Q Do I need to be qualified to fit an unvented cylinder ?

You must notify your local building control department that you are installing an unvented system before doing so. This is due to the possibility that the property will require the installation of valves and pipework for pressure relief that will vent outside the structure.

Q How long does it take to install an unvented cylinder ?

A. An increasingly typical substitute for the standard hot water cylinder installation is to install an unvented hot water cylinder in your home. Its greater efficiency for larger homes with higher hot water demands is the primary factor in its appeal. The cold water supply is drawn straight from the mains when installing an unvented hot water cylinder. This indicates that a gravity-fed tank or a connection to a pump is not required. The installation of the hot water cylinder itself will typically take a single day or more. The property might be without heating and hot water until the system is finished, but the system could take much longer. Hot water cylinder units, radiators, pumps, valves, tanks, controls, and electrical connections make up a heating system. If you are installing a new boiler in the same position as your old one or replacing it, it should only take a couple of days. It could take more days if your equipment developed during the removal or installation. Your engineer will go over your alternatives and let you know what you can do if this occurs.

Q What does an unvented hot water cylinder installation cost ?

A. Installation costs for unvented cylinders can range from £550 to over £2000.

First, it will be necessary to evaluate the dynamic pressure test, water pressure, and water flow rates. It will bring about more considerable expenses.
