Preparing to Change Your Water Heater's Heating Element

Heating elements are also chosen immersion heaters, because they are fully immersed within the water of the tank. It'south important to note, that heating elements are only used on electric water heaters. Gas water heaters heat the water using an entirely different method.

Heating Element Style

At that place are 2 dissimilar styles of heating elements:

Spiral-in: This is the blazon we will be roofing because they are the well-nigh common heating elements. They typically are used on all newer water heaters, and the chemical element is screwed into place.

Commodities-in: There are several different styles of commodities-in elements, if you have an older h2o heater it'south possible that this type is installed. The element is secured into place by 4 bolts. Universal adapter kit are available if you desire to accommodate a screw-in element into a bolt-in element.

Heating Element Location

Electric water heaters have two heating elements. At that place's an upper element, which is located behind the upper access panel, and a lower chemical element. The lower element is typically the one that needs to be replaced.

Equally the sediment within your tank accumulates, information technology will settle at the bottom where your lower chemical element is located. The sediment surrounds the element and causes it to lose it's effectiveness. Somewhen, it will either break or completely brusk out.

Purchasing New Heating Elements

When selecting new heating elements, information technology's recommended to purchase ones with the aforementioned voltage, wattage, and fashion (spiral-in or bolt-in) equally the chemical element you are replacing.

The voltage of the new element should always match the erstwhile element. Nevertheless, you lot could use lower wattage to extend the life of the element. Go along in heed, the element will also generate less heat. Never buy more wattage than your previous chemical element.

The voltage and wattage is normally stamped onto the element, or it can be constitute on the water heater'southward nameplate. If you can't notice it, yous can always do a simple online search using your water heater's model number (plant on the name plate).

However, if your heater is newer and y'all live in an area with hard water, you should consider the other more expensive options. Let'due south take a closer look at each:

Loftier Watt Density Heating Element

High Watt Density Elements are the most common h2o heater elements and can be used in all replacement scenarios, assuming the wattage and voltage match. In most cases, a loftier watt density element volition be the same type that came with your original water heater.

High watt density elements are decumbent to corrosive build-up and have a shorter life span. Y'all can expect these elements to be the least expensive of the three types.

LASCO Loftier Watt Density Chemical element

The LASCO 40-1015 High Watt Density 1500-Watt, 120-Volt Electric H2o Heater Element has a screw-in base with i-1/4 inch thread.

Low Watt Density Heating Chemical element

Low watt density elements are well suited for areas with hard h2o. Many are made with a fold-back design to permit for more heating infinite. Even though these are a lower watt density, in that location isn't a loss in efficiency. This helps them reduce the lime scale build-upwardly that's mutual in areas with hard h2o.

Provided y'all have the same wattage and voltage, you can use a depression watt density element to replace a high watt density element. In virtually cases, these elements will be more expensive than the high watt density elements discussed above.

DERNORD Low Watt Density Element

The DERNORD Foldback is a low watt density heating element. It is bachelor in 4500-watts and 5500-watts.

Lime Life Chemical element

Lime life elements are normally the about expensive element, however, one time installed, they often volition out live the life of the water heater itself.

DERNORD Ultra Low Watt Density Element

The DERNORD Ripple is an ultra depression watt density heating element. Information technology is bachelor in 4500-watts, 5500-watts, and 6500-watts, and resists limescale deposits.

Necessary Supplies

In society to change an element you'll demand the following:

• Garden hose

• Turn OFF the h2o supply to the water heater by closing the common cold water inlet valve (most ordinarily located above the water heater).
• Release the hot water pressure level by allowing air into the tank. To do this, open up a nearby faucet. Merely open up the hot water tap, not the cold. Be certain to leave the tap open.

Step iv: Remove the Access Panel Cover

• Use a spiral driver to remove the cover of the access panel. The upper console houses the upper water heater element. The lower console houses the lower element.
• At that place'south unremarkably insulation betwixt the panel door and the thermostat. Set the insulation aside in a dry identify.
• The thermostat should accept a plastic embrace. Gently remove the cover.
• Check the wires with a volt meter to ensure that there is no power.
• Audit the wiring. Has any of the wires been damaged? Are there any melted parts? Wiring can exist damaged if sediment has acquired an element to overheat. Whatever damaged wiring must exist repaired.
• Loosen the screws and disconnect the two element wires from the heating element.

Step v: Remove the Heating Chemical element

• Apply a heating chemical element wrench to remove the element. It's designed specifically to remove electric water heater elements, and has a wide mouth that fits over the exposed part of the element.
• While the tank is notwithstanding full of h2o, slightly loosen the chemical element in a counter-clockwise movement. The h2o's weight will help go on the tank in place.

• Check the newly installed element for leakage. If leakage is present, plow off the cold water supply and tighten the element. Information technology may be necessary to remove the element and reposition the "O" ring.
• As the tank fills, the water will brainstorm to sputter from the open faucet tap (left open in Step 3). The water is pushing the air out of the line. Once there's a steady flow of water, the faucet tin be turned off.
• Replace the plastic thermostat comprehend, insulation and access panel cover.
• Once the tank has filled with water, you can turn the ability back ON to the h2o heater by flipping the excursion breaker ON.
• Since there will most probable exist air in the hot water lines, it's not uncommon for the hot h2o faucets throughout the house to sputter. This will go abroad in a short period of fourth dimension. Yet, if yous prefer, you can open each faucet until y'all have a steady flow of water.
