Heating Up: The Advantages and Applications of Resistance Heaters

Introduction:

Resistance heaters are an excellent heating source for those looking to reduce their energy consumption and enjoy the security of cooking at home. Deciding which type or model is best for you can be challenging with so many options.

The following article will summarize the different types, applications, and some Advantages of Resistance Heaters that help you understand the different types and what they are best suited for.

What is Resistance Heating?

Resistance heating is a type of electric heating in which the material's resistance produces the necessary heat. This electric heating technique is widely used in all aspects of heating, including cooking, water heating, and even space heating.

In resistance heating, a material with low resistance is used for the return, while a body or substance with high resistance is used for the supply.

Principle of Resistance Heaters

To release energy in the form of heat when an electric current is passed through a material with high resistance, the electrons must collide with the positive atoms of the material. It is also known as "Resistance Heating'' when used to describe this heating process.

Types of Resistance Heaters

Resistance heaters generally fall into two categories:

01. Direct Resistance Heating

Direct resistance heating is a type of resistance heating in which the charge (a substance to be heated) flows through the electric current directly for the amount to heat up due to its resistive effect.

Advantages of Direct Resistance Heating

There are several advantages of direct resistance heating. Some of them are given below.

● Direct resistance heating has very high efficiency as no heat transfer is involved.

● The heat generated per watt is very high indirect resistance heating.

● The maximum amount of heat is generated at the working temperature, and it is uniform throughout.

Applications of Direct Resistance Heating

Direct resistance heating is used in almost all electrical applications to produce heat. Some of the standard applications are given below.

● Salt Bath Furnace

● Electrode Boiler

● water heaters and more

02. Indirect Resistance Heaters

Indirect resistance heating is a type of resistance heating in which the electricity supply passes through the resistive material (resistive body) and then returns through the highly resistive return line to the source.

Advantages of Indirect Resistance Heating

There are several advantages of indirect heating. Some of them are given below.

● The efficiency of indirect resistance heating is much better than direct resistance heating.

● The maximum amount of heat is generated at the working temperature, and it is uniform throughout.

● No energy losses occur in indirect heating as compared to natural resistance.

Applications of Indirect Resistance Heating

Indirect resistance heating is used in almost all electrical applications to produce heat. Some of the typical applications are given below.

● Resistance Oven

● Immersion Water Heater

● room heaters, electric iron, etc.

Conclusion

From the above discussion, resistance heating is cost-effective and energy-saving. The constant demand for energy-efficient products has led to new developments in resistance heating.

Various types of resistance heaters are available in the market, each with advantages and disadvantages. Therefore, proper research and evaluation must be performed before a decision about which heater to buy is made.
