Quiet efficiency that makes spa ownership easier. The Inverboost PBS range is designed to deliver a premium balance of performance + silence for hot tubs and swim spas. If you keep your water warm and use your spa regularly, a heat pump is one of the most meaningful upgrades you can make for comfort and long-term running costs.
The PBS uses a full inverter solution to modulate output more intelligently. Instead of aggressively cycling on/off, it adjusts to demand — helping maintain temperature more smoothly, with lower noise and improved energy efficiency during “maintenance” heating.
Built for extended season use. The range is listed with operation down to -12°C ambient and a super quiet operating profile, so you can keep your tub at temperature without the garden sounding like a machine room.
Optional Wi‑Fi adds modern convenience if you want easier access and control. Choose the kW size that suits your water volume and how quickly you want to recover temperature after use.
