Types of Immersion Heaters

Immersion heaters are widely used in households to heat up water cylinders for various purposes. There are different types of immersion heaters available that vary in their design, size, and heating capacity. In this section, we will discuss the most common types of immersion heaters and their characteristics.

Screw-in Immersion Heaters

Screw-in immersion heaters are the most commonly used type of immersion heaters in water cylinders. They heat water by screwing into a threaded aperture at the top or side of the cylinder.
They come in a range of sizes and wattages to suit different cylinder sizes and heating needs. One major advantage of screw-in immersion heaters is that they are easy to install and replace, making them a popular choice among homeowners.

However, they may not be suitable for all types of water cylinders as they require a threaded opening for installation. Moreover, if not installed properly or with incompatible cylinder models, screw-in immersion heaters can cause leaks or damage to the cylinder.

Flange Immersion Heaters 

Flange immersion heaters are another type of popular heater used in water cylinders. Bolted onto cylinder side or top flanges, unlike screw-in immersion heaters. An O-ring seal inserts an electric heating element in a metal sheath into the flange.

Flange immersion heaters can be cleaned or replaced without depleting the tank’s hot water supply, making them excellent for maintenance. Flanged immersions (typically stainless steel) survive longer because the heating element doesn’t touch the water.

Over-The-Side Immersion Heaters

Over-the-side immersion heaters are generally used for smaller water tanks, such as those found in aquariums, laboratories, or small tanks that have no openings to accommodate other types of heaters. They are called “over-the-side” since they hang over the side of the tank and heat up the water from outside. Unlike other types of immersion heaters, over-the-side ones require no special tools or fittings to install or remove.

They come with adjustable brackets that can be clamped onto the lip of a tank and lowered into the water. Once installed, they can be easily positioned to change their heating area’s orientation.

That concludes our discussion on the different types of immersion heaters commonly used in water cylinders. The next section will cover pre-installation preparations before installing these heating devices.

Pre-installation Preparation

Choosing the right type of heater for your water cylinder

Before installing an immersion heater, it is important to choose the right type that matches your water cylinder. The three common types of immersion heaters are screw-in, flange and over-the-side heaters. Screw-in heaters are relatively smaller in size and are screwed into a designated hole on the cylinder’s wall.

Flange heaters are larger and require a mounting flange installed on the wall of the cylinder. Over-the-side heaters rest on top of the water level inside a cylinder.

Consider your water cylinder size and daily hot water usage before choosing a heater. Screw-in immersion heaters fit well in tiny water cylinders.

Measuring the length and diameter of the heater to ensure proper fit

One crucial step before installation involves taking accurate measurements for both length and diameter to ensure that your chosen immersion heater fits into your water cylinder perfectly. It is recommended that you double-check these dimensions before purchasing an immersion heater.

Some cylinders come with specific measurements already recorded in their manual or printed in their label. If these aren’t available, measure directly from within or outside using measuring tools such as tape measures or rulers.

Checking voltage and wattage requirements

Another essential factor when choosing an immersion heater is checking voltage and wattage requirements. Commercial buildings get 440 volts or more, whereas most residences get 220-240 volts. High-wattage immersion heaters need more electricity to heat than low-wattage ones.

This feature should be considered when choosing a type of immersion heater with different wattage ratings. By considering these technical specifications, you can be sure that your chosen immersion heater is compatible with your cylinder’s electrical supply and won’t pose any danger to your home.

Installation Process

It’s important to ensure all of it has been drained out before proceeding with removing an old immersion heater or installing a new one, otherwise, there could be serious consequences like electrocution.

Removing old or damaged heater (if applicable)

If you are replacing an old immersion heater which needs removing first, this involves unscrewing it from its socket in most cases located at upper part of tank under insulation material inside a protective sheath or unwiring it completely depending on how it was attached within heating element assembly. If you are unsure about how this task should be performed safely and correctly It’s best practice to seek professional help.

Installing new heater by screwing it in or attaching with flange

At this point, you can install the new immersion heater into your water cylinder by screwing it in or attaching it with a flange. Care should be taken to ensure that the heater is placed in the right position and is properly aligned. If you are using a screw-in type of immersion heater, it’s recommended that you use plumber’s tape on its threads for better sealing and avoiding leaks.

Filling up the cylinder with water

Once the new immersion heater is installed correctly, fill up the cylinder with water. Turn on your hot tap or faucet which will allow air to escape as hot water flows out until fully refilled taking care not to overfill it and create an explosion risk due to thermal expansion of heated water content. With these steps successfully completed, you can now turn on your home’s breaker box again and enjoy hot water flow from your taps or faucets once more!
