Insulation & Running Costs
Master Spas builds our swim spas to be used year-round in every possible climate. Environmentally-friendly Icynene foam insulation makes H2X Swim Spas by Master Spas among the most energy efficient swim spas in the industry.
Every swim spa is built to not only meet but to exceed the stringent California Energy Commission (CEC) efficiency regulations. All resulting in what really matters — a superior swim spa experience and savings for you and your monthly utility bill.
Advantages of Icynene Insulation Over Urethane Insulation:
- Icynene Foam retains its insulating value for the life of the product unlike Urethane based foam that can lose 50% of its insulating value within two years.
- Icynene does not produce any harmful off-gas.
- Icynene is mold and mildew resistanty.
- Icynene is the only insulating material certified by the Envirodesic Certification Program for healthier air quality.
Many people understandably ask: how much will a Master Spa hot tub cost to run?
This question is near impossible to answer with any degree of accuracy as it depends entirely on a series of factors, not least:
- The cost of your domestic electric
- Water temperature and ambient temperature
- Wind speed and will-chill factor
- Frequency and duration of use
What we can tell you is Master Spas manufacture some of the most thermally-efficient hot tubs in the world. In addition, they are thermally tested to pass, or exceed, the standards set by the CEC – Californian Energy Commission with publicly available results.
These results give energy use, on standby, in controlled conditions, from which you can calculate anticipated costs.
Visit the CEC website to find the energy use of your Master Spas model
https://cacertappliances.energy.ca.gov/Pages/ApplianceSearch.aspx Simply select the manufacturer and then select the model you wish. Note: Currently some models are still waiting for certification – this is simply because they are newer than others – they share the same build and efficiency so if you want to get an idea, simply pick a similarly sized model with a similar water volume.
The costs indicated on the Energy Calculator are calculated based on the industry’s only certified test procedure for determining energy costs. Actual owner monthly costs will vary on a wide variety of circumstances.
Values have been calculated based on standard test procedure for Portable Electric Spas as stipulated in ANSI/APSP/ICC-14 2014
- Tested at 60°F ambient temperature.
- 102°F water temperature.
- Master Spas cover used and not opened during testing.
- Pumps came on during automatic cycles only for heating and filtering. They were not turned on manually.
- Test conducted in a 3rd party approved environmental chamber certified to the ANSI/APSP/ICC-14 2014 standard.
Actual Monthly Cost of Running a hot tub or swim spa will vary from these totals and is totally dependent upon:
- Local energy cost.
- Local ambient temperature.
- Set water temperature.
- Use of hot tub or swim spa.
- Type and condition of cover.
- Filter cycle settings.

VIP Swim Jets
Think about a high-definition, flat screen TV versus a standard-definition, colour tube TV. One, you couldn’t wait to hang on your wall, and made your house the preferred location to catch the big game or don’t-miss season finale. The other is gathering dust in your garage. They both call themselves TVs, but which one did you prefer?
Can you recall the first time you watched a show in full HD and then switched back to an SD channel? You may have thought your TV was broken, your eyes had gone bad or BOTH. Meet the world’s only HD swim spas, the H2X Series in Hi-Def, by Master Spas.
Introducing the world’s only high-definition line of swim spas, the H2X Series by Master Spas. No other jetted swim spa even comes close.
Our VIP Technology brings you HD performance in an SD world.
Here’s How it Works: The Velocity Injector Cones, along with the water flowing through the jets, help to create negative pressure around the perimeter of the jet face allowing water to be pulled through the front grill, into the main water stream. The result is an IMPRESSIVE 45% performance increase over a standard jetted swim spa.
Once in the water, you’ll find that the H2X has a large flat floor with no hidden obstacles, making it the perfect choice for a variety of fitness exercises. You can jog in place against a gentle current, use a kickboard or use the H2Xercise System that includes a rowing kit, resistance bands, H2Xercise Bells, H2Xercise Fins, the H2Xercise Aquatic Workout book and comes standard with all models.
With the jets off, you can experience the benefits of resistance training and range-of-motion exercises. Water buoyancy naturally makes exercising easy on the joints and this approach offers a total mind and body workout that is effective, yet gentle.
H2Xercise Bells: This unique design allows for adjustability in four varying resistance levels to accommodate any user and fitness level. Whether the goal is rehabilitation or high-level performance training, these are the dumbbells for you.
H2Xercise Ankle Fins: These form fitting, comfortable fins provide a smooth accommodating resistance in every direction that you move. They allow you to strengthen the muscles that you use every day in an effective and efficient manner.
H2Xercise Rowing Kit and Resistance Bands: Easy to connect, use the rowing kit for upper body strength and endurance training. When you’re done, just release the four fastening points and store it in the durable H2Xercise bag for your next session. Multiple resistance bands and attachments are perfect for a wide variety of strength and flexibility exercises.
H2Xercise Aquatic Workout for Every Fitness Level: A new way to exercise. Dr. Rick McAvoy, PT, DPT, CSCS and Professor of Hydrotherapy has authored an exercise program written exclusively for the Master Spas line of swim spas. This program is designed specifically to help you get the most out of your swim spa and is presented in an easy-to-follow format.
