Yesh, I was thinking to myself that what about how the similiarities would be of the temp I burned the propane at and compare it to the coal ... and then something came up and I forgot all about it. So thank you for bring this up. I did the numbers and as you expected it heavely weighs in the favor of coal vs propane/electric. Now I have something to go back to the boss (my wife) and say here are the numbers? :D Let me know what you think of these numbers? Thanks


Kwatt hours came to 16556, so x 3412 = 56,489,072 so / 26,000,000 = 2.2 ton + 1.6 ton = 3.8 which sounds about right from the estimates. 3.8 x 214 = $813.2 for 6 months of burn. In conclusion, $2684.85 - $834.6 a savings of $1850.25 over 6 months. yow. Granted, the savings won't be that great because my electric isn't just for heat over that time span, and I probably won't be able to heat the 1st floor totaly so I would say though, $1000.00 to $1400.00 wouldn't be that far out.

As for the electric, do you know how many kilowatt hours you used for heat? Assume 3,412 btus per kilowatt hour electric heat and go from there. I think you will find that the savings with coal are substantial.

Whats' the pipe leading from the pressure relief valve through the wall? Does the insulation not melt or catch on fire being right up against the stove like that? What type of pipe did you use for your coil and did you roll it yourself?

The pressure relief valve runs through the wall and empties outside in case it needs to open. The insulation on the pipes did melt a little up against the stove but it wasn't was major problem. My killer rabbit did more damage noshing on it. I custom designed the coil and had it manafactured.
