If I use my 60K LP burner (NB 7334) to heat 15 gallons of 56*F water, my costs for LP are about 6 cents a pound.

To raise the water temp to 175*F, what would my LP consumption be?

According to the table on Brewmation.com, if one uses water heater elements in the HLT, raising the temp of 15 gallons from 70 to 160 takes 36 minutes.

If I want to start at 60, end up at 170, that's an increase of 20 additional degrees. That would be an increase of roughly 22 percent.

Using a 6000watt element, this increased time would be about 44 minutes total. At 6.3 cents per KWH, (6KW x 6.3 cents x .75 hours) electrical costs would be less than 30 cents! Am I calculating this correctly?

I can't imagine that using a burner would come anywhere close to this cost.

Any thoughts/concerns/obvious mistakes?
