What Is An Immersion Heater And How Does It Work?

Before making a final selection, there are a few things to keep in mind. Select the best heating system for your home, such as a normal boiler, solar power, or an electric immersion heater. You should consider the ease of use, the type and size of the space, the cost, and other factors when selecting a heater.

What’s the distinction? While solar panels collect energy from the sun and immersion heaters utilize electricity, standard boilers use oil or gas to heat your water. Choosing the option that is best for you is important.

The purpose of this article is to help you determine what an immersion heater is and who does it work.

 

What is an Immersion Heater?

 

An immersion heater is an electric appliance used for heating liquids such as water or oil. It consists of a heating element, usually made of metal such as copper or stainless steel, that is inserted into the liquid to be heated. The element is powered by electricity, which causes it to heat up and transfer heat to the liquid.

Immersion heaters are often used to heat water in a variety of settings, such as homes, hotels, and industrial facilities. They can be portable or installed permanently, and come in various sizes and shapes to fit different types of containers. Some immersion heaters also come with temperature controls, timers, and other features to help regulate the heating process.

There are not only immersion heaters for industrial use, popular heaters are also coil heaters, click here to know what is a coil heater.

 

The Function of Immersion Heaters

 

In immersion heaters, electricity is used to heat the water. The element heats the water as it enters the cylinder. They all have thermostatic controls. You can set the temperature you want and the heater will automatically switch off when it reaches that temperature. Immersion heaters switch back on when the temperature falls below a set temperature.

When setting your timer so that it switches off during peak hours to avoid paying high electricity rates.

 

The structure of an immersion heater

 

An immersion heater typically consists of a heating element, a protective sheath, and a control device.

The heating element is the part that actually produces the heat. It is typically made of a coil of resistance wire that heats up when an electric current pass through it.

The protective sheath is a metal or plastic tube that encloses the heating element and insulates it from the water or other fluid that is being heated. This helps to prevent the heating element from corroding or otherwise deteriorating over time.

The control device is used to regulate the temperature of the fluid being heated. It may consist of a simple thermostat or a more sophisticated temperature controller that can adjust the heating element’s power output to maintain a precise temperature.

In addition to these basic components, immersion heaters may also include features such as a safety cut-off switch to prevent overheating, a timer to allow the heater to be set to turn on and off at specific times, and a digital display to show the current temperature and other information.

 

What are the types of immersion heaters?

 

Immersion heaters for over-the-side use

 

Immersion heaters installed over the side are designed to be used in vessels that cannot install submersible heaters. They install at the top or bottom of the vessel. Also, the face of the heated part is outside. This is a great solution for vessels that cannot have submersible heaters.

Over-the-side heaters are easy to remove and offer plenty of working space within the tank. They are therefore a great choice in applications where submersible heating is not possible.

 

Two-threaded or screw-plug immersion heaters

 

They are also famous for the name of threaded heaters. They screw directly into the tank wall through a threaded hole. Immersion heaters like these are perfect for freezing protection and heating process water. These heaters are a reliable, efficient, and cost-effective way to maintain a desired liquid temperature.

 

Three-Flanged Immersion Heaters

 

One of the most common ways to heat gases and liquids occurs with these heaters. They exist to fit within tanks and vessels under pressure.

 

What are the advantages of immersion heaters?

 

Immersion heaters are a great option for industrial applications. They offer many benefits including:

1. Backup Heat Water

A backup supply of warm water is the main benefit of an immersion heater. You can still use hot water if your boiler fails.

2. Manage your energy use easily

You can turn on and off your immersion heater with a simple switch. You can control your energy usage when not in use. A thermostatic immersion heater will turn off automatically when the water temperature reaches the desired temperature. It will then turn back on once the temperature drops.

3. Save money with an Immersion Heater

Installing an immersion heater with a timer will allow you to set the temperature to be heated automatically at certain times during the day or evening. It is best to use it at night when your energy bill is lower.

 

Immersion Heaters: Uses

 

Electrical immersion heaters have become a popular type of heating appliance because they are environmentally friendly and do not require gas. In order to keep materials from freezing during cold weather, immersion heaters function in a variety of industries, including agricultural, oil, gas, and water treatment, transportation, mining, and transportation.

  1. Nuclear power

The basic use of an immersion heater at nuclear power is to maintain the water pressure in the reactors and create steam.

  1. Wastewater Management

Water temperature is important in wastewater management. Immersion heaters can help to achieve this temperature control. Additionally, the heaters eliminate bacteria that often exist when combining water from various reservoirs.

  1. The Gas or Oil Industry

In cold and harsh weather, immersion heaters can help prevent the oil and gas from becoming gel or wax. In such situations, over-the-side immersion heating is the best option.

  1. Food Processing

Moisture is a breeding ground for bacteria and microorganisms. So, they are used in the food industry to meet government standards and quality standards.

  1. Chemical Industry

In the chemical industry, they use to maintain a certain temperature for chemicals and prevent them from freezing. So, immersion heaters with screw plugs, flanges, and over-the-sides are all used to keep chemicals safe.

FAQS

Q: Why do I need an immersion heater as well as a boiler for my home?

F: Lucky you! If your boiler breaks down or develops a fault, your immersion heat can take over and supply hot water to your home.

Q: What is the main difference between an immersion heater and a boiler?

F: The majority of boilers heat water for faucets and showers using natural gas.

Q: What is the best way to keep an immersion heater running?

F: Yes, if you have unlimited money. If you keep the immersion heater on all the time, it will cost you a lot of money. However, it activates every time the water temperature drops below a pre-set level. If you insulate your hot water tank, it will help to keep the water warm for longer.
