i figure heating oil in New England will pass $5/gallon this
winter. assuming we have similar weather to last winter, that
would put my winter heating bill at $10,000.
i have quotes for insulating my house, which currently only
has a 6" cap of that stuff that looks like vermiculite (post &
beam, no wall insulation at all), of $10,067.
it seems to me that the payback on the insulation will be
pretty short, but what's the formula for figuring it?

You'd need to know how much less oil you would use as a result of the
insulation being installed and I'd doubt whether you could know that unitl
it's installed and you've been through a whole season.  I'm sure you'll be
told by the people wanting to sell it to you that you'll achieve 'x'
improvement, but I'd not believe it.  Once you have the comparitive figures
of usage of oil against cost of insulation installation, you could work out
the time to amortise it, till then.....

actually, no. one of the reasons i'm inclined to accept this
bid is because he makes no claims of dramatic savings through
his product, *and*, more importantly to me at least, he has a
working knowledge of the period construction of my house; he
*knows* where there are likely to be diagonal crossbracings of
the post & beam frame.
every other contractor was telling me how they apply
insulation assuming balloon framing (post 1890s)... which
would leave huge uninsulated gaps in a post & beam (ca.1815).
it gives me conniptions when realtors don't know architectural
styles/periods, but if a contractor in New England can't
differentiate between post & beam buildings & balloon
construction, they really have no business contracting. they
need entirely different approaches for almost everything.

I hate to say this but it might be cheaper to do a "hillbilly remodel".  That
is, have a fire and use the insurance to build new.  Yaaaa, I know, you like
the place...

The problem I see is that even after the insulation installation, you're still
going to have a drafty old house that is almost impossible to seal up.

I've been working with a friend on a similar situation.  His house is turn of
the century.  He had the foamed-in-place wall insulation installed by a guy
who knew what he was doing.  I borrowed a thermal imaging camera to make sure.
This foam was supposed to seal the gaps between the walls and floors and it
probably did, judging by how much foam is visible in the basement.  Still the
house has cold drafty floors.  A look with a thermal imaging camera shows cold
air coming in everywhere - around the windows despite caulking.  through the
tiny cracks in the hardwood flooring, despite floor insulation.  Around pipe
and wire wall penetrations.  Finding and sealing all of these would be a
career.

The solution we settled on was to quit chasing every leak and instead
overwhelm them with heat.  We installed a free-standing wood boiler and
under-the-floor hydronic radiant heat.  Now the system simply overwhelms the
inleakage.

His is a very small house so it doesn't take that much wood to accomplish the
deed.  Firewood is free for the hauling from construction sites so he has a
huge surplus of that.

The main point of this post (other than to commiserate with you about the
amount of work and cost involved) is to suggest that you rent/borrow/hire a
thermal imaging camera, perhaps before but certainly after the insulation is
installed.  Connect the output of the camera to a video recorder so that you
can review it later.  This video will be invaluable in tracking down the air
leaks that will remain.

There are consultants that do these surveys and they usually have a "fan wall"
that is installed over a door with enough air handling capacity to reduce the
pressure in the house substantially.  That really makes infiltration routes
stand out in the imager.

You can do the same thing with a variety of improvised fans.  Or even a big
fire in the fireplace in the winter.

heh. you're right, he didn't specify *which* century...
the thing is, in my old house, i don't particularly want to
make it completely tight. i want less heat loss, but i don't
want the issues of a too-tight house either. currently, the
only noticably drafty area is the to-be-rebuilt front entry &
one particular outlet in the dining room.
the previous owner did a very good job caulking the sills &
around windows. i do annual caulking checks in the fall to
make sure everything is still intact. (BTW, never use that
canned expanding foam, Great Stuff, around chickens. they
think it's some kind of treat)

Well at least that is positive but it still doesn't help you to figure out
the amortisation of the costs though.

If that quote includes duct, wall and subfloor insulation, it's a pretty
good quote.  If it's just attic insulation, it's way high.  If possible,
use the cellulose blow-in insulation in the attic.  It will seal air
leaks as well as insulate.  On the down side, you have to build sheet
metal dams to hold it away from chimneys and recessed light cans.  Don't
let them block attic vents.  

You can do blow-in insulation yourself.  If you buy the insulation from
most lumber yards, they will loan you the blower to install it.  It
takes two people, one to feed the hopper on the blower and the other to
run the hose.  

If they are going to foam the stud spaces, the skill of the installer is
critical.  It's easy to leave voids when you are foaming something you
can't see.  They drill a hole at the top of the stud space and insert a
hose all the way to the bottom.  Then they withdraw the hose as they
inject the foam.  If the hose hangs up on wires or plumbing on the way
down, you end up with a big cold spot in the wall.  I have torn apart
foamed walls, and have seen everything from really great installations
to a waste of time and money.  

I don't know what your windows are like, but old windows are normally
horribly inefficient.  They used to think stagnant air caused disease,
and intentionally built houses to be drafty.  Air leaks steal energy.  A
case of caulk can save a lot of money.  If possible, have someone set up
a blower door and test the house for air leaks.  You will be astonished.  

You can save a lot of money by blocking off windows at night.  You can
cut rigid foam insulation board to fit the openings of windows and slide
the foam into the window opening after dark.  Gift wrap the foam in
heavy aluminum cooking foil to protect the edges, and screw handles to
it to make it more convenient.  The foam won't hold screws, so you will
need wood on both sides of the foam.  

I hope you have an efficient furnace.  If not, I think you can install a
modern flame retention burner with a smaller orifice.  Heat exchangers
work more efficiently at lower temperatures.  The most efficient furnace
is one that runs continuously during the coldest weather.  With the
added insulation, you should be able to downsize your furnace burner
BTUs quite a bit, even if your furnace is new.  If it is older, a new,
smaller burner will gain some furnace efficiency even without installing
a new one.  

If possible, seal all the duct joints before insulating them.  Duct
leaks in unheated spaces are another big source of heat loss.  

Do you have a target fuel consumption?  It sounds like you normally burn
about 2,000 gallons, which I agree is excessive.  What are you shooting
for?  800 gallons a year?

it's for duct, wall & subfloor insulation. no attic. might do
the attic next year, but we're getting a new roof Monday, with
soffits & ridge vent. it currently has no venting at all.

i would hire someone to insulate the attic. it's really a
scuttle. the house has a low pitch hipped roof, & reaching the
outer edges is a real PITA. it's also really hot up there...

no studs. it's post & beam. even more fun. there are diagonal
braces & also random crossbraces, besides the beams between
the floors.

already replaced 32 windows. the front entry leaks like a
sieve, but i'm having that rebuilt (it's architecturally
significant, and it'd actually cost me more to get a custom
door, which wouldn't match the house, to fit the space)

i replaced a 40+ year old furnace after the first winter here.
that cut my oil bill in half!

somewhere around there, yes. the house is close to 3000
sq.ft., but it's rather inefficient. i'm working on it ;)

Have you considered unvented propane radiant heaters for spot-heating the area
you're occupying at the moment?  I'm talking about the ceramic surface burner
type and not the 'blue flame' type.

I've used that technique for literally decades.  The savings are dramatic.  I
can be comfortable in a 55 deg room in short sleeves if the radiant heat from
a 15kBTU heater is shining on me from across the room.  The added humidity
from combustion is most welcome too.

I've traditionally fired mine from 100 lb portable tanks.  A tank will last
around 2 weeks.  I'm not recommending portable tanks per se, just illustrating
how economical these heaters are to operate.

I couldn't hurt to try.  The heater is typically under $200.  You have a lot
of financial room in which to maneuver.  Thinking about a $10,000 heating bill
makes me have palpations.  Heck, even a $500 heating bill gives me heart burn.
I got lazy last year and bought my firewood instead of cutting it myself. $250
for the dump truck load.  I burned about half of it.

i bought one of those for the sick llama last winter. it's
tiny, but it could cook us out of an uninsulated 3 sided shed
(8' x 16') with tarps on the open side when it was below
freezing outside.

firewood is free here (woodlot), which is good because it's
really expensive to buy. i think a cord is going for $350, cut
& split (and IME not very well seasoned). i want to replace
the stupid fireplace (the one with the right angle bends in
the chimney) with a woodstove... it's just getting rid of the
massive fieldstone blob. hmm. 8 year old boy. sledge hammer.
there's possibilities there ;)

It's not too hot in October.   DIY cellulose is probably a 2 yr
payback. [just a guess- haven't priced it in a decade or so]

Not to mention the difference in comfort of the home. Do the basement
too to minimize the chimney effect. [aka stack effect]

Your contractor has probably got all the dimensions, that's half the
work on doing a heat loss study.    Chances are he can plug in the
expected R values and give you a pretty good guess at BTU loss for
your area.

yeah, it is. i've been up there pulling wire in October, &
February. it's still stuffy & hot. not as hot as mid-summer,
but still not at all pleasant. there's no headroom except at
the roof ridge & even there i can't sit up straight.

stack effect is a balloon construction issue. there aren't any
areas in post & beam that reach from bottom to top of the
house

Are you replacing the whole roof, deck and shingles, or
just the shingles?  If you're opening the roof entirely, that
is *the time* to insulate the attic.  Do soffits first, then
blow in the insulation.  With a closed hip roof, it's dang
hard to do a decent job- too many low spots.  With it
open, it's easy to shield the soffits and such, PLUS, you
can inspect it.  Won't be hot with the roof open.

That's what I did back in 1995.  The old shake roof was leaking when we
bought the place, which was no great surprise with a 4/12 pitch.  I tore
off the shakes and insulated from above.  There was a 2x12 purlin about
6' in from the perimeter, and the original insulator hadn't managed to
get any insulation behind the purlin.  Doing the attic made a huge
difference.  Also, there was an uninsulated return air duct running the
length of the house in the attic, so I sealed and insulated that at the
same time.

All of the infiltration around your sill, through your walls, and
windows and doors- will allow the heated air to rise and want to go
through your ceilings.    Every house is somewhat affected- and the
less insulation you have in the attic, the greater the effect.

Did he comment on the attic- or does he just assume you are going to
do that?   Sounds like a guy you trust- ask him what he thinks.      

I did a lot of detailed heat studies in the 70s including variable
insulation schemes.   Just off the top of my [somewhat addled] head
I have to think that another foot of cellulose in your attic will be
the fastest payback- unless there is sunshine coming through the
walls.  [but then I can't see it from here, and if your contractor has
been around the block and thinks you're doing all right leaving the
attic- he's probably right]

At any rate- good luck and maybe you'll find a natural gas well on the
property.<g>

I had my attic insulated over my old fiber glass batts with that blow-
in shredded fire retardant paper a month ago; 1700 sq ft/$600
installed... can do it yourself with a helper but I definitely don't
recommend a DIY, messy/dusty is a gross understatement.. and you won't
save all that much, the bales are cheap, like less than $10 at Lowes/
Home Depot (they used 40 bales), but the labor is hard, and then you
need to haul the bales and blower yourself and then return the
blower... those guys made four round trips with a full size pick up.
You'll need some bright drop lights too.   When the cost of fuel. etc.
is calcualted they didn't make that much profit.  Two other companys I
found in the yellow pages quoted me more than $3,000 for exactly the
same job...check carefully, lots if rip off artists doing insulation.
I was about to give up and then thought to call a local builder a
realtor friend recommended, he gave me the name of a guy who does his
insulating jobs.  The guy was here the same day, measured and gave me
the $600 quote right there, I told him do it.  The other guys all had
to go home and figure things out and mail me a "proposal".... that's
like the plumber who can't give a price right there for swapping a
terilt bowl... had that happen.

It's been a month now, it's hot as hell this last few weeks and I have
central air, I can tell already I will have a decent savings on that.
I suspect I should save about 20 percent on my heating bill this
coming winter, least that's the percentage insulation guy said.

The rest of my house is well insulated and has double and triple
glaze.  But regardless, the attic is a good place to start, heat rises
so that's where there's the greatest heat loss... that blow in stuff
is cheap and  requires no alterations.

the attic is the only place that currently has any
insulation, & it's 6-8" thick.
all my windows, except the basement windows, are triple pane
gas filled. the unfortunate thing about them is missing the
heat gain i got from the old single panes with storm windows
in winter. OTOH, they really do help keep it cooler in the
summer, even without air conditioning. i still hate them, but
it's too late to go back.

If that's old fiberglass batts it's not nearly enough, in fact the way
it was explaned to me those batts do practically nothing because there
are too many voids.  The blown in stuff  fills in all the voids and
more than triples the R value, and all for very little cost.  My only
complaint is that
once it's blown in you better never think of using that attic space
for
anything.  The guy that did mine built it up more than a foot higher
than the beams, I didn't look until he was done, I was shocked at how
thick it turned out.... it's even piled well over the A/C ducts, so
those are all insulated too.  The first thing I noticed is I no longer
get that huge heat inversion in the evening once the sun goes down and
the outside temperature cools, before all the heat in the attic pushed
down into the house.

You really don't gain all that much heat in winter from sun streaming
in... in summer is when you get a goodly heat gain, when days are
longer and sun hits more directly, just when you don't want it.  I use
shades, I don't want a lot of sun streaming in, it fades all the
carpeting and furniture fabrics.

Older houses were constructed very poorly regarding insulation, if you
have none in the walls I strongly suggest you hunt diligently until
you find someone who will do the job at a reasonable price, heating
fuel is just too expensive these days not to.  Right now is the best
time, no one is thinking insulation in the middle of summer and those
guys can use the work.  If you can find someone who usually does work
for builders they will charge much less simply because they already
have the paid for materials that are left over from previous jobs they
did for builders... I'm almost certain that's why my job cost so much
less than the other prices I was quoted.  And he did a really
fantastic job, anyone could tell he did this many times before... he
brought all the bales on two trips on two separate days and piled them
in my garage, later it made sense that he didn't just buy them.  When
he arrived to do the job is when he brought the blower, again it later
made sense that even though it was marked Lowes he probably glommed
it... he was in and out in six hours.  And  while he was there early
on I got him to loosen his tongue as I'm wont to do and that's when he
told me about how a construction guy he knew kept building materials
in old truck bodies hidden in the woods on his property.  He likely
did the same.

We live at 56 N . The  deep roof overhang and south facing windows are
designed so that the low winter sun hits directly much of the day; and
in summer, when it's higher, the overhang shades the windows after about
10 am.  The  entrance, through a portico , is to a central room with one
wall entirely of glass. The external portico walls, shield the glass
wall from wind-cooling. In winter, sun shines full on the glass wall

sun never reaches the glass wall.

cavity walls (twin walls of brick with a 3" air gap)  and  8" rafters
made retrospective insulation easy to fit. We  replaced all the original
windows (singlepane)  with  low-E double-glazed.

With absolutely no heating at all, the interior winter temperature

Janet, you keep forgetting that Sheldon is a blithering idiot.  Here in
the USA (and Canada) we have an International Building Code.  In that
code, there are several prescriptive paths for glazing.  One path is for
passive solar heat, and one path is for solar tempered heating.  

During our remodel, I added a lot of glazing on the south side of the
house, and substantial thermal mass in the form of tile floors on cement
backer board with R-25 subfloor insulation.  Our daily routine is to
throw some small pieces on the coals to boost the wood stove heat when
we get up at 6 AM.  By the time the fire dies down, the sun is up and
heating the tile floors.  The house stays warm until about 6 PM on
solar, when we light the fire again.  The stove holds a fire all night,
and a massive brick hearth releases heat to supplement the coals before
dawn.  We have central heat, which we only use for backup.  We keep it
set at 60 degrees F. (16 degrees C.) for those times we are late getting
home.  

Obviously, on heavily overcast days we have to supplement the windows
during the day, but even in our marine and notoriously wet climate we
get a huge amount of heat from the sun.  

I love the light.  The house is bright and sparkly all day long.  We
like to decorate with stained glass and other glass artifacts.  When we
bought the house there was a bathroom in the center of the house that
was a depressing, dark hole.  During the re-roof I installed a skylight
that turned it into a conservatory.  We have a Hoya vining around the
light well that blooms 8 months out of the year.  The strong floral
scent from the blossoms acts as a natural air freshener.  The skylight
keeps the bathroom warm all day long in the winter, but over-heats
during the summer, so I made a glazed frame that fits over it in the
summer, and used automotive car tint to reduce the solar gain.  In the
autumn, I just take the frame off and store it until spring.  

We also had a dark central hallway, so I installed a solar tube.  I
suffer from SAD, and tend to extreme melancholy during the dark days of
winter.  The light is very therapeutic.  The house keeps me healthy as
well as heating itself.

Eventually.  I may someday be forced to move into town by poor health or
advancing old age, but they're going to have to haul me out of here on a
gurney.  

I spent several hours yesterday cutting up downed wood and stacking it
for hauling.  I took a break about 4, then went back out and worked
until 8:30.  I feel pretty good this morning.  There's nothing like a
little exercise to help you sleep.  Now if the arthritis would just back

Yes.  The thought of moving into either closer contact in a townhouse or an
OPH is rather daunting.

A friend of mine who had a huge problems with his arthritic knees found that
when he started to eat a small can of tuna for lunch every day he became
effectively symptom free.

my father, 83, just moved into an Assisted Living Community.
his house is a free standing 2 bedroom bungalow with a small
yard maintained by groundskeepers (but he can plant flowers or
veggies) & there is weekly housekeeping available. it has call
buttons in case he needs assistance if he falls or something.
should he get to a point where he needs more active
involvement, like becoming forgetful of medications or unable
to attend to his needs, he would move to an apartment in the
facility where he would be more closely monitored. residents
with more severe end-of-life needs are moved to a nursing
facility in the same complex.
he seems to think it's a good idea. i would prefer he had
chosen someplace closer though.

nope. no fiberglas. it's the old 70s blow-in vermiculite type

it most likely could use more insulation up there, but that's

this year i:
built a barn: $50k
replaced both 40+ year old oil tanks: $5k
am replacing the roof (adding soffits & vents): $20k (100 year
warrantee)
replacing the gutters: $2k
insulating the walls: $10.
i also replaced the well pump & both well pressure tanks, &
the well pump and water heater at the house in NY.
plus i had cancer & no insurance...
there *is* a limit to what i can pay out-of-pocket at one
time.

true, but it feels good sitting in the sun by the window in

my new windows are also low-E & coated to prevent sun fade. i

i'm probably going to go with the guy that knows the building
style of my house. there is a really huge difference between a
balloon frame house (stud walls) & an old post & beam built
house (random crossbracing & diagonal interior beams). most
installers were telling me how insulating a stud wall works &
looked baffled when i asked how they'd work around the
diagonals. if i had a house with stud walls, i'd pull out the
lathe & plaster & put in batt insulation & drywall myself. the
thing many people don't understand about these old post & beam
houses is that the lathe & plaster serves the function that
sheathing does on stud walls. if you remove it & put in
drywall, it'll look pretty for a few years, but eventually the
house starts to rack.

i really love old houses, so i try to learn as much as
possible about how they work... however, when i finally do
find my farm in NY, we'll be building a nice new reproduction
of an old house using modern insulation, plumbing & heating ;)

You can buy sheathing gyp board.  It is normally used for exterior
firewall applications, but can be used for interior finish too.  It has
a glass fiber composite structure that gives it shear strength.

I have no idea what Home Depot does.  I think I bought some grass seed
there once, but that is it.

Yes, I patronize local, independent lumber yards.  Many of my projects
involve materials that the big box stores won't stock anyway.  I have a
lot better luck finding someone who knows what I want at a lumber yard,
and knows that there is a difference between a cantilevered glue-lam and
a span glue-lam.  Prices tend to be better at lumber yards too.  For
hobbyist stuff, I sometimes go to Lowe's.  For instance, Lowe's had some
3/8" thick pine planks that I used to build an enclosure for the
automotive AM/FM/CD in my travel trailer.  Lumber yards don't stock
stuff like that.  

I don't remember what the unit price was for the attic insulation, but
recall that it was dirt cheap.  I think I paid about $800 to do a 1700
sf attic 16" thick, starting from virtually nothing.  There was 3" of
insulation in about 2/3 of the attic, and nothing in the rest.  You have
to over-install a bit because it settles over time.  I live in a mild
climate, so I was shooting for R-38.  The insulation does as much in the
summer as in the winter.  

A couple days rent on the blower was free if I bought the insulation at
the lumber yard.  As DIY projects go, the payback was immediate.  

I would never have been able to do a decent job without the roof tear-
off.  If you are re-roofing, you should really think about insulating
the attic at the same time.  Now is the time to knock holes in the roof
and blow in the extra insulation.  From the sounds of the warranty, you
will never get that kind of attic access again.

The way I look at things, if I can reduce my cost of living now (at any
cost) it is well worth it.

In the future the cost of improvements will be paid off and my monthly
expenses will be lower. Thus in the future I will have more "fun" money.

I'll just say I started doing this about 8 years ago. I've spent thousands
of dollars on anything and everything I can afford to reduce my monthly
bills and these things are now paid off. I have a car which gets 38 mpg. My
electric bill this winter will be about $30 a month. And I have free-to-air
satellite TV. (No natural gas bill, no oil bill, no cable or satellite TV
bill.)

I'm using the extra money I now have available to further reduce my cost of
living.

It is a game for me as to what can I do to reduce or eliminate each of my
monthly bills. (Solar water heater, solar electric, new energy star
appliances, more insulation, energy star windows, etc.)

Note that years ago people told me I was foolish spending so much money on
this stuff. Said I should invest it instead and would get a better return on
my money. Well I'm glad I did not do that!

It's almost always more economical to move to a better constructed
house than to continue year after year putting good money after bad...
it's like painting a bridge, by the time you get to the other end it's
time to begin all over again.  But there is no way to discuss the
economics of home maintenance/improvement intelligently with those who
are emotionally driven... you can spend your entire life chasing your
tail rather than live your life and then you get too old and die...
that house is literally gonna kill you, that's your "any cost".
John Gilmer - 23 Jul 2008 18:56 GMT
There really isn't much to the simple break even calculations.

ASSuming you have the $10k, what productive use can you put it do other an
insulaton for your home?

If the best you can do is get 3% from your bank, then your $10k when
invested in insulation would only have to save your $300/year to justify the
expense.

Even if you could get 10% on your money, you would only have to save 10% on
your fuel bill to "break even."

If you have to borrow the $10k, what is your interest rate you pay?
Compare the interest rate to what you would save in fuel.

This ASSumes that you or your family will stay in the house forever.    If
you plan to sell in a few years you have to decide whether your
"improvements" will be appreciated by your potential buyers.  (Hint:  they
usually aren't.)

In that case you need a shorter "pay off" time.

An easy way of doing the math is to see whether your energy savings would
pay off a $10k loan before you sell the house.

All that said, it's easy to over react the first year energy becomes
expensive.   You might want to do all the "cheap stuff" for this winter.
The "cheap stuff" is mainly stopping air leaks and lowering the thermostat.
You maintain comfort with electric heaters placed where you are actually
sitting.

When fuel oil becomes quite expensive, it pays to compare the cost of
electric heating with the cost of oil heat.   Remember that electic heat is
100% efficient.   A 60 watt electric blanket can keep you comfortable in a
room that's in the 50s.

At the limit you can set your thermostat just a few degrees above that
needed to protect your pipes on a cold night and use extra blankets,
clothing, and electric heat as needed to kept the warm bodies warm.

That's an interesting way of looking at it.  I would guess that $10k
would easily save $1k a year in heating and cooling costs, particularly
in a cold climate.

My wife felt I was going overboard on energy upgrades a few years ago.  
Except for the new entry doors, all the upgrades were invisible.  Then
she started walking around the house in bare feet in the winter without
freezing her toes off.  Then she saw the drop in the electric bill.  
Then energy costs started taking off like a rocket.  Now she thinks I
was a pretty smart guy.

People's habits change with the economy.  In the days of cash cow real
estate, people traded up for more expensive houses.  The *average*
length of stay in a house was just over 3 years(!).  Now, if someone is
fortunate enough not to be losing their house to foreclosure, they have
hunkered down and won't be selling any time soon.

I disagree.  The only reason not to insulate is if you can't afford it.

There are multiple strategies.  Fortunately, older homes often have
provisions for wood heat.  My brother-in-law installed an insert in a
downstairs fireplace last year, and it saved them 50% of their fuel bill
last winter.  Pellet stoves are another option.

i'm in NH. so far the low for this year is -7.6F (not taking
wind chill into account. we have average 10MPH wind year
round, but it gets pretty windy in the winter... & i live 4
miles from where that tornado hit last Thursday)
i have the 10k (if you know a bank that gives over 2%
interest, tell me!). i also have a line of credit, but i'd
prefer not to use it right now.

somehow i think that trying to sell an uninsulated house in NH
with heating oil pushing towards $5/gallon would be next to
impossible... insulation is going to be a buyer priority soon,
if it isn't already.
i am in the process of making this place work for me, but
with an eye on reselling if i find that farm in NY that suits
my purpose (which hasn't happened in the last 12 years, so...)
 
>> In that case you need a shorter "pay off" time.

only if it doesn't increase both my comfort in the meantime &
the selling price in a few years. i'm pretty sure lack of
insulation is going to really adversly affect selling price...
but realisticly, the current recession is going to adversely
affect it even more. i do happen to own the largest
residential/ag zoned chunk of land in the town though, so i
have that going for it (and it can't be subdivided).

i have noticed that many places on the market are houses with
poor insulation, older heating systems, cathedral ceilings,
window walls. people are trying to unload homes they can't
afford to heat as well.

yeah, *not* insulating seems rather silly. caulking is cheap &
air leaks are really minor when you're talking *no*
insulation.
and my electric bills tend to top $200/month in the winter
anyway, & that's before the lovely 13% rate hike that just
went into effect July 1st. electric heaters don't seem like a
cheap option to me, thanks. maybe next year when i install a
wind turbine...

my room is in the 50s already. a down comforter (or even a
polyester fill one) can keep you warm *without* electricity. i
hate trying to sleep in a hot room.

i have 5 fireplaces. the two upstairs are covered, but there's
no reason they couldn't be used. the chimneys are in great
shape (except that damned right angle one, but i can put a
pellet stove in there in another spot, or run in lines from an
external wood burner, which is on the agenda for heating a
greenhouse anyway... if we don't move)

i lived in an uninsulated old house with a barely functioning
furnace (100 gallons of heating oil every 2 days keeping 2
rooms at 40F & shutting off the radiators everywhere else). it
had no fireplace (& my landlord's electric was on my bill...)
i will not do that ever again.
