Nov 30, 2015 · This equation is based on the criteria that there is no vaporization occurring in the heater. The KW equation incorporates a 20% safety factor, allowing for heat losses of the jacket and piping, variation in voltage and wattage tolerance of the elements. KW = (M x ΔT x x Cp x S.F.)/3412 . Where: KW …Learn More
Sep 08, 2019 · How to calculate the power consumption of the electric boiler? 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 …Learn More
Sep 06, 2001 · The calculations for the figures in Table 1 assume that only 10 boiler horsepower (bhp) is needed for process heating and the central boiler has a nominal 150 bhp rating. This is the energy output of the boiler at rated capacity, and one bhp is equivalent to 34.5 pounds of steam per hour or 33,446 Btu/hour (mean) at 212 ° F and higher.Learn More
15 to 20 radiators: 30–40 kW And for a heat only or system boiler: Combi boilers need more power because they heat up the hot water instantly, whereas system and heat only boilers do it more slowly by circulating hot water around the cylinder. So while combi boilers might look much less efficient, they are different systems. Get a quoteLearn More

The power output of a boiler is measured in kilowatts (kW) and helps to give an idea of the level of heating and hot water demand the boiler will be able to meet. Simply put, the higher the kW rating, the more radiators and taps it can supply at any one time.Learn More
Oct 19, 2020 · So if i understand your math, a 3kw electric boiler is more than sufficient? My local dealer who sells the thermo 2000 use a basic calculation of new houses (new building codes) require 22btu/ft2 and old houses 35btu/ft2. I was looking at 30,000 btu in my situation = 9kw. That would be overkill. Thanks again.Learn More

Feb 17, 2020 · If your home has 2 or more bathrooms, a combi boiler may not be able to cope with the high hot water demand. We recommend that you install either a system or conventional boiler with a central heating output of 35 - 42kW. A system boiler includes a hot water storage cylinder, whereas a regular boiler includes a cylinder and cold water tank.Learn More
