Cart is empty Owning a hot tub comes with the promise of relaxation and therapeutic benefits, but without the right energy-saving practices, it can also come with a higher-than-expected power bill. Many hot tub owners in Calgary report winter usage as their biggest energy concern, given the long heating cycles and the need to maintain warm water in sub-zero temperatures.
With smart setup and maintenance choices, you can enjoy your hot tub year-round without draining your wallet.
Start with the Right Hot Tub Model
Not all hot tubs are built the same. Energy efficiency starts at the product level. When shopping, look for hot tubs with full-foam insulation, high-density covers, and energy-smart circulation pumps. Models with programmable controls let you schedule heating cycles during off-peak hours, saving you money on electricity while still ensuring the water is ready when you are.
In Calgary, many homeowners opt for hot tubs specifically rated for cold climates. These models often include thick, marine-grade covers, multi-layer insulation, and freeze protection settings that automatically kick in during harsh weather. Investing in the right tub upfront pays off in long-term energy savings.
When Considering Energy-Saving For Hot Tubs, Place Your Hot Tub Strategically
Where you place your hot tub has a big impact on energy use. A tub exposed to wind, snow, and cold air will lose heat faster than one that’s sheltered. Whenever possible, install your hot tub in a location protected by walls, fencing, or landscaping. Position it near your home to reduce heat loss during walks in colder months and to cut down on installation and plumbing costs.
In Calgary backyards, common placement strategies include building recessed tubs into decks with surrounding privacy walls or placing them under pergolas with drop-down screens. These features don’t just improve aesthetics, they help insulate the tub and trap heat.
Upgrade the Cover, Don’t Settle for Standard
Your hot tub cover is your first line of defense against heat loss. A worn or waterlogged cover allows precious warmth to escape, forcing your heater to work overtime. Check your cover regularly for heavy spots, sagging, or poor seals around the edges. If it’s more than a few years old, it might be time for an upgrade.
Look for a cover with high R-value insulation, a tight fit, and locking straps that keep it in place during windstorms. Some energy-conscious owners even add a thermal blanket underneath the main cover to create an extra layer of insulation over the water surface.
Use a Smart Thermostat or Schedule
One of the most effective ways to cut down on power use is to run your hot tub on a schedule. Most modern models allow you to set specific heating times or let the temperature drop slightly during hours of non-use. If your hot tub has economy or sleep mode, use it.
In Calgary, it’s common to set your tub to drop a few degrees overnight or while you’re at work, then schedule reheating to match your return home. With programmable settings or Wi-Fi control, you can easily make adjustments without stepping outside in freezing weather.
Maintain Filters and Water Chemistry
A clean filter allows your circulation pump to operate more efficiently, reducing energy consumption. Dirty or clogged filters force the system to work harder, leading to higher electrical draw and wear on the pump. Cleaning your filters monthly and replacing them as recommended by the manufacturer keeps everything running smoothly.
Balanced water chemistry also matters. Poor water quality can lead to scale buildup on heating elements and sensors, making them less efficient. Regular testing and adjustment prevent issues and extend the lifespan of your equipment.
Consider a Floating Thermal Blanket
Adding a floating thermal blanket is a low-cost way to reduce heat loss. These lightweight covers sit directly on the water’s surface, minimizing evaporation and insulating the water when the main cover is open or during extended off-periods. They’re particularly helpful during shoulder seasons when the temperature swings between day and night are more drastic.
Some hot tub owners in Calgary use thermal blankets year-round to limit their heater’s runtime, especially when their spa is located in a breezy part of the yard or under partial cover.
Monitor Usage Without Compromising Enjoyment
The biggest myth about energy savings is that you have to use your hot tub less. That’s not the goal. Instead, smarter ownership helps you enjoy it more often without the guilt of high bills. Try setting time limits on long soaks or designating “hot tub nights” a few times per week instead of daily use if you’re watching costs closely.
You can also use a smart home energy monitor to track exactly how much your hot tub consumes. With this insight, you’ll know when it’s running most and can adjust settings to fit your household’s habits and the local utility’s rate schedule.
Frequently Asked Questions – Energy-Saving for Hot Tubs
How much electricity does a hot tub use per month?
On average, hot tubs cost between $25 to $60 per month in electricity, depending on insulation, usage habits, and climate. In Calgary winters, efficient models and smart habits can keep you at the lower end of that range.
Do hot tubs use more energy in the winter?
Yes, especially in cold regions like Calgary, but placement, insulation, and smart scheduling can significantly reduce seasonal energy spikes.
Is it cheaper to keep the hot tub on all the time?
In most cases, yes. Constantly heating from cold uses more energy than maintaining a set temperature. Energy-efficient tubs are designed for this.
What temperature should I set my hot tub to for energy savings?
Many owners keep their hot tub at 100–102°F for comfort. Dropping it to 98°F when not in use can save energy without affecting your soak experience too much.
Can I run a hot tub off solar power?
It’s possible but complex. You would need a substantial solar array and battery storage. In Calgary, where sunlight hours vary, it’s better as a supplemental source rather than a primary.
