Ventless gas fireplace cost guide

Ventless gas fires are becoming increasingly popular, particularly in modern homes that don’t have a chimney. As the name says, they don’t require a vent, so they can be installed pretty much anywhere in a house. But what’s the cost?

Ventless gas fires are becoming increasingly popular, particularly in modern homes that don’t have a chimney. As the name says, they don’t require a vent, so they can be installed pretty much anywhere in a house. There’s also a range of designs to suit you – you may opt for a slick modern design or a more traditional one; the initial cost will depend on this choice.

Because there is gas involved, you will need to have your fireplace installed by a professional gas fitter who is Gas Safe registered. Read on to find out how much a ventless gas fireplace costs.

The cost of a ventless gas fireplace initially will depend on the design you choose. This can be £1,200 upwards. It’s worth remembering that although there’s an upfront expense at the beginning, the running costs of a ventless gas fire tend to be lower as they are more energy-efficient. A ceramic plaque burner is used to transfer a controllable level of heat, making the room cosy and warm.

Depending on where your ventless gas fire is to be positioned, it might require decoration of the area – for example, you may need a change of paint.

Cost to install ventless gas fireplace

The cost to install a ventless gas fireplace will depend on a number of factors such as the chosen location of installation, the style of the fire and where you are based geographically. Typically, installation costs will be more expensive in London. On average, you’re looking to pay between £100 – £200 to install your gas fire.

Other costs to consider are annual servicing of the fire which costs on average between £60 – £100. As there is gas involved, it’s also worth ensuring you have a carbon monoxide sensor installed in the room. These can cost between £10 – £20, but your Gas Safe installer will be able to advise you on this.

How does a ventless fireplace work?

The ventless fire burns gas through a type of catalytic convertor to release heat. To burn effectively, it takes oxygen from the room.

Are ventless gas fireplaces safe?

Yes, ventless gas fireplaces have a feature called an oxygen detection system. This means that it’ll automatically turn off if oxygen levels in the room fall below a certain level. As with any gas appliance, it is important to have it installed correctly and it’s also important to use effective carbon monoxide alarms.

Are ventless gas fireplaces more energy efficient?

The system uses less energy so it’s generally cheaper to run than a vented fire. Installation is often cheaper, but the initial cost of the fireplace can be more expensive. Unlike wood-burning fireplaces, ventless models produce no ash and no airborne debris, making them an eco-friendly option.
