INTEX 28437EP PureSpa
The Intex PureSpa bubble massage deluxe inflatable spa set is a great option for those looking to have a hot tub experience without the high cost. This 6-person spa is made with an energy efficient cover that helps to maintain the temperature once heated. The spa is also easy to pack away during the summer months to free up patio space.
According to Amazon user Michael Maxey, the spa is a decent working spa for winter, but there are a few drawbacks. The unit took 26 hours to heat the initial tap water fill-up to 102 degrees and once the temperature was 97 degrees, it took about 2 hours to gain each degree thereafter. Heating takes longer than desired, but it is worth noting that it is only a 120-volt unit plugged into a normal wall outlet rather than a 240-volt unit similar to built-in spas.
The control unit has a built-in GFI on the power plug, and the exterior outlet also has one built-in for redundancy. The cover does a great job of insulating the tub and preventing the user’s cat from sinking in/drowning when he jumps on it. The spa also comes with an inflatable disc that sits floating on top of the water full inside diameter of the tub followed by the insulating fabric cover.
One downside is that the unit doesn’t come with a built-in multi-color LED light, but this can be easily added with an aftermarket suction cup light. Additionally, the spa is advertised as being able to seat 6 people, but it may be more comfortable for 2-4 people. The noise level is pretty quiet when just running the heater, but inflating the tub and cover may not be suitable for late in the evening if next-door neighbors are close by.
Overall, the Intex PureSpa bubble massage deluxe inflatable spa set is a great option for those looking to have a hot tub experience without the high cost. However, there are some drawbacks such as the unit taking a long time to heat up and not coming with a built-in light.

Energy Efficient Hot Tubs Buyer’s Guide
An energy efficient hot tub is a hot tub that has been designed to reduce its energy consumption while still providing the same level of comfort. It uses less energy than a traditional hot tub and is usually more cost-effective in the long run. There are a few different technologies that can make a hot tub energy efficient.
Benefits of Energy-Efficient Hot Tubs and Spas
The most obvious benefit of using an energy-efficient hot tub or spa is cost savings. By using less energy, you’ll be able to reduce your monthly electricity bill. Additionally, you’ll also be reducing your carbon footprint, as you’ll be using less energy overall.
Beyond cost savings, energy-efficient hot tubs and spas are also more comfortable to use. Many are designed with insulation materials that help to keep the water at a more consistent temperature, reducing the amount of energy needed to maintain the water temperature. This also helps to reduce energy costs, as the hot tub or spa won’t have to be heated as often.
Factors to Consider When Choosing an Energy Efficient Hot Tub
When choosing an energy efficient hot tub, there are several factors to consider. These include the type of energy technology used, the size of the hot tub, the insulation, and any additional features such as lighting and sound systems.
Types of Energy Technologies Used in Hot Tubs
There are a few different types of energy technologies used in hot tubs. These include solar, geothermal, and heat pump systems. Solar energy is a renewable energy source that utilizes the sun’s rays to heat the water in the hot tub. Geothermal energy is a renewable energy source that uses the natural heat of the earth to heat the water in the hot tub. Heat pump systems use electricity to transfer heat from one area to another.
Size
The size of the hot tub is an important factor to consider when making your purchase. Hot tubs come in a variety of sizes and shapes, so you’ll want to choose a size that fits your needs and budget. If you plan to use the hot tub for multiple people, you’ll want to make sure that it is large enough to accommodate everyone comfortably.
Insulation
A well-insulated hot tub will help keep the water warmer for longer periods of time. This will help reduce energy costs and make the hot tub more energy efficient. Some hot tubs are equipped with special insulation that is designed to keep the water temperature consistent.
Additional Features
Many hot tubs come with additional features such as lighting and sound systems that can add to the experience. Look for features such as LED lighting, built-in speakers, and Bluetooth capabilities, which can help create a more enjoyable environment.
Maintenance
It is important to keep your hot tub well-maintained to ensure that it is running at its most efficient. Regular maintenance of your hot tub will help reduce energy costs, extend its life, and keep it running smoothly.
Cost
The cost of an energy efficient hot tub will vary depending on the model, size, and features. Do some research to find out which models are the most energy efficient and cost-effective.
Conclusion
An energy efficient hot tub can save you money in energy costs while still providing you with the same level of comfort. When choosing an energy efficient hot tub, consider the type of energy technology used, the size of the hot tub, the insulation, and any additional features. Make sure to properly maintain your hot tub in order to keep it running efficiently. Finally, do some research to find out which models are the most energy efficient and cost-effective.
