Preparing your hot tub for winter will vary depending on whether you plan to continue using it or not.
As winter approaches, getting your hot tub ready for the colder months is essential to keep it running efficiently and protect it from potential damage. With the right maintenance steps, you can ensure your hot tub remains in optimal condition, whether you plan to use it throughout the winter or close it down until spring. Here’s a guide with essential maintenance tips to prepare your hot tub for the winter season.
Clean and Drain the Hot Tub
Start by giving your hot tub a thorough clean. This includes cleaning the tub itself, as well as filters, jets, and covers. Here’s a quick rundown of each area:
- Clean the Tub: Drain the water completely and use a non-abrasive cleaner to scrub down the sides and bottom. This prevents dirt and buildup from sitting in the tub all winter, which can damage the surface and lead to more intensive cleaning in the spring.
- Clean the Filters: Remove the filters and rinse them with a high-pressure hose to get rid of any debris or contaminants. Consider using a filter cleaner for a deeper clean. If your filters are over a year old, replacing them now might be a good idea to ensure optimal water circulation.
- Clean the Cover: The cover often gets neglected but can accumulate mold, mildew, and grime. Use a cover cleaner and protectant to wipe it down and prevent wear and tear from winter weather.
Once cleaned, let all parts dry before moving on to the next steps. If you plan on using the hot tub during the winter, refill it with fresh water after cleaning.
Inspect the Hot Tub for Any Issues
Inspect your hot tub thoroughly to identify any potential issues that could worsen over the winter. Look for cracks, loose connections, or any visible signs of wear on the shell, cover, and other parts. If you notice any damage, consider scheduling a professional repair before winter sets in. Addressing minor issues now can prevent larger, costlier repairs down the road.
Balance the Water Chemistry
Whether you plan to use your hot tub or shut it down for winter, balancing the water chemistry is essential. Properly balanced water helps prevent the growth of bacteria and protects the internal components from corrosion or scale buildup.
- Adjust pH Levels: The pH level should be between 7.2 and 7.8. Adjust accordingly with a pH increaser or decreaser.
- Check Alkalinity: The ideal total alkalinity is 80–120 ppm. Maintaining this level helps stabilize pH and reduces the risk of fluctuating water chemistry.
- Sanitize the Water: Shock the water to kill any remaining bacteria and clear up any cloudiness. This step is particularly important if you plan to leave the hot tub unused, as stagnant water can quickly develop bacteria.
Protect Against Freezing
One of the biggest concerns when winterizing a hot tub is preventing the pipes and components from freezing, which can lead to expensive repairs.
- Use an Antifreeze Solution: If you’re shutting down the hot tub for the winter, add a non-toxic, hot tub-safe antifreeze to the pipes after draining the tub. This helps prevent any residual water from freezing in the pipes, which could cause them to crack.
- Keep the Heater and Pump Running (If Using in Winter): If you’ll be using your hot tub in winter, make sure the heater and circulation pump are set to maintain a minimum temperature, typically around 80°F. This will help prevent freezing in extremely cold weather.
- Consider a Freeze Protection Setting: Many modern hot tubs have a freeze protection setting that automatically keeps the water moving and prevents freezing when temperatures drop below a certain level.
Check and Maintain the Cover
A high-quality, insulated cover is essential to keep your hot tub warm and energy-efficient during the winter. After cleaning the cover, inspect it for any tears or damage that could allow heat to escape or moisture to enter.
- Secure the Cover: Make sure it fits snugly over the hot tub. If you live in an area with high winds or heavy snowfall, consider using cover straps to keep it firmly in place.
- Add an Insulating Blanket (Optional): An additional floating insulating blanket beneath the cover can help retain heat and reduce energy costs if you plan to use your hot tub in winter. This layer provides extra insulation to minimize heat loss through the water’s surface.
Keep a Regular Maintenance Routine
For those planning to enjoy their hot tub in winter, a regular maintenance schedule will ensure it stays clean, safe, and energy-efficient. Here are a few tips:
- Check Water Levels: Low water levels can cause the pump and heater to malfunction, so be sure to top up the water as needed. Cold air can evaporate the water faster than in warmer seasons.
- Monitor Water Temperature: Extreme cold can cause the water temperature to drop rapidly, so keep an eye on it to ensure your heater is working effectively.
- Perform Routine Water Chemistry Checks: Winter weather can affect water chemistry, so monitor the levels every week or two. Properly balanced water keeps your hot tub hygienic and protects the equipment from damage.
