Panasonic Aquarea 5kW J Generation R32 Monobloc Standalone Heat Pump

Key Features

• 5 kW heating output @ A7/W35 with a COP of 5.08 for excellent efficiency

• Uses R32 refrigerant with lower global warming potential than R410A

• A+++ ErP rating at 35°C and A++ at 55°C for seasonal performance

• Reliable operation from –20°C to +35°C outdoor temperature

• Delivers flow temperatures up to 60°C, suitable for radiators and underfloor heating

• Built-in 3 kW electric back-up heater for legionella cycles and support at peak demand

• Quiet operation with 59 dB(A) sound power at part load and 64 dB(A) at full load (heating)

• Integrated inverter circulation pump and safety components for “plug & play” installation

• Compatible with Panasonic Aquarea Smart Cloud for remote control and monitoring (optional CZ-TAW1)

Installer Benefits

• Monobloc system – only water connections required, no refrigerant pipework or F-Gas certification on site

• Compact footprint (865 × 1,283 × 320 mm, approx. 99 kg) for easier siting on patios, paths or wall brackets

• R 1¼” water connections with variable-speed pump to match a wide range of system designs

• Factory-integrated components minimise on-site wiring and reduce installation time

• Works with cylinders, buffer tanks and accessories from Panasonic’s Aquarea range or third-party components
