Generally indoor humdity is insufficient in the winter, especially or
at least iirc if one has forced air heat. Unless your situation is
different, iIt would be better to have a humidifier connected to the
furnace, because that could give adequate humidity all of the time.
The higher humitidy is good for wood furniture (that is, very low
humitidy is bad for it, leads to cracking), good for some people who
have certain respiratory problems iirc, and it also makes one feel
more comfortable, so that the thermostat can be set lower for the same
feeling of comfort.

But evaporating the water takes about 10X more heat energy
than you save with a lower thermostat setting.

A) This is not a situation where the person is evaporating water just
so she can heat the house. The water has already been evaporated,
and she wants to gain the side benefit of having that warm air and
humidity inside the house.

B) I think your last two lines above are inaccurate. I think it
takes 10 or so times as much heat to raise the temperature of water
one degreee when the water is also changing from liquid to gas, than
it does to raise the temperature of the water one degree without a
change of state. But the thermostat setting that is possible with
higher humidity is lower by more than one degree. I would say it's
possible to achieve the same degree of comfort with the thermostat set
5 degrees lower.




Although it was undesired, I have a lot of experience related to this.
When I lived in NY, I had a landlord who fancied himself a plumber.
He *was* capable of simple repairs, and of installing water-powered
trash compactors, and he had done those things for a living for some
years before buying my building and some others; but he was not
capable of maintaining the oil furnace steam heat that this 6-story
49-unit building had, (nor did he understand the water pressure issues
for a 6 story buidling on a hill.)

Because he fancied himself a plumber, he only called a skilled
repairman as a last resort. Consequently, we spent a lot more than
the typical number of days each winter without heat. I learned how
to "heat", that is, make feel comfortable, my 6-room apartment by
boiling water on the stove. Although I don't have numbers regarding
how much gas I used to boil the water for an hour (and I don't even
remember exactly how long I did so each time) I'm pretty sure the
effect on my comfort and my roommates' was far greater by boiling
water and increasing the humidity than the same gas would have been
just warming the air in the apartment. I believe there were a few
occasional stories on the news during the 12 years I lived in NY that
specifically said boiling water was far more effective. (and safer
because less gas had to be burned.)

Now that I own my own house, I bear a good portion of the blame any
time the furnace doesn't work. Never theless, there have been quite a
few days like this. I've used the shower (and a stoppered tub,
which I watch carefully to make sure it doesn't overflow) to raise the
humidity, and it takes no longer than running the furnace (up to a
point. I can make the house as hot as I want with the furnace, but
increased humdity can only do so much.) Remember to remove the bar
of soap before running the shower. I've wasted some soap when I
didn't remove it.

I've also boiled water on the stove in this house. I use a pot that
holds more than a gallon.

Both methods have had enormous effects on how comfortable I am when
the temperature in the house is 65 or 63 or even lower. That is, I
feel fine at those temperatures.

The OP only reported condensation on *some* of the windows in her
house, that part of the house where the dryer is, and that dissipated
quickly.

She doesn't have excess humidity and she's not going to hurt anything.

As to excess lint in the air, I've been doing this for 20+ winters,
and I haven't noticed anything. The dryer has a lint filter and my
diverter box has a second lint filter, that fills much more slowly
than the one in the dryer. Her device has some sort of filter too.
I clean my filters and I'm sure she does too.

I've never heard of a house fire where the air burnt because of the
lint in it, or where lint in the air was noticed to be burning. I've
never heard of a house fire where dust on the furniture or the mantle
was listed as one of the causes of the fire, or of the fire's
spreading. Maybe CDET22 can refer us to evidence of this.

But I can see the dust in my air when the sun is bright and shining in
the window, and it's no thicker in the winter than the summer, when I
vent the dryer outside and there is a breeze exchanging indoor air
with outdoor air.
