The Ideal 174894 Air Vent (Pump) is a genuine replacement automatic air vent valve designed for use with compatible Ideal boilers and their circulation pump assemblies. It helps remove unwanted trapped air from the heating system, improving circulation efficiency and reducing noise.

Function & Purpose

Trapped air in a central heating system can cause noisy operation, poor circulation, and uneven heat delivery. The pump air vent automatically releases small amounts of air that collect in the system without the need for manual bleeding. This supports smoother water flow, reduces pressure issues, and helps maintain efficient boiler performance.

Compatibility

This air vent is engineered to match original equipment specifications for compatible Ideal boiler models that use the 174894 pump air vent. It is designed for correct fitment and reliable performance when installed in the appropriate system.

Build Quality

As an authentic Ideal spare part, the 174894 Air Vent (Pump) is manufactured to high quality standards. The materials and construction are chosen for durability and long-term reliability under the pressures and temperatures typical of boiler circulation systems.

Ideal Applications

This air vent is ideal for heating engineers, service technicians, and installers performing maintenance, servicing, or replacements on compatible Ideal boilers and pump circuits. It is particularly useful when air buildup is causing noise, poor circulation, or cold spots in radiators, helping to restore smooth, efficient, and quiet heating system operation.
