How much does a therm of natural gas cost?
A therm of natural gas sold to me for home use by Questar Gas cost 92 cents. The cost of a natural gas varies depending on what state you live in. Utah has the lowest cost of natural gas.
Is natural gas cheaper than propane to use for home heating?
Yes, normally. To compare cost value you must know price per therm (a therm = 100,000 btu). Natural gas where I am costs, as of 1 Oct 12, $0.50 USD per therm. Propane costs $2.69 USD per gallon. 1 gallon of propane has a weight of ~4.2 pounds and 1 pound of propane yields 0.21661 therms or ~0.91 therms per gallon. That makes the price per therm $2.96 USD per therm or almost 6 times…

How much should it cost to heat 1 gallon of water from 50f to 140f at a natural gas price of 2 per CCF?
I had already done the calculation for raising water from 60f to 125f using a cost of $1 per therm. This should give you a rough idea. Q=c*m*(t2-t1), where, c=specific heat of water (1 calorie/gram) m=mass of 1 gal of water = 3780 grams t is in degrees celsius: 60f-125f ==> 15.5C-51.6C Using those values, Q=[1 cal/gm][3780 gm/gal][51.6C-15.5C] ==>136458 cal/gal There are 25200 Kilicalories/therm, so 1364548 calories = .005 therm. So, at $1/therm for natural…
How much cheaper is natural gas heating than oil heating?
== == It depends on where you live and the cost of the fuel. You have to convert to the heating value of gas and oil, factor in efficiency, and then compare the cost per BTU's. For example: Determine the cost of gas vs. oil in your area: For example, heating oil in Seattle is $4.10 per gallon while gas is $1.09 per therm. Next, calculate the cost of fuel per MMBTU's. Knowing that heating…
How much natural gas therms do we use?
It is easier for the standard of measurement of Natural gas to be measured in cubic feet. That is how the Gas companies measure the amount of gas produced, used, moved...etc. Since a therm is a measurement of energy we can approximate the usage like this: The energy contained in a a cubic foot of gas varies. Therefore an exact Therm usage value will be hard to come by. (It would be easier if there…
How to convert Therms to MMBtu?
I was just researching this same question today. Here's what I found hope it helps. 1 Therm = 100,000 BTU 10 Therms = 1MMBTU ( Million BTU's ) Therefore to convert from MMBTU to Therms, multiply the MMBTU figure by 10 to get Therms. Note: Therm to BTU conversion is based on the amount of energy obtained from burning 1 Therm (100 cubic feet of natural gas). This value is not exact, but close, and…
How can i find how much it cost to run a air heat pump in central Illinois compared to a gas furnace?
Find out what you pay per kWh, then determine the wattage used per hour of run time of the heat pump. Then multiply the two for cost of runtime per hour. Do the same with your cost per therm (100 cubic feet of natural gas). Determine the input rate of the furnace in btu per hour (100,000 btu input would equal 1 therm used per hour of runtime). Multiply the two and you have your…
What is the difference in cost for heating water with an electric water versus a propane water heater?
For gas and oil water heaters, you need to know the unit cost of fuel by BTU (British thermal unit) or therm (1 therm = 100,000 BTU). Then use the following calculation: 365 X 41045/EF X Fuel Cost (BTU) = estimated annual cost of operation http://apps1.eere.energy.gov/consumer/your_home/water_heating/index.cfm/mytopic=13010
How do you convert therms to cubic meters?
The "therm" is a unit of energy often used in connection with various methods of home heating ... gas, oil, electric, etc. 1 therm = 100,000 BTU = 1.055 x 108 joules That's the easy part. The next question is: How much energy do you get by burning a cubic meter of natural gas ? The references we found on line listed the following answers (in mega-joules): 37, 40, 37, 19 to 56, 37 to…
