Added insulation, now furnace runs MORE often???
|

| mkirsch1@rochester.rr.com 2006-02-22, 1:21 pm |
| Hi, I purchased my first home about two months ago, and after I got the
first gas bill... Well, I can't repeat what I said...
The attic had old R13 fiberglass batts between the joists and a couple
of inches of blown-in cellulose on top of that. Definitely not enough
for Western NY winters. So, the tax refund went toward 20 rolls of R30
attic blanket (on sale at Home Depot, cheaper than R25), which I just
finished installing yesterday evening. Now the main area of the house
has R50, just over what the Owens-Corning and EnergyStar websites
recommend for my area.
When I moved in, the furnace ran all the time, and there were wide
variations in temperature throughout the house. I re-balanced the
system by playing with registers and dampers and got it to where the
furnace would run once an hour for 20-25 minutes, and the temperatures
in the rooms were much more even.
Now that I have the insulation, the furnace runs 10-12 minutes, then is
off for 15-20 minutes, and then runs again for 10-12 minutes. I'm
wondering if the insulation was a good thing or a bad thing now...
Shouldn't the furnace run LESS often?

Now you have an oversized furnace, thats gonna short cycle you to death....
Gee..its not rocket science...but you sure didnt do your homework....
That $40 a month in savings went out the window, and in order for it to make
any savings at all, its gonna cost ya.

Man-O-Man. I wish you would check with the experts first. Now you've
wasted a lot of money.
First off, whatever the websites said about insulation, you should
only use 1/2 that amount. YOu should know that. They are selling
insulation. They want you to buy a lot so they can make a lot of
money. Now, your home will have "temperature-layers". This happens
when you use too much insulation. The warm air rises and cant make its
way all the way through the insulation and out the attic. It builds up
a layer of heat and stops. Then more heat is added to the home and it
to heads upwards and "layers" itself in the insulation too. Soon, you
have warm insulation that now trys to draw heat towards it just like a
sponge. Now your furnace runs more and longer as its heated is being
drawn toward the warm attic and insulation layers. This stratification
of warm air "locks-in" the heat and causes your furnace to run too
much. Now, you need to either
1) Install a larger furnace
or
2) Remove half the insulation (in depth) you just added to the attic
You might also purchase some @attic-boosters to help ventilate a
"break-up" the stratified layers of heat in your insulation.

You need to replace the thermostat with a digital thermostat. The old ones
are not able to account for the added insulation.

Bullshit. R-60 or better is recommended in some colder climates.

That's what ceiling fans are for.
Furthermore, decent registers project the air downward toward the
floor, minimizing the problem of stratification in the first place.
Floor registers are bad, because convection losses tend to make the
warmer stratify before it can complete the loop.
Again, that's what ceiling fans are for.

What a crock of horserace.

God Damn. Took you long enough, Johnny.
I thought you'd been here a while? Can you say, "hook, line & sinker?"
I did like your rebuttal though. :-)

ROFLMAO.... Bubba, I drank a lot last night, but had to read that twice this
morning. Good humor.
Heat travels toward cold, light travels toward dark, wet travels toward
dry... Basic physics there.
Warm air rises, thus causing stratification. Need ceiling fan or constant
blower mode to reduce stratification.
There are 3 kinds of heat (4 if you include the blond down the street)....
Radiant, Conductive and Convective (and friction). Radiant and Conductive
heat travels in all directions, Convective heat rises unless forced
otherwise by moving the air, (the blond travels down the street causing
excess friction on the brakes).

Friction is simply a conversion of kinetic energy to heat (braking).

As for the blond down ths street, I never use any lube, because I
prefer friction, and that ain't fiction. Pardon my diction.
Always remember:
The angle of the dangle is inversely proportional to the heat of the
meat.

Been away from the NG for a few days,
and my ISP has incompletes, so I have to grab headers from Giganews
every once in a while. ;`(

How did you calculate the $40/month savings?
