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.
