    Given the following parameters, a small bedroom, single occupant, cold nights so window (Velux)shut, bedroom door shut for privacy, how does one manage two air changes an hour ? Vents top and bottom of the door or though the wall next the corridor? Draught under the door? Ideas welcome.

    Ideal! A small self-contained through-the-wall (or roof or window pane) heat-recovery ventilation unit. Anyone know of any good quality ones?

    Probably air leakage ( unwanted ventilation ) will be giving you more than you want any way if the room is is oldish and in the UK and for sure if it is newish.

    I have been looking to install a Heat Recovery Unit in the 2nd bed room which got more condesation problem. Just found Vent-Axia's HR30W. Looks good and price is reasonable compared to other. Now looking to find someone who can fit it. Anyone recommendations or anyone who already installed the same near Croydon area.

    Do these units make any noise when they are running? Personally, I would find any mechanical noise rather annoying if I was trying to get to sleep and presumably it is during the time the room is occupied over night that the condensation problems occur?

    Try the Kair KHRV150 from Kiltox - http://www.kiltox.co.uk/ventilation.htm - claims to be "whisper quiet for bedrooms".

    I've bought 'whisper quiet' heaters before. The sales people lie.

    In a bedroom at night when everything is still, you can hear the mains hum from our radio. The idea of bolting some contraption on the side of your room to clank and whir all night, clogging itself up with dust and debris and requiring regular maintenance fills me with horror.

    In our build we have a very shallow roof pitch and no real loft space (if the current designs are passed), so my hopes of using passive ventilation are looking optimisitic at best. We'll probably be pushed into using some infernal machine to achieve good quality air, which is deeply disappointing.

    Our new build is also a "room on the roof" design. We were able to accomadate a powered whole house vent system. If you were sleeping near the fan unit it would too noisy so good placement is essential. Ours is housed in the eaves above the back door porch quite some distance from the bedrooms and is totaly inaudable in the bedrooms. The air vents themselves make a little noise but it's not much and it doesn't bother us at all (we live in the quiet country side) Interestingly the vents get a lot quieter when the decorative vent cover (not exactly a grill) is removed for cleaning the filter - this sugests some improvement in the design is possible. I suspect a simple screen made from a porous cloth (loud speaker cloth?) would be quieter than the plastic things provided with ours.

    The following also do through the wall heat recovery units http://www.stadium-ventilation.co.uk/vents/Vent_Heat_rec_.htm. Have specified them before for dampness in flats etc.. Core drill use ; fairly easy to fit IMHO.
    Alternatively http://www.condensationshop.com/passyfier_tch.shtml have beenn used to control the humidity in unmanned light houses.
    No commercial connections with either company :)
