Keeping your hot tub in peak condition during winter requires a proactive approach. As outdoor temperatures drop, spa equipment has to work harder, and ice damage becomes a real risk. With a little preparation, you can enjoy cosy soaks all season long while protecting your investment.

Keep your tub running

It might sound counter-intuitive, but letting the spa run through the cold months is one of the best ways to protect it. Maintaining a low, steady temperature helps prevent water in pipes from freezing and causing costly damage. Instead of turning the unit off, set your heater to a lower but consistent temperature so the pump and heater can circulate water and keep everything above freezing.

Start with a deep clean

Before the weather turns, give your hot tub a thorough cleaning. Drain the water, scrub the shell with a gentle cleaner, clean or replace the filters, wipe down all surfaces and then refill with fresh, chemically balanced water. Taking time to remove dirt and oils now makes winter maintenance easier and reduces the risk of bacteria growth.

Invest in a high-quality insulated cover

An insulated cover keeps the heat in and the cold out. A well-fitting cover reduces evaporation and helps retain warmth, which can reduce energy bills. Check your existing cover for signs of wear; if it’s loose or sagging, consider replacing it with one designed for winter conditions. A snug cover also keeps debris, snow and frost from contaminating the water.

Monitor water levels and insulation

Low water levels expose plumbing to air, increasing the risk of freezing. Top up water as needed and check that the cabinet and pipework are well insulated. You can add additional foam insulation around the cabinet if necessary and inspect for leaks or cracks. Ensuring the tub is properly insulated helps it retain heat more efficiently.

Don’t drain the tub for winter

It may be tempting to empty the hot tub completely, but draining it can leave residual water in pipes where it may freeze and expand. Keeping the tub full of balanced water and running at a low temperature is the safest way to prevent ice damage.

Additional winter tips

– Check the cover and seals regularly: Snow and ice accumulation can put stress on the cover. Brush off heavy snow promptly and ensure latches and straps are secure.
– Maintain water chemistry: Even in winter, test and balance your water weekly to keep sanitiser levels within the recommended range.
– Keep the path clear: Make sure the area around your spa is free of ice and snow to prevent slips and allow easy access for maintenance.

Conclusion

Winterising your hot tub doesn’t have to be a daunting task. By keeping it running at a steady temperature, giving it a thorough cleaning, using a quality cover, monitoring water levels, and avoiding unnecessary draining, you can protect your spa from the cold and enjoy relaxing soaks throughout the season. Regular attention now will prevent damage, reduce operating costs and ensure your hot tub is ready to enjoy all winter long.
