Spa Pool Running Costs for 2025: Electricity Usage & Savings

Hi, I’m Andrew Pullen, Managing Director of Vortex Spas™. If you’re curious about how much electricity your spa pool uses, you might be pleasantly surprised.

Thanks to advancements in technology, modern spa pools are more energy-efficient than ever. In fact, a high-quality spa can cost as little as $30 per month to run, and even less if you opt for an energy-efficient heat pump.

Full disclosure, as the Managing Director of Vortex Spas™ and someone who has spent many years in the industry, I have a deep understanding of how spa design affects energy consumption. While I do have a vested interest in selling premium models, I’ve seen time and again how investing in a high-quality spa with better insulation can dramatically reduce running costs over the long term.

What Impacts Spa Pool Running Costs?

Several factors influence the electricity consumption of a spa pool. Understanding these can help you make informed decisions to lower your running costs.

From the climate where you live to the type of spa you choose, each aspect plays a significant role in determining your energy usage.

By focusing on insulation, efficient heating methods, and choosing a high-quality spa, you can drastically reduce your monthly power bills and enjoy long-term savings. Let’s break down the key elements that impact your spa’s energy efficiency.

The amount of electricity your spa pool uses depends on the following 7 key factors:

1. Spa Quality: Cheaper spas typically cost more to operate due to poor insulation and inefficient components. By investing in a modern, well-insulated spa, you’ll enjoy lower running costs over time. Although the initial price is higher, a quality spa can last up to 20 years—meaning substantial savings on power bills in the long run. Given the lifespan of a good spa, it’s wise to invest upfront and take every step to reduce ongoing energy expenses.

2. Insulation Quality: Spa insulation is critical when it comes to energy efficiency. Spas with full-foam insulation and high-quality covers retain heat far better, which helps reduce heating costs. If your spa isn’t well insulated, you’ll find yourself spending more to maintain a comfortable water temperature.

3. How You Heat the Spa: The method you use to heat your spa can have a big impact on energy consumption. Most spas come with electric heaters, but upgrading to a highly energy-efficient heat pump can make a significant difference. (More on this below.)

4. Local Electricity Costs: Higher regional electricity rates directly affect running costs, so it’s essential to factor in your local pricing when estimating spa expenses.

5. Spa Size and Type: Larger spa pools naturally require more electricity to heat, circulate water, and run the jets. Premium spas like Vortex™ and Jacuzzi^® models are built to be energy-efficient with better insulation and technology designed to reduce power usage without sacrificing performance.

6. Frequency of Use: How often you use your spa also plays a significant role. Frequent use requires more heating and circulation, which increases electricity consumption. On the flip side, keeping your spa at a constant temperature rather than heating it up each time you use it can reduce spikes in energy use.

7. Location and Climate: If you live in a cold climate, your spa will need more energy to maintain its temperature, especially during winter. Warmer regions, on the other hand, will see lower energy use, particularly in the summer.How You Use the Spa: Running the jets and water features typically uses more power. The more often the jets are on, the higher the electricity consumption.

First and foremost, the biggest impact on the energy efficiency of your spa is the quality of the spa you buy. As explained above, cheaper spas tend to cost more to run. If you want low running costs, investing in a quality, modern spa is the first place to start.

Yes, they cost more upfront, but a good spa should last up to 20 years—that's a lot of power bills. You may as well do everything you can at the start to reduce those ongoing costs.

Cost Estimates for Spa Pool Electricity Use

Here are some ballpark figures based on average usage and electricity rates:

• Summer (warmer months): For a well-insulated premium spa, you can expect to pay between $30 and $50 per month on electricity.
• Winter (colder months): In colder regions, monthly costs can rise to between $60 and $80 per month.

It’s worth noting that cheaper, less-insulated spa pools can cost significantly more to run, especially in extreme climates.

In some cases, running costs can climb to $100 or more per month during the colder months. Additionally, local electricity rates will impact your overall costs, so be sure to check those before making any long-term budgeting plans.

Why do Premium Spas Cost Less to Run?

Premium spas, such as the ones we offer at Spa World, are designed with energy efficiency in mind. Brands like Vortex™ and Jacuzzi^® Spas include features like full-fill and full-foam insulation, thick covers, and energy-efficient circulation pumps.

These design elements are intended to minimise heat loss, reduce power consumption, and ultimately save you money in the long run.

High-quality spas can reduce electricity use by 20 percent to 30 percent compared to cheaper models that lack the same energy-saving features.

Remember, a spa is a long-term investment. Choosing a premium spa now means lower power bills for decades to come.

How to Reduce Spa Pool Running Costs

Reducing your spa pool’s energy consumption doesn’t have to be difficult. Here are some practical steps you can take:

1. Consider Installing a Heat Pump

Heat pumps, such as the SpaNet^® EcoCube™, can reduce spa running costs by up to 75% by converting ambient air into heat efficiently. They typically pay for themselves in 18 months through energy savings, making them a great long-term investment.

2. Buy the Best Spa You Can Afford

Premium spas come with superior insulation, energy-efficient pumps, and smart controls. Though they cost more upfront, they provide long-term savings on electricity bills and last up to 20 years, making them a wise investment.

3. Invest in a High-Quality Spa Cover

An insulated cover helps trap heat when the spa is not in use, preventing heat loss and significantly reducing the energy needed to maintain temperature. It’s one of the simplest ways to cut running costs.

4. Lower the Water Temperature

Dropping the temperature by just a few degrees when the spa isn’t in use can reduce electricity consumption without impacting comfort. Using an “eco” setting during inactivity is a great way to conserve energy.

5. Use Energy-Efficient Settings and Features

Many premium spas come with smart controls that optimise heating and filtration cycles based on usage. Take full advantage of these features to ensure you’re not using more energy than necessary.

6. Install a Windbreak or Enclosure

Protecting your spa from wind or cold air with a windbreak or enclosure can dramatically reduce heat loss, lowering the energy required to maintain water temperature.

7. Maintain Your Spa Regularly

Keeping your spa well-maintained—ensuring filters are clean, water is balanced, and components are functioning correctly—helps it run efficiently. Regular maintenance reduces the strain on your spa, extending its lifespan and optimising energy usage.

Conclusion

Owning a spa pool offers great relaxation and therapeutic benefits, but managing running costs is key to long-term enjoyment.

As someone who has worked in the spa industry for years, I can confidently say that investing in a high-quality, energy-efficient spa is the best way to keep electricity bills low.

By using smart practices like installing a heat pump, maintaining your spa regularly, and using energy-efficient features, you can enjoy your spa without worrying about high expenses.
