Combo Tanks - Panasonic Aquarea WH-ADC0309J3E5 Planning And Installation Manual

Product Description

4.8.3 Combo Tanks

The Combo Tanks are modern high-performance tanks, which were developed especially for the
requirements of the Aquarea heat pumps. They are a combination of a larger domestic hot water
tank located in the upper area of the tank and a smaller buffer tank located in the lower area. This
makes the Combo Tanks an ideal solution to supply a household with domestic hot water and
heating for radiators or underfloor heating. These compact models ensure very low standby losses
and quick assembly due to the pre-installed assembly groups such as 3-way valve or electric tank
heater (with safety thermostat and error signal contact)
The use of a Combo Tank helps implement multiple functions efficiently and easily, such as:
Panasonic offers one enamelled Combo Tank (PAW-TD20B8E3-2) and one stainless steel Combo
Tank (PAW-TD23B6E5).
