What is the Cheapest Way to Run a Lazy Spa? Cost-Saving Tips and Tricks

what is the cheapest way to run a lazy spa

Owning a Lazy Spa, also known as an inflatable hot tub, offers a luxurious way to relax and unwind. However, concerns about the cost of operation can dampen the experience. Fortunately, there are several strategies you can implement to run your Lazy Spa in the most cost-effective manner. This article will explore practical tips to help you enjoy your spa without worrying about high expenses.

Understanding the Costs

The primary costs associated with running a Lazy Spa involve heating the water, maintaining water quality, and powering the jets. Energy efficiency is key to minimizing these costs. Let’s look at how you can achieve this.

Cost-Saving Tips for Running a Lazy Spa

1. Use a High-Quality Insulating Cover:

  • A well-insulated cover is essential for preventing heat loss. Ensure the cover fits perfectly and is in good condition to effectively retain heat when the spa is not in use.

2. Maintain a Consistent Temperature:

  • Constantly heating the water from a low temperature consumes more energy. It’s more economical to maintain a consistent moderate temperature.

3. Invest in a Thermal Blanket:

  • A floating thermal blanket can provide additional insulation, further reducing heat loss and energy consumption.

4. Optimize Filtration and Heating Cycles:

  • Use timers to run filtration and heating cycles during off-peak hours, which can be cheaper depending on your electricity tariff.
  • Adjust the duration and frequency of these cycles based on usage to avoid unnecessary energy expenditure.

5. Regular Maintenance:

  • Regularly clean and maintain your Lazy Spa. A well-maintained spa with clean filters operates more efficiently, reducing energy costs.

6. Choose an Energy-Efficient Location:

  • Place your Lazy Spa in a location that is naturally sheltered from wind and where it can receive some sunlight, as these can help maintain water temperature.

7. Use Energy-Efficient Accessories:

  • If you’re using additional accessories like lights or entertainment systems, opt for energy-efficient options like LED lighting.

8. Monitor Water Chemistry:

  • Keeping the water chemistry balanced not only ensures a safe and enjoyable spa experience but also reduces the need for costly water changes and chemical treatments.

9. Limit Jet Use:

  • While the jets are a luxurious feature, they consume additional energy. Use them judiciously to save on electricity.

10. Insulate the Base:

  • Placing insulation beneath the spa can help reduce heat loss through the bottom, especially if placed on colder surfaces.


Running a Lazy Spa economically is all about optimizing and reducing energy usage while maintaining its functionality and your enjoyment. By implementing these tips, you can significantly cut down on operational costs. A little bit of planning and regular maintenance can go a long way in ensuring that your Lazy Spa is a relaxing retreat that doesn’t break the bank.


How much electricity does a lay-Z spa use?

The electricity usage of a Lay-Z-Spa varies based on factors like the model, size, frequency of use, temperature settings, and your individual energy tariff. Generally, Lay-Z-Spa hot tubs are designed for energy efficiency, featuring a power-saving timer, rapid heating system, and Duraplus construction for better heat retention.

Average weekly running costs for a Lay-Z-Spa in the UK, based on 2023 data, are approximately:

  • Summer: £7.63–£10.38 for weekend use and £11.77–£19.17 for full-week use
  • Winter: £10.80–£15.45 for weekend use and £16.11–£25.38 for full-week use

These costs are based on an energy tariff of 30p per kWh, assuming the water is heated to 40°C and the Airjets are used for up to 1.5 hours per week. The use of a thermal cover can lower these costs.

Each Lay-Z-Spa model typically has a standard voltage of 2.05 kWh. To estimate your running costs, multiply this by the number of hours you use your hot tub per week/month and then by your energy tariff.

For example, for an 806L model at a £0.40 per kWh tariff with 50 hours of use per month, the cost would be about £41 per month. A larger model, like the 1190L, may take more hours to heat and thus increase the cost to around £65.60 per month for 80 hours of use.

It’s generally more cost-effective to leave the Lay-Z-Spa running, especially with the frost protection system maintaining the water at 6 degrees Celsius. Additional measures like using an insulated ground mat and filling the tub with warmer water can further reduce energy costs.

How can I reduce the energy cost of my Lazy Spa?

To reduce energy costs, use a high-quality insulating cover, maintain a consistent water temperature, invest in a thermal blanket, and run filtration and heating cycles during off-peak hours. Regular maintenance and careful use of jets also help in reducing energy consumption.

Is it cheaper to leave my Lazy Spa on all the time?

It’s usually more cost-effective to maintain a consistent temperature in your Lazy Spa rather than frequently heating it from a low temperature. However, if you’re not using the spa for an extended period, lowering the temperature can save energy.

How often should I change the water in my Lazy Spa to be cost-effective?

Water change frequency depends on usage but typically, changing the water every 1 to 3 months is sufficient. Maintaining water chemistry and using a cover can help keep the water clean for longer, reducing the need for frequent changes.

Does the placement of my Lazy Spa affect its energy efficiency?

Yes, placing your Lazy Spa in a sheltered area that’s protected from wind and receives some sunlight can help maintain the water temperature naturally, reducing heating costs.

Are there any energy-efficient accessories I should consider for my Lazy Spa?

Opt for energy-efficient accessories like LED lights and low-energy filtration systems. These accessories enhance your spa experience while minimizing additional energy consumption.

How does a thermal blanket help in reducing running costs?

A thermal blanket provides an additional layer of insulation on the water’s surface, reducing heat loss, thereby decreasing the energy required to maintain the desired water temperature.

Can the use of jets increase energy consumption?

Yes, frequent and prolonged use of jets increases energy consumption as they require additional power. Use them judiciously to enjoy the benefits without significantly increasing energy costs.

What is the most cost-effective way to maintain water chemistry in my Lazy Spa?

Regularly testing and adjusting the water balance using cost-effective testing kits and chemicals can maintain water quality. This approach reduces the need for expensive treatments and water changes.

Does insulating the base of the Lazy Spa make a difference?

Yes, insulating the base of your Lazy Spa can significantly reduce heat loss, especially when placed on cold surfaces, thus enhancing energy efficiency.

Is it necessary to use a professional for Lazy Spa maintenance to save costs?

While professional maintenance can ensure optimal performance, many cost-saving maintenance tasks can be done yourself, like cleaning filters and monitoring water chemistry.
