Slowly getting there on the insulation/draught exclusion so on the way to a well insulated house with low(er) infiltration.

Actuallly I'm fairly sure that by the time I've finshed the hidden stuff incoming air will be confined to a dodgy back door (which will be replaced with a nice home made oak job and fitted to a new frame rather than thrown at an old one), a monstrous UPVC creation where a front door with sidelights should be (again to be replaced ASAP), the three air bricks in our nominal bedrooms (2 upstairs & one downstairs used as an office) and a new airway I put in behind our woodburner as once I have done the front room floor there will be no other free air flow into the room.

Our horrible UPVC double glazing has no trickle vents but the new velux type windows I am fitting (in each each bedroom) have. I will be changing the existing windows but not until I have saved up some money - probably at least a couple of years if not longer and will either make my own/buy oak ones (We like Mr Vernons Yorshire Sashes) or get super duper scandinavians - haven't decided.

The 'bedroom' airbricks are are 9"X9" and I'm inclined to keep them but put manually closeable vents on the inside. With single unit heat recovery ventilation units in the kitchen and bathroom to mitigate for smells/moisture. The house is a small dormer bungalow with a floor area just over 80m2 and a volume of around 260m3.

Does this make sense or should I go for whole house (or in our case all but one room due to ducting issues) MVHR or stick with passive/manual ventilation.

Thanks in advance .

Will post back when I get nearer to the MVHR stage then.
