In Summation-for most inground pool owners, installing a New pool heater (not a replacement, which has a cheaper installation cost), new pool heaters cost between $1500-$3500, depending on type and size. The cost to run a pool heater, with some conservation practices, runs from $0 (solar heater) to over $300 per month.
Heat pump pool heaters cost more than gas pool heaters, but they typically have much lower annual operating costs because of their higher efficiencies. With proper maintenance, heat pump pool heaters typically last longer than gas pool heaters.200. $800. *Based on an electric resistance heated pool, which costs $1,000 per year at an electric cost of $.085/kwh, and using a natural gas cost 0f $.80/therm. A seasonal average COP of 5.0 was used to determine heat pump savings.
