Immersion Heaters, which are mechanisms that make it possible to heat water electrically for any reason, are preferably a system that is mounted in a container or tank. Immersion heaters, which are relatively inexpensive in terms of purchase, can be used in a variety of ways. In this article, we'll talk about how much electricity immersion heaters use, whether it's cheap to leave them on all the time, how they work, and whether it's safe to leave them on.

The immersion heater uses electricity to operate. This is a relatively costly method as electricity is relatively more expensive than gas. The phrase “use a lot of electricity” here depends on how many kW and how much you use the device, and most importantly, what you compare it to. Naturally, an immersion heater uses a lot of electricity compared to a light bulb, while it uses very little electricity compared to a generator. The most important thing here is what you compare the immersion heater with and how many kW of immersion heater you use.
Although using an immersion heater is convenient, it is more costly than gas. Technically speaking, using 1,000W of electricity will cost you 15p, while using 1,000W of gas will cost you around 4p. This means this. If an immersion heater operating with 1kW electricity consumes 15p of electricity per hour and the user uses this device for 5 hours a day, it will cost 75p per day, £5.25 per week and £21 per month. If you want to fast all day, it will cost you £3.60 per day, £25.20 per week and £108 per month.
You are the decision-maker here. Therefore, only users can decide whether these amounts are economical or not. Because this situation is completely relative. However, if this situation seems costly to you, we cannot say that there is no solution. For example, thermostatic control and insulation will increase the efficiency of your device. This will reduce your cost. Another method to reduce your cost is to use your immersion heater at times when the intensity is relatively low. In some cases, using your device at these times can cut your cost in half.
We can say that an immersion heater is a mechanism that is connected to a tank or a container utilizing a resistor powered by electricity and used to heat water.
Even though the working principle varies from model to model, immersion heaters are made by wrapping a resistant heating wire in a ceramic structure surrounded by copper, cast iron, Incoloy, titanium, steel, stainless steel or PFA coated sheath. Electricity moves heat through the ceramic jacket, and the heat from the jacket quickly heats the water or liquid surrounding it. The heated water is ready for use no matter what purpose it is heated. What is mentioned here is the working principle of immersion heaters.
The temperature values that Immersion heaters can give may vary. The variability mentioned here depends on the supply voltage of the device and also on the resistance. Heaters used for industrial purposes can generally heat water up to 209 kelvins. The resistance measurement of the heater is constant in any case. Therefore, the heat output remains constant regardless of the application and environment.
There are types of immersion heaters for different purposes. These types are siding immersion heaters, flanged immersion heaters and screw immersion heaters. Side immersion heaters are the most useful in cases where a large working area and portability are important in terms of cleaning and easy removal of tanks. Flanged ones are useful for irregularly shaped containers due to their large watt densities and heating outputs, and flange dimensions and grading. Finally, screwed ones are suitable for process water heating and frost protection.
So who uses these devices? Many people own a boiler to heat water. Some people prefer to use an immersion heater as a backup water heater if their boilers are old or unsafe. These devices can even be used as the main hot water source.
There are also different alternatives for hot water. The important thing here is the cost for you in every respect. Because no matter what, it is always cheaper to heat water using gas than to heat it using electricity.
Immersion heaters, whose prices vary according to their type and volume, even depend on the number of rooms in the house you live in. You need to buy the hot water storage cylinder separately. And you should have it installed by a professional, otherwise, it can have unpredictable bad results. However, the installation costs are quite cheap.
But how can I choose which heater I need? The answer to this question depends on the volume of water you need and the required temperature rise to meet the needs of your home. Prices may vary depending on brands and your region.
Installing an immersion heater device or replacing an existing device with a different one is generally a quick task. Here, small parameters such as the distance of the expert team you receive support from and unexpected problems determine how long the work will take. However, we can say that the range of variability is 1-2 hours to almost half a day. It will be the best way for you to get technical support in order to make this change. If you do not have sufficient technical knowledge and sufficient practical knowledge, it is definitely not recommended to do this job on your own.
Let's start with a clear answer to this question, it's definitely not safe. We can talk about a few big problems that may arise if you leave your Immersion heater on all the time.
Firstly, your immersion heater may stop working completely and this can lead to huge costs. We strongly recommend that you do not leave your device open, as it may permanently damage the tank or container it is in.
Secondly, the water in the cylinder in the immersion heater mechanism may boil. This situation is dangerous. Because the water boiling there will then be pushed into the cold water tank by the cylinder. In this case, only boiling water will flow from your fountains, even if you turn the cold side. Even when you turn on the fountain to wash your hands without being aware of this, you will be doing yourself a lot of work, and serious burns may occur on your skin. While taking your daily shower, you may suddenly encounter boiling water and burn almost your entire body. Burns that may occur on your skin will cause serious harm to you both in the short term and in the long term. So much so that even your own life is in danger when faced with such a situation.
In addition to what we have mentioned above, leaving your immersion heater on all the time is extremely costly. Due to these and similar reasons, even one hour may be sufficient for a few hours at night, depending on its quality and mechanism. If you leave it on, it will provide you with a sufficient amount of hot water for most of the day.
