How much does it cost to run a 10000 btu vent free stove for 24 hours?

Answer 1

That depends on the how much your gas costs and what is the desired temperature and how much effort it is required to maintain the desired temperature.

If we assume your went free fireplace has no thermostat and no regulator for the intensity of the flame we do our calculations with maximum values.

A typical vent-free fireplace consumes 26000 - 40000 Btus (british thermal unit) per hour. Assuming the unit operates at peak operation the entire time, it would only cost 36 cents an hour to run the appliance. 24 hour period would then cost 8,64 dollars. (Price of the gas by year 2006 rate).

However most vent-free units have thermostats that lower the heat when they reach a pre-set temperature, so these appliances do not operate at peak output all of the time.

1 standard cubic foot (=0.0283 m³) of natural gas yields ≈ 1030 Btu.
1 cubic meter = 36395.76 Btu. So 26000 btus 0.102 dollars/h. 0.102 dollars x 24h = 2,43 dollars. Naturally no reseller will ever sell the gas with stock prices, usually a certain profit percentage is added. Let's assume the store takes 30% profit: then the cost per hour would be 0,1846 and 24 hours = 4,43 dollars.

However comparing the price to the 2006 rate, and knowing the prices have been rising, I assume I have failed to implement the correct expences etc. on the profit margin. So I suggest you go ask how much your local seller asks for a cubic meter of gas and calculate yourself.
