That's not the question -- the question is how two units of the _SAME_
efficiency have any significant savings based solely on sizing.
As the conclusion of the above report states, they couldn't show a
It was near zero out, taking 2.5 hrs to raise temp 6 f is probably
normal, Ive set back to 58 for a week and it might take 6-10 hrs to
get warm. What type of furnace do you have, single stage 82% is
cheapest, 92%+ dual stage VSDC is the most expensive. Dual stage has a
low btu output for normal use and comfort and goes on high fire or
full output when needed, my second stage goes on if I put the
thermostat up 2 or 3 f. I dought you have a heating issue, most houses
are wrongly oversized out of laziness by the installer to do a load
calculation and make a bit more money selling a more expensive unit. I
read another post you did at alt building, you should get the rated-
guarnteed specs on your windows for Air Infiltration of your new
windows. There I bet its installer error or defective windows, you
should not feel air comming in new windows, and more insulation will
help save you money.
Thanks for you thoughts Mark (and everyone else). I know my furnace
is 80% effeciency, but I'm not sure if I have a dual stage (I doubt
it). I'm going to snag a few pics of the area of my window where I
believe air is entering and post them tonight. I'm almost positive
its the poor seal on the sides of the lower sash.
The make of the furnace is York and the windows are by SilverLine.
I'm not sure of the models. I'm not sure where I can find any other
information on the model. I'm still waiting for the builder to get
back to me on what series of windows are installed. I have the
builder coming out tomorrow. Any specific questions I should ask?
What model of windows and furnace I have? Would he know the
infiltration data or is that something I can find out with the model/
series # of the windows?
The SilverLine windows are double hung windows. I pulled open the
lower sash last night and noticed that there is only a small piece of
"fuzzy" felt like material that seals the lower sash on the sides
closed. I believe, on windy days, the wind makes it way through this
"fuzzy" felt and into the weight chambers and up and into the room.
wonder if I should install better weather stripping on the windows
