cold

They even had their outhouses snowed shut:

So they built two-story outhouses :-)

Rockwool has an insulation value of about the same as fiberglass batt. It w ithstands much higher temperatures and that's why it's under the roof. The convective air stream is starting out very cold and you probably don't have enough leakage to warm it much so it still stays cold at the vent.

Maybe you're over-ventilating. Do you have any numbers on your actual excha nge rate?

"hyperventilating"?

I used to have one of those. The problem was the darned upstairs neighbours. ;)

Well, yeah, but if we had heat loss through the cathedral roof there would have to be snow melt somewhere. And there isn't anywhere, niether at the ridge not the gutter area (large 4ft overhangs) nor anywhere else.

I don't, but I am not at all concerned about that. The air stays fresh, in part because the wood stove and pellet stove want they share. When we bought the house I reduced it a tad because at some point we no longer used the open fireplaces. Those were converted with inserts (wood and pellet). In summer the air in the house changes more than once per our, in the office and living area pretty much completely.

If the roof is ventilated properly the roof will be the same temperature as the air around it. Heat from the house won't melt the snow but heat will (obviously) be lost to the outside.

No such thing.

No one's talking about the roof ventilation, dumbass; we were talking about his interior fresh air ventilation to eliminate stale air and mildew.

I'm guessing the ceiling is about R20 during heating season with an even higher equivalent during cooling season because of the rockwool and air ducting.

The only other explanation is you're being short changed on those cords- have you taken a measurement of the delivery ever?

He certainly was.

Possible. The largest heat loss we have is through the single-pane windows but it would be prohibitively expensive to switch those. And it isn't as bad as usual because the glass is very thick.

Yep, they are honest guys. Also, with the way we stack it up after delivery it is easy to see how much is there:

Again, it can't be much. If you have snow on the roof and it is just slightly under freezing during the day this snow will partially melt on not so well insulated houses. On ours it doesn't. If does not matter how the heat gets out, heat is heat and it will melt stuff.

Yikes! One skinny yellow plastic gas pipe replaces all that wood!

Yeah, but has to run for 20 miles!

GREAT PHOTO!

Your neatness is irritating beyond belief! The view to the left in the photo looks out over a panorama?

Nice property.

Yeah, show us more.

Joerg: Your observed that you've been using

Yes. And every conceiveble consequence is predicted to be terrible. Floods. Droughts. Storms. Crop failures. Species eradication. Pests. Weeds. Starvation. Wars. Disease. Political instability. Many other Bad Things.

That would require several months of blasting to lay pipes from El Dorado Hills to our town, on account of the ground being mostly bedrock.

Yes, we can see two miles to the south but I like the east view out of my office better:

Those woods is where I busted two rear axles on my mountain bike within the last few weeks. On several of the trails you think you are way out in the wilderness. This is why I always tell my wife where I am heading. Else, if I crash in there they may not find me in time. There's even some cell phone white spaces in there, "cannot find network".

Thanks. But it's a ton of work. When we bought the house we had no idea how much work a fully landscaped 1/2 acre really is.
