Buying a hot tub involves more than choosing the proper size, shape, or number of jets. For many homeowners, energy efficiency is one of the most important features to consider.
A hot tub is designed to hold warm water year-round, including through cold Idaho evenings, snowy winter months, and changing seasonal temperatures. That means insulation, cover quality, circulation, heater settings, and overall spa design can all affect efficiency.
If you are shopping for an energy-efficient hot tub in 2026, two brands worth considering are Artesian Spas and Nordic Hot Tubs. Both brands offer options designed to help retain heat, support year-round use, and make ownership easier for homeowners.
This guide highlights top energy-efficient hot tub options from Artesian and Nordic. These are not ranked on an official national list. Instead, they are selected based on energy-saving features, spa size, insulation, plug-and-play convenience, and year-round usability.
What Makes a Hot Tub Energy Efficient?
Energy efficiency in a hot tub starts with heat retention. The better a spa holds heat, the less work the heater has to do to maintain your preferred water temperature.
A few key features can affect hot tub efficiency:
- Quality insulation
- A well-fitted spa cover
- Efficient circulation
- Proper cabinet construction
- Water volume
- Heater settings
- Filter and water care maintenance
- Placement away from heavy wind exposure
The Pool & Hot Tub Alliance explains that energy-efficiency standards for portable electric spas include energy labels that identify the manufacturer, model, volume, and energy usage. This helps shoppers compare spa models clearly when reviewing energy performance.
The California Energy Commission also requires portable electric spas manufactured for sale in California to meet standby power performance standards and labeling rules. While requirements vary by state, these standards are helpful because they show why insulation, covers, and tested performance matter when choosing a hot tub.
For homeowners in Idaho, energy efficiency is especially important because hot tubs may be used during both hot summers and cold winters. A well-insulated spa can help maintain heat more consistently, keeping the experience more comfortable and practical year-round.
Why Artesian and Nordic Are Strong Choices
Artesian Spas and Nordic Hot Tubs both offer models with features that support efficient ownership.
Artesian highlights full foam insulation as one of its key energy-efficient features. The company explains that full-foam insulation helps reduce heating costs by limiting air infiltration and helping to keep heat inside the spa. Artesian also notes that its insulation materials do not contain harmful blowing agents such as HFCC, HCFC, HFA, or VOC emissions.
Nordic Hot Tubs uses rigid, closed-cell, 2-pound density foam sprayed onto the outside of the hot tub shell. Nordic also offers Nordic Wrap insulation, which adds an additional R-9.5 layer to the existing foam insulation and helps protect the spa in colder climates. Nordic states that this added insulation helps its hot tubs meet or exceed California Title 20 Appliance Efficiency Regulations.
Both brands offer homeowners choices to meet various needs. Some shoppers may want a smaller plug-and-play model, while others may want a larger family-size spa with more seating. The best energy-efficient hot tub is not always the biggest or the most powerful. It is the one that fits your space, your lifestyle, and your plans for how you will use it.
1. Nordic Retreat All-In-110V
The Nordic Retreat All-In-110V is a strong option for homeowners looking for a plug-and-play spa with energy-efficient features.
This model is part of Nordic’s All-In-110V series, which is designed for the convenience of 110V operation. The Retreat All-In-110V includes a 110V, 15A setup with a GFCI cord, a 1kW heater, and a 250-gallon operating capacity. It also includes foam insulation with Nordic Wrap, making it a straightforward plug-and-play option.
This makes it a good fit for homeowners who want a practical spa without requiring the same electrical setup as a larger 220V hot tub.
Why it stands out:
- Plug-and-play 110V operation
- Nordic Wrap included
- 250-gallon operating capacity
- Compact but roomy enough for up to five adults
- Good option for everyday soaking
The Retreat All-In-110V is a good option for homeowners who want a balance of comfort, simplicity, and energy-friendly design. It is especially appealing to people who want a spa that is easier to install yet still offers the benefits of a permanent hot tub, making it a good option for plug-and-play shoppers.
2. Nordic Crown XL
The Nordic Crown XL is a great option for homeowners who want a larger hot tub while still prioritizing energy efficiency.
This model has a 330-gallon operating capacity, 30 jets, and seating for up to six adults. It runs on 220V and includes foam insulation as standard, with Nordic Wrap available as an optional upgrade. That makes it a larger, more flexible choice than the Retreat All-In-110V.
The Crown XL is also a good example of why energy efficiency is not only about choosing the smallest spa. A larger hot tub can still be a smart choice when it has good insulation, a quality cover, and the right settings.
Why it stands out:
- Seating for up to six adults
- 330-gallon operating capacity
- Foam insulation standard
- Nordic Wrap optional upgrade
- Good family or entertaining option
For homeowners who want room to stretch out, entertain, or use the spa with family, the Crown XL is a strong model to consider. Adding Nordic Wrap can be especially helpful for colder climates or homeowners who want extra heat protection, which is why this model stands out for larger-spa shoppers.
3. Artesian Garden Spas Viola
The Artesian Garden Spas Viola is a compact, efficient option for smaller spaces.
This model is designed for three seats and has a 220-gallon capacity. It uses a 1.5 BHP two-speed 120V pump and is described as compact and efficient. The Viola also includes ArcticPac insulation with an ABS bottom as a standard feature, and Full Foam is listed as an optional feature, giving it a different insulation profile from Nordic’s foam-and-wrap approach.
The Viola is a good fit for homeowners who want a relaxing hot tub experience without needing a large spa. Smaller water capacity can be helpful because there is less water to heat and maintain compared to larger models.
Why it stands out:
- Compact 3-seat layout
- 220-gallon capacity
- 120V operation
- ArcticPac insulation with ABS bottom
- Full Foam optional feature
Â
For couples, smaller households, or homeowners with limited patio space, the Viola offers a practical way to enjoy a hot tub without going oversized, making it a great choice for shoppers prioritizing space-saving efficiency.
4. Artesian Garden Spas Camellia
The Artesian Garden Spas Camellia is another good energy-conscious choice from the Garden Spas line.
This model has four seats, 23 jets, and a 235-gallon capacity. It also uses a 1.5-BHP, two-speed, 120V pump. Artesian lists ArcticPac insulation with an ABS bottom as a standard feature, along with a vinyl cover, digital control system, and ozone-ready design. Full Foam and an All-Seasons Cover are listed as optional features, adding more flexibility.
The Camellia is a nice middle-ground option. It is larger than a two- or three-person spa but still compact enough for many backyard spaces.
Why it stands out:
- 4-seat layout
- 235-gallon capacity
- 120V operation
- ArcticPac insulation with ABS bottom
- Optional Full Foam
- Optional All Seasons Cover
Â
For homeowners who want a smaller spa with room for guests, the Camellia is a strong option. It gives you practical seating without moving into a much larger water capacity, which supports its energy-conscious appeal.
5. Artesian Garden Spas Wisteria
The Artesian Garden Spas Wisteria is a larger option within the Garden Spas line.
This model has seating for six, 27 jets, and a 330-gallon capacity. It also uses a 1.5-BHP, two-speed, 120V pump. Like other Garden Spas models, the Wisteria lists ArcticPac insulation and an ABS bottom as standard features, with Full Foam and an All Seasons Cover available as optional features, giving it a different set of options than Nordic’s wrap-based lineup.
The Wisteria is a good fit for homeowners who want more seating while still staying within the Garden Spas style of compact, plug-and-play-friendly design.
Why it stands out:
- Seating for six
- 330-gallon capacity
- 120V operation
- ArcticPac insulation with ABS bottom
- Optional Full Foam
- Optional All Seasons Cover
The Wisteria works well for families or homeowners who want a social spa without opting for a much larger luxury model, making it a clear choice for those seeking more seating in a compact design
How to Choose the Best Energy-Efficient Hot Tub
When comparing energy-efficient hot tubs, think about how you will actually use the spa.
A couple may not need a large six-person hot tub. A family may want more seating and deeper hydrotherapy options. A homeowner with a smaller patio may prefer a compact plug-and-play model. Someone planning to soak year-round may want to pay extra attention to insulation and cover upgrades.
Before buying, consider:
- How many people will usually use the hot tub?
- Do you want 110V plug-and-play or 220V power?
- Will the spa be used year-round?
- Is the hot tub protected from wind?
- Does the model include upgraded insulation?
- Is an upgraded cover available?
- How often will you use the spa?
- Do you want a compact spa or a larger family model?
A hot tub that is too large for your needs may require more water, more heating, and more maintenance than necessary. On the other hand, a spa that is too small may not provide the comfort or seating you want in the long term.
The best choice is the model that fits your space, lifestyle, and soaking habits.
Tips to Lower Hot Tub Energy Costs
Choosing an energy-efficient hot tub is only part of the equation. How you use and maintain your spa also matters.
To help improve efficiency:
- Keep the cover closed when the spa is not in use.
- Make sure the cover fits properly.
- Replace damaged or waterlogged covers.
- Keep filters clean.
- Use economy or energy-saving settings when appropriate.
- Avoid unnecessary temperature changes.
- Place the spa in a sheltered area when possible.
- Keep water balanced so the system runs properly.
- Schedule regular maintenance.
A good cover is especially important. Heat rises, and a poorly fitted or damaged cover can allow heat to escape. Even a well-insulated spa can lose efficiency if the cover is no longer doing its job.
