It is not something many people would initially consider when planning to install a stove, yet it is a very important factor. Many kitchens have extractor fans as a means to removing unpleasant cooking smells from the room, which causes negative pressure. This isn’t very good if you have a wood, multifuel or gas burning stove in the room, as it needs positive chimney pressure to successfully remove combusted gases from the home.
Locating your stove too close to an extractor fan can lead to the smoke being pulled back into the room or lethargically lingering in the flue or chimney. Both are bad news and need to be stopped. Luckily, there are ways around this.
First suggestion is to install an air vent in the room, between the two appliances. This would hopefully provide enough air to supply both appliances without causing one to draw air from the other. Alternatively, a room sealed stove receives air externally, meaning it is not trying to pull from the room, and pressure is maintained in the chimney.
Technological advances are also on hand to help. Sensors can be put in the chimney and extractor fan. When the sensors detect that there is negative pressure in the chimney and then regulates the extractor fan to help combat this.
With a gas fire, a balanced flue is a great means of getting around the issue. Balanced flue brings fresh air in whilst venting the burnt gases to the outside.
In conclusion, installing a stove in a kitchen is possible, you just need to make sure you plan appropriately. We recommend consulting a qualified HETAS qualified engineer who can survey the room and perform an air check in the room with the extractor fan running.
