Vents letting in cold air...

20
Found 12th Nov 2013
Bit of a builders/diy one this.
We have a vent in our living room bay window. It goes directly outside and cold air pours through it!

I was checking everywhere for draughts and thought ok well let's just check the vent to see how much is coming through.... Lots. It makes the lower part of the room very cold negating some of the effect of the open fire... Should this be and what could be done? It just isn't efficient for heating! Pic bellow.

LOL. X)
We have one in our front room also, I blocked it off with a bit of cardboard. When the guy came round to service the boiler (back)/gas fire he said I shouldn't have as it could be dangerous.

I guess if it was a sealed room the oxygen would burn and there would be no 'flow' coming in.

Might be a consideration?
Suspended timber floor at a guess ?
Suspended
as its there to stop you dying just turn the heating up a bit
could stick something infront to deflect air streams though so draft isn't direct onto yourself
We have the same issue, draft is so bad you can see the curtains moving and doors rattling
It's there for a reason, a legal one. If you want to lose the air vent to outside, lose the fire. Some people don't want to stay alive.

That sounds like you have a smashed window, pull back the winter curtains and have a look.
from what I've been told is if you have a gas fire or real fire you HAVE to have a vent for circulation because if not poisonous fumes could gather.
you can buy different vents though that you control the amount of flow
I used to live in a house with a stupid vents on the wall by the floor, I blocked them up with insulation, thing is the next and subsequent houses Ive lived in have had no vents yet they all had boilers/central heating. So why did the first one have so many vents?
Ive been told if you have a flueless gas fire then you need a air vent.
You can fit a device inside the pipe that runs through the wall, it's basically a series of baffles that allow air through but slows it down so that you don't feel the draught, you simply remove the vent cover and slide it in then replace the cover. You should be able to pick one up in most plumb centre type stores
Just checked and they're called "baffled air vents". Apparently the best on is called a black hole vent

We have an open fireplace in the living room and i had assumed it was a requirement. however it was a more "what can i do to stop it being so bloody cold :P

after googling it that seems to be exactly what we have!

It just feels like (if you could see it) it would be cold air waterfall.
We had one of these fitted when the cavity wall insulation was done,compulsory H & Safety.

Just block mine with cardboard when its cold,mind you the oxygen in the room can get low so cracking open the lounge door is a good idea if blocking vents.
We had a draught from an air brick in the living room and knew we couldn't block it off but spent ages in Wickes, B&Q and Homebase looking for something that would help. We didn't find anything suitable until my wife happened to speak to an old friend who's husband is an eminent architect.

His advice has really helped.

put a kazoo in the vent and use it as an alarm to put a jumper on

loads of vents look like that from the outside, its what's inside the pipe that makes the difference. you should never feel a draft from a baffled vent. mine looked exactly like the one in your link but was just a plain pipe. the easiest way to check is to go outside the house in the dark and look at the vent, if you can see light from inside the house through the vent then its not a baffled vent
