Haier WT60V-NCA5 Buffer Tank, 60 L

The Haier WT60V-NCA5 is a 60-litre buffer tank for heating systems with air-to-water heat pumps. It increases the volume of water in the heating circuit and helps the system maintain more stable operation. The additional water volume can reduce how often the compressor starts and stops, lowering the strain caused by frequent operating cycles.

The tank can also provide hydraulic separation between the heat source and the heating circuits. This is useful in systems with radiators, underfloor heating or several circuits with different operating requirements. The buffer tank helps coordinate water circulation and supports more consistent heating performance.

Thermal insulation and moisture protection

The model features 50 mm thick thermal insulation. It helps reduce heat loss while storing heated water and supports the energy efficiency of the heating system. The IPX4 protection rating provides protection against splashing water, so the tank can be installed in technical rooms with higher humidity, provided the manufacturer’s requirements and the system design are followed.

The floor-standing design does not require wall mounting. Installation requires a level, sturdy base that can support the weight of the filled tank. Its compact design makes it suitable for a boiler room or utility space, provided there is enough room for connections and maintenance.

Compatibility and applications

The WT60V-NCA5 is designed for heating systems with air-to-water heat pumps. It may also be considered for low-temperature systems using other heat sources, such as gas or electric boilers, when permitted by the hydraulic design.

The buffer tank is intended for heating-system water and is not designed for direct connection to the drinking water supply. Before choosing a tank, check the system parameters, connection diagram and permitted operating pressure in the equipment documentation.

Installation and commissioning

The tank is installed on a level floor base capable of supporting its weight when full and connected to the heat source 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 specialist should select the connection scheme and carry out the installation.

Why choose the Haier WT60V-NCA5

The 60-litre Haier buffer tank increases the water volume in the heating circuit and supports stable heat pump operation. Its 50 mm insulation helps reduce heat loss, the floor-standing design simplifies placement, and IPX4 protection suits the conditions of a technical room. The WT60V-NCA5 is a practical choice for a private home or another heating system that needs water buffering and hydraulic separation between circuits.
