    Hearing so many mixed messages I'm am going to see if Boards can help me solve the problem.

    New build - 3,000sq. ft. Storey and a half
    UFH and Air to Water.
    More than likely going for triple glazed Aluclad windows. U value .95
    We don't want a passive house - just a healthy, economical house?

    As much information in the ladybird version much appreciated ! Thank you.
    If you can recommend specific brands in Cork or Munster please pm me.


    Thank you

    Hi, my tuppence worth is if I was building a new house mvhr is a no-brainer. In the overall scheme the cost is reasonable, the benefits considerable. You don't need to go the full passive route but you should be specifying the airtightness level you require.

    Forget the ladybird approach, there is no substitute for lots of research on this and every other aspect of house building. Don't make the mistake of leaving it all to the professionals (unless you are very rich and employing a project managerðŸ˜).

    tend to agree with this - it's easy to build in MHRV in a new house, and it has some benefits over DCV in that there isn't a perception of draughts on colder days, and you can sound proof rooms more easily.

    A good thread to follow is this one: https://www.boards.ie/b/thread/2057496673 where the poster DIY'd MHRV in their bungalow - lots of pics and temperatures experienced. As ladybird as it gets!

    The one advice I have is: consider the location of the unit itself and accessibility for frequently changing filters. make that bit easy for yourself
