I hope someone can advise me, i have gas central heating and the boilers are NOT in the house, i also have a gas hob which of course is in the kitchen.
I have two air vents in the kitchen, one near the floor and one at window height, they let a lot of cold air into the kitchen. Do i need them? The actual holes measure 4 inches x 3 inches and the kitchen is very large.
Any advice would be appreciated.
