How big of a circulator pump do I need?
How big of a circulator pump do I need?
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. Assuming that system calls for 100,000 BTU/hr, a circulator pump should have a minimum 10 Gallons Per Minute flow rate at a given pressure drop.
Does size of heat pump matter?
Does it really matter if your heat pump isn’t quite the right size? Yes, it really does. That is unless you enjoy paying higher utility costs and extra repair fees. If a unit is too small, it will struggle to produce enough energy to heat and cool your home.

How do you calculate hot water recirculation pump?
Determine Pump Head & Select Pump. Given that our recirculation line is 300 feet in lenth, and our flow rate is 1.9 gpm (rounded up), we must calculate the total friction loss: Pipe pressure drop = 300 ft. x 1.4/100 = 4.2 ft.
What happens if heat pump is too big?
If your heat pump is too large for your home, it will short (or rapid) cycle, which isn’t healthy for the motor. If too small, it will constantly try to run to meet your temperature needs. Not only are both issues annoying, but it can cost you.
