Take the plunge with Redwood Outdoors! This deluxe heater + chiller system has you covered for both cold therapy and intentional heat exposure. The system comes prebuilt and ready for use, all you need to do is plug it in. The system operates off of household 110V / 60Hz electricity and can be plugged into any standard US outlet. Inside the metal casing, the integrated pumps and chiller / heater deliver hot or cold water directly to your tub. The whole system is operated by a digital control that you can adjust with a simple touchscreen display. Set the temperature to your preferred level and hop in!

The system comes with two threaded hoses which take the water to and from your plunge tub. You can use this system with any tub by either securing the threaded hoses onto the sides of the tub (if your tub has threaded connections) or by simply submerging the hoses in your tub. When cooling, the integrated pumps will then feed the water through the chiller and back into your tub at temperatures as low as 37F. When heating, the integrated pumps will then feed the water through the heating unit and back into your tub at temperatures as high as 104F.

Comprehensive Health Benefits From Cold Therapy

Cold therapy has been shown to provide a large range of health benefits. By implementing cold therapy into your routine, you can lead a happier and healthier life. See for yourself why athletes and fitness gurus around the world are using cold therapy to perform at their peak.

Faster Recovery - Cold shocks decrease pain and reduce inflammation, so you can bounce back faster from hard training sessions or intense competitions.

Boosted Immune System - Cold exposure boosts T-cell counts, promoting a stronger immune system to fight off diseases.

Improved Mental Health - Regular cold therapy leads to better sleep. Sleep is a key factor in your mental performance and mood.

Relieves Stress - Reduced cortisol levels and increased dopamine levels after plunges mean you feel happier and lower stress.

High Power Cooling To Simplify Your Cold Therapy Routine

This unit packs a powerful punch! With a rated cooling power of 1 HP, this chiller can take your water down to 37F, cold enough to make even Wim Hoff shiver! This chiller takes the complexity out of cold plunging, with a simple all-in-one design, all you need to do is plug it in. The system can be used indoors or outdoors and runs off regular household electricity. No more bags of ice or complex piping systems!

Integrated Heating Unit

With an integrated heater, this deluxe system can also heat your water up to 104F. After you finish your cold plunge, turn your tub into a warm bath to take your relaxation to the next level! The heating unit doubles as a freeze control device, keeping you plunge tub safe in below freezing weather.

In most cases, the chiller’s heating efficiency will start dropping when the air temperature is 40F or below, and longer than normal heat-up times should be expected. However, if you are in a drier area (i.e., <60% RH), you will be able to operate in colder conditions without a performance impact. In very humid areas (i.e., >80% RH), heating performance will start dropping before 40F.

Our tubs are not designed to hold high temperatures in harsh winter conditions, and in freezing conditions of 25F and below, your tub may not reach your desired set temperature.

The chiller is not designed for use in <5F as the chiller’s lubricating oil may freeze and cause the machine to seize.

Digital Display And Wi-Fi Enabled

The system is operated by a simple digital display on the top of the chiller unit. Set your temperature and let the tub do the rest.

The system can connect to a smartphone app and can be fully remote-controlled. Set your plunge temperature from the office and have the tub at temperature ready for you to plunge when you get home.

Portable And Universally Compatible

The system is compact and can be easily packed up and taken to your next competition or race. If you already have an ice-cooled plunge tub, you can easily add this electric deluxe heater + chiller to take your routine to the next level. Connect the system to your plunge tub via the threaded hoses or if your tub doesn't have threaded connections, place the ends of the hose directly into the tub's water. Once the intake hose is submerged, it'll start pumping!

Easy Self-Assembly And Operation

No complicated plumbing or wiring is required! Simply hook up the hoses, attach the filter, and plug it in. Once plugged in, the chiller does the rest of the work. The integrated vacuum pump clears any air from the lines and the high-powered condenser will feed you hot or cold water direct to your plunge tub.

Shipping Across The USA

We ship our chillers to everywhere in the United States to cold plunge enthusiasts who enjoy the wellness benefits of cold therapy!
