  • batteries - How to calculate the heat dissipated by a

    Jul 25, 2013 · The rep told me that the important value is the difference between the "Combustion Efficiency" and the "Fuel to Output Efficiency". So in my example of a Burnham 3P-200-G boiler, the difference is 82.629% - 80.217% at the pressure, ambient temperature listed, etc., which is 2.412%.Learn More

  • How to calculate the power consumption of the electric boiler?

    Sep 08, 2019 · The electric boiler uses electric energy as the energy source, uses electric resistance or electromagnetic induction to drive the heat, and when the heat medium of the boiler heats the heat medium water to a certain parameter (temperature, pressure), the external output has the rated working medium (steam or hot water).Learn More

  • Cost of Running An Electric Boiler in The UK

    Dec 10, 2003 · Basically, all losses end up as heat, including friction, windage, core and winding. So just use the efficiency of the motor. A 100 hp motor that has an efficiency of 90% requires about 111 hp of input energy (at full load). It will deliver 100 hp to the shaft and dissipate about 11 hp (8.2kW)as heat.Learn More

    Dec 19, 2019 · Average cost: $1,000 - $5,880. Low End. $1,000. Average. $3,440. High End. $5,880. The average costs of an electric boiler installation can range between $1,000 to $5,880 in total price. An electric boiler relies on electricity to generate heat, and they can be highly effective at warming a home or a home's water supply.Learn More

    Sep 01, 2010 · 1.. IntroductionDissipation heat loss, which is often expressed as a percentage form, is the heat dissipated from the surface of a boiler to surroundings through convection and radiation, .For pulverized coal-fired boilers in power plant, as the structural styles of the boilers are relatively limited and dissipation heat loss is normally below 1% of thermal input, a single value from Learn More

  • Heating load vs. electrical load all ends up as heat

    Mar 22, 2013 · At $1.25/therm gas in an 80% efficiency cast iron pig of a sub-code-legal boiler you get 64,000 BTU/$ of heat into the home. (Condensing boilers do better, at ~76,000BTU/$) The cost of pumping that sensible heat out with crummy window air-conditioners during the cooling season is about 1kwh to every 3-4kwh of plug load too, and that's not free.Learn More
