What is a coal effect gas fire and how does it work?

angela • 24 February 2025

A coal effect gas fire is a modern heating appliance designed to look like a traditional coal-burning fireplace. It gives the cosy appearance of real burning coals but runs on gas instead of solid fuel. These fires offer the charm of a classic fireplace with the convenience of gas heating.


How does coal effect gas fire work?

A coal effect gas fire uses gas burners and ceramic or artificial coals to create a realistic flame effect. Here’s how it works:

  1. Gas supply – The fire is connected to a gas line or a bottled gas source (LPG).
  2. Ignition system – When turned on, the fire ignites using a manual switch, remote control, or automatic ignition system.
  3. Flame simulation – Gas flows through burners hidden beneath ceramic coals. When lit, the flames rise through these coals, making them glow like real burning coal.
  4. Heat output – The fire produces heat, which warms the room. Some models also have fans to distribute heat more efficiently.
  5. Ventilation – Depending on the model, the fire may use a chimney, flue, or balanced venting to remove waste gases safely. Some advanced models are flueless and use a catalytic converter to clean emissions.


Types of coal effect gas fires

There are different types of coal effect gas fires based on ventilation needs:

  • Open-flame gas fires – These require a chimney or flue to vent gases outside.
  • Glass-fronted gas fires – These are sealed with a glass panel, making them more efficient and reducing heat loss.
  • Flueless gas fires – These do not need a chimney. They use a catalytic converter to clean the gases before releasing them into the room.


Benefits of a coal effect gas fire

  • Realistic look – It mimics the charm of a traditional coal fire.
  • Convenient – No need to store coal or clean ashes.
  • Energy efficient – Modern models offer great heat output with low fuel consumption.
  • Safe – Advanced safety features prevent gas leaks and overheating.
  • Easy to use – Can be controlled with a switch or remote.


A coal effect gas fire is a great way to enjoy the warmth and beauty of a traditional fireplace without the hassle of solid fuel. It offers style, efficiency, and ease of use, making it a perfect choice for modern homes.
