Guys, my january bill was flipping ridiculus. 603 M3. I have a tankless water heater, and have a timed thermostat. During the whole of january the furnace was totally off from 7Am to 6PM. I had to go outside and check the meter, and the meter was bang on from what I was charged. The worst thing is that my parents were in a contract from direct energy for 44.5 cents per m3. Starting march the contract is done and am going back to enbrige. Anyone have ideas as to how we were able to use 603 m3? We do not have a gas stove. Just a tankless and a high efficiency furnace.

How big is the house? What temperature do you heat the home too?

And you had the furnace turned completely off? What temperature did it go down to while you were gone? We turn ours down quite a bit at night and it still comes on during the night.

House is 2400 Sq Ft.

Hey, the furnace is set to 14 degrees from 7:30 to 5:30. During the coldest days of Dec and Jan the Temp Dipped down to around 15 Degrees, which is why I had set it to 14.

So

Wake: 18.5
Leave: 14
Return 18.5
Sleep: 17

Maybe I will monitor the gas meter during the day when we aren't using ANY gas for a period of a couple hours. Maybe we could have a gas leak that no one smells? lol.

1) According to our January gas bill, we used 723 M3 for a 3100 sq/ft home (4500 sq/ft including basement). Does this seems right considering the size of the home? We set thermostat to 17-19 degrees (never higher).

2) What appliances/factors use natural gas? Any suggestions of how to reduce consumption?

thanks

I tried to find a thread about thermstat and timed settings, but wasn't able to find out. Basically the idea is to have the temp as low as possible during the day and night when you are not home or sleeping during the winter. Maybe people should post their thermostat timer settings and temps.

Very similar to our settings (except opposite as we do our 14 at night since need it cool to sleep). We use almost 9 m3 per day for a 1600sqft home, gas water heater. It will very much depend on the size of your house so while yours still does seem a little high, it does make sense considering your house is that much bigger.

Very similar to anoopi in the amount used per sqft, so it is roughly proportional to the size of your home (which obviously makes sense).

Other factors will be the age of your home, or more accurate the condition of insulation, windows, doors, weather stripping, etc. Along those lines, the types of windows, doors. If your basement is finished and / or properly insulated and sealed (which most homes are not tape sealed in the basement). Flooring in basement (finished, unfinished, insulated). Location of thermostat (hopefully on interior wall) as near front door may cause it to go on due to door opening. Attic access sealed (lots of heat loss there). Water heater set temperature.

Usually just furnace and water heater use gas, other than any appliances that are obvious if you have them (gas stove, BBQ connected to gas).

Our latest bill shows usage from Jan 28 to Feb 28 at 192m3. This is for an 1800 sqft 2 story semi with a finished basement. We're the south side semi which makes a difference and also have all new windows (which cut our gas bill by 25%). Our thermostat is set to 21 most of the day and goes down to 17 for 7 hrs overnight. Gas water heater as well with 2 teens. Our bill also shows we have only used $305 worth of gas to date this year. :)
Thinking seriously about the 4 S's...Sun, Sand, Surf and ... Booked for Sept in Mexico and booked Samana DR for Jan!

Wow! You have me beat. We used 270m3 for the same period, slightly smaller home (1600 sqft) with finished basement, gas water heater and furnace, single detached home (not much south facing). Maybe we need new windows also. Guess it is a little warmer in Niagra Falls so wonder how much that is the difference.

I think temp wise, we've been about the same, give or take a few degrees here and there. The windows made and still make a big difference for us. They are top of the line windows that we got a great deal on at the time. We were on a gas contract the yr before the new windows and the yr of so price was the same. The Enbridge weather calculation was that the yr with the new windows was actually 5% colder yet we used 25% less gas. I will say that we purposefully bought the south side for solar gain in the winter as we face east/west. I get full sun more than half way through the house at any given time of the day through the winter months. My kitchen is at the back of the house with an east exposure and my living room is at the front with a west exposure... Now the kicker, we still have the original builders furnace in the house that is 22 yrs old! We certainly can't justify putting a new furnace in at this point until we absolutely have to as we seriously doubt we'll see any real cost savings. :confused:
