Comparing Indirect vs Direct hot water syste

: 570KBExample – comparing efficiencies of direct and indirect fired hot water systems using the Part L method. Direct fired condensing water heater: 96% gross thermal efficiency. An indirect fired calorifier: 96% (taking the condensing boiler’s gross seasonal efficiency). When producing hot water with return boiler temperatures likely to be 60°C or higher, the boiler is more likely to be

H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg) GCV= Gross calorific value of the fuel. Indirect Efficiency. The indirect efficiency of a boiler is calculated by finding out the individual losses taking place in a boiler and then subtracting the sum from 100%. This method involves finding out the magnitudes of all the measurable
