Sufficient room ventilation is a must when installing or considering reopening a fireplace. This is because in order for a fire to properly burn it requires a considerable amount of air. Without this the fire will produce large amounts of Carbon Monoxide which is extremely dangerous. Whilst vents may not be needed in older homes, due to already having sufficient ventilation, modern homes will require this.
Regardless of what fuel your fireplace burns, a vent is required. Fitters will have a range of vents available from simple grills, to more complex ducts. However, it may be a cheaper option to check out your DIY stores first. These vents must not be closable, and the amount of ventilation required must be equal to, or at least 50% of the throat opening to the chimney or flue.
This need not apply if you’re reopening a fireplace, unless extensive building work has been done or the fireplace has been redesigned. All vents new or old must comply with building regulations, proving the vents cannot be blocked, removed or altered. Installers will fit the vents to minimise this and to help prevent noise coming through and drafts.
Quite often, home owners have found their rooms to be colder since having the vents installed. Where you have your vent installed is an important factor to consider when deciding to have a fireplace installed or reopened. If the vent has been installed at ground level away from the fireplace the cold air will not mix with the warmer air already in the room creating the draft.
The ideal place to have your vent fitted would be on the wall next to the fireplace, this is because the cold air coming in from the vent can go straight up the chimney without cooling the room.
