Haier WT100V-NCA5 Buffer Tank, 100 L

The Haier WT100V-NCA5 is a 100-litre buffer tank for heating systems with air-to-water heat pumps. It increases the water volume in the heating circuit, providing an additional reserve. This can help the system operate more steadily and reduce how often the heat pump compressor starts and stops. Fewer cycles can help lower the strain on the equipment.

The tank can also provide hydraulic separation between the heat pump and the heating circuits. This is useful in systems with several circuits, such as radiators and underfloor heating. The buffer tank helps coordinate water circulation and supports heating performance as the heat demand changes.

Energy efficiency and splash protection

The model features 50 mm thick thermal insulation, which helps reduce heat loss while storing heated water. Retaining heat helps the system use the energy it produces more efficiently. The IPX4 protection rating provides protection against splashing water and allows installation in technical rooms with higher humidity when installation requirements are followed.

The floor-standing design does not require special wall brackets. The tank is installed on a level, stable surface that can support its weight when full. When planning the location, allow enough space for pipe connections and future maintenance.

Compatibility and intended use

The Haier WT100V-NCA5 is designed for heating systems with air-to-water heat pumps. Depending on the system design, it may also be used with other low-temperature heat sources, such as gas or electric boilers. The final connection scheme depends on the equipment characteristics and the heating circuit parameters.

This is a buffer tank for heating-system water, not a domestic hot water storage heater. It is not designed for direct connection to the drinking water supply. Before purchasing, check that the 100-litre capacity is suitable for the system and that the operating pressure meets the manufacturer’s requirements.

Connection and commissioning

The tank is installed on a prepared floor base and connected to the heat pump and heating circuits according to the hydraulic diagram. The system is then filled with heating water, air is removed and the connections are checked for leaks at operating pressure. After installation, the heat pump settings are adjusted to account for the additional water volume. Professional installation is recommended to ensure the system operates correctly.

Why choose the WT100V-NCA5

The 100-litre Haier buffer tank is suitable for systems that need a greater volume of heating water and stable heating performance. It can reduce compressor start-stop cycles and separate heating circuits, while 50 mm thick insulation helps limit heat loss. Floor-standing installation and IPX4 protection make this model a practical option for a boiler room or utility space in a private home.
