Any recommendations? I am a renter so it can't be permanent. Where do I get them? What hours to I have it shut off? Like 3 AM-5 AM and during the day when at work?

Our local electric company installs them for free. I would check with your local company to see if they have a program or will reimburse some of the cost.
We just had a smart system installed on our home that lets you set and manage exactly how you want the programs to run. You can run multiple schemes for weekday, weekend, vacation, etc. It also allows remote changes via the web, in case your kids are home you can override and turn the heat up on em, jk.
On the water heater, basically the power gets cut off and on. Ours runs from 5am-7am and 6:30pm-8:30pm with it being off the rest of the time.

Noticeable change in your bill?

Is it a modern hot water heater? Ours will go 8+ hours without cycling after the morning use of hot water. Modern hot water heaters have little standby loss so shutting it off two hours is useless. I think you would be saving pocket change in most cases.

Yes, the way our house monitoring system works allows you to see detailed usage of the controlled systems and other usage in the home. It's displayed in graph, with 7day summary, day detail, and 24hr detail. Having the detailed data really lets you dial in your usage and pinpoint potential waste sources.

Overall our bill was pretty low to begin with especially for our area. We are typically sub $100 and maybe 1 or 2 months at 100-130. We are good at saving energy and our home has some added energy saving features. Percentage wise, the drop compared to last years usage is in the 15-20% range, but there are so many variables this could be attributed to other factors.

If the system is free from your energy company, why not put it in just to have the knowledge.

I think the only systems they have currently only work on the electric appliances. To get the most savings you have to only have it come on once or twice a day.

Called the electric company and they have a similar program. Free install but basically if I use electricity during peak hours i get charged at a higher rate and if i use it at non peak hours I get a lower rate than normal. The guy said the water heater uses so little electricity it's probably not worth my while so it looks like I will just leave it be!

Ya, there is always a reason they provide it free. Here its you allowing them to control your unit 1-2? remotely during peak hours for the next yr. You can always override the setting locally, so it's not that bad. Anytime we've been home during a peak hr override, we usually just manually change back down to our setting.

Is this your savings on just the water heater or on your whole house? It seems like you have more than just water heater control.

OP, you might benefit by turning down your hot water heater or insulating it.

We have a whole house monitoring system, I think these is a typical system utilities use. The biggest energy use in a home comes from the HVAC unit, so I'm sure most the savings can be attributed to the custom schemes for the AC.

unless its 30 years old they have a lot of insulation on them anyways standby losses are very little in a hot water tank. You could turn it down but the lower you go the more risk of disease in the tank.

Iagree

If you can touch your water heater and it's not hot, then it doesn't need more insulation. You'd be better off insulating the hot water pipes, if you can.

Ive insulated my pipes and I actually noticed a difference in temperature in the water upstairs. As to what the savings are probably not much but it only costs $5-$10 to do.

Especially if your water heater is in a garage, or other non-temperature controlled area.
