Do you need an air vent with a log burner: everything you need to know

The purpose of air vents

Air vents are a long-standing vital ventilation technique, providing a building with an air
passage and stopping rot formation in insulated houses.

It usually does this in the form of a brick, but the term ‘air brick’ can refer to other small vents
in a similar vein. This vent is often plastic, but can be clay; alternatively, you could employ a
cast-iron vent that does the same job. Regardless, the air brick blends into the background.
In modern construction there is no direct air bridge at a single level between the external and
internal wall. Modern construction relies on trickle vents in each separate room, integrated
into windows and doors.

The brick’s circulation and ventilation help to prevent a build-up of humidity in a structure;
this can lead to a mildew problem or even affect an occupant’s breathing and general health.
The humidity also leads to water forming from condensation; this can infest wood boards
and joints, weakening the property’s integrity – this can even cause irreversible damage to
the building without intervention.

2. Air bricks and log burners

Wood-burning stoves need ventilation for reasons beyond preventing humidity. Fires require
fuel and oxygen – and circulating the air correctly guarantees a source of air that will
obviously ensure that your appliance receives the required air to operate correctly. On top of
this, correct room ventilation also ensures that any of the appliance’s smoke that may enter
the room during re-fuelling, escapes out of the building and does not stay in the room. This
should not happen often but can happen during certain weather events and if the cowl fitted
is not the correct one for your location.

Homes built after 2008 must have a lower air permeability by law; this is part of what
necessitates an air brick or direct air source connection for a log burner. These particular
properties are more airtight, with the minimum level of ventilation based on the stove’s heat
output. Even for older buildings, the stove’s vent can be helpful, and you will not need a
large amount of space for the brick.
