Check The Heater Element With Your Multimeter

Generally speaking, the functioning of a heating element is governed by the resistance present in the circuit, which is measured in ohms . Adjust the ohms setting on your multimeter to the lowest possible value. Touch the center of one of the heating element screws with the red probe, and the center of the other screw with the black probe. When measuring resistance, it makes no difference which probe is in contact with which screw. In order to determine whether or not the heating element is functioning properly, your multimeter should read anywhere between 10 and 30.

If your water heater has two heating elements, repeat this procedure on the other heating element.

Size And First Hour Rating

How To Tell If Your Electric Hot Water Heater Is Bad?

The heat pump water heaters size and its first hour rating can make or break its usefulness. The first hour rating is the number of gallons of hot water the heater can supply per hour . Look for an EnergyGuide label on any new heat pump water heaters to determine the first hour rating and try to find the model that best matches your peak hour demand. The peak hour demand is the highest-use one-hour period in your home.

You can estimate peak hour demand by calculating the busiest hour of water use in your home and adding up the average use for each activity in gallons. You can find average gallon use for each activity online, but for reference: showers use around 20 gallons, shaving can use around two gallons, a dishwasher can use seven and a half gallons and a washing machine can use between 15 and 25 gallons depending on the model.

Electric Water Heater Thermostat Location Adjustment Settings & Test Or Replacement Procedure

Electric water heaters usually have two thermostats, and to heating elements: an upper thermostat located behind a cover high on the heater tank, and a lower thermostat located behind a panel low on the water heater tank .

The two access panels permit inspection, adjustment of the thermostat, access to an internal reset switch , and access to electrical wiring as well as access to the actual heater elements should one or both of them need to be tested and/or replaced.

Signs That Your Water Heaters Thermostat Might Be Faulty

Most electric water heaters have two thermostats: an upper one and a lower one. The upper thermostat is the primary thermostat and is attached to the high limit switch, which keeps your water from getting dangerously hot. Depending on which thermostat is malfunctioning, you may see different symptoms:

  • No hot water This most likely indicates a problem with the upper thermostat.
  • Not enough hot water This most likely indicates a problem with the upper thermostat.
  • Slow hot water recovery This is another problem that can occur when the lower thermostat is malfunctioning.
  • Water is too hot Overly hot water can occur if either thermostat is set too high or isnt calibrated correctly.
  • High limit switch keeps tripping If the red reset button on your water heater keeps popping out and needing to be reset, your upper thermostat could be malfunctioning. This would allow your water heater to keep heating the water to dangerous levels, which will trip your high limit switch.

If you notice any of these signs and you happen to have a multimeter, test your water heaters thermostats to see if theyre the problem.

What Else Can Cause Bad Or Low Performing Heating Elements

Dry-fired elements

Every time you resume the power after the service, ensure that your storage tank is full of water otherwise, heating elements can be exposed to air and lead to dry fire and damage.

Limescale build-up

Due to hard water, heating elements can be subjected to sediment build-up, resulting in lower efficiency or even breaking when heavily covered in limescale and exposed to high temperatures.

Voltage spikes, water exposure and mechanical stress

Heating elements can also break when a voltage surge occurs due to weather, such as lightning or even a power surge.

Water leaking is not good, and if heating elements get in touch with water, they can break.

Vibration and mechanical stress are also not good. Check your heating elements for any signs of deformation. Any breakage on the inner filament will show no continuity when you test the element. In such a case, replace an element.

    How Do I Determine If A Water Heater Is Gas Or Electric

    Sunday, September 23, 2018

    Look at the top of a tank-type water heater. If there is a flue rising out of the center of the top of the water heater, then it is a gas water heater. Also, an older gas water heater has an access panel to the burner at the bottom of the tank to light the pilot light, and all have a dial to adjust the temperature in the same area.

    An electric water heater does not have a flue and, instead, has electric cable or conduit connected to ittypically at the top surface. The only exception to this way of determining what fuel source a water heater uses is a tankless gas water heater installed at an exterior wall. It will have louvers around the top area to exhaust combustion gases instead of a flue, whereas an electric tankless water heater will not have the louvered ventsalthough we have never seen an on-demand electric water heater installed at an exposed exterior location.

    Whats Inside A Water Heater And How It Works

    The vast majority of domestic electric water heaters feature two heating elements: one near the top of the tank and another towards the bottom of the tank. After entering the top, power travels to the high-temperature cutoff switch, and then to the thermostats and elements on each side of the unit. The temperature of the top and bottom components is regulated by two different thermostats. When the water at the top of the tank becomes too hot, the top element goes off and the bottom element takes over to heat the water.

When your water heater, on the other hand, generates lukewarm water that is incapable of serving the intended function, it may be really annoying. While a variety of factors can influence the efficiency with which your water heater operates, a malfunctioning element is one of the most common reasons of water heater failure.

    As a result, it is necessary to understand how to test and replace a water heater element. With the help of a digital multimeter, we will demonstrate step-by-step how to test water elements without the need for any prior experience in electrical work in this article.

    Check The Water Heaters Status Indicator If Any

    Water Heater Not Heating? Thermostat Testing

    One of the most straightforward ways to tell if water heater is working or not is by looking at its status indicator. Most water heaters have an LED light on the control panel, indicating their current working status.

    Many water heaters have a lit green LED light to show the appliance is turned on. If the LED light is red, there might be a problem. You can say the water heater is turned off if the LED light is not lit.

    Unfortunately, some water heaters do not have a status indicator. That is why I recommend checking the user manual to determine if your water heater has this feature.

    Accessing The Electrical Wiring On The Water Heater

    Behind each electric water heater panel you will see electrical wiring, a thermostat with a pointer and temperature setting numbers.

    Watch out: Turn off electrical power to the water heater before opening the water heater access panels.

    Otherwise you could be killed by electrical shock.

    Smart repair people and owners use a neon tester or multimeter to absolutely confirm that electrical power has been turned off before ever touching electrical components.

    We removed the upper panel metal cover , lifted off the styrofoam insulating cover, and revealed the water heater control in our photo at left.

    If you break or lose the plastic cover that protects the water heater thermostat and heating element electrical connections, a replacement cover is provided with most water heater element replacement kits.

    Also located behind each panel is the actual upper or lower heating element. Our photo is the same location as we showed above, but we removed a plastic safety cover to show the electrical connections and other controls available here.

  • From the top of the control you can see
  • Electrical wires bringing power to the heating element
  • A red “reset switch” for the electric water heating element control.
  • Electrical wires taking electrical power out of the thermostat control and into the electrical heating element itself.
  • The electric water heater temperature setting dial.
  • The electrical wires connected to the head of the water heater heating element.
