Beachcomber is the benchmark in our industry of over 300 brands. The California Energy Commission (CEC) has shown that we are the world's leader in energy efficient hot tubs.

The Toughest Test


The cost to operate varies significantly with influences like the amount of use the hot tub gets, the ambient temperature outside, the temperature you keep your water, the time of year and other factors.

Beachcomber hot tub energy costs were calculated based on:

Data collected while performing energy efficiency testing according to procedures outlined in Title 20 by the California Energy Commission, at ambient air temperatures of 60F/15.6C and water temperatures of 102F/38.9C and

Estimated hot tub usage of 15 minutes with jets on and 15 minutes with jets off, with the cover off, every other day.

The empty hot tub or spa cavity has no insulating properties on its own. Just like the walls of your home, insulation is needed to prevent the transfer of heat out of the vessel. Beachcomber uses a fully expanding foam that is blown in, to expand into every crevice inside the cavity. After it dries, it cures and hardens, making the hot tub into an integrated unit to keep the heat inside.

Many hot tub and spa manufacturers have differing opinions on the best method of hot tub insulation. Beachcomber employs Cavity Fill Insulation to ensure every square inch of a hot tub is fully insulated with foam. Independent reports support Beachcomber’s Eco-design methods by stating that “For purposes of efficiency, more insulation is better”. Cavity Fill Insulation is of the key Eco-Design features that make a Beachcomber Hot Tub one of the most energy efficient in the industry.


Air Cavity Insulation is when some manufacturers employ very little or no insulation between the hot tub shell and cabinetry, leaving the cavity empty with air. There is a common misconception that this Air Cavity provides better insulation than foam.

While it is true that stagnant air when trapped in an air-tight area acts as a good insulator, large volumes of air, such as those inside a hot tub cavity, are never stagnant and impractical to make air-tight.

Let’s take a dual-pane window as a perfect example. Dual-pane windows take advantage of the excellent insulative properties of the gas, Argon, by trapping it in between two panes of glass. You will see that the air-tight gap in between the glass panes is never much larger than about 1 cm. This is because as the gap or volume of air gets larger, air will move more and no longer be stagnant. In fact, moving air loses all insulative properties. Thus, Air Cavity Insulation for hot tub construction is an ineffective insulation technique.


Every Beachcomber Hot Tub runs on a 240 Volt, 60 hertz service in North America. Our Energy Saver Management Systems are fully electric, and are powered by state-of-the-art digital technology. We do offer a 120 Volt service on selected models at participating stores and online at Check with your local building codes for more information on electrical requirements in your city or town.


A hot tub motor runs for a few main reason:

To filter the hot tub water at pre-set filtration cycles.

When you turn on the jet pumps through the digital control pad for massage therapy

To cycle water through the heater to heat water back up to set temperature.

Default filtration cycles can be changed and tailored on the digital control pad to match your lifestyle and your needs. Filtration cycles can be set to a number of times a day and to filter a certain time period. In fact, there are functions such as Economy mode that can be selected for further energy efficiency. Heating cycles will initiate only when hot tub water temperature drops below a certain threshold below the set temperature. Jet pumps will turn on when you use your hot tub and turn on the jets.


All hot tubs in compliance with California Energy Commission’s Energy Efficiency regulations are listed on the Appliance Efficiency Database, which is available for public access.

Using the data obtained from the database, each Beachcomber model was compared to the average wattage listed of competitor models within 15 US Gallons of the Beachcomber model used in the comparison. Our Beachcomber models beat similar volume models from other brands by up to 33%.


Hot tub energy consumption can be attributed to three main hot tub functions:

Heating and maintaining water temperature - 70-75% of Total Hot Tub Energy Consumption

Filtering water - 20-25% of Total Hot Tub Energy Consumption

Other, such as auxiliary lighting, etc. - 0-5% of Total Hot Tub Energy Consumption

Majority of energy consumed in a hot tub is to heat or maintain water temperature. How quickly the water in a hot tub cools is directly influenced by how quickly heat is lost. Beachcomber’s Eco-Design Thermos Construction is designed to maximize energy efficiency in your Beachcomber Hot Tub.

The frequency and duration of filter cycles also have an effect on hot tub energy consumption. Minimizing filter cycle frequency and duration will reduce overall energy consumption. Beachcomber’s Energy Saver Management System allows our customers to have the flexibility to optimize filter cycles, while providing clean, fresh water.


There are 3 specific circumstances in which a hot tub consumes energy and each varies significantly in how it affects energy consumption:

Power Up or Start-up Phase

This phase is when a hot tub is first started up or when a hot tub is drained and refilled with cold water. Energy is consumed to heat the cold water up to the hot tub’s set temperature.

Standby Phase

A hot tub is typically in this phase approximately 75% of its lifetime. Standby phase is when the hot tub is not in use and the cover is affixed firmly to the hot tub. Energy is consumed to maintain the hot tub’s set temperature and operate filter cycles.

Usage Phase

This phase is when the hot tub is being used, with the cover off and jets operating. Energy is consumed:

To maintain water temperature, as there is a large amount of heat lost through the surface of the water.

To operate the jet pumps for a proper massage.


Water Temperature & Ambient Air Temperature

Heat is always lost from a hot to a cold environment. In the case of a hot tub, heat is lost from the hot tub water to the cool air in the environment. A higher water temperature or a cooler air temperature results in more energy consumed.

The only way to reduce the effect temperature has on energy consumption is to maximize the insulation Beachcomber Eco-Design Thermos Construction were Eco-designed and constructed to do exactly this – insulate, conserve energy and save money!

Hot Tub Construction

Picture a cup of coffee in a mug compared to a cup of coffee inside a thermos on your kitchen table. Why does coffee in the mug get cold so much faster than the coffee in the thermos? One reason – Insulation.

Beachcomber’s Eco-Design Thermos Construction provides maximum insulation of the hot water from any cold environment. This reduces the effect of cold temperatures on energy consumption and makes a Beachcomber one of the most energy efficient hot tubs in all climates.

Frequency of Usage

Using a hot tub notably increases energy consumption because of the increased heat loss through the surface of the water when the cover is off. The “steam” you see evaporating into the air on the surface of the water is heat being released into the atmosphere. To optimize energy consumption even during Usage, Beachcomber’s Eco-Design feature, ESMS Technology, uses the most energy efficient pumps and heating technology.


Starting up your Beachcomber Spa after an initial fill with cold water will take most of the heating process. After the hot tub is heated to temperature, the normal circulation mode will maintain the temperature. After this, the hot tub cover is a big factor in efficiency, as heat loss occurs from the water surface. That’s why a Power Guard Heatshield Cover is critical to trap in heat. Our covers feature a vacuum seal to the lip of the hot tub.


The power to run a Beachcomber hot tubs costs less than a dollar a day. Every Beachcomber Hot Tub is Eco-Designed with energy efficiency as a main priority. Building a water vessel to encapsulate heat is our goal. Hot tub construction must use a maximum efficiency heating and pumping system to create the perfect heat-retaining ‘thermos’ style of environment while the hot tub is not in use.

Then when you're ready, your hot tub is ready. We believe in conserving energy so you can relax and enjoy all the health benefits a Beachcomber has to offer. Plus, conserving energy saves you money on your monthly power bill.



Shopping for a hot tub or spa can be a confusing experience, because there are so many conflicting messages surrounding energy and energy efficiency. Ask your local Beachcomber store for the Energy Guide to see the proven running costs based on testing parameters on the specific hot tub you are looking at. Beachcomber’s engineers test our hot tubs on an ongoing basis, analyzing every feature to continue to innovate and enhance energy efficiency.
