What is a Gas Fire?

A gas fire is a heating appliance connected to your home's mains gas supply that provides instant, controllable warmth with a beautiful, realistic flame. Modern gas fires are far more efficient than their predecessors — today's high-efficiency models convert over 90% of gas into usable heat, making them one of the most effective ways to heat a room.

At Supply My Fire, we're proud to be a dealer for Wildfire gas fires, known for their exceptional flame quality and contemporary designs. Whether you're after a traditional coal-effect inset fire, a contemporary hole-in-the-wall design, or a glass-fronted balanced flue model, we have the range and expertise to find the perfect gas fire for your home. Visit our Cardiff showroom to see them operating in person.

One of the biggest advantages of a gas fire is the balanced flue option — this means even if your home doesn't have a chimney, we can often still install a gas fire by venting directly through an external wall. This opens up gas fire installation to apartments, modern homes, and properties where a traditional flue isn't available.

Gas fires offer the best of both worlds: the authentic look and feel of a real flame with the convenience of instant on/off control, adjustable heat output, and no ash or mess. Simply press a button or use the remote control and enjoy.

Gas Fire FAQs

Q. Can I have a gas fire without a chimney?

Yes — balanced flue gas fires are specifically designed for homes without a chimney. They use a sealed system that draws air from outside and vents through an external wall. This means we can install a gas fire in most properties, including apartments and modern homes. Our Gas Safe engineers will assess your property during a free home survey.

Q. Is gas fire installation Gas Safe certified?

Yes, every gas fire installation we carry out is completed by our fully qualified Gas Safe registered engineers. Gas Safe registration is a legal requirement for anyone working on gas appliances in the UK, and it ensures your installation meets all current safety regulations. You will receive all relevant certification and documentation upon completion.

Q. How efficient are modern gas fires?

Modern gas fires are far more efficient than older models, with many achieving efficiency ratings of 80% or higher. High-efficiency balanced flue gas fires from brands like Gazco and Wildfire convert the vast majority of gas into usable heat, reducing waste and lowering running costs. Our team can recommend the most efficient model for your home and budget.

Q. How much does a gas fire cost to run?

The running cost of a gas fire depends on the heat output and your gas tariff, but a typical gas fire costs between 20p and 50p per hour to run. This makes gas fires a cost-effective way to heat a single room compared to running your full central heating system. We can provide estimated running costs for any model you are considering.

Q. Can you replace my old gas fire with a new one?

Yes, we regularly replace outdated gas fires with modern, more efficient models across Cardiff, Newport, Swansea, Bristol, and Bath. Our Gas Safe engineers will safely disconnect and remove your old fire, then install and commission your new appliance. Upgrading to a modern gas fire can significantly improve both efficiency and the look of your room.

Q. What's the difference between balanced flue and conventional flue?

A conventional flue gas fire uses your existing chimney or flue to vent combustion gases, making it suitable for homes with a working chimney. A balanced flue is a sealed system that vents directly through an external wall, so no chimney is needed. Balanced flue fires are generally more efficient because they draw combustion air from outside rather than from the room.

Q. How long does gas fire installation take?

Most gas fire installations are completed within a single day. A straightforward replacement of an existing gas fire typically takes three to four hours, while a new installation requiring flue work or building modifications may take a full day. Our team will confirm the expected timeframe during your free home survey.

Q. Do gas fires need servicing?

Yes, gas fires should be serviced annually by a Gas Safe registered engineer to ensure they are operating safely and efficiently. Regular servicing checks for gas leaks, ensures correct combustion, and keeps your fire in peak condition. We offer servicing for all gas fire brands across the Cardiff, Newport, Swansea, Bristol, and Bath areas.

Q. Can I see gas fires working before I buy?

Yes, we have a range of live gas fire displays at our showroom at 112 Whitchurch Road, Cardiff, CF14 3LY. Seeing a gas fire burning in person is the best way to appreciate the flame quality and heat output before making your decision. Call us on 029 2030 9664 to arrange a showroom visit.

Q. What is a Wildfire gas fire?

Wildfire is a premium gas fire brand known for its incredibly realistic flame effects and high-quality build. Their fires feature hand-finished log sets and deep fuel beds that closely replicate the look of a real open fire. We are proud to supply and install the Wildfire range — visit our Cardiff showroom to see them in action.

Q. Can you install a gas fire in an apartment?

Yes, balanced flue gas fires can be installed in apartments and flats as they vent through an external wall rather than a chimney. You will need access to a gas supply and a suitable external wall for the flue terminal. Our Gas Safe engineers will carry out a free survey to confirm whether a gas fire installation is possible in your apartment.

Q. Do I need a carbon monoxide detector with a gas fire?

Yes, building regulations require a carbon monoxide alarm to be fitted in any room where a new gas fire is installed. This is a vital safety measure that protects your household from the risk of carbon monoxide poisoning. We supply and fit audible carbon monoxide detectors as part of every gas fire installation we carry out.
