What's your usage rate and temperature? Incoming water temp?
output 130 deg incoming can be down to 40 boiler should put out 500 gph Just wondering what differance the tank will make.
Round numbers, the boiler heats produces 400 gallons per hour. FIRST hour delivery is the recovery rate ( 400 gallons per hour ) PLUS 70% ot tank. SO your first hour availablilty drops from 660 gallons to 485 gallons. After the first hour, it is all recovery, 400 gallons per hour.Quote:
