Purpose of the Reset Button

Almost everything you see on a hot water heater has a purpose. Similarly, the reset button on a water heater also has a function. It stops the flow of electricity/power that the heater needs to perform all the functions. This is a safety feature in almost all heating units. This can stop the flow when the thermostat is not working. A power surge can also be another reason. The reset button ensures the water doesn’t get too hot in the heater. It has to maintain a balance.

How Do Hot Water Heaters Work?

The water fills in from the bottom of the water heater. It is the job of the lower thermostat to heat the water initially. But when the water travels up the tank, the upper thermostat or the heating element heats the water. After the tank is filled, the water settles down and gets cool. Then the thermostat starts heating again but when the water is needed. The upper thermostat has a temperature limit. When the water reaches that limit, the thermostat shuts off automatically.

Lower Heating Element/Thermostat

The lower heating element or the thermostat heats the water first. But if it is not working, the water travels up the tank cold. It remains cold throughout, and when you open a tap or a kitchen faucet, you will get cold water. This is because the water did not heat up at the bottom of the tank. So it settles down the same way and comes out cold.

Upper Heating Element/Thermostat

If the upper heating limit or the thermostat stops working, the water heater will have warm water in the beginning. However, it will turn cool once you start using the water. This is because the water has no heating element when it settles down in the tank. It only gets heated initially by the lower thermostat before it travels upward in the water tank.

Maintenance of a Hot Water Heater

All our appliances in the house need maintenance. Similarly, a hot water heater also needs some maintenance to work correctly. Initially, it might be challenging to maintain a new water heater, but the following ideas will make your life easy. Follow these small instructions, and the water heater will last for a decade easily.

  • The first and the easiest way is to flush the hot water heater. Open the valves of the heater and let the water come out. When the tank is empty, clean the sediments from the bottom. Put some water to clean thoroughly. Repeat until you think the tank is clean and then fill it up.
  • Whether the heater is electric or gas-powered, reset and adjust the temperature. A temperature dial is present at the side of the water heater. You need to unscrew the cover first and adjust the dial. The ideal temperature is 120 degrees F. You can use a flat-head screwdriver for removing the cover. Keeping the temperature at 120 degrees F can also save the energy cost up to almost 5%.
  • Most of the water heaters have a vacation mode. Set the water heater to vacation mode when you plan to travel to another country or city. This can save a lot of energy as the heater runs at lower temperatures than usual. The vacation mode is usually the temperature below 50 degrees F and also impacts the environment.
  • You can check the temperature and pressure release valve or TPR. This can be left open under the bucket. Let the water drain out and turn it off after some time. If the water still flows in the bucket, you should replace the old TPR valve with the new one. This is the safety mechanism of the water heater.
  • An anode rod is present in a water heater. This helps in protecting the water tank from rust. If you notice that the anode rod is rusting, replace it with a new one. This will make the heater last long. The rusted rod can leave a rusty smell and gel-like substance in the water. Even if the rod does not deteriorate with time, it is recommended to change it every five years.
