Many pool owners make the mistake of “switching off” their pools or not adding any chemicals during the winter. While you might not be swimming, a total shutdown and no chemicals been added leads to a costly swampy mess by spring. Use the cooler months to save on electricity while keeping the water healthy. 

1. Reduce Pump Run-Time 

You do not need to run your pump for 10 hours in mid-winter. Since there is less heat and lower bather load, 4 to 5 hours of filtration is usually sufficient. This significantly reduces your monthly electricity bill without compromising water clarity. 

2. Monitor Salt Chlorinators 

If you use a saltwater system, be aware that salt cells are less efficient in cold water. Many units have a “winter mode.” Check your chlorine levels regularly to ensure the cell isn’t overworking or under-producing. If the unit does not have a Winter mode, just manually turn it down to a lower setting .

3. Don’t Stop Testing 

Evaporation slows down in winter, Test your water at least once every two weeks. Maintaining a balanced pH and TA ,with these levels been correct ,the water will not go acidic and do damage to the pool surface or equipment , that means you won’t have to spend a fortune on trying to balance the water when spring arrives. 

4. Address Necessary Repairs 

Winter is the best time to service your equipment. If your pump has been noisy or your filter sand is over 2 years old or even leaking pipework, get it sorted now. Pool professionals are less busy during the off-season, often resulting in faster service and better rates.

5. Keep it Covered 

A solid pool cover is a winter essential. It prevents leaves from entering the water, reduces chemical evaporation by up to 90%, and acts as a vital safety barrier.
