Wilo Star-Z NOVA T Circulating Pump

The Wilo-Star Z NOVA T circulator pump (reference: 4222650) is an efficient and highly reliable solution, specifically designed for domestic hot water systems in single-family homes. This wet rotor circulator pump is particularly suitable for drinking water applications, providing a consistent and efficient flow of hot water, and helping to maintain an optimal temperature in the DHW (domestic hot water) recirculation system.

Manufactured with a high-quality brass casing, the Wilo-Star Z NOVA T is designed to resist corrosion and offer a long service life in potable water environments. Additionally, the Noryl impeller and ceramic shaft ensure reliable and quiet operation. The bearing material is resin-impregnated carbon, adding durability and smoothness to the pump's daily operation.

One of the main benefits of this pump is its blockage-resistant synchronous motor, which features a high starting torque, meaning the pump can start and operate optimally even in challenging conditions or when higher initial power is required. This ensures the pump runs smoothly over time, reducing the risk of interruptions or breakdowns.

The Wilo-Star Z NOVA T is extremely energy-efficient, with a power consumption of just 6 W, making it a very economical choice for domestic hot water systems. Its energy efficiency is combined with a range of advanced features that make it easy to use and maintain. For example, it comes equipped with an integrated switch clock and temperature control, allowing the pump's operation to be adjusted precisely and automatically, optimising energy consumption based on the actual hot water demand.

A standout feature of this pump is its anti-legionella thermal recognition routine. This system is designed to ensure the water temperature is maintained within a safe range, helping to prevent the proliferation of bacteria such as legionella, which is a risk in poorly managed hot water systems. The pump works in conjunction with the heating system to ensure the water is kept at temperatures that inhibit the development of these bacteria, providing a safer environment for water consumption.

Additionally, the pump includes a standard thermal insulation shell, which helps reduce heat loss and maximise the efficiency of the domestic hot water system. It is also equipped with a non-return valve and a ball shut-off valve with G1 thread, facilitating maintenance and ensuring the system operates efficiently and without hitches.

In terms of operational capacity, the Wilo-Star Z NOVA T supports a maximum working pressure of 10 bar and a fluid temperature range between 2°C and 95°C, making it suitable for a wide range of domestic hot water applications. Its compact design, with a length between threads of 138 mm and G1 pipe connections, allows for easy installation and adaptability to different systems.
