What is the most efficient water heater for domestic hot
Example – 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
