New buildings all have mains pressure hot water cylinders – HWC. These cylinders give you the same pressure for your hot water as your cold water. If you have an old building or home you may not yet enjoy the real benefits of mains pressure systems – If your old water cylinder burns out or leaks we recommend installation of a new mains pressure hot water cylinder. Tap leaks can sometimes be repaired, but once your HWC leaks or the heating coil goes it’s usually time for a new unit.
Most new Hot Water Cylinders have good warranty terms so if you do have a failure in a modern HWC unit you may have a warranty claim- so it pays to know when your HWC was installed.
