    Not sure what you mean by the "best"!

    Imo, there is no "best" system for the Irish climate.
    What's important is that the system is optimised for the specific project in question. So, it should be sized correctly, the duct layout & lenght should be designed so that the ducts are as short as possible, run within the thermal envelope and should not allow sound transmission from room to room. The power to the unit should be integrated with the smoke alarm system and the ducts should have automatic closers in case of fire.

    As Mick said not sure what you mean by best, possibly trying to decide whether to go with a centralised mechanical heat recovery ventilation system or an alternative such as a demand controlled ventilation type system?

    The demand controlled products don't always offer heat recovery but they are being seen as an alternative to traditional HRV systems, if that is the question then i think the system mick has outlined is best as questions have been raised over demand controlled units ability to get fresh air into a house with Irish wind speeds and pressures. They do not give same control over air changes as centralised HRV. That said I am not very familar with the demand type system Maybe someone could clear up these possible issues?

    I agree with previous comments. Make sure that the supplier/installer knows what (s)he is about and will be around to service the unit(s). Some guys have come into this business recently and disappeared quickly. It is not rocket science but it must be done right.

    Just to add that the filters should be readily accessible for inspection/renewing
