Most fire pits are designed for outdoor use. Using the wrong type indoors creates serious safety risks, mainly from carbon monoxide and lack of ventilation. Only a small number of fire pit types are suitable for indoor use, and even those require the right setup.

This guide explains which fire pits can be used indoors and what conditions need to be met for safe use.

Can You Use a Fire Pit Indoors?

You can use a fire pit indoors only if it produces clean combustion and does not release harmful gases into the room. This rules out most traditional fire pits.

Wood and gas both produce carbon monoxide. Without proper ventilation or a flue system, this gas builds up quickly and becomes dangerous.

Types of Fire Pits Safe for Indoor Use

The only widely accepted indoor-safe fire pits are bioethanol models.

Bioethanol burns cleanly and does not produce smoke, ash, or significant amounts of carbon monoxide when used correctly. This allows it to be used in enclosed spaces without a chimney.

These fire pits are commonly used in living rooms, apartments, and indoor seating areas. They are also used in sheltered outdoor spaces where ventilation is limited.

You can view examples in the bioethanol fire pits collection.

Even with clean-burning fuel, airflow still matters. Windows or ventilation points should not be fully sealed during use.

Fire Pits That Are Not Safe Indoors

Wood burning fire pits are not safe for indoor use. They produce smoke, sparks, and carbon monoxide. Without a chimney system, these gases accumulate quickly.

Gas fire pits are also not safe indoors unless they are specifically designed for indoor installation and connected to a proper ventilation system. Standard outdoor gas fire pits do not meet this requirement.

Charcoal and solid fuel fire pits fall into the same category and should never be used indoors.

Ventilation and Air Quality

Even clean-burning fire pits affect indoor air quality. Oxygen levels decrease slightly during use, and small amounts of by-products are still released.

Rooms should have some level of airflow. This does not require open windows at all times, but completely sealed environments should be avoided.

Carbon monoxide detectors are recommended in any space where combustion occurs, even with bioethanol.

Heat and Room Size

Indoor fire pits produce heat at close range. In smaller rooms, this can become noticeable quickly.

Bioethanol units typically produce less heat than gas or wood, which makes them more suitable for enclosed spaces. However, heat still builds up over time.

Room size should match the output of the fire pit. Larger burners in small rooms can make the space uncomfortable. For more on heat output, see what to expect from fire pit heat.

Placement and Surface Safety

Indoor fire pits should be placed on stable, non-flammable surfaces. Materials like stone, tile, or treated surfaces are more suitable than untreated wood.

Clearance around the unit is important. Walls, furniture, and soft furnishings should not be placed too close to the flame.

Tabletop models are often used indoors because they are compact and easier to position. You can view options in the table top fire pits collection.

UK Safety Considerations

In the UK, indoor heating appliances must meet safety standards relating to emissions and ventilation. While bioethanol fire pits are widely used, they are still considered decorative appliances rather than primary heat sources.

Users are responsible for ensuring safe placement and operation. Manufacturer guidelines should always be followed.

Alternatives to Indoor Fire Pits

If you want a fire feature indoors but with more structure, electric fireplaces and built-in gas fireplaces are designed specifically for indoor use.

Outdoor-style fire pits are not direct replacements for these systems. For outdoor spaces that are partially enclosed, outdoor fireplaces may be more suitable.

Summary

Most fire pits are not safe for indoor use. Wood, gas, and charcoal fire pits produce emissions that require ventilation systems.

Bioethanol fire pits are the only common option suitable for indoor environments. They burn cleanly and do not require a chimney, but they still need careful placement and basic ventilation.

Indoor use depends on choosing the correct type and using it in a controlled environment. You can explore the full range in the main fire pits collection.
