• Compatibility with Plunges: What tubs is it compatible with? Are there limitations, or can you use it with a variety of plunge setups?

Best Overall: Active Aqua 1 HP

The Active Aqua 1 HP comes in at best overall because of its durability and versatility. It’s recommended for indoor use, but in my experience, it performs just as well outdoors. I’ve kept mine outside, uncovered, and it has held up with no issues, even in varying weather conditions. If you’re looking for a durable chiller that pairs with almost every plunge tub on the market, this model is worth getting, especially if you have a larger plunge tub of up to 250 gallons.

It weighs about 74 pounds without water, which is about what you can expect for a 1 HP water chiller. One small design feature to keep in mind is that the cord comes from the side, which might affect how you place it in your setup.

In terms of power consumption, this unit pulls 10.2 amps while running, which is on the higher side, but as a result you get super fast cooling (10-15°F/hour on average) and a higher flow rate (up to 3900 gallons per hour). If energy costs are a concern for you, this might be something to consider. Also, it’s only compatible with 1-inch fittings, so you’ll need 1-inch tubing if you plan to use this chiller with your tub.

The chiller is easy to use. It has simple push-button controls and includes a ‘boost’ mode, which cools the water faster. If you’re like me and want to cool the water fast but don’t want to leave it running 24/7 this is a great option. The boost mode can either be set for 2 hours or left on continuously, which I don’t recommend for overall chiller health, but I’ve heard of some plungers doing that without any problems.

In terms of pumps, you can use any inline or submersible pump with this chiller, but personally, I recommend this submersible pump for the best performance. If you’re using a submersible pump, be sure to connect it to a GFCI (Ground Fault Circuit Interrupter) and turn it off before you get into the plunge for safety. This is something I prioritize and it’s crucial for your safety!

The Active Aqua 1 HP chiller can be found on Amazon for around $1,599, along with the pump, tubing, fitting, clamps and filter that you’ll need for setup. It’s what I recommend for anyone serious about cold plunging at the next level.

Best all-weather: Evolve Pro 1 HP

The Plunge Evolve Pro Chiller is a high-end, all-in-one system designed specifically for cold plunge enthusiasts. With a powerful 1 HP chiller, it cools water to 37°F and connects to the Plunge app, allowing you to track sessions, adjust temperatures, and control it remotely. The optional heating component, which can raise water to 104°F, is especially useful for those in colder climates where freezing could damage the chiller.

One standout feature is its efficiency. This chiller cools water 30% faster and operates 30% quieter than the standard model.It’s equipped with a 20-micron filtration system and uses ozone filtration to keep the water clean and bacteria-free. The added benefit of ozone filtration ensures a more hygienic experience, reducing the need for frequent water changes. A variable-speed fan adjusts based on the ambient temperature, ensuring smooth performance even in extreme conditions. Plunge has tested this model in environments up to 120°F to guarantee optimal functionality in heat.

The chiller is easy to use, featuring five intuitive buttons, including a pause function for still-water plunging or filter changes. It weighs 91 pounds, and the handles on either side make moving it more manageable. The design fits Plunge’s signature sleek aesthetic with a slanted acrylic finish and is suitable for both indoor and outdoor use.

One of the most convenient aspects is its integration with the Plunge app, which can diagnose potential issues such as clogged filters, reduced flow rates, or pump malfunctions. This proactive maintenance feature makes it easier to keep your setup in check while saving you time and hassle.

Overall, the Plunge Evolve Pro Chiller is a reliable, efficient, and technologically advanced option for those serious about cold plunging. Though expensive, it’s a worthy investment, particularly if you already own Plunge’s tubs, as using it with another brand voids the warranty. For cold plunge enthusiasts who value convenience and performance, this chiller is hard to beat.

Best design: Ice barrel 1/2 HP

The Ice Barrel Chiller is an advanced cold plunge system that offers innovative features for both energy savings and convenience. One of its standout functions is the scheduling feature, which allows users to save on electricity by setting precise times for the chiller to operate. You can adjust the temperature directly from your phone or the chiller itself, and with multi-user support, each user can set their own schedule. This is perfect for households with multiple cold plungers or wellness centers that serve various clients.

At the heart of the Ice Barrel Chiller is its SmartSense mode, which ensures the system runs efficiently and prepares the water for your session without having to be constantly active. Instead of keeping the chiller running at all times (costing you hundreds), SmartSense uses algorithms to monitor and control the components and cycle the water every 10 minutes to check its temperature, filter it, and calculate what’s needed to keep it ready for use. It even ensures that the water temperature remains within 10°F of your next plunge, so it’s always close to your preferred setting.

The chiller also features a cooling mode, which actively brings the water down to your desired temperature. Whether you use the app for an instant session or follow a pre-set schedule, once the temperature is reached, it enters Ready mode. In this mode, it holds the water temperature for up to 2 hours and sends you a notification when your plunge is ready, which I found very helpful because of my ADHD. You can adjust the ready window according to your needs, allowing for flexibility depending on when you’re planning to use the chiller.

Two additional modes, Maintenance mode and Protect mode, make it easy to maintain and protect the system. Maintenance mode allows you to clean the tub or change the filter, which you can activate via the app or directly on the chiller. Protect mode uses built-in sensors to detect issues with the chiller and sends notifications with recommendations on how to resolve them.

The Ice Barrel Chiller stands out for its user-friendly design and efficiency. The ability to schedule, monitor, and adjust settings remotely while only pulling 6 amps is a major advantage for anyone looking to optimize their cold plunge experience. With features like SmartSense mode and multiple operational settings, it not only conserves energy but also delivers a tailored cold plunge when you’re ready. This makes it an ideal option for anyone serious about cold plunging and wanting a chiller that’s as smart as it is effective.

Best DIY: Active Aqua 1/2 HP

The Active Aqua 1/2 HP stands out as the best DIY option. It’s recommended for indoor use, but, like the 1 HP model, I’ve used mine outside without any problems. If you’re working with a plunge tank that holds up to 172 gallons, this chiller has the power for it. At $939, it’s a more budget-friendly option than some higher-end models but still packs a serious punch.

It’s lighter and easier to handle than other other chillers because it weighs only 49 pounds. Setup was super easy for me but may require some help for others. One thing to keep in mind is that the exhaust releases a fair amount of heat, so leaving at least 12 inches of space behind the unit is important to prevent overheating. The cord comes from the side, similar to other Active Aqua models, so be sure to plan your space around that.

One of the biggest advantages of this model is its low power consumption—only 2.2 amps when running, making it much more energy-efficient compared to its bigger siblings. It won’t raise your electricity bill as much, which is always a plus. Its maximum flow rate is up to 1600 gallons per hour, making it a great option for smaller plunge setups. While the flow rate isn’t as high as the 1 HP model, it’s still enough to get your water moving and cooling efficiently. The chiller can cool water down to 39°F, which is more than enough for most plungers.

In terms of usability, the Active Aqua 1/2 HP is just as simple to operate as the larger models. It’s equipped with intuitive push-button controls, which I really appreciate—no complicated settings or extra features to navigate.

In terms of pumps, you can use any inline or submersible pump with this chiller, but personally, I recommend this submersible pump for the best performance. If you’re using a submersible pump, be sure to connect it to a GFCI (Ground Fault Circuit Interrupter) and turn it off before you get into the plunge for safety. This is something I prioritize and it’s crucial for your safety!

Overall, at $939, the Active Aqua 1/2 HP chiller offers great value for its price. It cools efficiently, consumes less power, and works well for medium-sized plunge setups. If you’re looking for an affordable but effective solution to cold plunge therapy, this model is a strong contender. It’s what I recommend for anyone serious about DIY cold plunging at the next level.

Best budget-friendly: active aqua 1/4 HP

The Active Aqua 1/4 HP Water Chiller is an affordable and compact option for those looking to dive into cold plunging without breaking the bank. Priced at $619, it’s designed to handle smaller setups, with a capacity of 92 gallons, making it ideal for personal use or small cold plunge tubs. Weighing only 28 pounds, it’s one of the lightest chillers on the market, which makes it easy to move and install wherever needed.

With a flow rate of 925 gallons per hour, the Active Aqua 1/4 HP has enough power to keep your water circulating efficiently, which is crucial for maintaining consistent temperatures. Despite its smaller size, it’s still capable of pulling 4.7 amps, so you’ll want to ensure your electrical setup can handle it. One of the key things I noticed was how well this chiller performed in tough conditions. I tested it in a Louisiana summer, using an Ice Pod Pro tub, and it cooled the water down to 42°F. Although I placed it in the shade—it’s still impressive for such a small unit.

This chiller also shines when it comes to ease of use. It’s a straightforward plug-and-play device, with intuitive controls that let you set your desired temperature with just a few button presses. For anyone new to cold plunging or those who want to keep things simple, the Active Aqua 1/4 HP makes setup and maintenance a breeze. You won’t need any special expertise to get it up and running, and its small footprint ensures it won’t dominate your space.

One of the downsides, however, is that this chiller may struggle to keep temperatures as low as larger units in extreme heat or with bigger tubs. While I was able to hit 42°F in Louisiana, this was in the shade, and pushing it to lower temperatures in direct sunlight or with a larger tub might just not happen or possibly even damage the chiller. That said, for smaller setups or those in more temperate climates, this chiller does the job quite well.

In terms of pumps, you can use any inline or submersible pump with this chiller, but personally, I recommend this submersible pump for the best performance. If you’re using a submersible pump, be sure to connect it to a GFCI (Ground Fault Circuit Interrupter) and turn it off before you get into the plunge for safety. This is something I prioritize and it’s crucial for your safety!

In conclusion, the Active Aqua 1/4 HP Chiller is an excellent budget-friendly option for anyone looking to enjoy the benefits of cold plunging without investing in a larger, more comprehensive unit. Its portability, ease of use, and decent cooling power make it perfect for casual plungers or those with smaller tubs. While it may have its limitations in extreme heat or with larger capacities, it’s a solid performer for its price and size.

things to consider before buying

Chiller size

The horsepower of a water chiller affects how quickly it can cool the water and handle large volumes, but higher horsepower doesn’t always mean better performance. It’s more about how well all the chiller’s components—like the compressor, fan, and flow rate—work together to cool efficiently. A 1 HP chiller might cool faster than a 1/2 HP, but if the system isn’t well-balanced, even a high-horsepower chiller can struggle with energy efficiency or maintaining temperature.

Think of it like a car: just because a car has a powerful engine doesn’t mean it’ll perform well if the transmission or tires aren’t suited for the speed. All parts need to work in harmony for optimal results. Similarly, a well-designed chiller with lower horsepower can sometimes outperform a higher horsepower one if the components are better integrated.

Outdoors or Indoors?

Before buying a chiller, consider whether it’s designed for outdoor or indoor use. Outdoor chillers need to withstand extreme weather conditions, while indoor models may require better ventilation. Using the wrong type could shorten its lifespan.

For Residential or Commercial Use?

Chillers designed for commercial use often have more power and durability but come at a higher price. Residential models are generally smaller, more energy-efficient, and easier to install. Choose based on the volume and frequency of use you’ll need.

Is It Easy to Fix?

Some chillers are designed with simple parts that make maintenance and repairs straightforward, while others may require professional help from the manufacturer. If you’re not handy or don’t want to deal with repairs, choosing a model with accessible parts is key.

How’s the Warranty?

The warranty is essential for peace of mind, especially for expensive chillers. Check how long the coverage lasts and what it includes. Some warranties may void if you use the chiller with a different brand’s tub or make modifications.

Amps

Pay attention to how many amps the chiller pulls. Higher amps can lead to higher electricity costs, and you need to ensure your electrical system can handle it. Low-amp models tend to be more energy-efficient but may cool slower.

Does It Include Everything I Need?

Some chillers come with all the necessary components like tubing, fittings, and pumps, while others require additional purchases. Make sure you know what’s included to avoid surprises and extra costs.

Summary

Brr-illiant! You’re now armed with all the cool knowledge you need to choose the perfect water chiller for your cold plunging adventures.

Whether you’re a budget-conscious beginner or a seasoned pro looking for top-of-the-line gear, there’s a chiller out there with your name on it.

FAQS

Where do I buy Replacement filters?

Most companies have replacements you can buy directly from their website. If they don’t then amazon or your local hardware store will definitely have the filter you need.

Can I Use my chiller outside?

It depends on the company. Some companies like plunge make chillers that are designed to be used in a range of conditions including extreme heat and freezing cold climates while other companies chillers are meant for indoor use only. As a general rule of thumb I recommend keeping your chiller out of direct sunlight and under a cover.
