Hot Tub Maintenance Tips: A Seasonal Guide for UK Owners

Owning a hot tub in the UK can be a dream, but like any valuable investment, it requires ongoing care to keep it functioning smoothly. Each season brings unique challenges, from summer’s frequent use to winter’s freezing temperatures. Here’s a complete seasonal guide to hot tub maintenance, tailored to UK owners.

Winter Maintenance: Protecting Your Hot Tub from Frost

Winter can be a tough time for hot tubs, with freezing temperatures potentially causing damage to pipes and jets. The key to winter maintenance is ensuring your hot tub stays protected and properly heated.

Key Winter Maintenance Tips:

Maintain the Temperature: Even if you’re not using your hot tub regularly during winter, keep the water temperature above freezing. Most owners keep their hot tubs at around 30°C (86°F) during the winter months to prevent water from freezing.
Use a Quality Cover: Invest in a well-insulated cover that prevents heat loss and keeps debris out. Consider adding an extra thermal blanket or cover cap for additional insulation.
Drain or Not to Drain: If you plan on not using your hot tub at all during winter, you can drain it. However, it’s critical to ensure that all water is removed from the pipes to prevent freezing. If in doubt, consult a professional for winterization services.
Check the Water Level: Ensure the water level stays high enough to cover the pump intake. If the water level drops too low, the pump may run dry and burn out.
Monitor Water Chemistry: Even during periods of infrequent use, keep an eye on your water chemistry. Cold weather can still lead to imbalances, and bacteria can still thrive if chlorine or bromine levels drop too low.

Spring Maintenance: Prepping for Prime Hot Tub Season

Spring is the ideal time to get your hot tub ready for the upcoming months of increased use. This is also a great opportunity for a thorough clean and refresh after winter.

Key Spring Maintenance Tips:

Drain and Refill: Start the season with a clean slate by draining and refilling your hot tub. Over winter, your water may have become less balanced, and a fresh fill ensures optimal water quality.
Deep Clean the Shell: While the tub is empty, give the shell a deep clean. Use non-abrasive cleaners designed for hot tubs and a soft cloth or sponge to remove any grime or scale buildup.
Clean or Replace Filters: Spring is a good time to clean your filters thoroughly or replace them if needed. Soak them in a cleaning solution overnight to remove any oils or dirt, then rinse them thoroughly before reinstalling.
Test Your Equipment: Check that your pump, jets, and heating system are all functioning properly. Spring is the best time to address any issues before the busy summer season arrives.
Balance Water Chemistry: After refilling, use a test strip or liquid test kit to check pH, alkalinity, and sanitizer levels. Adjust as needed to keep the water balanced.

Summer Maintenance: Keeping Your Hot Tub Fresh During Peak Usage

During summer, your hot tub will likely see the most action, so staying on top of maintenance is crucial for a great user experience.

Key Summer Maintenance Tips:

Water Balance: With frequent use, your hot tub’s water chemistry can change rapidly. Test the water every few days and adjust pH and sanitizer levels as needed. Keep chlorine between 3-5 ppm (parts per million) or bromine between 3-5 ppm.
Keep It Clean: With more people using the hot tub, it’s important to stay on top of cleanliness. Use a skimmer net to remove debris daily, and give the waterline a wipe-down to prevent buildup.
Shock Treatments: Periodically “shock” your hot tub with a dose of oxidizer to destroy organic contaminants that regular sanitizers might miss. A chlorine-based shock works well for summer maintenance.
Check Filters Weekly: During peak use, check and rinse the filters more frequently—at least once a week. This helps maintain water flow and keeps the water crystal clear.
Monitor Water Levels: With higher temperatures and frequent use, water can evaporate quickly. Top up the water regularly to ensure the pump stays fully submerged.

Autumn Maintenance: Preparing for Cooler Weather

As summer fades into autumn, it’s time to prepare your hot tub for reduced use or potential winter hibernation.

Key Autumn Maintenance Tips:

Inspect the Cover: Autumn is the perfect time to inspect your cover for any damage. As colder weather approaches, you’ll want to make sure the cover is in top condition to prevent heat loss.
Consider Draining: If you know you won’t be using your hot tub much over the colder months, now is a good time to drain and clean it. Leaving stagnant water sitting for extended periods can lead to algae growth or imbalanced water chemistry.
Add Insulation: To prep for winter, consider adding extra insulation around your hot tub. If it’s placed on a deck or raised surface, installing insulation underneath the tub can help retain heat.
Chemical Storage: Ensure your hot tub chemicals are stored correctly as the temperatures drop. Keep them in a cool, dry place away from direct sunlight to preserve their effectiveness.

Year-Round Chemical Use and Storage

Throughout the year, maintaining the right balance of chemicals is essential for clean, safe water. Whether you use chlorine or bromine, ensuring the correct levels is vital.

Key Chemical Guidelines:

Sanitizers: Chlorine should be kept between 3-5 ppm, while bromine should be kept at similar levels for optimal sanitization.
pH Levels: Maintain your pH between 7.2 and 7.6 to prevent irritation to bathers and protect your equipment from corrosion.
Total Alkalinity: Keep alkalinity between 80-120 ppm to buffer your water’s pH levels.
Calcium Hardness: Calcium levels should be kept at 150-250 ppm to prevent scale formation and corrosion.

By following these seasonal tips, you’ll ensure your hot tub stays in excellent condition year-round, no matter what the British weather throws at you. If you need any of the chemicals or tools mentioned please check our website or contact The Pool Cleaners’ friendly support team for advice.
