There are a number of factors that you must consider to determine the answer to this question including the location of the pool, if it is an indoor or outdoor pool, bather load (number of people swimming in the pool and how regularly) and weather impacts.
Generally speaking, fresh, mineral and salt water pools are less expensive to run than traditional chlorine pools – in some cases up to 50% cheaper.
Apart from the electricity required to operate the pool filter, other costs to consider may include the purchase or salts or minerals to ensure the pool water has enough salt content for the chlorinator to operate efficiently. This is measured as kilowatts per kilogram of chlorine produced.
In locations where high rainfall is experienced (ie the pool regularly overflows), additional chemicals may be required in order to maintain a healthy water balance. This depends on the size and location of the pool and the severity of rainfall events.
