Panasonic Heating & Cooling Solutions announced on 22 May 2023 that the All in One units of its Aquarea K Generation heat pump range are now available to the market, in T-CAP and High Performance variants1. The units are air source heat pumps covering heating, cooling and domestic hot water from a single indoor unit1.
The company states the units have a seasonal coefficient of performance (SCOP) of up to 5.12, and that they use R32 refrigerant1. Panasonic says the K Generation retains the refrigerant connection between the indoor and outdoor units and provides water outlet temperatures of up to 60°C even when outdoor temperatures fall to -10°C1. The All in One indoor unit has a footprint of 598 x 600mm, which Panasonic says allows it to be lined up alongside appliances such as a refrigerator or washing machine, and its low height allows a ventilation unit to be installed on top1. Domestic hot water is stored in a 185L stainless steel tank with U-Vacua insulation, which the company says reduces energy losses1.
"Panasonic Heating & Cooling Solutions is pleased to welcome the All in One units, available in T-CAP and High Performance, of its latest Aquarea K Generation heat pumps to market."
The two variants differ in capacity and intended application, as the company sets out1:
| Variant | Capacities | Panasonic's stated application |
|---|---|---|
| T-CAP | 9 to 12kW, single phase | Keeps total capacity even at extremely cold outdoor temperatures; retrofit and new builds; replacing gas or oil boilers; connection to new underfloor heating |
| High Performance | 3.2 to 9kW | New installations and low consumption homes; heating, summer cooling and hot water all year |
Panasonic says the new heat pumps were recognised in the 2022 Good Design Awards, where judges commended the outdoor unit's design for blending into the landscape1. The announcement does not give UK prices, installation costs, grant eligibility or a list of accredited installers, and none of these have been reported1.
Why it matters for households
The headline figure for a household is the SCOP of up to 5.12, which describes how much heat the unit delivers per unit of electricity over a season under standard test conditions1. A higher figure points to lower running costs for a given amount of heat, though real performance depends on the property, the emitter system and the flow temperature the system is set to run at. Panasonic's own description ties the High Performance variant to new installations and low consumption homes, and the T-CAP variant to keeping capacity at very cold outdoor temperatures, which is the condition that most affects whether a heat pump can carry a home's full heating load without back-up1.
The All in One format matters for energy independence in a practical sense: heating, cooling and hot water come from one unit with an integrated 185L cylinder, so a household is not relying on a separate boiler and cylinder arrangement, and the unit's 598 x 600mm footprint is close to that of a large kitchen appliance1. The stated ability to deliver 60°C water at -10°C outdoor temperature is relevant to homes with existing radiators rather than underfloor heating, because higher flow temperatures widen the range of properties a system can serve without changing emitters1. Panasonic's Aquarea range sits alongside other air source options from Vaillant, Grant and Bosch, and the wider heat-pumps hub covers how these systems compare.
What happens next
No UK availability dates beyond the 22 May 2023 market announcement, no pricing and no installer or grant details are given in the announcement1.
