Haier WT80V-NCA5 Buffer Tank, 80 L

The Haier WT80V-NCA5 is an 80-litre buffer tank for heating systems, including those powered by air-to-water heat pumps. It increases the total water volume in the system and helps maintain a steadier temperature. The additional volume can reduce the frequency of the heat pump compressor’s start-stop cycles, lowering the strain caused by cycling.

The tank can provide hydraulic separation between the heat source and the heating circuits. This is useful when a heat pump needs to work with radiators, underfloor heating or several heating zones. The buffer tank helps separate circulation circuits and supports predictable equipment operation as the heating demand changes.

50 mm insulation and IPX4 protection

The 50 mm thick insulation helps reduce heat loss and maintain the water temperature inside the tank. This supports the energy efficiency of the heating system, particularly when the equipment is located in a separate boiler room or utility space.

The IPX4 protection rating provides protection against splashing water. The model can therefore be installed in a room with higher humidity when the requirements for placement, connection and maintenance are met. Its floor-standing design provides stable installation without wall mounting. Prepare a level base that can support the weight of the filled tank before installation.

Where the WT80V-NCA5 can be used

The Haier WT80V-NCA5 is primarily intended for heating systems with an air-to-water heat pump. Depending on the system design, it can also be used in low-temperature heating systems with a gas or electric boiler if the connection scheme allows it.

The buffer tank is designed for heating-system water. It is not a domestic hot water heater and must not be connected directly to the drinking water supply. Before purchasing, check that an 80-litre capacity matches the heating system calculations and that the operating parameters comply with the equipment documentation.

Installation recommendations

The tank is installed on a prepared floor base and connected to the heat pump and heating circuits according to the hydraulic diagram. After the system is filled, the air must be removed, the connections checked for leaks and the equipment adjusted to account for the additional water volume. A qualified installer should carry out the installation and select the appropriate components.

Benefits of the Haier buffer tank

The 80-litre capacity suits systems that need an additional reserve of heating water and more stable operation of the heating circuit. The Haier WT80V-NCA5 combines 50 mm thick insulation, floor-standing installation and IPX4 protection. It helps provide hydraulic separation, can reduce heat pump cycling and makes the heating system easier to operate.
