A reliable, self‑cleaning solution for Worcester Bosch heating systems – the 1/2″ Brass Auto Air Vent with Check Valve. Designed to sit quietly in your central‑heating loop, this vent automatically releases trapped air, keeping water flow smooth and preventing noisy “air‑pumping” that can reduce efficiency. The integrated check valve stops back‑flow, while a convenient shut‑off cap lets you pause venting when you need to service the system.
