Quick estimate: how much a cover can reduce heating cost by cutting heat loss.
This calculator estimates how much heating cost may be avoided by using a pool cover. Enter the daily heating cost without a cover, choose an estimated heat-loss reduction, and add the number of heated days per month.
The tool multiplies the daily cost by the selected reduction percentage and the number of heated days. An optional season length provides a rough seasonal estimate.
Evaporation is one of the largest sources of pool heat loss. A cover creates a barrier between the water and the air, which can reduce evaporation, slow overnight cooling, and help the heater maintain temperature with less runtime.
The biggest savings usually come from consistent use, especially overnight and during windy weather.
It can in some conditions, especially when evaporation is the main source of heat loss and the cover is used consistently. Results vary by climate and pool operation.
It can help retain solar gain and reduce heat loss. Its greatest value is often preventing the heat already in the pool from escaping.
That depends on sunlight, wind, swimmer use, and water temperature. Consistent nighttime use usually provides the clearest benefit.
Use actual fuel or electricity data when possible. A gas-heater or electric-cost calculator can provide a planning estimate when bills are not available.
The cover only saves money when it is actually on the pool. A perfect cover rolled up beside the deck saves exactly nothing.
