It integrates directly into the hot tub cabinet — hidden beneath the larger step — so there is no external unit cluttering your garden or terrace.\u003c\/p\u003e\n\n\u003cp\u003eThe Smart-In Step heats and cools water between -5 °C and +40 °C, giving you a hot bath in winter and a cooling plunge in summer from the same unit. Compared to the electric heater alone, it reduces heating energy use by approximately 70–75 % (Wellis measurements, California Energy Commission test conditions), which means significantly lower running costs throughout the year.\u003c\/p\u003e\n\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003eHeating\/cooling power: 3 kW\u003c\/li\u003e\n\u003cli\u003eOperating range: -5 °C to +40 °C water temperature\u003c\/li\u003e\n\u003cli\u003eIntegration: built-in under the larger step (no external unit)\u003c\/li\u003e\n\u003cli\u003eCompatibility: Wellis PeakLife hot tubs prepared for the Smart-In Step system\u003c\/li\u003e\n\u003cli\u003eEnergy saving vs. electric heater only: ~70–75 %\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatibility and installation\u003c\/h3\u003e\n\n\u003cp\u003eThe Smart-In Step is designed for Wellis PeakLife models with the factory preparation for this system — the cabinet leaves the factory with space for the heat pump already reserved.
