When a gas fire is described as highly efficient it simply means that your home can be heated effectively with heat generated immediately. When you have high-efficiency gas fires this often allows you to turn the central heating off when you just need to heat fewer rooms.
What is a high-efficiency gas fire? Find out more here…
Gas fire efficiency can be explained by a calculation that’s used to deduce the efficiency of the fire – the more heat that goes into making a room warmer with minimal waste. High-efficiency ranges of gas fires have been produced to give value for money whilst providing an even greater source of heat.
A Glossary of Terms
Look at a range of terminologies used here to help explain the gas fire workings:
- Catalytic converter – a device incorporated into the fire containing a catalyst for converting pollutant gases into less harmful ones
- Convection – a transfer of heat resulting from the physical movement of hot masses of air
- Emissions – the production and discharge of gases released into the air
- Radiant heat – involves transferring energy from a source that emits heat
Types of High-Efficiency Gas Fires
- Flueless Gas Fires
- Balanced Flue Gas Fires
- Glass Fronted Gas Fires
- Outset Radiant Gas Fires
- Outset Living Flame Gas Fires
Flueless gas fires efficiency can be 100%! You don’t need a chimney or any kind of external flue – any harmful emissions are removed by an in-built catalytic converter. Flueless gas fires have a lower heat rating, but as the efficiency is total all of the heat goes into the room.
This type of fire also benefits from a self-monitoring system that measures air quality – if the quality of the airdrops indicating a potential fault with the catalytic converter the fire switch itself off.
The size of the room is important when considering a flueless gas fire installation as it needs to be about 30cubic metres or larger.
Balanced flue gas fires efficiency can be up to 94%. This type of high-efficiency gas fire comes with its own flue system that exits through an external wall – filtering away any toxic gases. The airflow to the fire is increased by drawing cold air from the room as well as pulling it from the outside.
The heat within the fire is released from a top canopy – and a fuel bed will provide radiant heat. This closed combustion system is the reason why they can provide high levels of heat without depleting oxygen levels in the home.
Efficiency gas fires with a glass front can be mounted on the hearth or built into the wall. They are an extremely efficient way of heating the room as more heat is pushed out through the glass panel. With the aid of radiation and convection techniques less heat is lost up the chimney. High-efficiency glass fronted fires have an 89% net efficiency.
Outset fires sit on the hearth rather than being built into the fireplace wall. These fires use ceramic plates to heat the room with a heat exchanger located at the back of the fire. Convection methods heat the air and they’re extremely effective for heating a room as after being turned off the room can remain warm for a long period of time. And high-efficiency radiant fires produce a net efficiency of 84%.
The living flame style of outset gas fires provides radiant heat through a feature glass front – drawing in cold air to heat and expelling via convection. The living flame effect fire can be installed with a log, cola, or pebble effect bed – and often come with remote control options. A 78% net efficiency is recorded for high-efficiency living flame effect fires.
