Advanced inverter heat pump technology that keeps your spa warm and energy bills low.
Heating your hot tub shouldn’t be a drain on your wallet or the environment. InverBoost heat pumps are purpose-built to deliver reliable, whisper-quiet spa heating with exceptional efficiency — even in the unpredictable UK climate.
Unlike conventional systems, InverBoost dynamically adjusts power output to match heating demands, delivering consistent comfort while dramatically lowering energy use.
Whether you use your hot tub daily or just a few times a week, InverBoost ensures you’re only using the energy you need — no more, no less.
Key advantages include:
Up to 70% energy savings compared to traditional electric heaters
Ultra-low noise operation – ideal for quiet gardens and patios
Eco-friendly R32 refrigerant for minimal environmental impact
The UK’s varied climate calls for equipment that can perform in everything from mild drizzle to hard frost. InverBoost is engineered with our seasons in mind.
No matter the season, your spa stays ready, reliable, and inviting.
Energy costs in the UK are rising — but your spa doesn’t have to be part of the problem. InverBoost offers a future-focused alternative to electric-only systems, giving you full heat and full control with a lighter environmental footprint.
