Assuming the boilers operate six hours per day to meet hot water demands, the boilers will be in standby mode for 18 hours (a very reasonable and conservative assumption). It follows that Pump A, running intermittently, will accumulate about 6 hours of run time, while Pump B, running continuously, will have run for 24 hours straight.
