Which is better? Got the Bradford White 40 gallon electric water heater installed and it is running great. Only problem is that it cycles on and off once about every 30 to 60 minutes. Runs for about 5 or 6 minutes and shuts down. Must be doing that to keep the water up to temperature. Well, we only need the hot water to wash dished in the dishwasher and to take bathes . The dishwasher has a built in 4 hour setting on it , that allows it to start up 4 hours after you press start. The only other use for the hot water ,is for baths. Figure that if the timer was set up to run the water heater from say, Midnight, to about 3 AM. There would definitely be enough hot water for a quick bath or shower in the day time.
Eventually, we plan to go on the cheaper Day Night electric rate . The night rate is 2/3's the cost of the Day rate. Night rate being 11:30 PM to about 7 AM.
So, that brings me to these questions:
1. Which of those timers is better ?
2. When you installed them, did you notice a savings in your electric bill , once they were in use?
3 On the electronic timers, how long does the battery usually last ?
