Unvented Cylinder Annual Services


Its just as important to service a unvented cylinder every year as it is a gas boiler.  A unvented cylinder in a bad state of repair can be very dangerous because of the high pressures involved.


During an unvented cylinder service we would check all safety devices to make sure they are operating correctly.  We would also check the expansion vessel to make sure it continues to maintain a equal pressure within the hot water system.
