Product Information

THE MAIN PURPOSE OF THE VESSEL IS TO COMPENSATE FOR THE INCREASE IN VOLUME OF WATER DUE TO THE VARYING WATER TEMPERATURES IN THE SYSTEM, E. Yep - standard reply for unvented - happy to pay a G3 plumber - want to be sure they don't fit the same kit and don't get overcharged. An expansion vessel absorbs the water volume variations in heating systems maintaining constant pressure and help to reduce energy consumption.

The main purpose of the vessel is to compensate for the increase in volume of water due to the varying water temperatures in the system, e.Due to the pressure from the pressurised air surrounding the membrane, water will start to exit the vessel until the membrane is deflated. If water is required by the system, it starts flowing out of the tank without using the pump but just using the pressure in the air cushion. The bracket setup for this one is well dodgy as if it breaks off the wall it will fall on the other pipes and I'll be in a whole lot of trouble!

When it arrived it had all the labels as on the already fitted ARB18 Expansion Vessel (Baxi Megaflow system) .As the process is going on, the membrane deflates until the pressure reaches its minimal threshold value. Then just unscrewing the flexihose from the cylinder and capturing all the water that comes out, then screwing on the new one once it has been compression tested.
