I just need to turn the water heater on for a couple of hours on Tues and Thurs, will this timer do that?

It has the option to program your schedule during the whole week. For instance, to maintain hot water in my houses the timer turns on the water heater at 7 am, 3pm and 8pm every day. I hope the information is useful.

Yes there is an on/off button for use at any time you want. Remember, it takes a few minutes to warm the tank, so turn it on before you use the hot water.
906961
yes, but for that I would strongly recommend a mechanical timer that are used for pool filters. Much, much more reliable. This unit will, I repeat WILL fail within 18 months. I went through 2 . . . the first failed in 6 months, the second 13 months. Cheers!

Yes, Its fully programmable for 7 days ... You can tailor each day to do what you want.

Yes, you may. Just move your settings from timer to "on" position. Remenber this is a small pump, you can't have hot water right away.

Hi Bo, I have used one of these WH21 for the last 25 years. This version of timer is only for controlling on and off in a 24 hour period. It will not help you with the issue that you described. Thanks,Ed

If you leave the light on then the power is going thru the unit and the heater coils will heat the water up to temp in say 10 mins or so and you could then "take your shower" ........................... if you forget to go shut it off it will continue to keep the water at the set temp and cost a lot to maintain that temp.Really if you take a shower everday at say 6am then just put the timers on to have the heater come on for 30 mins starting at 5:30am and when you hop in it will be all hot for you and you don't have to mess with it again, it will shut off at 6am and you will have hot water most of the day ...................... the main reason for buying one of these is so you don't have to mess with it???

No timer... It controls water temperature by turning on when the temperature of the water flowing through rises about your desired setting

This unit does not do that, but you can purchase a timer in any hardware store, home improvement store or probably here on Amazon. They are fairly inexpensive. Just plug your heater into the timer and the timer into the electrical outlet, and you can control both when it turns on and when it turns off.

Yes! I would use the remote to help turn on & off as well if you want it lot more than 5 hours for the timer.

The timer is a count down timer. It does not have a real time clock. To use it, you need to tun the heater on and then set it.

Rian Ketter is correct. The timer is optional. I have used the timer only because I occasionally forgot to turn off the heater before I went upstairs to go to bed--and was way annoyed with myself when I came down the next morning and the thing was still running. Waste of electricity!

Yes it will. The individual circuits allow you to adjust which circuits you are using that would max out the input. I have mine set up so that it will only heat water if I turn off a few circuits that would run normal stuff while I turn on the water heater. Once I have hot water I shut down that circuit and light up my normal circuits again.

Joseph... the answer is NO! The timer can be set to start and stop "once" OR "twice" a day. The amount of time you want the water to run during the ONE or TWO sessions can be broke down to hours and minutes.
1962448
Yes. I generally set a timer for about 17 minutes then turn it off myself, just because I don't want to forget and it doesn't have any sort of beeper. Once the water boils out it turns itself off.

Yes, the timer is an old-fashioned mechanical type, for 24hr period, within which you can set any on/off intervals of 15-min increments. I have my pump running from 6:30 am to 10 am and from 5 pm to 11 pm.

Then the water heater doesn't automatically come on. But you can turn it on manually at any time.

I'm not sure, as we do not use ours on a timer. Sorry if this isn't helpful.

This timer needs power to operate when the power is off it does not continue to keep time. The current time will need to be adjusted once the power comes back on.

Not sure. I haven't used that feature. But I'm guessing it is used to set when the heater need to turn off not on. I'll let you know on my next post
