Wall vents

Roberto_gas

Lads have air vents in bedroom which blow cold air through out night...have open fire in living area...its a 1980s built...can I block the air vent with something to preserve heat ?

So i presume your open fire is used downstairs but is it lit all the time needing venting.What other vents are in house.I have an open fire gas not used and blocked floor vent to reduce cold draft.Maybe you could add a shutter vent to reduce the cold air draft.

If the only heating in the house is the open fire then the amount of cold air coming in through vents is the least of your problems. I have vents in all rooms with no heating overnight (it is on for an hour or so morning and evening at the moment) and I have a window open in my bedroom. It really isn't cold at the moment.

If you close off the vents in an unheated house you will get mould forming. You need to be exploring other options of creating a bit of heat in the house, but don't seal the ventilation.

Is there a vent in the living room with the fire? If there is then blocking the vents in the bedrooms won't kill you even though it may lead to damp and mold problems.

There is electric and storage heaters as well..shutter vent sounds a better option rather than full block...I just want to block it a bit as right now it's full flow cold draft at nights !!

Thee is instant electric and storage heating

Do a search there is ample ample threads in wall vents here.


Don't block them up. A whole host of other troubles exist. including health related.

OP. This is likely a complex problem. Its possible the open fire is part of the cause but it sounds like you are living in a property that was made to standards that no longer apply so have to make the best of it you can.

If the open fire place is not in use there is a product for installing into the chimney and inflating.

Yeah I know that ..don't want mould etc building due to block of the vents...will blocking plus windows opening daily help ?

Then it looks like closable vent and i have used a j cloth to restrict air flow even more.

I can't advocate blocking them at all. If anything you can get baffles to slow airflow but not stop it or slidable vents. But no one remembers to open windows regularly and youll just end up with black mould around the window.

Heat Merchants are agents for Aereco ventilation products. I’ve EHT wall vents that replaced regular wall vents. They come in different configurations to reduce draughts and reduce noise. They’re humidity sensitive and open more in response to greater humidity. I’ve them in the bedrooms and find them quite good for passive vents.

We have a stove in the living room so we kept the regular unclosable vent as I wouldn’t run the risk of carbon monoxide poisoning.

At night when you close the windows, your breathing will produce moisture. This warm moisture laden air will condense on the cooler surfaces in the bedroom. Likely to be the window panes and the top and corners of the bedroom walls. If you’ve plasterboard, then in no time you’ll start to see mould growth, especially at this time of the year.

Black hole vents

Thats brilliant but we don't know if the problem is a pressure difference in the house or just wind blowing?

The black hole vent will be fine if its a wind problem but nothing is going to stop cold air being drawn in if the problem is a pressure difference caused by other vents, gaps (under doors) or the chimney where air is being sucked out.

Its a problem you need to fully understand before you can fix it.

beauf

Most of these vents should be cowled to stop wind from going straight through them. They are just a 4" hole in the wall otherwise.


You can generally feel a draft or trace them using a smoke pencil
