How to Protect Your Hot Tub During a Winter Power Outage in Alberta


Eco Spa Hot Tub Ice


In Alberta, where winter’s grip can be relentless, the prospect of a power outage is not just an inconvenience—it can be a potential disaster for your backyard oasis. Hot tubs, with their comforting jets and soothing warmth, can become cold, lifeless pits of despair without a steady power supply. For those fortunate enough to own an Eco Spa, with its integrated Eco Hard Cover and top-tier insulation, the impact of a power outage can be mitigated, but the situation still requires immediate action. Here’s a comprehensive guide on what to do with your hot tub if the power goes out in Alberta, ensuring you stay warm and worry-free, no matter how harsh the winter gets.


Understanding the Time Frame

Eco Spas have excellent insulation and heat retention due to their integrated Eco Hard Cover with power clamps. However, in the event of a power outage, the water temperature will gradually drop. Here’s a rough timeline of what to expect:

  • First 12 hours: The water temperature will start to drop but should remain relatively warm, thanks to the superior insulation and airtight cover.

  • 12-24 hours: Depending on the external temperature, the water will continue to cool. If the temperature is extremely low, the water could approach freezing.

  • Beyond 24 hours: Without intervention, the risk of freezing increases significantly, especially if the power outage persists and the external temperature remains well below freezing.


Immediate Steps to Take

1. Secure Your Hot Tub with the Eco Hard Cover

Your Eco Spa comes equipped with an innovative Eco Hard Cover. This cover is not just a simple barrier; it features power clamps that compress the seals all around the tub, ensuring an airtight and watertight seal. If the power goes out, the immediate step is to secure this cover as tightly as possible. This will help retain the heat in the water and prevent the cold air from penetrating, maintaining a more stable temperature inside the tub.


2. Keep the Cover Closed as Much as Possible

To minimize heat loss, it's crucial to keep the cover closed as much as possible. Each time you open the cover, a significant amount of heat escapes, which can accelerate the cooling process. Only open the cover if absolutely necessary, and do so quickly to limit exposure to the cold air.


3. Monitor the Temperature

Without power, the heater and pump will be non-operational, and the water temperature will begin to drop. It’s essential to keep an eye on the thermometer, if you have one, to gauge how quickly the temperature is falling. Your goal is to prevent the water from dropping below freezing. While the Eco Hard Cover will help, the surrounding cold air can still have a significant impact.


Using Alternative Heat Sources

3. Add Hot Water

If you have access to hot water from another source, such as a hot water heater or a portable heating device, you can use this to supplement the heat in your hot tub. Here’s how to do it effectively:

  • Hot Water Addition: Carefully add hot water to the tub. Be cautious not to overflow or damage the system. Boiling water is not necessary; just ensure the water is hot enough to make a difference but not so hot that it could harm the tub’s components.


4. Use a Backup Generator

Investing in a backup generator is a smart move for any hot tub owner in Alberta. This can keep your hot tub’s essential systems running, including the heater and circulation pump. Here’s what to consider:

  • Generator Size: Make sure your generator is appropriately sized to handle the load of your hot tub’s heater and circulation pump. Consult your hot tub’s manual for the wattage requirements.

  • Proper Setup: Place the generator in a well-ventilated area, away from the hot tub, to prevent any carbon monoxide build-up. Follow all safety guidelines and start the generator as soon as the power goes out.


Portable Heating Options

7. Consider Portable Heating Options

For those in more remote areas or facing extended outages, portable heating options can be a game-changer:

  • Camping Heaters: Small, propane-powered camping heaters can be effective. Place them safely around the perimeter of the hot tub, ensuring they do not come into direct contact with the water or any electrical components.

  • Heat Lamps: Infrared heat lamps can provide localized warmth. Position them strategically around the hot tub area to help maintain the water temperature without direct contact.


Stay Informed and Prepared

8. Emergency Kit

Preparation is key when dealing with power outages, especially in a region as unpredictable as Alberta. Here’s how to stay prepared:

  • Emergency Kit: Keep an emergency kit stocked with essentials like blankets, warm clothing, non-perishable food, and flashlights. This will help you stay comfortable and safe while waiting for power to be restored.

  • Weather Updates: Stay updated with local weather reports and power outage updates. Many utilities provide real-time updates on their websites or through mobile apps.


Draining the Hot Tub

9. Drain the Hot Tub as a Last Resort

If the power outage is prolonged and you cannot maintain the water temperature, draining the hot tub is your last line of defense. Here’s a quick guide:

  • Drain Completely: Use the hot tub’s drain valve to empty all the water. Ensure all water is removed from the system to prevent freezing damage.

  • Clean and Store: Once drained, clean the hot tub thoroughly and store it in a sheltered location to protect it from the elements until power is restored.


In Alberta, where winter storms can be fierce and power outages a common occurrence, knowing what to do with your hot tub during a power outage is essential. With the robust features of Eco Spas, including the Eco Hard Cover and top-notch insulation, you have a strong foundation to keep your hot tub functional. By following these steps—securing the cover, using alternative heat sources, activating a backup generator, insulating internal plumbing, and manually circulating water—you can enjoy your hot tub even when the power is out. Stay prepared, stay warm, and turn your hot tub into a winter haven, no matter the weather.
