Regulations: Stove Ventilation in England & Wales
A good air supply is essential to the safe working of a heat producing appliance. The amount of air required will depend on the type of appliance, the input/output and the type of fuel it burns. For your convenience, we have created a stove ventilation calculator (see below) and outlined extracts from the following regulations:
- For detailed guidance, refer to the full versions of the regulations linked above.
Approved Document J: Combustion appliances and fuel storage systems
Requirement: Air supply
J1: Combustion appliances shall be so installed that there is an adequate supply of air to them for combustion, to prevent overheating and for the efficient working of any flue.
Section 1: Provisions which apply generally to combustion installations
1.10: Permanently open air vents should be non-adjustable, sized to admit sufficient air for the purpose intended and positioned where they are unlikely to become blocked. Ventilators should be installed so that building occupants are not provoked into sealing them against draughts or noise. Air vents should not be located within a fireplace recess except on the basis of specialist advice.
1.16: In noisy areas it may be necessary to install noise-attenuated ventilators to limit the entry of noise into the building.
Section 2: Additional provisions for appliances burning solid fuel (including solid biofuel) with a rated output up to 50kW
2.2: Any room or space containing an appliance should have a permanent air vent opening of at least the size shown in Table 1. For appliances designed to burn a range of different solid fuels the air supply should be designed to accommodate burning the fuel that produces the highest heating output.

General notes:
- This calculation assumes the air vent will be in the same room as the stove and positioned to access directly to the outside.
- Rytons AirCore and AirLiner ventilation sets feature anti-draught systems to promote a comfortable environment in the room. Achieve further draught protection by placing the air vent close to the appliance or at a high level close to the ceiling.
- Noise attenuating Acoustic AirCore and AirLiner Ventilation Sets are available for areas close to continuous noise (e.g. a main road).
- Rytons through-wall stove ventilators have equivalent area calculations as required by Approved Document J and HETAS Guidelines.
- Rytons through-wall stove ventilators are HETAS Approved for use with solid fuel, wood and bio-mass appliances.
