Cutting the cost

A pool cover is the single biggest saver here, since most heat escapes from the surface overnight and a cover holds it in. Set a modest target temperature and drop it further out of season. If yours is a heat-pump heater, run it in the warmer part of the day when it works most efficiently. Turn heating off well before you stop swimming for the year.
