Vian Power Nexus Evo 7 EVI
Vian Power Nexus Evo 7 EVI Heat Pump is the flagship model of the range, designed to perform exceptionally in harsh climates. It operates efficiently at temperatures as low as -25°C, maximising heating capacity in extremely low temperatures for reliable performance.
Product Description
Vian Power NEXUS EVO 7 EVI Heat Pump is the flagship model of the range, designed to perform exceptionally in harsh climates. Using Enhanced Vapor Injection (EVI) technology, it delivers a COP of up to 14.2 and operates efficiently at temperatures as low as -25°C, maximising heating capacity in extremely low temperatures for reliable performance.
A high flow rate of 50 litres per minute means it efficiently cycles through the water in your spa, continually warming it. A typical large 8ft square spa contains around 1,500 litres of water, this means the entire volume of water will flow through the heat pump in just 30 minutes.
Whether you’re running a holiday rental, managing a commercial spa facility, or simply want your personal spa ready year-round, the NEXUS EVO 7 provides powerful, efficient heating with intelligent control integration and whisper-quiet operation.
The Nexus Evo 7 EVI can be retrofitted onto most hot tubs by our specialist technician. Some hot tubs come Heat Pump Ready with the required plumbing factory fitted, whereas with others we may need to install new section of pipe systems to integrate the heat pump. If you're not sure whether your hot tub is Heat Pump Ready, contact us and we advise on fitting costs.

Extreme Cold Performance You Can Trust
Most heat pumps struggle or fail completely when temperatures drop below freezing. The NEXUS EVO 7 EVI is different. Thanks to its advanced EVI (Enhanced Vapor Injection) technology combined with WarmCore compressor and tray heating, this heat pump maintains consistent, powerful heating even when ambient temperatures plummet to as low as -25°C.
Exceptional Energy Efficiency = Lower Running Costs
With a Coefficient of Performance (COP) reaching up to 14.2 in optimal conditions, the NEXUS EVO 7 transforms every 1kW of electricity into up to 14.2kW of heating power. Even at 0°C ambient temperature, it maintains a COP of 4.05 – meaning you get 4 times more heat energy than electricity consumed. Over a heating season, this translates to substantial savings compared to traditional electric heaters.
Whisper-Quiet Operation
At just 29 dB(A) at 10 meters, the NEXUS EVO 7 is quieter than a whisper. Anti-vibration rubber feet and a low-profile design further minimise noise and vibration.
Smart Hybrid Logic for Rapid Heat-Up
Need your spa ready quickly? The built-in hybrid logic supports a 3kW direct electric heater override, giving you the flexibility to boost heating speed when needed. This makes it perfect for holiday rentals, commercial operations, or unexpected guests.
Seamless System Integration
The NEXUS Communication System is fully compatible with popular spa control systems from Balboa and Gecko. Use the optional HP-AC006 input switch cable to integrate external controls, allowing your existing spa system to command the heat pump automatically. One less thing to think about.
Built to Last
Premium titanium heat exchanger resists corrosion and scaling, ensuring long-term reliability even with varying water chemistry. IP×4 water protection rating means the unit handles outdoor installation with confidence. Quality Mitsubishi or GMCC rotary compressor delivers years of dependable service.
The Nexus Evo 7 is backed by a 2 year full product warranty, 3 year warranty on the fan, motor and heat exchanger and 5 year warranty on the compressor.
Pair with the Nexus hot tub steps to integrate this heat pump underneath your spa steps without interfering with the heat pumps performance.
