Question

How much will I save on my gas bill?

I am getting a new Carrier furnace at 96.6% efficient. (2 stage) It is replacing a furnace that is 33 to 40 years old and was at the most 60% efficient.

The highest gas bill the last people who lived in the house got was $428.00.

The last people kept their heater on 75 to 80 degrees during the winter. (I will be keeping it right at about 66 to 68)

Winters are VERY cold here. (NE Ohio) and we are going to be weather proofing some more. (Insulation, cracks around windows etc.)

If that would have been my bill what would the bill be now?

Answer 1

It really depends on the details of your situation, but here's an estimate:

Heat = Efficiency * Energy

~$257 is needed for heat and the rest is lost up the chimney (428 * 0.60)

We can use $ as heat units since we get an essentially constant amount of heat/dollar when we purchase heating energy.

At 96.6% efficiency, this amount of heat will cost you $265 (257 / 0.966)

There are three ways to loose heat from a house:
1) Conduction through the walls, doors, windows, floors and roof.
2) Convection through holes & cracks in the seems and joints (i.e. drafts)
3) Radiation (like a glowing ember)

Conduction is linear with temperature. If most of the heat lost by your house is by conduction, and if you lower your temperature by 10 degrees, and I assume an average temperature of 20 degrees, then

New heat = (70-20)/(80-20) * Old_heat

265 * 50/60 = $220.

Therefore your worst case situation of $428 would translate to $220 with your new operating conditions.

To improve your situation further you need to understand how heat is being lost in your home, then correct the most important causes with the least expense first. For example, weather striping is usually a big payoff since it's relatively cheap to purchase, you can install it yourself and it will have a significant impact on energy loss.

Answer 2

I don't understand why this is considered tacky. Nevertheless, there are always those people out there that will pick at every detail. If your looking to be tactful then simply place a different card or letter in the envelope to those you know that will be needing the hotel info. The website idea is good to but i never had enough time to do that and plan a wedding and also live in the meantime. Another thing you can do is just call those you know will be traveling and tell them the hotel info. My hubby and I didn't do the save the date things. We got married within 6 months of the proposal. But, the rebellion in me wants to say do what you want and who cares. But still, this is your choice. Good luck!

Answer 3

the more insulation the more the savings, several years ago, we did what you are doing now, our heat bills went from $995 per month to about $97 for ten months and thats in the syracuse ny snow belt. each home is different, you could get great savings, if you pay strong attention to whats happening in and arround your home. close off the doors, dont keep opening them when theres no reason, and dont run the vent fans longer than necessary, you`d only be pumping your money out side keep the windows closed and insulated too. good luck, the money that you save is yours in the first place not the utility company`s, after 3 years you could buy a motor home and get a real vacation with all of the extra $$ good luck

Answer 4

I would think that it should be cut at least in half. If not more.
