Panasonic has introduced compact indoor and outdoor units for its Aquarea M Series R290 air-to-water heat pumps, with capacities across the range from 3kW to 9kW. The company says the units suit new builds and retrofits with limited installation space; the 5kW, 7kW and 9kW models are due to join the series in spring 2027.
Panasonic has introduced compact indoor and outdoor units for its Aquarea M Series of residential R290 air-to-water heat pumps, adding options for homes where installation space is limited. The range spans 3kW, 5kW, 7kW and 9kW capacities and is intended for new-build and retrofit projects, according to product details reported by Cooling Post.
The new outdoor unit uses a single fan and measures 996mm high, 1,200mm wide and 430mm deep. It can be connected to Panasonic’s new compact all-in-one indoor unit or used with a bi-bloc system. The outdoor unit can also operate as a standalone solution alongside a control module or remote controller, the report says.
The compact all-in-one indoor unit is 1,427mm high, which is 215mm lower than Panasonic’s existing model. The company’s specifications state that the system can operate at outdoor temperatures as low as -28°C and deliver water temperatures up to 75°C at -10°C. That output may suit some boiler replacement projects using higher-temperature radiators, though a home’s suitability depends on its heating system and heat-loss requirements, as discussed in guidance on heat pump operating costs.
Panasonic lists ratings of up to A+++ at a 35°C flow temperature and says the range provides cooling as well as heating, amid changing federal tax credits for heat pumps. The all-in-one model has an A+ domestic hot water rating and can heat water to 65°C without an electric heater. A 5kW prototype is reported to produce sound pressure levels from 26dB(A) at five metres, with an ErP sound power level of 50dB(A).
Smaller Units Expand Siting Options
The announcement focuses on making air-to-water heat pumps easier to place in homes where plant-room or external space is constrained. A lower indoor unit and a compact, single-fan outdoor unit could broaden the locations installers can assess, including some retrofit properties. Actual installation options will still depend on the building layout, required heating capacity, clearances and local installation rules.
The stated ability to supply water at up to 75°C at -10°C outdoor temperature is relevant to homeowners considering a heat pump while retaining high-temperature radiators. It does not establish that every existing radiator system can work efficiently with the equipment; that depends on design and operating conditions. Panasonic’s stated cooling capability may also be useful in homes designed for compatible low-temperature emitters, such as underfloor heating or smart fan coils.
For installers, the product details emphasize handling and servicing as well as dimensions. The indoor unit has integrated handles and pre-installed rear castors to assist movement, plus front height adjusters intended to help with levelling and pipework alignment. Panasonic says key electrical components are behind a magnetically detachable panel secured with fewer screws.

Aquarea M Series Rollout
The new units are additions to Panasonic’s existing Aquarea M Series, rather than a separate product line. R290 is the refrigerant identified for the range in the source report. Panasonic presents the units for both new construction and retrofit work, with the compact format addressing homes where installation space is restricted.
The product details also describe digital functions. A Cloud Adaptor is included with every indoor unit, connecting to Panasonic’s Comfort Cloud App so homeowners can control heating and hot water remotely and monitor energy use. Installers can use Aquarea Service Cloud for remote system monitoring and maintenance, according to the report.
The announced capacities do not all share the same stated arrival date. Cooling Post reports that the 5kW, 7kW and 9kW models will join the M Series from spring 2027. It does not give a launch date in the supplied material for the 3kW model.

Launch Details Still Pending
The supplied report does not state pricing, country-by-country availability or exact release dates beyond the spring 2027 schedule for the 5kW, 7kW and 9kW models. It also does not clarify when or where the 3kW version will be offered. Further product details may be needed to compare the compact units with other M Series configurations.
The performance figures are presented as product specifications, but the report does not include independent test results, full efficiency tables across operating conditions or installation case studies. The 26dB(A) sound pressure figure refers to a 5kW prototype measured at five metres; it should not be treated as a noise figure for every capacity or site. Homeowners will need property-specific advice on sizing, radiator output and expected running costs.

2027 Models Await Release
The next stated milestone is the addition of the 5kW, 7kW and 9kW units in spring 2027. Panasonic or its distribution partners may provide further information on pricing, sales markets and the 3kW model’s timing before then. Buyers and installers considering the range will need those details, along with project-specific design calculations, to judge availability and suitability.
