It is a device that opens on its own if a certain condition is reached. Let's say you are designing a water heater. You know if everything goes wrong the unit could reach 210 degrees F, or to have 150psi pressure inside it. You also know if either of those things happen the water heater could explode...so you put a safety valve on it that opens if either condition is reached.
120 degrees
The purpose of a safety device is to reduce the danger of injury.
Force and motion might be associated with a safety device.
It is a water heater, not a hot water heater. There would be little point in using a hot water heater. I assume that is your point.
With out a better description of what the power saving device is and how it is connected into the water heater's circuit, an answer can not be forthcoming. If the device is connected in series with the "hot" line of the heater and it opens the lines up then of course the hot water tank will not work. If you go to the discussion page and leave more information, an answer might possibly be found to your question.
Only an expert plumber should install a new hot water heater. An incorrectly installed water heater not only imperils you but your family, to protect your house, we can install a Wags valve that will lock the water and gas before it has an opportunity to harm your property. This modest device can help save you hundreds and even thousands of dollars down the line; it infringes state and local codes. We are very familiar with all city codes and safety requests governing hot water heater installation, and we will see to it that your water heater is safely and duly installed.

In a hot water heater, a thermostat regulates the heat
Hot water in homes is produced by a device called a water heater. A water heater can be compared to a pot of boiling water. The enclosure keeps water hot throughout the day so that when the faucet is turned on, there will be an immediate flow of hot water. The people who have hot water have invested in a water heater.

For safety, it should be kept below 120 degrees F.
is it a diverter valve or immersion heater then? only need a simple answer haha

Yes. A solar heater would do that, if there's sun light.
