Panasonic Heating & Cooling Solutions has launched  the Aquarea Loop, a new decentralised water-to-air heat pump, designed to improve households’ energy efficiency. 

The Aquarea Loop operates with a low-temperature central water loop of 20-30° year-round, providing efficient and sustainable heating and cooling for indoor spaces. 

It features a compact indoor unit, with a depth of 140mm and available in three models.

Its built-in DC inverter compressor and sealed refrigeration circuit both utilise the natural refrigerant R290 to enable the unit to perform as an evaporator in heating mode and a condenser in cooling mode. 

According to the manufacturer, this results in the unit boasting cooling capacities ranging from 1.1 kilowatts (kW) to 3.10kW that can automatically adjust depending on ambient conditions. 

The new heat pump is suitable for both residential and commercial applications, including modern and heritage buildings, hotels and hospitals, and aims to enhance efficiency, while maximising the use of renewable energy. 

It can also be installed re-using existing piping, replacing conventional radiators and substituting the existing heat source with an Aquarea heat pump, making it an ideal solution for many refurbishment projects. 

The heat pump can be supplied with pre-installed hydraulic options, including two-way and three-way motorised valves.

The unit comes with an optional Condensation Injection Kit, which ensures that if it is not possible to pipe away condensation, it can reinject it into the system.

Consumers are able to control the system through a choice of Modbus or Wi-Fi connectivity to enhance usability further, and there is also a choice of on-board or wall mounted systems. The units also come with PI logic control, optimising both comfort and efficiency.
