    The system heating load is currently 250 M BTUH and standby losses are assumed to be 2.5%. In order to generate 250,000 BTUH of usable output, modulating Boiler A will fire continuously at 31.6% fire with a thermal efficiency of 79% (1,000,000 x 31.6% x 79% = 250,000 BTUH). Since Boiler A is firing continuously, it will not have any standby losses.Get Price
