The DOD can do anything with all the blank checks they have. Solar panels ain't cheap, for a reason.I installed a timer on my daughters hot water heater, she wasn't sure it would help but I talked her into it. She loves it now, saves quite a bit money. If everyone with electic hot water heaters put timers on them Dominion would have a cow. Its easy to do, don't have to call any pricey electrician.

Actually, it's a reasonable estimate.

The analysis is left as an exercise.

Could you please elaborate? What does the timer do?

When will the project actually pay for itself? And how soon will the solar panels and related equipment have to be replaced and, again at what cost?

There are many who doubt the effectiveness of timers but having seen the evidence myself in 3 different households they can eat cake. The idea is simple, most users with electric heaters don't use hot water for most of the day, that means the heater is keeping 40 to 50 gallons of water at 120 degrees or better for multiple hours on end. Dominion loves you. The timer is merely a circuit interrupter, you decide when you need the hot water in the morning or evening. Just set it for app. 15 or 30 min. prior to use. Now here's the standard argument. The heater has to work harder to bring all that water back up to usable temperature. False, that assumes that as soon as the circuit cuts off, those 40 or 50 gallons automatically return to room temperature. Wrong, if one uses a heater blanket along with a timer, or even not, it takes hours for all that water to cool down. It works. Sold at Lowes for about 50 bucks, those same 50 bucks can be saved in your electric bill in the first 2 months, or less.

Sort of. The rationale is correct, but the numbers are way off. Letting your water heater cool during the day will save wasted heat, but no where near $25/month. That would be the total water heating bill for a reasonably conserving household.

Waste heat is a small percentage (~10%) of your water heater use; the best you could do with all the insulation in the world (or a magic timer) is a few bucks a month.

Dominion, however,_will_ pay you money to put a timer on your water heater, not to reduce consumption, but to reduce peak demand. Of course, you can't use your heater during peak times, then.

The easiest way to conserve hot water is to put in low-flow shower heads and wash your clothes on cold. The City has a _free_ water conservation kit that you can pick up at City Hall, and a $100 incentive for installing a low-flow toilet.

Your water heater is resoncible for 40% of the average electric bill. Depending on where you live your bill can vary substantially. Those that have installed timers live in the county and the savings of a timer have been well above 25 bucks a month. Always a doubting Thomas. Low flow devices are nice put your still left with heating 40 to 50 gallons of water all day long, a complete waste of energy and money.

They are _not_ saving $25/month by reducing heat loss from their water heater. It's just not feasible.

Something else is going on, such as switching to a time-of-use rate, getting a peak demand rebate, changing water use habits or equipment, or not calculating the savings correctly.

For those who want to reduce their bills, reducing consumption is the first thing to attack. Then insulate your tank._Then_ look into rate switching. A family of four need not spend more than $20-30/month on water heating.

Facts is facts, until you try it yourself you just don't know, I know cause I can see. You can argue all you wish but there it is, unless you work for or invest in an electric company.

Or understand basic physics, and spend a fair portion of your career evaluating energy conservation projects.

The $100 dollar incentive is ONLY if you are using the city's water; if you are on a well, your out of luck. I installed low flow toilets in my house because I wanted to save water period and reduce my bill. It does really reduce it. The toilet pays for itself in about a year and a half.

You're right: free's daughter must have been using (wasting) a heck of a lot of hot water, or else got conservative in her electricity use overall. Hah, imagine free or her daughter being conservative about anything!

Fine, your electric companies love you, keep on using up the juice and throwing away your bucks. The odd part is how do you argue a point having never seen the evidence yourself. If timers weren't tried and true, why are they on the shelf at Lowes for sale? Naysayers always spout what they believe to be true right up until reality hits then in the face, then they say I'll be darned.

I tried em. Made no difference I could discern. They are on the shelf at Lowe's because people will buy them, especially ones influenced by their mother.

So your cheap shot at my dear departed mother gives you credibility to this issue. Thats OK, I'll match my bank account against yours anyday.
