New inground pool install almost complete. Vinyl lined concrete wall hard bottom 20x40 3 1/2'-8' depth on long island , NY.
I have a southern exposure in a sunny yard . All of my pool equipment is about 30' from the electric and natural gas line in my garage, so either energy source is an option. I'm trying to decide if I should go with a gas heater or electric heat pump to extend the pool season. I've gotten mixed opinions from
people I know that have pool heaters. LIPA costs are 19 cents per kwh and nartional grid natural gas costs are about 80 cents per therm(100k btu).
How do figure out cost of operation?
