This is totally incorrect. Any NG/LP heater has to go last in line after the filter. Never put a NG/LP heater before a Heat Pump, period.
Additional, are the multiple heat pumps in series or parallel? All heat pumps need to be in parallel, in other words, they all need to be drawing fresh cold filtered pool water and passing it back to the pool (not to any other heat pump) or on to a NG/LP heater.

I have a large pool (80,000 gal) which is in a rental property, as a result the heaters (3 of them!) are off most of the time.
When we have a booking, say once a month, we fire up the heaters and it can take 3-4 days to get up to 85-88!!
If the air temp is low, or it rains we do not even achieve that!
Question: Could I add a LP heater to the row of heat pumps (should it go first or last??) to give that initial boost for heat then allow the HP to keep it there??
Perhaps let the gas heater kick in occasionally when needed??
Any thoughts!
Thanks!
