Inverter air-water heat pump Crystal Aqua Aura II 19S All-In-One 250, three-phase
The compact solution for heating, cooling and domestic hot water in one product with an integrated 250 litre DHW boiler.
Key Benefits of the Crystal Aqua Aura II All-In-One Heat Pump
The built-in DHW boiler, with a capacity of 250 L and an enlarged coil, is heated by the heat pump via the built-in 3-way valve, which redirects the entire water flow and power of the heat pump for maximum efficient and fast heating of hot water for sanitary and domestic use. In case of need, the built-in electric instantaneous heater is also activated with a maximum output of 9 kW, which can be limited to 3 kw or 6 kW depending on the characteristics and needs of the specific site.

Solution to save space and money
With its 600mm wide pitch and 710mm deep base, the All in One indoor unit is designed to be installed in standard kitchen units or laundry niches, so you save both space and money on every square metre of RZP.
Easy access and service
The concept of access to all hydraulic and electrical components in the internal body, through quick and easy removal of the front panel, saves time in installation, commissioning and service.
Thermostats for emergency operation - in the event of a malfunction in the outdoor unit or the electronics of the indoor unit, independent electronic thermostats allow the emergency and independent activation and control of the built-in electric heaters for both heating and DHW.
50 mm foamed PU insulation - retains heat in the DHW tank for longer, resulting in less frequent switch-ons to maintain temperature and lower energy bills.

Temperature curve control
Users are given the opportunity to adjust the system to meet the requirements in each specific case - variable heat load, different insulation, joinery, etc., by building their own temperature curve.
It is created as an inverse linear relationship between the outdoor temperature (five values) and the outlet water temperature (five values at each set outdoor temperature).
