Yes please chuck...it'd be good if you know someone. As long as he doesn't shove my arm up my back to have one
Without seeing your property I can't really advise, but the heat recovery ones are a sensible option in some ways.
Sorry if that's a bit vague..
It's that Duke, Tpin. Me thinks he got you a bit over-excited.

Re: Positive Input Ventilation
The fan unit doesn't need to be in a loft - it can be fitted inside a cupboard or on a spare outside wall and boxed in but with access for filter changes etc.A cheaper option would be a constant flow ventilator like those fitted in the newer larger dwellings as standard. These fans run 24/7 at a slow speed and are low-wattage so don't use much electricity. A `booster` switch can be installed at a suitable location which, when used, will increase the speed of the fan (when using a shower for example). Insulated ducts are run from rooms with the most ventilation problems like bathrooms and kitchens and to the unit and a vent run to outside. A series of baffles within the unit prevents air from outside from getting in.

It's called a constant flow vent then? Will have to read up on that Judd, thanks.
Just thought though...does it let in fresh air?
And, you say it's usually for new properties - I've read about those and I'm sure opening windows makes it useless or less efficient?
I've a 60s bungalow T pin not a 70s
Edited to add:
I read up on the NuAire Flatmaster, the one to put on an outside wall for apartments etc....is that the one you meant in your 1st paragraph Judd?
