BHP X 34.5 ÷ 8.337 ÷ 60 X 1.5 = gpm. (Please note that the 1.5 is, once again, a safety factor.) For the example we have been using the calculation will look like this: 500 BHP X 34.5 ÷ 8.337 ÷ 60 X 1.5 = 52 gpm. Another quick rule of thumb is that 1/10 of a gallon is needed for every boiler horsepower.

### What size circulator pump for boiler? - DoItYourself.com

SELECTION OF CIRCULATION PUMP. Circulation pump flow rate is detected with the amount of water circulating in the installation. The water circulating in the installation is dependent on the total heat requirement of the installation and forward-return temperature of water. Q k. Q p = C.p.(t g-t d) Q p : Pump flow rate (m 3 /h) Q k : Heat requirement (kcal/h)

Since most of the radiant heating systems utilize a 20F temperature drop, the formula can be changed to: 1 GPM = 10,000 BTU/hr, meaning that for every 10,000 BTU's of heat load the circulator must output a 1 gallon per minute flow.
