INTRODUCTION
Ceramic heaters are a breath of fresh air. They’re extremely good at absorbing and releasing heat and come in various types. Here, we will delve into the details of their working principle and use cases.
What are Ceramic Heating Elements?
Ceramic heating elements are a special kind of heating element made from advanced ceramic materials. Materials like zirconia (ZrO₂), silicon nitride (Si₃N₄), and alumina (Al₂O₃) make them display exceptional performance in heat conduction and electrical resistance.
They’re well-built to comfortably resist electrical current and, in the process, release heat into the atmosphere. They conduct heat through a network of ceramic plates attached to coils of metal.
Fun fact is, you can use them anywhere - industries, offices, sitting rooms, kitchens, and even as personal gadgets. Ceramic heating elements primarily help you produce heaters, ceramic heaters that can withstand high temperatures and efficiently conduct heat.
Industrial baths, electric water heaters, and oil preheaters all use high-temperature ceramic heating elements. It’s one easy and sure way to indirectly heat liquid. Ceramic heating elements are produced from silicon carbide, aluminum, and boron nitride due to their strength, durability, and high thermal conductivity.
Some common examples of ceramic heating elements are space heaters, toasters, electric water heaters, and ovens. All these can maintain a steady temperature while performing effectively.
Here are some of the properties that have made ceramic heating elements so vital today:
-
They have high strength and excellent heat dissipation.
-
They are very ductile; hence, you can easily form them into any shape you want.
-
They have a high melting point.
-
High-temperature ceramic elements exhibit controlled heating and durability.
-
They have a very high stability.
-
They don’t rust easily.
-
They have a great resistance to electricity, thermal shocks, deformation, and cracks.
-
They are good thermal conductors
How Does a Ceramic Heater Work?
Aluminum, iron, chrome, or nickel chrome wires are the major components of ceramic heating elements. This allows them to comfortably operate using the “Ohmic principle” of electrical resistance. They work using conductive, convective, and radiative heating.
How? - Whenever a ceramic heating element or ceramic heater receives electrical current, there’s a significant resistance. This resistance generates heat as a byproduct. It’s an energy-saving process that maximizes resistive loss to produce heat, hence, transforming this “supposed lost” electrical energy into thermal energy. Yes, it’s that simple! With this, you can solve your heating needs any time, any day.
Ptc heating elements, water heaters and other ceramic heaters operate in this manner every time.
Types of Ceramic Heating Elements
There are four main types of ceramic heat elements available today:
-
Positive Temperature Coefficient (PTC) ceramic heaters: These Ptc heating elements are well known for changing dynamically with temperature. You can trust them to self-regulate themselves.

However, you must understand that at times during operation, they could get noisy. Also, it’s important to keep them clean to increase their lifespan and prevent the spread of dust and harmful allergens.
Comparison Between Ceramic Heating Elements and Metal Heating Elements
Metal heating elements are no match for ceramic heating elements in many aspects. If you’re considering which of them to purchase, in terms of their performance output, efficiency, and durability, think no further.
Ceramic heating elements use more advanced ceramic materials as a major component, whereas metals use special metal alloys instead. As such, ceramic heating elements can heat more quickly and efficiently than their metal counterparts.
It doesn’t end there; ceramic elements have better lasting power, strength, and durability compared to metal heating elements. Also, it’s easier for you to shape a ceramic element into any form than a metallic heating element.
Ceramic heating elements are costlier compared to metallic heating elements. However, they’re worth buying, due to their versatility and safety. Metallic heating elements are way more limited in usage compared to these ceramic heater coils.
Ceramic heating elements, compared to metallic heating elements, can also handle temperatures reaching 1,600°C while giving uniform heat. The fun part is that they hardly get rust, but you can’t say the same for metallic heating elements.
Ptc heating elements will even help you self-regulate their temperature, whereas metal heating elements do not perform that way.
That said, the choice is yours, depending on your budget and the outcome you desire. These heating elements are available to serve your heating needs.
