Record Low Electric Bill for September:

[Scanner]

$42.00

I was aghast.

I even ran a window air unit a few times during the evenings.

Makes me doubt the wisdom of swithcing my electric hot water heater on a timer to tankless natural gas hot water. I suppose no energy to heat water that's not in use is better than even cheap electric to heat hot water 12 hours/day (12 hours off).

Or, consider a passive solar heating system for hot water; would that work where you live? You're probably just fine with the set up you have now.

on demand water heater is almost always cheaper. Once my tank craps out, that's what I will be installing.

I had a $45 bill (billed every 2 months) for August and September with 0kw usage. Come to find out, as I questioned it (never do that!), that our meter stopped working. Power company came out and replaced it. They missed out on peak season when we were cranking the A/C and running a dehumidifier 24/7.

I should have never called! Looks like our reassessment of our budget bill will be artificially low for Nov 2011 - Nov 2012.

I too wonder if and how much I would save a month if I switched from a 40gal natural gas water heater to a natural gas on demand unit.

The on-demand units are fantastic. I have one in my apartment here in Japan, and it works great. Turn it on, hot water in less than a minute, and I've never had it run out. And even with the high cost of living and abysmal Yen exchange rate, my gas bill is still below $30/mo (electricity normally $50-$60/mo, though I've had it get up to $180 -- oops ).

One big factor I think alot of electric utilities have is that many use "tiers" of energy usage... Say you get charged $.10/kWh from 0-20 kWh, $.20/kWh from 20-50kWh, and $.30/kWh from 50-100kWh (totally arbitrary numbers, example only). I've discovered if you can keep your average power usage even moderately low, the total cost drops off significantly.
