the cost of coffee?

[Mike90250]

I've got about 200w of "base loads" that are always on, including Ozone bubbler for water tank, aerator for filter tank, couple night lights, one of 3 fridges always running, laptops, water heater brain, garage door receiver.
Some you just can't get rid of.

I Went A Round THE House And Unplugged THE WI the treadmill the coffee maker two night lights a laptop cord that has not been plugged into a laptop but has a small light on its transformer and an alarm clock.

I have the new consumers digital electric meter. In the nighttime hours between midnight and morning our average kwh went from .38 .47 per hour to .27 .37 or very close. I of corse do not know how much any one was suckling but they all add up. Oh yeah my daughters electric piano as well.

So your phantom loads are around 300W? Each watt is adding 3/4 KWH to your monthly bill. You are on the
right track, but have a long way to go. Get your KILL-A WATT meter and check everything, including stuff
wired in, like furnace control trans, doorbell trans, etc. I had a hundred such things all adding up to 300W;
with considerable effort reduced it to 50W. Some things I couldn't undue were motion detector lights, GFI
outlets, garage door radios, and a couple clocks; some things were reworked for a 70% reduction. Bruce Roe

That thing is also a phatom load. The timer and electronics draw for the whole day. It may only be a 5 or 10watt draw but it's still there. Add that into whatever the kill-a-watt reading is for the 2 hours you have it on.

And more importantly will it help me get down to a usage that makes off grid feasible?

It is impossible to make off-grid feasible. Battery cost alone will be 60-cents per Kwh. So forget it.

Your coffee pot does not use 2 Kwh. Just like your propane you do not turn it on for two hours as you would boil all water off and scorch your pot. In reality you likely use 500 watt hour or less. To calculate or compare cost between fuel source you have to find the common denominator which in this case is BTU's which is extremely hard to determine for your propane because you cannot tell us at what rate you burn propane. Is it a simmer or a torch? You cannot answer.

However I can tell you exactly what 1 million BTU's is for both electricity and LPG based on the information you gave me.

Electricity = 293 Kwh x $0.15 per Kwh = $43.95
LPG = 11 gallons x $3 per gallon = $33

LPG cost 25% less than electricity as a heat source.

Take away here is if your electric coffee pot uses 500 watt hours cost you 7.5 cents, and if you use LPG cost 5.63 cents.

Want to make that coffee on battery power will cost you 30 cents just for the battery. Add another 10 cents for the equipment and material and you are looking at 40-cents . So rush right out and get a solar system with batteries and start saving money today.

We make coffee every morning. Our programmable unit turns on at 5 15 and shuts off after two hours. And it gets left on that way. I leave before 6 and my wife before 7. So it is on for two hours. It is a 975 watt unit. So Damn near two kwh. So I pulled it's cord and I am using my percolator.

It takes 15 minutes of propane on a burner to percolate coffee. At 3 dollars per gallon of propane.

And electric at 15 cents per kilowatt. Or 2 kwh total.
Which is cheaper on grid.

And more importantly will it help me get down to a usage that makes off grid feasable?

The coffee maker probably draws 975 watts only for the time it is actually making coffee. The rest of the time it's likely using a lot less.

This is a good place for a power meter (like a Kill-a-Watt) to figure out the actual standby usage.

I recently discovered that my coffee maker uses about 1KW when I'm brewing, and 50W in standby. It's a Bunn which keeps a reservoir of water hot all the time, which is why it's always pulling 50W. I reduced my daily power consumption by 8% (over 1 kWh/day) just by turning the darn thing completely off when I'm not making coffee.

(It makes good coffee, though.)

Try checking the actual consumption of the coffee maker - it is far less than you noted.
