Make your hot tub feel like a routine — not a running-cost debate. The Inverboost UX range is designed specifically for above-ground hot tubs and swim spas, delivering efficient, reliable heat with a quieter, smoother day-to-day experience.
The UX uses air-source technology to extract heat from the outside air and transfer it to your water. Paired with an inverter-driven design, it’s built to modulate output intelligently for consistent temperatures, lower energy use during maintenance heating, and reduced noise compared with basic on/off systems.
Designed to be easy to live with: the UX range is positioned as ultra-silent, with a weather- and UV-resistant casing and an innovative back-discharge design. Choose your kW option based on your water volume, insulation and how quickly you want the system to recover temperature after use.
Efficiency highlight: the UX range is listed with a maximum COP of 16 (manufacturer claim) — aiming to deliver more heat per unit of electricity.
