Hi,

I'm curious as to what boiler you had fitted.
Are you on oil?

GSR.

Sorry for late reply, I've been away for a few days.
I have gas fired warm air central heating.:)

No Carbon MONOXIDE kills so get a CO alarm if you are even thinking about blocking it up.

Sorry head full of energy efficiency and renewables Meant to say carbon monoxide of course. Any fire over 7kw needs adequate ventilation you can have floor vents of you have floorboards etc but you will need to make sure they have sufficient airflow...

Could it also be because you have a boiler in the living room as well by the sounds of it that the vent is required?

Could be, but if you have a combi with fanned/balanced flue it wouldn't

I had cavity wall insulation fitted and the company insisted on putting a bl**dy great air vent in the living room wall as we have an open fire at times. When I decorated I replaced their one with a sliding one, so I can shut it in cold weather and stop the horrendous drafts coming through.

My Hsng Assn house had double glazing installed a few months ago. Looks great and the windows are not a problem but the vents are. Twice the length of the others and twice as many in some rooms. A very thin plastic cover internally and the external part sticks out from the frame at least an inch. Only the kitchen one is open and the cold air is very noticeable as well as external noise. I complained and 2 inspectors have visited and both said there is nothing they can do.
We have a gas boiler in the kitchen. I have all internal doors open at all times and bedroom windows are not closed from early mornin till late night. Can anyone recommend something to block the vents please?

Well technicaly your right A build of Co2 will kill also. As its heavier than oxygen it will displace oxygen and suffocation will occur.

The difference with carbon monoxide is that it form a bond with haemoglobin that's stronger than that of oxygen or carbon dioxide and isn't breathed out as easily massively reducing the ability of the blood itself to take in oxygen. Hence why people with monoxide poisoning have to put in oxygen chambers to force as much oxygen into the red blood cells as possible.

I'm a bit confused. Why do they test the airtightness of a house when assessing it's energy efficiency... and then stipulate that all the rooms need to have ventilation to the outside?

Surely the heat conservation benefits of an airtight house are nullified by the health benefits of good ventilation. :huh:

There you are you see..as per post #27, the alarm is triggered by spicy cooking,air freshner or a squirt of perfume.

How much use is that?

If it alarms, how can anyone be sure what its alarming for?

If it does alarm,what will you do? Ring the fire brigade or ring the gas company who will duly cut you off thus causing major inconvenience and expense?

so you're in the middle of cooking and the air is heavy with spice and the alarm goes beep beep..very slowly. Before it starts screaming you open a window or put on an extractor fan. Pretty obvious what is causing it. Much the same thing as burnt toast sets off a smoke alarm - you wouldn't call the fire brigade then would you?
If someone isn't capable of following the instructions for a CO alarm then they might be better off with the strip blob detector, they are also useful for taking to hotels etc. A schoolfriend of mine died in a hotel from CO poisoning so it does happen.

I guess it's because you can get the house warm then when the heating goes off it will stay warm all night assuming you can close off the ventilation. I only need ventilation in my kitchen - where my gas fired appliances are so if I shut the kitchen doors the heat in the other rooms stays there longer.
Sometimes I put an oil radiator in the bedroom and for that sort of thing I don't need air vents open and it doesn't take so much energy to keep the room warm.
