Air tightness-good idea?

    I was at a funeral at the weekend of an old couple that died from CO poisoning from a faulty boiler and it got me thinking, is airtightness really a good idea?

    If CO is heavier than air then it will sit in the bottom of the house and build up, like radon and CO2, with a heat recover system all your vents are in the ceiling, even with standard ventilation the room vents are generally at a high level. What is the alternative?

    Yes,

    Air tightness is a good idea... if you can achieve it....

    Even in a "leaky" house which suffers from draughts and the like you still stand a good chance of being wiped out by a faulty appliance pumping out carbon monoxide.

    If you have an appliance in doors that is at risk of going faulty and producing this deadly then you really should have a CO alarm fitted ... its a no brainer really... would you risk the absence of a smoke alarm ? I sure wouldn't !!!

    Hi.
    Just came across this and thought it was an interesting question. I have a carbon monoxide alarm in my kitchen which has a stanley cooker/boiler. Do I also need a CO alarm or are they one and the same thing?

    CO= carbon monoxide
    CO2 = carbon dioxide

    New ventilation regs call for 10 m3/hr/m2@50 pa max airtightness and half an airchange background ventiltion, less than 7 requires that you increase the size of your room vents by 50% (remember that building control requires room vents to be constantly open). The alternative is to use Mechanical systems, preferably with heat recovery. These should be failsafe with smoke and co2 detectors. Every cowboy in Ireland will be out to install these systems, they need to be very tightly regulated, as incorrectly designed and installed they can be inefficient and can lead to legionaires desease if filtration systems not maintained. Systems need to be overdesigned for ireland because of our exceptionally high relative humidity.
