Aquarea All in One

Aquarea All in One is Panasonic’s indoor package combining hydraulic equipment, controls and a domestic-hot-water cylinder. It is not an outdoor heat-pump family and does not establish the refrigerant or heating output without the paired outdoor code.

Current generations and cylinder sizes

The current M Series T-CAP range has R290 outdoor units and All in One options with 120, 185 and 260 litre cylinders. The detailed 185 litre page lists 9, 12 and 16 kW outdoor-unit pairings across single-phase and three-phase forms. It also identifies different indoor codes and an impressed-current-anode variant.

Panasonic’s K Generation All in One launch material describes a 185 litre stainless-steel cylinder and a 598 × 600 mm footprint. K Series uses R32 refrigerant pipework between the outdoor and indoor units.

L Series All in One combinations use R290 outdoor units and a hydraulic water connection. Current MCS records pair 5, 7 and 9 kW WH-WDG outdoor units with WH-ADC0509L3E5UK indoor units.

The indoor and outdoor codes both matter

All in One cylinder capacity is separate from heat-pump output. The domestic-hot-water calculation establishes the storage requirement, while the heating design establishes the outdoor-unit capacity. Backup-heater power, electrical supply and anode arrangement are also code-specific.

The refrigerant safety boundary follows the generation. M and L contain R290 in the outdoor unit and connect hydraulically. K carries R32 between the outdoor and All in One indoor unit. One All in One installation manual cannot therefore be used for every generation.

Certification record

Current exact M, L and K All in One combinations were present in the MCS Product Directory on 23 July 2026. The record names the relevant outdoor and indoor products; a cylinder-family description is not enough to establish the certified combination.
