Pool Heating Cost Calculator
Compare gas, electric resistance, heat-pump and solar thermal heating using your pool, season, energy rates and quotes, including pool-cover savings.
Your pool and swimming season
Length × width for a rectangular pool.
Location sets an illustrative unheated-water temperature only, not weather data. Adjust it for your location and chosen season.
Heated continuously during one season; 180 is an example, not a local recommendation.
Pool cover
Illustrative 50% assumes regular use outside swimming hours. Confirm with your installer.
Added to every option when enabled. Use zero for a cover you already own.
Energy rates and installed quotes
Enter 0.30 for 30 cents. Uses grid electricity for all electrical consumption.
Include all installation costs; use confirmed net quotes after discounts.
Include all installation costs; use confirmed net quotes after discounts.
Include all installation costs; use confirmed net quotes after discounts.
Include collectors, controls, installation AND a heat pump to supply the remaining heat.
Editable model assumptions
These are example inputs, not measured equipment or climate performance. Ask an installer to validate them.
Example 0.12: ongoing thermal demand per surface area, day and degree above unheated water temperature.
Example 4 means 4 kWh of heat per kWh of electricity, including backup use.
Applied on each season day when solar supplies heat; ordinary filtration is excluded.
