How to calculate gas heater

Recommended Posts


9 minutes according to the calculator. Your 2500gph pump will not meet the 6gpm flow rate. Not sure what effect that will have, or if the heater will operate at a lower flow rate. Also, that will be some seriously hot water returning to the spa which could be a problem for your pipes or anyone who touches the return flow while in the spa.
