We're thinking of getting a good quality gas-log for our fireplace -- the
The fireplace store couldn't give any estimates of operation cost -- just
BTU output, which was 90,000 for the one I'm looking at.
Can anyone give me a ball-park figure of the cost of operating these logs? I
guess per-hour would be the best way.
1 therm = 100,000 BTU, so the gas log you're looking at (90,000 BTU/hr)
consumes 9/10 therm per hour.
Call your gas company and ask how much they charge per therm. Multiply by 9/10
and you'll have your hourly cost.
When I bought mine a number of years ago I think I figured the cost at 50
cents per hour. Not many things you can do for fun at 50 cents per hour.
Notice I sad fun. It is not a savings type of thing.
Seriously, find the input rating in BTU, call your gas company and find out
the estimated BTU per cubic foot then do the math for yourself.
The only thing I do professionally is window treatment installations.
Millions of vented logs are in use in fireplaces across the US. These tried
and true log sets have been sold for 20 years or more, and are still the
most popular type. They are available in lengths from 12" to over 60"
(that's a big fireplace !). Vented logs are the most realistic wood fire
substitute made, and are available in different styles and finishes which
resemble oak, birch, hickory and many other wood species. This realistic
beauty comes at a price; vented logs are also the least efficient of the
three types. They consume for 50,000 to 90,000 BTU/HR of Gas which costs 40
cents to 80 cents per hour (Natural Gas) and 60 cents to $1.00 per hour
(LP). The efficiency is rather low, meaning that only 10% of this heat is
returned to the home. The rest goes up the chimney, much like your old wood
And that is why I replaced mine with a gas insert. Not quite as pretty but
extremely effiicient and still useful when an ice storm causes a 3 day power
outage. The circulatory fan won't work but they still start up and giveoff
lots of heat around it. There is a small risk though of damaging the fan
motor when there is no power for an extended period according to the

Natural gas or propane?
Here are some propane numbers so you can do the formula once you know what
the price is. The idiots at the store should know this stuff.
BTU per gallon (vaporized)
BTU per pound (vaporized)
