Fireplace glossary: part one

Here at the Fireplace Warehouse, we know everything there is to know about fires. While we think our website has pretty much all the information you might need when you are buying a new fire, we appreciate some of the terms used might be new to our customers. We have put together a brief glossary of some of the terms you will come across on our site and in our stores to make it easier for you to choose the right fire for you.

Air vent

This is a legal requirement for some types of fires, such as solid fuel fires and gas fires. The air vent provides an air supply and lets your fire operate safely.

Balanced flue gas fire

This type of fire can be installed in a home that does not have a built-in chimney or flue, but has an outside wall that it can be mounted on. These fires are highly efficient and waste very little energy compared with many other fires.

Catalytic converter

This uses a catalyst to clean waste gas emitted from a fire. It ensures your fire runs more cleanly.

Convection heating

This is when warm air particles rise and cool particles fall into warmer areas. The process transfers warm air around your room.


This stands for the Department for Environment, Food and Rural Affairs. You might notice some of our fires and stoves are labelled as DEFRA approved, which means they have been tested and are suitable for use in smoke controlled areas.


You will come across this word a lot in our product labels and descriptions. The more highly efficient a fire or heater is, the less energy and heat it wastes. An efficient model can help you to cut your energy bills and heat your home more effectively.

Electric fire

A fire that runs solely on electricity and does not require gas or solid fuel. They often simply need plugging into a wall socket, making installation extremely simple.

The Fireplace Warehouse stocks only the leading brands of electric fires in our online collection.

Flueless gas fire

This type of fire does not need a flue or chimney; instead, the gas passes through a catalytic converter. You will need to check the minimum room size for this type of fire, as it will need a certain amount of space and ventilation.

Gas Safe

The Gas Safe Register is the UK's official body for gas registration. You should make sure anyone you hire to install, maintain, check or remove a gas fire or any other gas appliance is on the Gas Safe Register.
