If you have a gas boiler, or are thinking of installing one, it’s important that you know how it works. This will help you to work out if it’s working properly or may have developed a fault.
But information on boilers can sometimes be dense and confusing.
To help you understand your boiler and how it works, we’ve come up with 8 gas boiler terms and definitions you need to know.
A flue is similar to a chimney. It’s a passageway or pipe that provides a route for your boiler’s exhaust gases to move from your boiler to the outside.
As exhaust gases can be a dangerous health and safety risk, it’s important that your flue is secure and ends at a suitable point outside your house.
A condensing boiler uses exhaust gases to heat water and improve its energy efficiency. According to Building Regulations, all boilers installed after 1st April 2005 should be condensing boilers unless there is sufficient reason why not. A Gas Safe registered boiler engineer can inspect your property and let you know if there’s any reason why you can’t install a condensing boiler.
The flow rate is the amount of gas or liquid moving through a channel or pipe over a certain period of time. It’s usually measured in cubic meters per second (m³/s).
Cold water tank
The cold water tank is the part of your boiler installation that stores cold water before it’s heated. Cold water tanks can be fairly big and are part of conventional boiler installations.
Hot water cylinder
A hot water cylinder is the part of a boiler installation that heats water. Hot water cylinders are part of system and conventional boiler installations.
Gas Safety Register
The Gas Safety Register is the UK’s gas safety national watchdog. It’s best to hire a Gas Safe registered engineer if you need any gas work doing in your home.
Carbon monoxide (CO)
Carbon monoxide is a gas that’s produced from the partial combustion of gases like your boiler fuel. It’s colourless and odourless and can be fatal if inhaled in large quantities.
To protect yourself against carbon monoxide exposure you should install a carbon monoxide detector. You should also get all gas appliances, including your boiler, installed and serviced regularly by a Gas Safe registered engineer.
Your energy supplier is the company that supplies electricity or fuels like gas, oil or LPG (liquefied petroleum gas) to your home.
