How Does The Water Heater Element Work?

When the water is cold, the built-in thermostat of the water heater sends electrical current to the water heater elements. Generally, water heaters feature two heating elements. Firstly the top one activates and warms up the half water. Then the lower element activates and completes the job. Once the water has reached the required temperature, the thermostat ceases the flow of electrical current.

Why Do You Require The Best Water Heater Element For Hard Water?

By hard water, we basically mean water, either High concentration of magnesium & or calcium. If the water heater conditions hard water, it will leave sediments (calcium deposition) behind. Such sedimentation can obstruct the whole communication between the thermostat & the water element. It can ultimately lead to water heater dysfunction and even explosion. Only a high-end water heater element can survive through the sediment build-up.

How To Choose The Best Water Heater Element For Hard Water? 

Choosing the most suitable heating element for the water heater is certainly not easy. You have to match it up with the style of the water heater. Other than that, there are many other factors to consider like – material, wattage, attachment, or any other features. Let’s check out below as we have discussed that below in detail! 

Tank Or Tankless: 

Before choosing a water heater element, you must be clear about your requirements. Tankless water heaters are highly portable, affordable, and energy-efficient. On the contrary, tank water heaters offer a good solution for storing water up to 50 gallons. Depending on your heating system, choose the most suitable element.


Checking out the material of the element is necessary indeed. Go for the material which has a high strength to bear sedimentation.


Choose the correct wattage before investing in the best water heater element. If the element wattage is lower than the heater wattage, the element won’t heat up the water on time properly. If the element wattage is higher than required, then it will function too much & drain early.

Attachment Type: 

The most common attachments are –

Flange Type: 

Flange-type attachments feature four small bolts.

Threaded Type: 

If you have a modern water heater, a threaded attachment will be the best one. Take a large wrench and install the water heater elements and install them on either side of the tank with two bolts.

Energy Efficiency: 

The most energy-efficient element will offer the best performance at a low cost. So, be very careful while choosing the heating element as the electricity bill is a major point of consideration.


Nowadays, the High-quality water heating elements feature special technology to prevent sedimentation. Such technologies include – mineral deposition reduction or inhibition.

Besides, you can also focus on other factors like – flow rate, first-hour rate, or recovery rate.


How long do electric water heaters last with hard water? 

Hard Water can greatly affect the overall longevity of the electric water heater. That’s because – hard water causes mineral deposition leading to decreased efficiency. According to our research, limescale build-up can reduce the heater’s lifespan by up to 2 years. 

Which water heater element is best? 

Among different types of water heater elements, the ultra-low density heating elements are the best indeed. They are made up of stainless steel or nickel and can easily bear sedimentation. Even though they are energy efficient, they are relatively pricey. 

From the overly concentrated market, we would recommend Dernord 240V 6500W ultra Low-Density element as the best one for its superior compatibility and convenient threaded attachment. However, if you have a low budget, go for Camco 240V Low Watt Density Water Heater Element; it is highly affordable yet functional against sedimentation as well.

How to protect the water heater from hard water? 

Hard Water contains excess minerals, especially calcium, which is harmless to our body but can largely reduce the efficiency of water heaters. The most effective way to protect the water heater from hard water is to install a water softener. It will prevent calcium deposition not only in the water heaters but also in the whole plumbing system.

Final Verdict

What is the best water element for hard water? What To look for in the best water heater element? Will you go for a high density or a low density one? I believe you have already found answers to all of these queries. In our content, we have listed only the premium quality water heating elements of 2022. 

However, among all, we would recommend the Suburban 520900 Water Heater Element & Camco 240V Low Watt Density Water Heater Element for their efficiency and performance.
