Preparing to Change Your Water Heater's Heating Element

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

Heating Element Mode

In that location are 2 dissimilar styles of heating elements:

Screw-in: This is the type we volition exist covering because they are the most common heating elements. They typically are used on all newer water heaters, and the element is screwed into place.

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

Heating Element Location

Electrical water heaters have 2 heating elements. There'south an upper element, which is located behind the upper access panel, and a lower element. The lower chemical element is typically the one that needs to be replaced.

As the sediment within your tank accumulates, it volition settle at the bottom where your lower element is located. The sediment surrounds the element and causes it to lose it's effectiveness. Eventually, it will either break or completely short out.

Purchasing New Heating Elements

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

The voltage of the new element should always match the old chemical element. However, you could use lower wattage to extend the life of the element. Go on in mind, the element will also generate less heat. Never purchase more wattage than your previous element.

The voltage and wattage is usually stamped onto the element, or it tin be found on the water heater's nameplate. If you tin't find it, you lot tin can always do a uncomplicated online search using your water heater's model number (establish on the name plate). If all else fails, or you feel more comfortable, you lot can remove the element and accept information technology to your local hardware store.

Types of Water Heater Elements

There are 3 types of water heater elements. If your water heater is nearing the end of it's service life, yous may want to install the least expensive, high watt density element.

Notwithstanding, if your heater is newer and you live in an area with difficult water, you should consider the other more expensive options. Permit's take a closer look at each:

High Watt Density Heating Chemical element

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

High watt density elements are prone to corrosive build-upward and take a shorter life span. You tin expect these elements to be the least expensive of the iii types.

LASCO High Watt Density Element

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

Low Watt Density Heating Element

Depression watt density elements are well suited for areas with difficult water. Many are made with a fold-dorsum design to allow for more than heating space. 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-up that's common in areas with difficult water.

Provided you accept the same wattage and voltage, you tin employ a depression watt density element to replace a high watt density element. In virtually cases, these elements will be more expensive than the loftier watt density elements discussed in a higher place.

DERNORD Depression Watt Density Element

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

Lime Life Element

These premium elements carry a express v-year warranty. Lime life elements are ultra low watt density and have a loftier quality nickel and stainless steel surface that discourages the build-upwardly of lime scale.

These elements are an first-class pick if yous live in an area where you experience intermittent water supply levels, equally they resist dry firing. Lime life elements are usually the about expensive element, however, once 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 low watt density heating element. It is available in 4500-watts, 5500-watts, and 6500-watts, and resists limescale deposits.

Necessary Supplies

In order to modify an element you'll demand the post-obit:

• Garden hose
• H2o heater element wrench
• Voltage tester
• New heating element with "O" ring

Replacing a Heating Chemical element

• Release the hot h2o force per unit area by allowing air into the tank. To practise this, open a nearby faucet. Only open up the hot water tap, not the cold. Be sure to get out the tap open.

Step 4: Remove the Access Panel Embrace

• Use a screw driver to remove the comprehend of the access panel. The upper panel houses the upper water heater element. The lower panel houses the lower element.
• There's usually insulation between the console door and the thermostat. Set the insulation aside in a dry identify.
• The thermostat should have a plastic cover. Gently remove the embrace.
• Check the wires with a volt meter to ensure that in that location is no power.
• Inspect the wiring. Has whatever of the wires been damaged? Are there whatsoever melted parts? Wiring can be damaged if sediment has acquired an element to overheat. Any damaged wiring must be repaired.
• Loosen the screws and disconnect the 2 chemical element wires from the heating element.

Stride 5: Remove the Heating Element

• Use a heating element wrench to remove the element. It's designed specifically to remove electric water heater elements, and has a wide oral cavity that fits over the exposed part of the element.
