There is also some variance in the fuel efficiency given impurities, temperature, and water presence. Adjusted Fuel Energy Efficiency Wood @ 1.9 KWH per pound and stove efficiency of 70% equals 1.3 KWH/lb

Get a QuoteUsing kW and kWh, you can work out how much gas your boiler is using and therefore how much it costs. A 24 kW boiler will use 24 kWh of energy per hour. According to Choose, the cost is approximately 3.8 pence per kWh, which means it would cost around 91 pence to run a 24 kW boiler for one hour. This will change depending on the cost of gas and the size and age of your boiler.

Get a QuoteBoiler efficiency may be indicated by. Combustion Efficiency - indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust; Thermal Efficiency - indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the boiler, exclusive radiation and convection losses; Fuel to Fluid Efficiency - indicates the

Get a QuoteBoiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.
