I look after a 90,000gal pool (residential, not commercial) and need to look at heaters...
Currently I have three jandy electric heaters (120k-btu each) which struggle on cool days to get the temp up (they are quite old now!)
So.....being a rental property, the pool is only heated a few times a year, for maybe a week or so at most. Thats good, but I have to start heating from scratch every time.
I do not have natural gas and I'm restricted to the size of LP container I can have (local code).
Should I just replace the 3 heaters I have with new (whats the largest btu I can buy?) OR, look at mix-and-match electric and LP??
Is there a commercial heater available (electric)?
any suggestions most welcome!
