Not sure that is 100% true. There is lots of waste
heat, but the refrigeration system is expending
energy pumping heat out of the refrigerated area,
just so it can gradually be absorbed back from your
heated home. At the end of the day, does all of the
energy that the refrigerator uses really show up
as waste heat in the room?

Of course it does. If the refrigerator is consuming
an average of 500W it delivers an average of 500W.
That's just basic physics.

There is a "cool" exception, but this was not included
in the original question.

During the heating season take liquid tap water in a
container, freeze it in the freezer, and throw the
resultant ice out doors.

In addition to the power needed to run the
refrigerator you will have extracted some of the heat
in the water.

Cool huh!

My head hurts.

What's wrong with the regular heating system?

It heats the whole 3000 sq.ft. house instead of the 250 sq.ft. bedroom.


But what's regular?

Fuel type... Gas, Oil, Electric, Kerosene, Waste Oil, Wood, Corn, Wood

What type of heat? Forced Air, Hydronic, Heat Pump (Geo or Air source),
Radiant, Convection, etc???

Which is regular?

Regular is like saying NORMAL. What's normal?

Normal is just the regular system. duh! ;-)

It depends on your definition of waste.

Whether you can make good use of the waste heat is another matter.

Depends on where you live in the country. While my figgerin' could
be wrong, at around $0.08/kwh, (Chicago area), I calculated that
natural gas would need to be in the ballpark of $2 per therm in order
for electricity to be competitive.

You're correct, and natural was up to over $2.50 a therm last winter.

So input that into a 80% furnace and we have trouble.

While my memory is not flawless, I don't recall my rate getting much
over $1.25/therm last winter. (and I already factored in the typical
80% efficiency rating).

FWIW, I did some more figgerin' and came up with $1.92 as the break
even point at $.08/kwh, assuming 80% efficiency (this is all exclusive
of delivery charges, taxes, etc.). I understand that electricity
prices in other major metropolitan markets are about double mine, so
the break even price would be closer to $4.00/therm there. The bottom
line is that, barring any major technological breakthroughs in
electricity production, it's not likely that electricity will be
cheaper than gas as a source of residential heat anytime soon.

economic sense was in taking the steak that they were selling for $3+
per lb, expending the extra labor to grind it, only to sell it for
under $1 per lb.

Of course, the heat generated by the grinder probably offset their
cost to heat the store (just trying to stay on topic ;-)

When I was a kid, in the Pacific Northwest, electricity was $.02/KwH.
My Father, the Banker, was a Depression KId, and had a fetish about
turning off the lights, in rooms that were unoccupied. He would
get very angry at us kids for "Wasting Electricity". In 7th Grade,
I wrote a Paper for Science Class on the efficency of an "All Electric
House" which we lived in. Got an "A" on the Paper, and after my Father
read it, he quit ragging on us kids about the lights, but only durning
the winters. Summers were still a bit of a hassel........

Not every power supplier burns natural gas for it's source. Our electric
rates are much cheaper since they burn coal in this area.

I'm also not saying that electric is ALWAYS cheaper all over the US or
saying that it stays that way. (we were talking about 8 cents/kw vers high
priced natural and using a heat pump to save money)

Last year our natural price was over $2.50 per therm while electric was
under .08 cents/kw. Now put that in your pipe and smoke it! :-)

I have a small propane heater for sale. 150,000,000 BTUs


Not likely. 150 M BTU per hour?? That's on the order of 44 MW. It would
go through a 150 lb bottle of propane in just minutes (if you could even get
enough flow rate through a standard propane rig to supply it).

Even 150,000 BTU per hour is more than double a full-house furnace.

A friend of mine in Wilkes-Barre, PA owns a large Victorian home and
he tells me his aging boiler is rated at a whopping 425,000 BTUs (I'm
taking him at his word).

His home isn't well insulated and given his excessively high gas bills
I suggested he arrange for a home energy audit, which he tells me he
has done. I also suggested a new (and presumably much smaller) boiler
is likely to be one of the key recommendations and I'll be curious to
learn just what they have to say about his current system.

Which answer below is correct?

1 They all create different amounts of heat.
2 A & B are equal, C & E are equal, but D produces more heat.
3 A, B & D are equal and C & E are equal, but C & E produce
more heat.
4 (A,B,C,D & E) All create the same amount of heat.

Correct, but incomplete, answer (have renumbered answers) is 4

But complete answer is:

A,B and D produce more radiation heat
C less radiation
E most heats buy convection

Therefore, if you are sitting exposed to sources A, B and D, you
feel warmer with the same power (sounds strange ?) as of C or E.

If you are interested ONLY in heating a room, answer 1) is ok.
But if you are interested in heating people (for example, outdoor),
sources A, B and D are very efficient options.

Let us put it this way: A,B and D are most efficient in delivering
the same amount of power of C and E, but where you need it mo on
your body.

Example: a keep 64 F at home. When I am walking around it is a
comfortable temperature. But when I sit down, I start to feel a
little cold.
Solution: a 150W halogen lamp with reflector pointed in my
direction. 150W is not that much power, but you have to compare it
to your body heating power (about 100-200W), so if you could
deliver that power to heat yourself and not the walls of your house

A big house ?

4000 plus square feet, 12-15 feet ceilings, big picture windows, and old on
top of it.

How would you like a $1000 plus monthly heating bill?????? Not me!

hehehe We replaced a 350,000btuh steamer a couple years back with
another the same size. Huge, old house. I think it was built around
1910.


Biggest I've seen is a 1 Million Btu boiler for a commercial building.
2" Black Pipe Natural gas main and manifold!

Had the original pilot valve, gas valve and separate regulator on it, that
had all been under water.

Can you say... scarrrrrrry?

Light is not heat. Get over it.

I hope your sound system noise doesn't heat up your room too.

Geeesh. Go back to school you energy dummies. Your eyeballs are all
burned from illumination being converted to heat in your brains.


Measure the current that the sound system is using, then measure the
voltage. That's energy being entered into the room.

Amps times Voltage = Watts

1 Watt = 3.413 Btu (That's HEAT)

WHETHER you want to believe it or not.


But let me ask you this, if it doesn't create heat... why do I have to cool
"cable equipment rooms" in the middle of winter?

I mean, there is nothing in there to heat the building, except a bunch of
receivers.... so where is all the heat coming from?

So lets see how long you can hold a 500 watt halogen bulb in your hand after
it has been burning for ten minutes.

And of course, loudspeakers never overheat and burn out from supplying them
with too much wattage...
