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.

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
For us, it is not an issue of saving money. We are off-grid, and we only want the water heater to run during peak solar output at mid afternoon. This lets us control when the water heater turns on, if needed.

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.
