How Energy Efficient are your hot tubs? Energy price cap will rise by 1.2% from January 2025.

Energy regulator Ofgem has announced a 1.2% increase of the energy price cap for the period covering January-March 2025.


With the rise of energy prices, asking "how energy efficient are your hot tubs", is one of the most important questions to ask a hot tub retailer when purchasing a new hot tub for the first time. However, many hot tub retailers and hot tub manufacturers are starting to make spurious claims about the energy efficiency of their hot tubs, and there are very few that can provide independently tested results to back there somewhat wild and misleading claims... So, you will be glad to know that we can independently verify the energy efficiency on our range of multiple award-winning hot tubs, but more importantly, we have published the independent TÜV SÜD test results below, which demonstrates the energy consumptions based on the latest Ofgem Energy Price Cap increase.

Our Commitment - World's First Net Zero Carbon Neutral Hot Tub and Swim Spa Showroom


In 2021, Penguin Spas took the radical decision to be the world's first net zero carbon neutral hot tub and swim spa retailer by investing in clean green technology for its new 1,283m2 Premium Outdoor Living showroom in South Lanarkshire, Scotland by offsetting the energy used through renewable sources which includes a 30Kw Wood Pellet Biomass heating system along with 10kw of solar cells with the latest TESLA Powerwall (battery that stores energy) which provides all the electricity required for the hot tubs and showroom.

How did you independently test the energy efficiency of your SmartSpa™ R10 hot tubs?


The manufacturer of Sunbeach Spas established the only hot tub factory with witness laboratory of TÜV SÜD Certification in the world. Through several tests in the laboratory of SmartSpa™ R10 insulated hot tubs alongside a direct comparison of a normal insulated hot tubs, the TÜV SÜD experts where able to conduct testing, measurements and certification in-line with the applicable norms and standards to independently certify the energy efficiency of SmartSpa™ R10 insulated hot tubs - See the results below.


TÜV SÜD Testing Certification Hot Tubs and Swim Spas

What is SmartSpa™ R10 and SmartSpa+™ R18 insulation? - Look for the SmartSpa™ Logo.


UK hot tub designer Sunbeach Spas and Oasis Spas introduced the registered trademarks of SmartSpa™ R10, SmartSpa™ R10 Plus and SmartSpa™ R18 Plus to their collection of hot tubs and swim spas earlier last year with the aim of combating the growing number of hot tub retailers across the UK advertising hot tubs with R10 and R18 energy efficiency without any independent certification nor any understanding of what exactly R values are.


Looking for an energy efficient hot tub? Look for the logo!


The New SmartSpa™ R10, SmartSpa™ R10 Plus and the SmartSpa™ R18 Plus logos gives consumers the confidence of purchasing an energy efficient hot tub that has been independently tested and verified of its credentials.


What does a R10 hot tub or R18 hot tub mean?

The R value refers to a materials ability to resist heat flowing through it at a certain thickness. The higher the R-Value, the better it can resist heat transfer. The R Value on our hot tubs are based on the thermal resistance of the hot tub elements which includes the closed cell foam sprayed on the shell, side skirts and base, where contradictory to the U value the higher the R value the better performing the product is, in the sense of reducing heat loss (the higher the R value the better the product is at insulating).




What difference does a hot tub with SmartSpa™ R10 insulation make?

A hot tub with SmartSpa™ R10 insulation will save you on average £124.91 per month or £1,498.90 per year on energy costs. To show the difference between a SmartSpa™ R10 insulated hot tub and a normal heat insulated hot tub, the TÜV SÜD independently tested both hot tubs electricity consumption under specified use conditions and the findings recalculated to reflect the current Ofgem Energy Price Cap @ 27.35 pence per kWh and 53.37 pence per day for the daily standing charge. This is based on the average across England, Scotland and Wales and includes VAT - Standard variable tariff (default tariff) and pay for your electricity by Direct Debit
