Nick, according to my calculations, there 5.3 cubic inches of water in
a foot of pipe, that is equal to .0229 gallons. At 8.33 pounds per
gallon, that is .191 pounds of water per foot of pipe.

We all seem to agree on that.

Assume 10 feet of 3/4" pipe that sweats that is 1.91 pounds of water.

And that...

To warm that from 40 degrees incoming temperature to 70 degrees, at
1 BTU times 30 degrees times 1.91 pounds = 57.3 BTUs.

Yes...

At 8 cents per therm (100,000 BTUs)...

You can buy oil for 8 cents a gallon? :-)

the cost savings gained by leaving the insulation off is.0045 cents
every time you have to warm the water in the pipe.

I make this 0.115 cents at $2/gallon.

If the people in the house use the water 40 times each day, the total
savings per day is .183 cents per day...

And 4.6 cents/day.

Times 30 days per month is 5.49 cents (per month)...

And $1.37/month.

Nick, that is not enough to worry about. Even if you allow for
inefficiencies, it is still less than 10 cents per month. Nick,
that is not worth the time I just spent on it. Or do I need to write
that into a BASIC program to get the point across to you?

You might check your math for glaring errors and read more carefully.
I said this savings is small compared to warming an active pipe with
condensation, which might save 20% on a water heating bill.

And you might modify your arrogant attitude and be more polite.

Apologizing is optional.
