Totally agree. I got an HRV. It actually is great for ventilation - but only at certain times of the day. Later at night when you're trying to warm the house by some alternate means, the HRV is blowing typically cool air from the ceiling around the house. Completely counter intuitive. What it needs is a heat pump/aircond unit on the HRV intake for winter/summer use. Just using ceiling cavity air (which is sucked in from outside) is a total waste of time, its either too cold in winter or too hot in summer. I'm graphing all this information at present to determine the optimal heating solution for my own home (including searching aliexpress for heat exchange units that may work with the HRV!)
The funny thing about this is HRV stands for "heat recovery ventilation", I think HRV sells them but they cos tmore. Blowing smelly, cold ceiling cavity air into the house is almost never the right option. Pulling in fresh, cooler air, running it through a heat exchanger, you'd be a lot better off. Cleanaire might sell you a heat exchanger.
This is awesome. I might give that a go.
The main reason I was looking at double glazing is our house windows gets fully wet (the whole house). We have only recently bought the house in it about 6 months.
Didn't notice anything till it started to get cold. It does have bats in the roof but I guess we can put another layer it won't cost that much.
But I guess retro fitting the windows might be a cheaper alternative if you didn't notice double glazing did that much difference.
We don't have a heating solution for the house currently which we need to think about as well.
Sounds like you need both ventilation and heating. You'd be better off getting an integrated unit up front than doing what I did, buying the bits separately, then releasing it'd be better if they worked together.
For now, try opening the windows for a half hour a day, ideally earlier in the day, to reduce moisture levels. Make sure you have suitable extraction. If you have windows you can lock open leave them slightly open unless rain will actively come inside.
Proper heat recovery ventilation will reduce wet windows, as will double glazing, but you probably need both for an actual solution.
