29-08-2017· The direct method, known as method of input-output, is done by comparing directly the heat energy absorbed by the water so that the change phase into a vapor (output energy) with the thermal energy generated by burning fuel in the boilerâ€™s combustion chamber (input energy).

### What size boiler do I need? Try our power calculat

- ApplicationsWhen calculating your boiler size, you might notice two powers in the specifications of a given boiler. One is the power input, the other is power output. Input says how much energy goes into the boiler to make it work, and output says how much of that energy is converted into usable heat. Efficiency is the percentage of output from the input. lexie@zozen.com > Get A Quote >

Direct method is quick method for boiler efficiency calculation, In this method, Percentage of total heat output vs heat input is calculated to establish boiler performance. Boiler Efficiency = Heat output / Heat Input X 100. Or Boiler Efficiency = Q X (h3 â€“ h1) / (q X GCV) X 100. Where Q = Qty of steam generated.
