Electric Chiller & Heater Box for Hot Tubs and Ice Baths, 5kW & 7kW

This energy-efficient dual-action system provides powerful heating for winter and refreshing cooling for hot summer days. Available in 5kW and 7kW capacities, it significantly cuts energy bills while maintaining the perfect hot tub temperature 365 days a year, with or without a wood-fired stove. A chiller enhances the benefits of cold-water therapy by promoting better blood circulation, helping reduce arterial hypertension, strengthening the immune system, accelerating muscle recovery and relaxation, and contributing to lower stress levels. Dual Function Heating and Cooling One compact unit gives you the best of both worlds. Switch between Heating, Cooling, and Auto modes to take your tub from a soothing 40°C soak down to a bracing 2°C cold plunge, all from a single digital control panel. Powerful, Efficient Performance With a rotary compressor and a titanium coil heat exchanger, both the 5kW and 7kW units deliver reliable, efficient temperature control even in larger tubs, helping maintain your ideal temperature year round while keeping running costs sensible. Simple Digital Controls An easy-to-use digital display lets you set your exact desired temperature, switch between Heating, Cooling, and Auto modes, and monitor performance at a glance. Quiet, Compact and Durable Design With sound pressure levels as low as under 50 dBA at 1m, these units run quietly alongside your hot tub or sauna setup. The IPX4-rated, weather-resistant housing is built for reliable outdoor use without taking up much space. Year-Round Cold Therapy Benefits The chiller function turns your hot tub into an effective cold-water therapy tool, promoting better blood circulation, helping reduce arterial hypertension, strengthening the immune system, and accelerating muscle recovery and relaxation, all contributing to lower stress levels.
