how long until you get hydro / gas bills to see what kind of savings are being made?

also...being LG, it will die the day after the warranty expires and it'll be a discontinued model so no replacement parts available. :p

We'll get a bill with usage at the end of the month, but it's almost impossible to compare one year to the next based on just a single month. The usage graph compares the last 3 years, but only has this year's monthly average temp.

As far as the warranty goes.... we're planning on selling/moving in one or two years so it'll be somebody else's problem. :)

Also got confirmation on installation for extra insulation in the attic, and spray foam insulation for the one room cement wall, and rafters in a couple of basement rooms (that don't have a false ceiling).

It used to be you wanted to be out of the house for about 24 hours for extensive spray foam installations for the off gassing if you can. Is that still something they are recomending?
 
I have considered spray-foaming my attic and basement (the attic has pink blow-in), but after reading horror stories about people tearing down their houses because the foam wouldn't stop off-gassing, making everyone sick, I didn't want to risk it.

I can't speak to Ontario, but for Alberta the general consensus seems to be 'don't spray foam your attic' due to issues of moisture entrapment causing rot to roof sheets and trusses. The small potential gain in energy saving over traditional cellulose insulation, couple with higher install cost and moisture issues means it's generally not recommended.

I'm sure there's spray foam companies that would argue otherwise, but it's really only done in commercial/industrial steel and aluminum structures here.
 
In our case, the spray foam is only going on an exposed cement exterior wall in our basement, as well as the rafters in a couple of basement rooms where they're exposed. Attic is getting better/more traditional insulation over and above the old stuff that's up there.

That makes sense. It's becoming the norm for basement walls and around rim joists (though that's a bit of a mix depending on builder, etc). I considered redoing my rim joists with foam, but access for some of them is tough and I'll likely just stuff more insulation in them.
 
Spraying basement walls makes sense to me, you get an airtight seal so no worries about condensation being below grade like you have with traditional insulation/vapour barrier.

Spraying an attic though, I've never quite understood as it's meant to "breathe". For example, radon gas naturally rises and should vent out your attic/roof. Having the attic entirely airtight seems counter-productive to those sort of concepts.
 
Ya after hearing what I heard I wasn't going to hence why i blew in some pink, but just another reason not to do it, I got a minium of R40 most of my attic is around R90, my basement I will be going with a ridged foam board on my outside walls and the rest has roll out and the inner wall I don't have to worry about.

I did think about going with cellulose but after talking to a family member who works at Home Depot I was advised by him and a friend who builds homes to use pink since it doesn't settle. it has made a huge difference since I did it, my neighbours ( house is a semi ) have the same setup to a T as me besides attic insulation and their gas bills are double sometimes triple mine.

I don't dislike foam in fact I prefer it but the horror stories scared me away from it, since I don't have much to do I will stick with something I don't have to worry about.

If my rough calculations are correct, based on about 31 hrs of operation (45.84 kWh) I'm seeing a little under 1.5 kW / hour over all three units. Using the listed rate (13.84 cents / kWh) that comes out to under $150 for a 30 day month which sounds pretty damn good compared to the $225 - $300 extra we pay on our hydro bill during the heating season.

My better half is still not completely sold on the idea that not all rooms are getting direct heat so the ones off of the hall seem to be a couple of degrees cooler than the directly heated rooms.

We got two of these units, and one slightly smaller one from the same line......
