I have 2 old boiler in my care and need to install a boiler feed pump, this require the HP of the boiler. There are 60 of the small ceramic burners in each boiler. I am remembering 16k or 12K btu each, but I am most likely completely wrong.
The boilers provide steam heating and steam for domestic hot water. It is located in Oakland, CA at the Claremont Country Club. It started as an oil burner, and was converted to natural gas at some point. I use to just count the burners and multiply by the know BTU of the ACME burners, but I don't remember the sizing. I guess I could clock the meter and get an approximation that way.
