The WH40 Mechanical Water Heater Time Switch regulates electric water heaters. Utilities in many areas of the country offer two electric rates for residential or commercial customers. One rate has the regular daytime rate, the other is the 'off-peak' rate. This 'off-peak' rate provides customers with lower priced electricity during the nighttime and weekend periods. This time switch allows the customer to shift electricity use into the 'off-peak' time periods in an attempt to save utility costs.

Will it work with a neutral wire? I wired it 240V with two hot wires and a ground, but when I turned the switch to off, the clock turned off. So it was fundamentally a 240V switch. But I'm wondering if the clock needs a neutral wire to work when off
Asked by: Killa
Yes. The clock needs a neutral wire for it to work when the power output is turned off.

Does using a timer really safe you any money in power cost?

My water heater is 50' from sink. Have to run water 2 min before hotwater gets to sink. When i had another house with gas water heater I used circulator pump so I got hot water to the sink quickly. With electric water heater would add to mich to electric bill. To solve this problem I installed a 2 gallon water heater at the sink connected in line with the hot water supply so that I have hot water instantly and at the same time if I used enough hot water the under sink heater gets fed hot water from main heater. So I'm thinking if I had a timer turn off the main water heater during the day and just use the little water heater under the sink that I wouldn't be bringing on the main water heater and that should save money and then let the main water heater turn on at 5 PM till midnight for dishwasher use and showers and wash. Your thoughts please
Asked by: AL
Yes it does , kind of.. these timers are what I believe being made over seas and the quality is crap.. Better to just install a switch and control the WH manually ... want to save - build a radiant / solar heater and cut the electric cost by 90%

40-Amp 240-Volt Electric Water Heater Time Switch is rated 4.4 out of 5 by 90.

I am a licensed electrician for over 30 yrs, I have used these in the past and alls been good but the 2 last ones I installed didnt last 2 yrs. So I believe they are being outsourced from a communist country . What saving you have is all gone because of the need for a replacement timer ... Just purchase a manual disconnect and get in a habit of turning it on and off yourself.

I have used one at another home for eight years with no problems. The only criticism I have is the timer is noisy!!! The old one was noisy and the new one I bought last month month is just as noisy. You can hear the timer running. The second thing is the ground wire connection requires the wire to be bent around the screw. On the other terminal connections you don't have to bend the wire. You can leave the wire straight and insert it in the connection and tighten the screw. Thanks

One was installed in a guest house and never used, the timer mechanism stopped working when I needed to use it. The second unit was used for a few years and it also had the timer clock mechanism go bad....so maybe a different brand would be advised.

The only issue with this timer is the On and Off clips become loose and can damage the tines if they jam the timer. They need to be checked regularly, and it is not something people think of until there is a problem and the unit needs to be replaced.

The ground mounting hole is a joke! try attaching two ten gauge wires to that tiny screw was impossible. I had to enlarge hole to properly attach ground wires. Once that was done everything else was a breeze to install wires. Its very quiet running unit. And it is working fine.
