Panasonic Aquarea WH-WXG20ME8 20kW T-CAP M Series R290 Stand Alone Air Source Heat Pump – Three Phase, 75°C Flow
Hurry up, only 10 items left in stock.
The Panasonic Aquarea WH-WXG20ME8 is a 20kW three-phase stand-alone air-to-water heat pump from the T-CAP M Series, using natural R290 refrigerant to deliver flow temperatures up to 75°C – a direct replacement for gas and oil boilers on existing radiator systems and, in this Big Aquarea size, for multi-family and commercial buildings.
The M Series spans 9–30kW and can be cascaded up to 300kW, so it suits everything from a large family home to multi-family and commercial buildings. T-CAP technology holds full heating capacity at -20°C without an electric heater, operation continues down to -28°C, and 55°C hot water is available even at -28°C. A Panasonic R290 scroll compressor, Bluefin-protected heat exchanger and super-quiet operation underpin its reliability.
Award-winning design (Red Dot and iF 2023) in sleek anthracite grey blends into the architecture. An internet adapter for LAN and Wi-Fi is included, giving Comfort Cloud smartphone control and Aquarea Service Cloud remote maintenance; the unit is smart-grid ready, BMS compatible and can run two independent zones with the optional remote controller. Install it as a stand-alone outdoor unit or combine with a WH-CME control module for extended functionality.

Specifications
Compact and lightweight design
With a low weight of just 21 kg, this ventilation unit can be installed quickly and safely by a single installer. Its space-saving footprint makes the DucoBox Energy Comfort perfectly suited for small plant rooms and confined technical areas.
Software-controlled left/right configuration
The unit is designed for maximum installation flexibility. Left- or right-hand airflow orientation is adjusted entirely via software, eliminating the need for mechanical modifications. This is made possible by an innovative patented double bypass system.
Automatic calibration
Using constant pressure calibration technology, the AUTO calibration function reduces commissioning time by up to 50%. In real-world installations, this can translate into lower labour costs and faster system setup.
High energy efficiency
Advanced dynamic air filtration ensures consistently high heat recovery efficiency. When combined with optional intelligent demand control based on CO₂ and humidity sensors, the system delivers excellent indoor air quality while minimising energy consumption.
Smart copy function for fast commissioning
An integrated software-level copy feature allows installers to duplicate settings and parameters from one unit to another. This is especially valuable for multi-unit or repeated housing projects, ensuring consistent performance and significantly reducing setup time.
