The description above could go on and on about the benefits of a warm shower but look below into the devices that enable you to get these hot showers called immersion heaters.In the morning, you get rid of the night sweats, and the evening one enables you to keep clean sheets.

But who knows what an immersion heater is? Whether you do or not, here is a brief definition.

Definition of an Immersion Heater

From the name of this device, we can gather one thing right away, and that is that it is a device that is immersed in a media to heat it.

And that is precisely what an immersion heater is. In this case of the Immersion water heater, the heating element is submerged in water, and it transmits heat energy to heat the water.

You could place it in a bucket, a tank, or any other container that has water. Some are permanently installed, while others are portable.

An immersion heater’s power could be either source from electrical sources or solar energy converted to electricity. The location of the installation of the immersion heaters of water can be placed in ideally three areas.

And that is the over-the-side, threaded, or flanged. Below are four types of immersion water heaters.

Types of Immersion Water Heaters

Circulation water heaters

One thing about science and how they name their appliances is that what the device does is self-explanatory from the name. For instance, take this type of water heater— you can gather that it works to heat water around the gadget.

The circulation immersion heaters work with two mechanisms. One is through conduction, where the heating rod is heated, and it raises the water temperature in the adjacent water around the rod. The second mechanism that works to spread the heat to other water molecules is through conventional heat transfer.

Here, the heated water molecules rise to the top of the water since they are lighter, and the heavier, cooler molecules fall to the bottom. The circle continues, and with time, the temperature of the water generally rises.

Flange water heaters

flange water heater

The flange immersion water heaters contain more than one type of metal, making the heating rod. The construction of these heaters is rugged, and they are highly resistant to rust due to the materials used to construct them.

They are usually installed by affixing them using bolts to a matching flange welded to the wall or nozzle.

Over the side water heaters

These kinds of immersion heater for bathtub are usually installed over the side of the water container. These immersion heaters’ beauty is that they heat water very fast and are tailored to fit different shaped vessels.

They are also applicable to be installed on a portable water heater and can be moved from one container to the next.

Screw-plug water heaters

Finally, the screw-plug water heaters contain threaded hairpin tubular elements that are connected to an electrical source. You can fix the appliances directly to heat the water. If the lines get ruined, they are easily replaceable.

Now that we know about the significant types of immersion heaters, next, we take a look at five immersion heaters for water one by one.

Immersion Water Heaters FAQ

Is immersion water heater safe?

is bucket heater safe

Yes, it is, but you must follow the safety guidelines to the latter. Some tips are that you completely submerge the heating element inside the water. The second cue is to plug in the machine in an independent socket to prevent electrical discharges that could lead to fires.

The third pointer is never to use the water as it is heating, and that includes any part of your body either partly or wholly.

Fourthly, make sure the container can hold the water even as it boils. The fifth guideline is to unplug the apparatus from the power source before lifting it from the water, and finally, always place the heating water and the heater after use far away from children and pets.

How do immersion water heaters work?

Depending on the type of installation, they will operate differently. But in general, they use two main scientific processes to transfer the energy from one form to the other. The first is through conduction, and the second is convention energy transfer.

Convention entails the energy shifting from the heating element to the water surrounding the device directly. And conventional involves the hotter water molecules moving to the surface of the water and the cooler molecules drop to the bottom.

This cycle of hot water molecules moving up and the cold molecules dropping will eventually even out the molecule’s temperatures. And when this happens, the water will have already become hot.

Some smart heaters automatically turn off at this point, but those without this technology will keep heating the water beyond the boiling point. For the second kind, heating water must be done under supervision.

How long does an immersion heater keep water hot for?

If the external weather is warm, then the water will remain hotter for an extended period.

And if it cold outside the heated water, then it cools faster. Some immersion water heaters have a cycle on and off feature that goes on when the water drops to a certain temperature and turns off when it exceeds a specific temperature.

This on and off mechanism will go on and on as long as the device is connected to power. Admittedly, the immersion water heaters with this feature will keep water hotter longer than those that do not.

How much does it cost to run an immersion water heater?

different types of heater

The cost will always depend on how often you use the device, for what time duration, and the apparatus’s power consumption work. Other factors are the temperature of the water and the surrounding, which fluctuates. The ones with thermostats consume less, thus cost-effective.

Since different immersion heaters have various capacities of watts, they will use different amounts of power. But here is a rough estimate; suppose you have a 3000W immersion heater, and you use it on average 120 minutes daily; that would translate to $1.9 per day and roughly $12.33per week.

Conclusion

In conclusion, now that you have five pieces that you can use as an immersion heater for the bathtub, bucket, kiddy pool, or basin, the ball is on your court.

It is truly a no-brainer since the above five discussed will do a great job of heating the water you can use to take a bath, wash the dishes, or even clean your home.

Get one heating apparatus from the list and forever enjoy using hot water. Remember always to follow the guidelines; they are there for your safety.
