propane or natural?

Gee, would have been nice if I stated that. Natural Gas firreplace. I have to say, If I were building, I think I would put in Propane for heating, been seeing those commercials and they make me wonder ....

I was also wondering, what type of fireplace gate do you buy? mine fireplace puts out so much heat that I worry even the gate will get too hot and my lil' daughter will touch even that and get a lil' burn, or the dog might sniff it OUCH!

For a natural gas fireplace that puts out 28,000 btu/hr: assuming 90% efficency and gas at $1.26 per 100 cubic feet:

(28,000 btu/hr divided by (103,000 btu per 100 cubic feet)) x $1.26 x 1.1 efficiency = 38 cents/hour to run at rated output.

For propane fireplace that puts out 28,000 btu/hr: assuming 90% efficiency and propane at $2 per gallon:

(28,000 btu/hr divided by (86,000 btu/gallon)) x $2 x 1.1 efficiency = 72 cents/hour to run at rated output.

Insert your actual price of gas and propane for more accurate price calculations. Note that propane may be as much as twice the cost for natural gas (don't believe every commercial that you see).
