    It went downhill after that the engineer pointed his finger at the boiler brochure and said “see, it says 99% efficient we are done.” and with that i was out of the office i stopped by the director of maintenance office to explain what happened i showed the director of maintenance the boiler efficiency charts and pointed to the graph that shows that the boiler will indeed reach 99% efficient if the return water is below 70°f and the burner firing rate is at low fire in my area, 70 degree.
