Flotide Inverter 21 Pool Heat Pump 18.4kW | Pools 50-95m³ | R32 Eco-Friendly

High-Output Inverter Heat Pump for Larger Pools

The Flotide Inverter 21 is a serious bit of kit for larger residential and light commercial pools. Built for pools between 50-95m³, it delivers up to 18.4kW of heating capacity with full inverter modulation and a peak COP of 10.0 - so you get powerful heat-up performance and outstanding running-cost efficiency once your pool is up to temperature.

🏷️ Energy Rating: A | 📡 Wi-Fi Module Included | FREE DELIVERY across the UK on all orders.

⚡ Important: Hardwired Installation Required

Unlike our smaller plug-and-play models, the Inverter 21 draws up to 15.72A and needs a dedicated electrical supply with a 20A or 32A circuit breaker, fitted by a qualified electrician. Plan for the electrical install at the same time as the pipework.

🏊 Perfect For

  • Pool Size: 50-95 cubic metres (large residential and light commercial pools)
  • Pool Dimensions: Typically 10m x 5m up to 14m x 6m pools
  • Water Volume: 50,000 - 95,000 litres
  • Applications: Domestic swimming pools, holiday lets, small hotels and wellness centres, chlorine or saltwater systems
  • Note: Maximum pool volume depends on environmental conditions and desired temperature

✨ Key Features & Benefits

Smart Inverter Technology

The full inverter compressor automatically adjusts heating capacity to suit weather conditions. Modulating output from 4.38kW up to 18.4kW means rapid heat-up when you need it and gentle, efficient operation once your target temperature is reached - cutting running costs by up to 30% compared to non-inverter models.

"All Seasons" Operation

Works in ambient temperatures down to -7°C, so you can extend your swimming season well into autumn and start earlier in spring. Automatic defrost keeps the unit running efficiently even in cold snaps.

Automatic Heating & Cooling

Not just a heater - the Inverter 21 can also cool your pool water in the height of summer. Automatic mode maintains your target temperature year-round without manual intervention.

Eco-Friendly R32 Refrigerant

Uses R32 refrigerant, which has a Global Warming Potential (GWP) 3x lower than older R410A gas. Powerful heating performance while doing your bit for the environment.

Outstanding Energy Efficiency

With a COP (Coefficient of Performance) of up to 10.0 at optimal conditions, the Inverter 21 delivers up to £10.00 worth of heat for every £1 of electricity consumed. Even in cooler UK weather (15°C air temperature), it maintains an impressive COP of 6.1.

Titanium Heat Exchanger

The PVC-titanium heat exchanger is built to last, offering superior corrosion resistance for both chlorine and salt chlorinated pools. Reliable, worry-free operation for years to come.

Quiet Operation

Low noise rotary Gree compressor combined with a variable speed fan motor keeps noise levels manageable - 53 dB(A) at full output, dropping to 33 dB(A) in silent mode.

Wi-Fi Control Included

Wi-Fi module supplied as standard - monitor and adjust your pool temperature from anywhere using your smartphone. Glass touch display on the unit for direct control.

SmartGrid Technology

Built-in SmartGrid input lets external signals influence electricity usage - useful for solar PV systems where you can prioritise running the heat pump when self-generated electricity is available.

Durable ABS Cabinet

Robust black ABS plastic cabinet resists UV damage, corrosion and weathering - built to withstand the British climate year after year.
