New VMC
It can be a good idea to leave the VMC on if you live in an area where radon gas leaches from the rocks.
RA Hammerfest is not that cold as the Gulf Stream keeps it reasonably warmer. In my two years working there it rarely got below -5°C. However, a trip inland such as the road to Alta via Skaidi over the tundra we saw temperatures lower than -25°C.

New VMC
Aaaaarrrrrgh !!!!!
We've just had new super-duper PVC windows fitted to the front of our house. The old PVC ones were badly fitted, the tilt and turn mechanisms didn't work properly, the seals were bad and there was nothing to be done to fix them.
I've already posted about the lack of necessity to have a VMC. We don't suffer from damp, all inside doors are open and we aerate the house regularly. With dogs and our own comings and goings, there is plenty of air flow !
But .....
According to the norms for fitting the new windows, we are obliged to have ventilation grills, even in rooms that have windows with grills on the opposite side of the room. The ventilation grills that have been fitted are supposedly self-adjusting depending on the flow of air from outside. The front of the house faces north east and since last night, there has been a cold north easterly blowing. The incoming air from the grill is as bad as having the windows open on a tilt - it's a horrible cold draught and we haven't got down to winter temperatures yet !
That said, it's only a problem when the wind is from the north-east, but that's fairly frequent here in the winter.
We've got the installer coming round tomorrow but suspect he'll say that everything is as it should be and because we haven't got a VMV ..... There's no point in arguing with him because no-one can win and it's not his fault. We have a draughty granite farmhouse, not a modern, hermetically sealed box. So once he's gone, I shall push pipe insulation into the air slots, problem solved (and of course we won't tell him !). The windows themselves are brilliant but the extra ventilation is totally unnecessary and totally unacceptable to us. The pipe insulation can easily be removed in the spring and doesn't leave sticky marks.

New VMC
When we bought our house the VMC had been turned off because the previous owner said it was expensive to run. The walls were showing signs of rising damp.
There is no DPC to the house.
We turned it back on. The damp finally disappeared.
We have not found it expensive to run.
We have just had it all checked and one of the vent pipes had a lot of muck in it. All gone now and working fine.
Get a couple of quotes and ask about decennial insurance for the work and supplied equipment.
Another post has talked about documentation for works done. There could be something to think about there also for insurance if anything unfortunate should happen (god forbid)
