Introducing Panasonic’s Pioneering Aquarea A2W K and L Generation Heat Pumps
Low-carbon solutions The K generation utilises R32 refrigeration, making it an excellent solution for new homes. Meanwhile, the L generation uses the natural refrigerant R290, which has a Global Warming Potential (GWP) of only 3. The redesigned construction of the outdoor units of both generations provides a high level of safety, as the unit is hermetically sealed for easy and flexible installation. Furthermore, the K generation retains a refrigerant link between the outdoor unit and the indoor unit, while the L generation features a hydraulic link. The new Aquarea L Series is designed to maximise the properties of R290 refrigerant, allowing a water outlet temperature up to 75°C even at -10°C outdoors. It is therefore particularly suitable for renovation and collective applications where a high temperature is required for radiators.
Practical benefits Both generations benefit from a reduced noise level, up to -8dB(A) less than previous models, offering more placement possibilities. They also offer an even higher level of performance for greater savings, boasting an improved SCOP of up to 5.12.
A unique design Although there are technical and technological differences between the two new generations of Aquarea units, they share a common design in terms of their indoor units which retain the premium white colour faithful to the Aquarea spirit, ensuring they fit seamlessly into any interior. The internal design of the units also allows for accessibility, practicality, and flexibility for easy installation and maintenance. The outdoor units have been completely redesigned and will suit even the most stylish homes, integrating the best of Panasonic’s technology in a new contemporary and premium anthracite chassis.

iesbaden, Germany, October 3, 2022 – As the global demand for energy-efficient heating and cooling solutions increases, Panasonic is expanding its Aquarea range of air source heat pumps. Speaking during Interclima 2022 in Paris today, Mr Masaharu Michiura, President,
Heating & Ventilation A/C Company, Panasonic Corporation, outlined the company’s strategy for growth and revealed its latest additions to the range, the Aquarea K and L Generations. Available from Spring 2023, the Aquarea K and L generations are the latest innovations to emerge
from Panasonic’s R&D centres and reflect the company’s values through innovation and are in keeping with its vision of creating technologies for a low-carbon society. The new models are focused on improving energy performance and offering a series with natural refrigerant.
Simple connectivity Focusing on improving installer and user experience, the latest generations come with a new remote control supplied as standard, which features intuitive navigation for ease. There is also an optional second remote control available for 2-zone systems. The systems have the ability for smart control and energy consumption monitoring. Aquarea Service Cloud is available for installers and maintenance companies, allowing real-time remote supervision of a fleet of installations for increased customer satisfaction. The installer has access to statistics, history, and system information. Furthermore, for end users, the Aquarea Smart Cloud offers intuitive control of the heat pumps from a smartphone, tablet, or computer, offering remote heating and cooling programming, energy consumption monitoring, and notifies in the event of an anomaly. The Aquarea Smart Cloud now has a dedicated installation space on the front of the unit which allows for easy connectivity. To find out more please visit our website.

trand Hardware is taking the panic out of buying emergency exit solutions by outlining key considerations for specification. It urges customers to put ‘safety first’ – prioritising functionality, quality, and performance at the head of decision-making.
CE marked products for fire and escape doors are a must for architects and specifiers and best practice determines that products comply with Construction Product Regulations. Strand Hardware’s Antipanic Emergency Exit and Panic range meet these requirements. In an emergency or panic situation, they release exit doors by means of a push bar, touch bar or a push pad on outward opening single or double doors. For day-to-day use, doors can be opened from the outside with an outside access device. “When an emergency door can be locked or opened from the outside, it should still be freely released
from inside – maintaining security without compromising its basic panic function,” said Strand Hardware MD Steve Marshall. He urged specifiers to identify suitable solutions by considering:
1.Product range Strand Hardware offers PH (modular push bar/push pad range), PHT (touch bar range), PHTM (motorised touch bar range) options. Selection criteria is provided by the EN standards EN1125 and EN179 and should reflect occupancy levels. Other matters to be considered include creating clear opening requirements, how the door is intended to be used, whether it is fire resisting, the operating environment etc. Aesthetics and budget will also have a place, but these are secondary to the life safety aspect.
2.Door/frame material and design Different strikes are used to suit various door materials and construction. For PVCU doors and frames, a range of profile related strikes are available for which the system manufacturer and profile model is needed. Glass doors require patch fittings to suit the escape device and door construction. Whether the doors are fire-resisting and how the door is hung will also have a bearing.
3.Locking latch arrangement and number Single and three-point locking latches are available across all the ranges with the ability to convert on site from three point to two point in the most cases. Factors to be considered include whether the door is single or double, construction, material and size. For double doors requiring escape through both leaves, it is critical that whichever door leaf is operated it must open and whether the doors are rebated through the lock stile section/overlapping plates or are plain edged.
4.Outside access External access can be provided by a mechanical outside access device, using a key, push button digital
combination and in most cases either a lever handle or knob. Again, thought needs to be given to how the door is to be used. Most electronic access control can be accommodated by use of an internal motorised touch bar.
5.Size of door Door widths and heights should be checked before ordering as many wider and taller doors can be catered for from stock by use of wider crossbars, wider model touch bars and extra-long rod kits.
6.Finish Powder coated white and black finishes are available from stock along with the standard silver grey, which have the option of a green cross bar. A decorative plated satin stainless steel finish and simulated polished brass are available for many ranges. Where a high degree of corrosion resistance is necessary the DFine grade 316 stainless steel is available. Many other finishes can be provided to special order.
