Does anyone know is this suitable to use for a 30amp water heater and how many timer programmes per day can you use. Is it manual clock or digital

It is fine for 30 Amos. Digital timer. I believe there are 7 on off sequences. I use it to control a spa pump and 5kw heater and it works great. Don't believe the bad reviews of the case. It is waterproof and well built. I also use the manual on off switch option, so it functions as an SSR and very nicely. On the case, to open it easily just look at where the locking tabs are and push them in slightly. I don't understand how people couldn't figure this out.

A typical domestic water heater is 4500W for each element at 240V, but only one element is allowed to come on at a time. So that's 4500/240 = 18.75 amps. Even with a 10% or 20% margin, this Aube timer - rated at 30 amps - is more than sufficient. This item allows 7 programs. So you could have a different schedule of 1-off/1-on on 7 different days, or you could have 7 identical on-off cycles for all days. One of the beauties of this unit that distinguishes it from the others (including Intermatic digital timers) is that you can install an external SPST switch (a basic light switch will work fine) which overrides the unit and puts it into manual or switches it back into automatic. So, for example, I can use the switch to put the water heater into manual mode and leave it off when I go on vacation. Then, I leave instructions for my house-sitter to just throw the switch and put it back into automatic mode on her last visit so we have hot water when we get home from the airport.

I'm using it with a 30 amp jacuzzi no problem. Clock is digital. Not too sure how many programs per day you can have... but I believe you only have about 7-10 different programs available... I'm using 5 for different days... but they could be all on the same day.

I use this timer for a hydroponics grow tank. My current settings are 1/2 an hour on and 1/2 an hour off, 24/7. The time increments will go as small as 15 minutes, so you can program it pretty creatively. It's a well made device that appears pretty robust. The only caution would be the circle of small plastic tabs that control on/off switching. They seem tough enough, but you wouldn't want to break one off. Other than that, it's a very nice timer and well worth the money.

It is like all mechanical timers... You have to set the time by rotating the dial. If there is a power outage the dial will stop rotating for the duration of the outage and automatically resume rotation when power is restored. The time will not correct itself when the power is resumed. You must manually rotate the dial again until the correct time is set. I used these for heat tape switches so I didn't break the bank with my power bill and have to remember to reset the time after a power outage, otherwise the heat tape will come on at the wrong time.

This one is programmed each day. It is NOT a weekday / weekend program. I'm VERY happy with it, and my electrician installed it just about one year ago (Feb or March 2014).

This is perfect for something as demanding as a high current bathroom heater. Most light switches and timers are rated for 15 or 20 amps, which can accommodate 1800 or 2400 watts respectively. Try to imagine 18 or 24 100 watt light bulbs (1800 or 2400 watt) being turned on at once. No big deal?? Not unless you decided to save a couple of bucks and buy the lower rated switch/timer (15 amps) and turn on the 24 light bulbs. It will work just fine...for a very short time. Heaters generally require a larger number of watts (wattage), anywhere from 800 to1600 watts or so, allow for spikes (headroom) and buy the heavier switch/timer...you then won't need to revisit this for many years.

If your water heater plugs into an outlet, a regular timer will work fine. Most water heaters, however, are 220 volt lines on a dedicated circuit, thus you need something more like the WH21. Here's a good reference for you: http://michaelbluejay.com/electricity/waterheatertimer.html

Hi Robert I am also looking for the same thing you need. Please let me know if you found a timer you could recommend to me. Thank You Please email me at yourserviceguys@gmail.com

There is an adjustable thermostat. It's a great machine and pretty much foolproof and NESCO is a reliable and helpful company. You won't need a timer for the drier, but if you wanted to you could just plug it in to one of those outlet timers you can buy at any hardware store.

This timer is a simple set the time to water. Mine has worked very well and does shut off as expected. This one does not have a multiple program capability.

Any basic timer should work well // purchased here on amazon or local hardware store the digital May have more options than the mechanical

you connect the 2 timer in series or parallel? (if series the timer front and back in the circuit may cause the on off problem) You are saying the timer can not switch to auto and the manual function also not working? Had you check your supply at the timer terminal is it connected correctly? The timer activation time "on" and "off" is set correctly? Do you set it to be turn on and off on specify day or everyday (need set and select day/days)

You can go on taymac website and see all products and sizes, not sure what timer your trying to use

Yes.The timer allows you to set up to 7 different programs, you select which day(s) of the week will be included in each program.I have two programs running: 1) Monday to Friday OFF from noon to 6PM (side result: heater is ON from Friday 6PM to Monday noon). 2) Every day ON at 5AM, and every day OFF at 11PM, this means that the heater is off every night from 11PM to 5AM.

Don't use a timer. Your plants will dry out and die. The pump that comes with it is a lot larger that i would have expected. Placed the unit in a 77 degree room. The water temp rose to between 78-80 the next day, acceptable. If you are worried about the water temp, you can buy a smaller pump, only about $15, and that should keep the water a little cooler. Also, keep the water level just below the jets, that will elp keep the temp down. Good product.

There are two on the front of the heater, one for minimum heat, one for medium heat and then if both are switched on together it would be for maximum heat. There is also a button on the front that if depressed it is for "comfort temp". There is also a temp dial on the front. I can't say if that would work with an external timer, you would just want to ensure that the right combination of switches & buttons and the temp dial were all where it is comfortable for you so that when the timer turns it on it is set at the right temp.

it is programmable to be on and off at a specific time during the day. If u only want to use it in the morning you can set the specific time on period. There is a heating element that stays hot waiting to heat the water. I have always had to wait for the water to heat prior to making a cup. So, I do not believe there is a Resevoir of stored hot water, surely it doesn't heat the attached large red our of water.

The wattage rating is 1800w. Having said that, the timer is overkill for what you need. You really need a basic 24 hour timer without the astronomic feature. Also, I would go mechanical rather than electronic for that use.
