing an electric boiler. Here's my thinking, Electric boilers are more efficient, of course. But they give me more flexibility in the actual "power source." With natural gas, the prices fluctuate during oil crises, and there's only one source for …Learn More

  • gas vs electric boiler — Heating Help: The Wall

    A kilowatt hour of electricity (kwh) has 3,412 btu's. If a kwh costs $.25, that means you can by 4 of them for a dollar = 13,652 btu's ( 4 * 3,412). To make things simple, lets assume efficiency for the electric boiler. Based on this example, oil got us almost 3 times as much heat as electricity. You can go through a similar exercise for gas.Learn More

  • Efficiency factors in natural gas fired steam boilers

    Due to a high oxygen level in the boiler, a 1.4% loss in efficiency occurs and thermal power reduces by 0.74 Gcal/h to 52.3 Gcal/h. The economic loss is $24.4/h. Effect of radiant heat loss on boiler efficiency A steam boiler has a higher temperature than its surroundings, therefore heat losses are observed through the surface of the boiler.Learn More

    Apr 30, 2021 · Typical boiler efficiencies are 80 percent for natural gas-fired boilers, 75 percent for biomass-fired boilers, and 83 percent for coal-fired boilers. The calculation of effective electric efficiency is the CHP net electric output divided by the additional fuel the CHP system consumes over and above what would have been used by a boiler to Learn More

  • Natural Gas vs Electric Heat: How Should You Stay Warm

    Typical boiler efficiencies range from about 90% for the best solid biomass fuel boilers to close to 95% for oil- and natural gas-fired boilers, Table 3.2. The main reason for the poorer performance of biofuels is the high moisture content of the fuel, which increases flue gas losses.Learn More
