Window Trickle Vents

Partially defeats the whole object of having sealed double glazing to keep the heat in if people complain that their rooms are cold with the vents open. Might as well keep the unsealed single glaze

I've never complained about cold rooms. It's not keeping the heat in that's the probem, it's getting the moisture out. Even with a cooker hood and the window open in the kitchen, as soon as you start cooking veg the windows throughout the bungalow will steam. I use a dehumidifier too, but all of the ungalows round here seem to have the same problem. As I said, it's caused by modern properties being like a sealed box with double glazing, cavity wall insulation and thick loft insulation. Simply opening a window once a day is pointless.

Single Room MHRV units solve all of these problems completely.

Just curious, how much money per room, including labour, guesstimate is fine. I assume two 5" holes through the wall, with condensation dripping outside. The air inlet and exhaust need to be apart, naturally.

I've been thinking about a heat recovery ventilation retro-fit. I'm too lazy to open the windows every day. :rotfl:

Front Room: Mitsubishi VL-100 for £260
Bathroom & Bedroom: Kair KHRV150 for £260 each
Fitted by local sparkeys for £250

for a look

The only problem I've come across is that the Kair unit is noisy in a severe gale (in the bedroom at night). The Mitsubishi moves more air, and has better external noise rejection than the Kair's.

I've ordered new windows - specifically without trickle vents. That's why I bought the MHRV's.

So why don't you close the door to the kitchen when you cook and open the kitchen window?. When you have finished cooking just close the window and open the door.

Looks like a lot of money for one room.

I was looking at this kind of whole house solution:

For £1,395 it seems to be decent value, it's just that after all the effort of putting in the ducting, surely I might as well go for central air conditioning, with cooling and heating.

Looks great - these things aren't 'moneysaving' but they do improve the quality of life. There's a big initail outlay, but then you get cheaper heating bills. That's the cost of creating a fresh warm dry home - what's the value of that?
Ducting was a no-go in my place, but if I was starting from a blank sheet then I'd love to have Ducted Aircon with HRV combined.
