Programmable electric water heater timer

Hello,

Anybody have any experience or opinions on using programmable timers/thermostats on electric wh. Wifi or non-wifi models?

I didn’t know they existed. My friend just moved into a new home and the builder says his traditional tank type gas water heater has “on-demand functionality”. That got me thinking. Not sure what on-demand functionality means for a gwh.

With time of use electricity prices, I feel like this might be a good option. Our highest prices at peak times are double the non-peak times. In winter, peak time is 7am-11am and 5-7pm. We wouldn’t probably need a lot of hot water during those times, even though we work from home.

Would the savings be lost as the heater turns on again at 11am and 7pm and tries to bring the temp up?

Looks like they want to be the “nest” of water heaters.

Opinions?

 

You can use any HD 240v timer to do that. We used to install them all the time when they had dual rates. No more dual rates anywhere in my area. You'll have plenty of hot water.
