Question: How To Replace Hot Water Heater Element

Can you replace a water heater element yourself?

The task of replacing a water heater element may seem difficult, but most homeowners can make this repair themselves. If your water heater is slow to heat, runs out of hot water, or doesn’t deliver hot water at all, there’s a good chance that one or both of your heating elements are not working properly.

How do I know if my hot water heater element is bad?

Make sure you test both screws on the face of the element. Touch each screw with one of the multimeter probes. Place the remaining probe against the metal base attached to the element where it enters the water heater. The element is bad and must be replaced if the needle on the face of the multimeter moves.

Are heating elements easy to replace?

An oven heating element is an essential, simple part that is easy to replace in most electric ovens and ranges. Behind the plate, two metal prongs connect to two wires inside the oven. The wires typically have female spade connectors that slide onto the element’s prongs.

Are hot water heater elements Universal?

There are three types: screw in, bolt in and clamp in. They all have different wattage ratings and can work on either 120 or 240 voltage. Check your state and local codes before starting any project.

Will a water heater work with one element?

Yes, a water heater can still run if the bottom element quits. In most water heaters, the top heating element controls the thermostat and will still work even if the bottom element fails. So provided the top heating element is working, it can still produce some hot water even if the bottom heating element fails.

Are upper and lower water heater elements the same?

Upper and lower heating elements are identical, and the temperature is regulated by the upper and lower thermostat and high limit device. Electric water heater elements can be different in size, but the most common is 12″ (300 mm).

What causes electric water heater elements to burn out?

The most common cause of burned out elements on new water heater installations or new element replacements is DRYFIRE. This happens because the installer fails to open a hot water faucet while the heater tank is filling with water and therefore purging or bleeding air from the system.

What happens when a heating element goes out in a water heater?

If you have an electric water heater, the heating elements inside the tank can break and lead to a loss of hot water. Sometimes, your water will slowly start to cool down and this could be because the element has burned out. If the second element fails, you’ll be left with only cold water.

Why is my hot water so hot all of a sudden?

If your water heater is making hot water too hot all of a sudden, it’s likely the result of the temperature setting being too high, a malfunctioning thermostat, high mineral content, or the pressure relief valve is blocked. Each of these issues can cause the water from the faucet to come out too hot.

Should you replace both water heater elements?

If your electric hot water heater is slow to heat, runs out of hot water faster than it used to, or doesn’t deliver any hot water at all, there’s a 90 percent chance that simply replacing one or both of the heating elements will solve the problem.

How much does a hot water heater element cost?

Heating Element If you have a problem with your element, it will probably cost between $200 and $300 to fix it. Most electric water heaters come with two heating elements.

Can I replace a 3500 watt element with a 4500 watt element?

It is ok to install lower watt: replace 4500 with 3500 as long as voltage is same. Lower watt means less heat, so element can last longer.

Are water heater elements brand specific?

A flange type is not as common in newer water heaters. If you can’t find one, look for an adapter kit. With this kit you can replace the old flange style with a newer screw type. In most cases you do not have to buy brand specific elements.

CAN 5500 watts replace 4500 elements?

The short answer to the question is yes, as long as you have the correct breaker and wire system set up. If the breaker is 30 amp, then yes, a 5500-watt water heater should be fine as a replacement for a 4500-watt water heater.

Which element heats up first on electric water heater?

The upper thermostat first sends electrical energy to the upper element until the water temperature in the upper third of the tank reaches the thermostat setting. Power is then transferred to the lower element until the remaining water reaches the lower thermostat setting.

Why do electric water heaters have two heating elements?

With two-element designs, one element heats the water at the top of the tank while the second element heats the water within the bottom of the tank. Electric heaters feature fewer parts than gas models, but a basic understanding of how two-element models function can reduce the time needed to diagnose a problem.

Will a bad water heater element trip a breaker?

On an electric water heater, only one heating element is on at a time. However, when a thermostat goes bad, it can create a problem where both heating elements run at the same time. This draws more electricity than the circuit can handle, causing the circuit breaker to trip.

Should both thermostats on an electric water heater be set the same?

The majority of electric water heaters have two thermostats: an upper and a lower, located under two control panels. To ensure your electric water heater works as efficiently as possible, you should set both of the thermostats at the same temperature.

How long should a hot water cylinder element last?

Modern hot water cylinders are wonderfully durable and will happily chug away for 20 years without an issue. Over time, however, they can spring a leak due to loose connections, excessive pressure, cracks in the pipes or corrosion in the tank.

How can you tell if heating element is bad?

Inspect the metal wire coil for any breaks in the wire. If the wire is solid and has no breaks in it, the heating element should be good. If the wire has a break in it, the heating element is defective.
