How many therms (natural gas) do you use per day (per month)?

[clams_casino]

Possibly in south FL.

[clams_casino]

We used 30 therms in both July / Aug (hot water & furnace pilot) - US.

[daestrom]

My bill states 27 days in the last billing period. 158ccf is the amount of natural gas that I am being billed for. Is that the same unit you are referencing?

[hchickpea]

We pay $11/mo tacked on to the power bill, but were able to get one of ours deferred by the health department (we have two power drops, one on each side of the road.)

[Charles G. Hill]

For lo, Donna Ohl hath proclaimed:

I am billed in dekatherms, and assuming 10 therms to the dekatherm, my last bill (over 32 days) was for 5.96 Dth, therefore

59.6 therms, or 1.86 therms per day.

Background: small 1940s home in Oklahoma, mostly average temperatures for the month, gas furnace and water heater.

Incidentally, the meter reads in Mcf; a BTU factor is applied based on the quality of the gas received. The actual meter reading was 5.8 Mcf.

During the summer readings have been in the 2-Dth range per month, about 0.7 therms per day; however, this past October I replaced my

22-year-old water heater with a new tank, which should theoretically use a bit less gas than its predecessor.

At last! Someone using a rational energy unit.

In fact, the BTU is one of the best of the British (actually now just American) units. It's 1055 Joules, but as a rule of thumb you can think of it as a kJ.

But having different units for every single energy source is just nuts.

Who else uses the therm, roughly .1 GJ, but the U.S. Gas industry?

lists natural gas prices in MMBtu, where MM=1000*1000 or one million. That's pretty nice, just about the same thing as a GJ, so we and the Canucks can actually think we are talking the same language.

[And MMBtu ~= MCF, so we have a three-way match]

It's fairly useful for energy calculations when everything else is in SAE, or whatever you call not metric. Insulation (in the US) is rated in BTUs, square feet and degrees F. The amount of specific heat stored is 1 BTU per degree F per pound of water. Now if you mix in any metric, it all becomes completely unwieldly. Either all metric or none at all makes the most sense. I think we've had some rockets that smacked Mars because of that.

Jan use: 220 therms (old masonry house, upstate NY) Annual: 1450

In the winter, we pretty consistently run about 0.2 therms per degree-day.

Last year we used a total of 71.5 MCF (734 therms at 10.27 therm/MCF). That's an average of 61.2 therms/month. Highest monthly usage was 17.4 MCF (178.7 therms) for 1/23/2007~2/22/2007 for which the average temperature was 22 deg. F. Most recent monthly usage (33 days:

12/21/2007~1/24/2008) was 13.3 MCF (136.6 therms) with an average temperature of 32 deg. F. In the summer months the usage was 1.2 MCF (12.3 therms) per month.

This is a 1750 sq. foot, 53 year old brick and stone ranch style house with fairly new double pane windows. We are in Pittsburgh, PA. Gas is used for heating (forced air), hot water, and cooking, for two people. We keep the thermostat at 58 degrees at night and 68 degrees in the daytime in the winter.

[Anthony Matonak]

I live in Los Angeles, California and I can't recall the last time I needed to fire up the heater. This winter has been fairly warm with an average of around 60F. I'm hardly home enough to cook even if I did have the inclination and I don't have any teenagers that take incredibly long showers. This probably explains the low gas use. :)

This just shows how useless it is to ask the whole world how much gas they use. Someone in Fargo is going to need a little more heating than someone in Key West. :)

Wikipedia isn't bad on the use of "therms":

For measurement units, it says: Natural gas in the U.S. is measured in CCF (100 cubic feet), which is converted to a standardized heat content unit called the therm, equal to

100,000 British thermal units. A BTU is the energy required to raise one pound of water by one degree Fahrenheit. A U.S. gallon of water weighs 8.3 pounds. So, to raise a 40-gallon tank of 55 °F water up to 105 °F would require 40 x 8.3 x (105 ? 55) / 100,000 BTU, or approximately 0.17 CCF, at 100% efficiency. A 40,000 BTU (per hour) heater would take 25 minutes to do this, at 100% efficiency. At $1 per therm, the cost of the gas would be about 17 cents.

As for usage ... it goes on to say: Water enters residences in the US at about 10 °C (50 °F) (varies with latitude and season). Adults generally prefer shower temperatures of 40?49 °C (105?120 °F), requiring the water temperature to be raised about 30 °C (55 °F) or more, if the hot water is later mixed with cold water. The Uniform Plumbing Code reference shower flow rate is 2.5 gpm (gallons per minute); sink and dishwasher usages range from 1?3 gpm.

You can also use bubble wrap over your windows.

It's been frigg> For the past billing cycle, I used 5.96 therms per day. Last year I

For those who don't know, "friggin" is local slang for ice fishing on lake Michigan :-)

[Angelo Campanella]

Our recent (Ohio) gas bill was $248 for 187 CCF = $1.33 per CCF.

Well there ya go, I had no clue? Who woulda "friggin" known?

[Bill Stock]

Not sure what a Therm is, but we used 600 cubic metres last month and that was an estimate. So the actual number was probably higher.

[Bob F]

When I had a furnace with a pilot light, I always shut it off except during the heating season.

[Bob F]

Based upon the "heating value" of that month's gas, I assume.

[JR Weiss]

Seattle, heat & water, 2800 sqft house (about 1800 sqft heated): My last bill shows 3.8 therms/day last month and about 2.5 therms/day average for the past year.

Since San Jose is considerably warmer than Seattle, I suspect you could get close to 2 therms/day down there...
