Millions of UK households can already use gas for central heating. If you live in one of these homes, adding a gas fireplace could be the best way to add extra warmth to the rooms you use most often.
Gas is a cost-effective way of heating your home, as it’s cheaper than electricity, and there are some very efficient gas fires and stoves on the market.
You don’t even necessarily need a chimney or flue in your home, as long as you choose a model that can be used without a conventional flue.
If you don’t have a mains gas connection, you still have the option of buying a fire or stove that uses liquid petroleum gas (LPG), although there are fewer of these available.
Our guide will talk you through the different types and help you decide which one is right for you.
The first thing you need to do is find out which type of chimney or flue you have: a traditional chimney, a pre-fabricated flue or a pre-cast flue. You’ll need to make sure you buy a fire or stove which is compatible.
Don’t worry if you don’t have a chimney or flue, as instead you could opt for a flueless gas stove or fire.
Or you could choose a ‘balanced flue’ appliance, which comes with its own flue that’s vented through an external wall. But this means you have to place your stove or fire against an external-facing wall, and create a hole in it for the flue.
If you’re unsure which type of chimney you have, or whether a flueless model is right for your home, consult an installer or retailer for professional advice.
There are two ways that your appliance can be installed:
Your fire or stove will only be able to heat the room it’s installed in. So to get the best value out of it, make sure you’ve got the right output for your room.
If the output is too low, your fire or stove won’t keep you warm enough. If it’s too powerful, you’ll always have to run it at a low temperature, which will be inefficient and could waste money.
The output will be measured in kilowatts (kW). Approximately speaking, to make your room 21°C when it’s 1°C outside, you’ll need 1kW of heat output for every 14 cubic metres of space.
As a rough guide, multiply the height, width and length of the room in metres, then divide this by 14. You can use our tool below to give you an idea.
However, this is only a rough figure for an average home, and other factors can affect the output you’ll need, such as the level of insulation in your home and the number and size of any windows in the room.
If you’re unsure about the wattage you need, consult an installer or retailer for more tailored advice about what suits your property.
There are two main types of fire: glass fronted or open front. And they pretty much do what it says on the tin.
Glass-fronted models have a fixed glass panel in front of the flames. They’re usually more efficient because they are more enclosed and concentrate the heat through the glass into the room.
But they can be high maintenance as you’ll need to remove and clean the glass every now and again to keep it looking its best. Light reflecting on the glass could also prevent you from clearly seeing the flame effect.
Open-fronted fires can have a more realistic appearance and are generally cheaper to buy up front. But they tend to be less efficient than glass-fronted models, so they can have higher running costs over time.
Your gas fire or stove is likely to be a focal point in your room, as well as a source of heat. So it’s important to choose a model that will suit the style of your home.
A modern ‘hole in the wall’ gas fire probably won’t strike the right note if you live in a period property full of original features and vintage furniture. And a traditional outset fire is likely to stick out like a sore thumb in a contemporary, minimalist home.

In practice, efficiency varies depending on the style of the appliance. Inset, glass-fronted models tend to be the most efficient as they’re more enclosed. This means less of the heat escapes into the chimney or flue, and is concentrated through the glass into the room.
Retailers usually provide an efficiency rating, as a percentage, in the information about the appliances, as well as an energy performance certificate (EPC) rating. So if efficiency is important to you, look for these ratings when shopping online or in store.
There are a number of features to look out for when buying your gas fire or stove. These include:
Prices for gas fires and stoves vary widely, from less than £200 for basic models to several thousand pounds for stylish ‘hole in the wall’ fires and large contemporary stoves.
Factors such as size, efficiency and style all play a part in determining the price. As with so many things in life, you’ll generally have to pay more for the biggest, most efficient and trendier models.
Prices also vary between retailers, so it’s worth shopping around to get good value. If you’re on a budget or love a bargain, try shopping in summer when demand is lower, or in autumn for start-of-season sales.
Gas fires and stoves are generally more expensive than their electric counterparts (when comparing like-for-like models). But gas appliances should have lower running costs in the long term because of the lower cost of using gas to heat your home.
To make sure your gas fire or stove is installed safely, it should be fitted by a qualified installer who is Gas Safe registered. The engineer should also check that the chimney, flue or vent system you’ll be using is suitable.
As with all gas appliances, you should get a qualified Gas Safe engineer to check your fire or stove every year to make sure it’s safe to use.
If you’re using a chimney or flue, get it cleaned regularly to make sure it’s kept clear of blockages. Ideally this should be done once or twice a year, depending on how many months of the year you’re using your gas fire for. You should schedule one of these cleans to take place in late summer or early autumn before you first start using your fire or stove.
