A flange is a device that limits the amount of air entering a pump from the hot water cylinder. When water is heated or replaced within the cylinder, air bubbles are formed around the top or side of the cylinder. A Cylinder flange stops these air bubbles from entering the pump. We stock a range of flanges, as well as immersion heater thermostats.
