Everything You Need to Know About Water Heater Elements

Water heaters are essential home appliances that provide you with warm water for daily use. An essential part of any water heater unit is the water heater element, which is responsible for heating the water. This guide dives deep into what a water heater element is, how it functions, the different types available in the market, and how to choose the right one for your needs.

Understanding the Water Heater Element

The water heater element is a crucial part of any water heating system. It is typically made of metal and is designed to heat up when electricity is passed through it. This heat is then transferred to the water that circulates around it, providing you with hot water in your taps and shower.

Different Types of Water Heater Elements

When you start looking for a water heater element, you will find that there are different types of elements available, each with its unique aspects. Here's a look at the most common types:

• Incoloy Sheathed Elements: These water heater elements are highly durable and can withstand a significant amount of heat and pressure. They come with a protective outer layer to prevent electrochemical reactions.

• Copper Sheathed Elements: Copper sheathed elements are known for their superior heat conductivity, making them highly efficient. However, they may corrode over time, especially in areas with hard water.

• Nickel-Based Alloy Sheathed Elements: These water heater elements are popular choices due to their resistance to scaling and high corrosion resistance. They are ideal for hard water conditions.

Choosing the Right Water Heater Element

Choosing the right water heater element requires consideration of numerous factors such as heat output, durability, resistance to corrosion, cost, etc. Here is what you need to know:

Heat Output

The first thing to consider when choosing a water heater element is the heat output. The heat output refers to the amount of heat the element can produce within a specific period. High wattage elements heat water quickly but consume more energy, while low wattage ones are energy-saving but heat water slowly.

Lifespan and Durability

When investing in a water heater element, another factor to consider is its lifespan and durability. Incoloy sheathed elements, for example, are durable and can withstand a significant amount of heat and pressure.

Resistance to Corrosion

The water heater element's resistance to corrosion is another important factor to consider. Hard water can cause water heater elements to corrode over time, reducing their efficiency.

Installing a Water Heater Element

Installing a water heater element is a process that requires certain technical skills. It's always recommended to hire a professional for this task. However, if you opt to do it yourself, always remember to switch off the power supply and drain the water heater first to avoid any accidents.

Maintaining Your Water Heater Element

Regular maintenance of your water heater element is crucial for its longevity and optimal performance. This involves cleaning the element regularly to prevent scale build-up and replacing it periodically if you notice a decline in water heating efficiency.

Understanding the water heater element is essential for every homeowner. It helps make informed decisions when needing a replacement, ensuring you get the most durable, energy-efficient, and cost-effective solution.

Frequently Asked Questions about Water Heater Elements

If you have any queries about water heater elements, our following FAQ section should provide some helpful responses!

Why does a Water Heater Element burn out?

A water heater element burns out due to different reasons. The most common one is sediment build-up. The hot water that leaves the tank is naturally replaced with cold water. This continuous heating process results in a sediment build-up that eventually causes the heater element to fail. Other causes include overloading, aging, and faulty wiring.

How can I check the Water Heater Element?

Checking the water heater element can be done by a multimeter tool. Turn off the breaker for the water heater, then remove the cover plate and insulation. Afterwards, test for the presence of voltage. The meter should read zero. Once you determine there's no electricity passing through, you can test the element for continuity. A good element will have a reading between 5 and 25 ohms. An element that does not have continuity is defective and should be replaced.

When should I replace the Water Heater Element?

You should consider replacing your water heater element if there's a significant decline in the performance of your water heater, if your water isn't heating at all, if there's rust on the elements or if your multimeter testing indicates that the element is faulty.

Can I replace the Water Heater Element by myself?

Yes, you can indeed replace the water heater element by yourself, but only if you are comfortable working with electricity and plumbing. If you aren't, hiring a professional is highly recommended.

What is the cost to replace a Water Heater Element?

The cost to replace a water heater element may vary depending on several factors, such as the type of the element, the geographic location, and the professional hired for the task. However, generally, the cost ranges from $200-$300 including labor charges.

How long will my Water Heater Element last?

On average, a water heater element should last for about 6-10 years. However, this depends on the water condition, the material of the element, and the maintenance program followed. Regular maintenance and inspection can significantly increase the lifespan of your water heater element.

What are the types of Water Heater Elements?

The two basic types of water heater elements are the metallic and the non-metallic elements. Each has its own advantages. The metallic versions are more common and more affordable, but on the other hand, the non-metallic ones are generally more durable and resistant to burnout.

Can I run my Water Heater without an Element?

Technically, yes, but it wouldn't effectively heat your water. The element is a critical part of the water heater unit. Without a functioning element, the water heater cannot heat water adequately which is its primary function.

Why is my Water Heater Element leaking?

The most common reason for a leaking element is usually a loose element. Over time, it can get loose due to contraction and expansion caused by heating water. In this case, tightening can solve the problem. If tightening does not fix the leak, then it could be a sign that the gasket needs to be replaced, or the tank itself may be corroded and need replacing. In all situations, it is best to hire a professional to evaluate the problem and to prevent the risks associated with leaking water heaters.

Pros and Cons of Water Heater Elements

Pros of Water Heater Elements
