electricity use???

I believe I have it but could be wrong....

A 100 watt lightbulb would have to burn 10 hours to use a KWH (? cents) right?
So, if I have a heater that is 2400 watts, it would use 2.4KWH in one hour (at max)?

Trying to figure out the savings of shutting off the oil heater and using the electric on demand heater til heating season comes back around. Only thing it would be heating is shower and hand washing water for 2 people. Heating oil is $4.40 a gallon here.

Thanks, Dave
 
You shoulda seen my bosses face when it sunk in... I explained to him one time how if a cust.'s server was replaced it with a newer, faster, more efficient one that the electricy savings over the next year would have saved them about half what the server cost in the first place.
 
Dave there is a 125000 btu in a gal, so if your
furnace is 85% efficient that's 106,000 btu of usable heat per gallon . there is 3415 btu in a
kilowatt . this is where you start your comparison .
it will take 31 kilowatt to equal a gallon of oil
with this comparison.
 
Thank you dblair.
At about 10 cents a KW HOUR that comes out about equal to 3.10 oil. 10 cents here, but maybe 19 cents some places.
Now would you do the same thing for natural gas for house heating?
 
Dave...that on demand heater only spins the meter when you turn on the hot water...if its still cold better leave the oil burner runnin tho.
 
The modern devices are often much more energy efficient with them being more so to come in the future. Ex: solid state vs. hard drive.

I just replaced a 17 year old television set and had no issues with the old set ceasing to function as the new one will pay for itself over time through energy savings. About 50% consumption compared to the old one, even with it being much larger.

We shut the heater (main radiator supply valve) off as soon as we get a day with 50 degrees and just use the wood stove in the living room for the evening.
I'm taking all this in and working over it like a monkey doing algebra.....

Looks like it'll cut the bill about in half by shutting the boiler off. I'll read the meter and try it a month.

Thanks,

Dave
 
How much TV do you watch? Also if you use electric heat, saving power in the TV doesn't save you in the winter because you have to replace it with you heating appliance.
 
The comparison is not in how much electricity it takes to equal a gallon of oil, but in how much LESS energy is necessary to heat just the hot water being used vs. running the whole-house boiler.

Wish we were getting 50 degree days around here. Right now it looks like we've got another week of good maple sugaring weather. 40's during the day, 20's at night...
 
there are 100000 btu in a therm in a 90% furnace you get to keep 90000 a very good rate . the electricity is the same as above . Therms are generally a lot less you will have to check your own gas rates for that .
 
Until I bought a Roku streaming video player to transfer video from the Internet to my old television it would go several days each week without even being turned on.

After the old set quite It was a month and a day before I replaced it.

The new set is turned on several hours each day now as I stream Netflix movies to it so that I don't have to watch them on my computer monitor.

A lot depends on the weather outside as the nicer it is the less I watch. Cold, snowy, rainy the last two days. Currently 7:23 p.m. and haven't had the set on all day but will shortly change that as I pick out a movie to watch.

The new set will pay for itself via energy savings if I watch about 2 hours per day and if it lasts as long as the last set. Whoa! That isn't accurate as I didn't consider the energy savings while in standby mode--so even less.
