Tubular heating element for the water heater what it is

You can’t have a warm and comfortable home without a trustworthy water heater. Have you ever thought about the technology that powers it, though? The tubular heating element is one of a water heater’s most important parts. We’ll go into detail about what a tubular heating element is in this article and how it improves your water heater’s efficiency.

First, let’s dissect it: a cylindrical object that becomes heated when an electric current flows through it is called a tubular heating element. Consider it the engine of your water heater, bringing the water up to the temperature you want. Typically, these elements are composed of metals that are known for their strength and resistance to high temperatures, such as copper, stainless steel, or Incoloy.

You may be wondering how this heating element with a tubular design actually works. Well, it’s really very easy. Heat is produced by electricity passing through the heating element when your water heater is turned on. The water around the element then absorbs this heat and becomes warmer until it reaches the desired temperature.

However, why employ a tubular heating element in particular? Its effectiveness is among the primary explanations. Because tubular elements are made to heat uniformly, every drop of water will be heated to the same temperature. This helps to reduce energy waste as well as speed up the heating process, which will ultimately save you money on your utility bills.

In addition, the durability and dependability of tubular heating elements are well known. Tubular elements have fewer moving parts than some other heating techniques, like gas heaters, which lowers the possibility of malfunctions. You can feel secure knowing that your hot water supply is in capable hands because this will result in fewer repairs and a longer lifespan for your water heater.

In the world of home heating and insulation, understanding tubular heating elements for water heaters is essential. These elements are crucial components in water heaters, responsible for heating the water you use for various household tasks like showering, washing dishes, and doing laundry. Essentially, a tubular heating element is a long, cylindrical device made of conductive material, often metal. It works by using electrical resistance to generate heat, warming the water as it flows through the water heater. Think of it like a long coil inside your water heater, heating up when electricity passes through it. This heat transfers to the surrounding water, ensuring you have hot water whenever you need it. So, when you"re thinking about your home"s heating and insulation, don"t forget about the importance of understanding and maintaining your tubular heating element for efficient hot water supply.

Tubular heating elements for boilers

Tubular electric heaters were created in the middle of the 1800s, and during the course of their 158-year existence, they developed into an essential component of numerous home appliances that actively heated water. The water heater is the most important component. Without it, washing machines and dishwashers cannot function normally, and without it, no electric boiler can heat water.

Purpose and variety

Tena is the most important component of any water heating device. Because they are powered by the electric network, designers utilize them to create a wide range of electric heating appliances, from automated large capacity boilers to traditional kettles.

A constructive water heater ten is a hermetically sealed copper pipe with an internal nichrome spiral. It is typically found in the product’s lower section, though it can also be accessed from the side in certain situations. Because the entire volume of water is heated uniformly at the lower location, it is more tolerable.

There are two types of heaters: "dry" and "wet," depending on the design. The former are so named because a hermetic flask conceals their bodies and prevents them from coming into contact with water. Modern models of water heaters use Dry Ten. The absence of scale and lime deposits greatly extends the life of the heater, which is why manufacturers believe this design to be more durable because the housing of the heating element is not constantly exposed to water. If the user inadvertently turns on the boiler without water, they won’t block.

Nonetheless, the Wet or Immersed Ten model is thought to be the most popular. Some users think that this is an outdated model that is being used in vain because it is still being used in different water heaters everywhere. The primary drawback of this type of heater is its propensity for frequent malfunctions brought on by deposits and scale, but in comparison to their dry counterpart, they are easier to find on the market, simpler to replace, and naturally less expensive.

Design features

The following components make up the wet heater’s standard design:

  • hollow -bended copper or stainless tubes curved in different ways;
  • Inside there is a spiral of a nichrome thread;
  • The insulator is thermal system – quartz sand or magnesium oxide.

A closed or dry boiler heater can be identified by the inclusion of an insulating flask made of stronger ceramic. Its body is occasionally composed of inorganic steatitis or magnesium silicate rather than metal. The heating process takes place via this protective flask, and since the tubular element stays out of the water, it lasts a long time.

If we reason, which of the types of heating elements is better, then it should be noted that there are very significant differences in power and configuration – for wet elements, there are differences in the mounted fastening, forms of bending and materials for the manufacture of the case. The type of tank used in the boiler determines The shape of the heater – according to this characteristic, an electric heater can be made direct species or bent, in various directions. Basically, a wet -type Ten is made of copper and stainless steel. Dry Ten for installation in a boiler is made in the form of a direct rod of different lengths and diameter – it depends on the volume of the tank, the case is made of stainless steel, and the steatite coating is made specifically for each model.

Difficult choice

When purchasing a water heater, users often wonder what kind of heating element is best for their boiler. You must become acquainted with their operational features, at the very least, in order to accomplish this.

All heaters in products are installed standard, flange type. As a result, total contact with the heated liquid is established; however, during operation, deposits keep appearing on the case due to corrosion products. greatly reducing the heat transfer’s impact.

Over the course of operation, the heating process gets more intensive, which raises the amount of electricity used. Manufacturers’ designers employ a variety of enhancements to delay the formation of deposits and scale, but wet heating elements exhibit rapid characterization and require intricate maintenance.

Since the body of a dry heater is rarely in contact with heated water, they have a longer service life. Special enamels based on titanium or fiberglass are applied to the inside of the tank capacity and the flanges of the heater fastening. This corrosion protection stops deposits and scale from forming.

Wet type heat heaters age with prolonged use, which increases the risk of a breakage and an electric shock to the user via the product casing. Such a negative possibility is eliminated in the dry version due to the installation of a ceramic flask, which acts as a dielectric, between the fluid and the heater body. Moreover, this option totally prevents the heater body from overheating, minimizes maintenance, and does not exclude periodic replacement—just much less frequently.

Two types of Ten have been used simultaneously by many manufacturers to start large-scale water heater production, which increases service life and reliability.

According to statistical data, closed heating elements operate for three times as long as their open counterparts—wet for no more than five years and dry for at least fifteen. Open heaters are less expensive and more useful for repairs, but it is preferable to go with a dry option if you do not intend to maintain your water heater.

What heaters are produced

To select the same heating element for your boiler, you must be aware of the features that distinguish different models of water heaters from one another.

The well-known company from sunny Italy favors heaters made of stainless steel that have a chromium content. however, it has a copper shell. Because the flange is made of brass, there is a minimum 1.5 kW increase in thermal power. All water heaters, including small species and folios intended for capacities greater than one hundred liters, use the heating element of this performance.

Two different kinds of heaters are supplied simultaneously by another Italian company. which drastically cuts down on the amount of time it takes to heat water. One has a power of 1 kW, while the other is 1.5 kW. The user can choose how they operate in tandem or separately to customize the heating process. The composition of the alloy used to make the case is kept a secret and is the subject of a registered patent. Fantastic bonus: you can use a heating element from another manufacturer, like Atlantic or Guarantee, in place of them.

The Slovenian company uses heaters of the tubular type, but they are shielded from fiberglass or vitreous icing. like enamel covering the container’s interior surface. As a result, developers effectively combat the emergence of scale and lime plaque, which causes this part to malfunction frequently. In order to prevent the heater from burning out when replacing and installing a heater from a different manufacturer, the user must be lowered to 60 degrees. The water heats up to an optimal temperature of 90 0 C.

Arising problems

We provide a short list of typical issues with heating element operation.

  1. When cold water runs from the tap, this is a signal that there was a violation in the connection of the heater – thermostat.
  2. If the product then turns on and then turns off – this is the first signal that enough has formed on the heater Fat scale or layer of lime plaque.
  3. When, with independent installation, the user made various errors due to inexperience, then a very impressive may occur in the container air bag. which does not allow the heating heating water.

It is far easier to detect a malfunction than to fix it, even with the right resources and effort.

Replacement algorithm

The replacement of the water heater’s heater is an extremely labor-intensive procedure that must be done precisely in accordance with the following rule:

  • turn off the product from the electric network;
  • make a complete drain of water;
  • remove the water heater from the mounts and turn it over for the convenience of all the work;
  • unscrew the mounting of the lower panel, photograph the location and the procedure for connecting the wiring;
  • Disconnect the wires from the heater and extract it from the tank body;
  • Clean plaque and scale, if no damage to the housing is detected, then install the heating element in place;
  • In the case of replacement, we install a new heater, make the assembly in the reverse order.

To assist novice users in performing such an operation accurately, a video plot featuring an experienced master replacing Ten in a boiler is available:

Without the use of specialized heating elements, no device designed to heat water could function. Ten is the most crucial part of this apparatus for a water heater.


In order to heat the water in a boiler or boiler, ten heat heating elements are required. Water heater Types of Ten:

  1. Wet (ATT – VTT, Electrolux Ewh Centurio, ASF);
  2. Dry (AEG, ISEA, TESY, Ariston Ti Tronic Best).

The location principle is what primarily sets them apart. Water is directly affected by wet heating elements. This considerably shortens the validity period while also speeding up the heating process. Scale and rust develop on a metal heater as a result of the water’s altered chemical composition.

The dryers that are supposedly more widely used. They are kept safe from direct water contact by being enclosed in a protective shell. They have a longest validity period, unlike wet models, but at the same time, the heating time is slightly increased. Although a dry heater for a water heater is slightly more expensive than a wet one, you can save money on parts by purchasing such a device.

Models with a traditional tubular heater and stearite are also currently available. Their constructive performance is where they diverge. Nearly every water heater made in the past, including the Electrolux Centurio, Electrilux, Guarantur, Polaris, and many more, had Trumpid heating elements. They are a pipe with a Mr. and a unique heating metal spiral. It is enclosed in a protective copper or stainless steel shell. One heating element in the tube is protected from combustion and short circuit by another. Its dielectric composition enhances the element’s thermal conductivity while preventing the formation of closes.

Often, the second tube is omitted and quartz or magnesium oxide is injected internally into the body. Contact rods are covered with ceramic or stainless steel for added protection of the contacts. When a water heater is in continuous use and exposed to water, this is most frequently utilized. Nearly 90% of the electric energy is converted into thermal energy because of the heating element’s high resistance. The acquired heat is transferred to the electric heater of the accumulative or flow heater, assisting in raising the water’s temperature.

Electroten steatite type (Wester Whe, oasis) has a slightly different structure. It is represented in open form, where steatite wires play an important role, this is ideal for summer water supply. They are located along the ceramic cylinder. This cylinder is covered with vertical cavities, into which wire is wound. It has very high strength indicators, but due to a great danger in use, it is used only in heaters with a thermostat. Wire heating can reach 800 degrees with a minimum indicator of kW. It should be noted that such a ceramic heater can heat the water area unevenly, which allows the use of an electric element to ensure the heating of water in an asymmetric tank.

In this instance, fats and other harsh chemicals must be kept away from the steatite heater of an electric water heater. It is very challenging to clean.

So, what precisely is a water heater’s tubular heating element? To put it plainly, it’s an essential part that warms the water in your heater. These components are usually made of metal, most frequently copper or stainless steel, and are intended to survive extended use and high temperatures.

The efficiency of tubular heating elements is one of their main advantages. You will always have hot water because of their ability to heat water fast and efficiently. They are a popular option for water heaters in homes and businesses because they are also reasonably simple to install and maintain.

However, efficiency isn’t the only benefit. Long-lasting and robust are other qualities of tubular heating elements. They don’t break down or lose their effectiveness over years of use, in contrast to some other heating techniques. This durability lessens the inconvenience of regular maintenance in addition to saving you money on replacements.

Heating elements made of tubing also have versatility. Whether you have a traditional storage tank or a tankless model, they are available in a range of sizes and shapes to fit different kinds of water heaters. They can be used in a variety of settings, from big commercial systems to tiny residential units, thanks to their adaptability.

To sum up, tubular heating elements are essential to maintaining the efficiency of your water heater. They guarantee comfort and convenience in your house or place of business by delivering dependable hot water whenever you need it thanks to their effectiveness, robustness, and adaptability.
