With the launch of the latest Aquarea J Generation heat pump, Panasonic says it has delivered its most efficient model to date. Suitable for both residential and commercial applications, the new range features an improved heating efficiency compared with the previous generation, with a CoP of 5.33 on the WH-UD03JE5 model and a domestic hot water CoP of up to 3.3. From September 2019, models will be rated A+++ in low temperature operation, which is the highest energy class according to the new Energy Labelling Directive.
Aquarea uses R32 refrigerant, which boasts a low global warming potential, helping to lower the carbon footprint of a building.
The unit delivers improved comfort even in extremely low temperatures, down to -20˚C. There are two new sensor positions available for DHW control, which can be selected to improve efficiency or comfort levels. Users can select an option for improved efficiency and the most effective DHW CoP when operating in part load capacity, or for greater comfort, simply select an option to reduce heat-up time when operating in full load.
