Feature Description
Heating Element An electric component that generates heat when electricity passes through it.
Thermoregulator A device that controls the temperature by turning the heating element on or off based on the set temperature.

Water and heating fires with thermoregulator. TEN and its varieties

The structural component of the tubular electric heater (TEN) is a carbon or stainless steel tube that has a heat-conducting spiral made of the high-resistance material nichrome inside of it. The tube is hermetically sealed and filled with a unique coolant called periclase, which has a high index of thermal conductivity and is also a good insulator. Due to its high pressure, periclase gives the spiral the required shape and, depending on the model, keeps it fixed on the axis so that it does not move when the heating element is bent. The spiral’s ends project outside and are used to attach to the power grid.

There are various methods to group heating foams:

  • According to the type of heating surface they are tubular, finned, rod, flat and ribbon:
  • tubular electric heaters are used in all electric heating devices, in which heating of the heat carrier is the result of conversion of electric energy into thermal energy. They are made of carbon and stainless steel, copper, titanium with length usually from 20 to 600 mm from the tube diameter from 6 to 18.5 mm of any configuration and capacity;
  • tubular electric heaters finned are used in heat curtains and convectors to heat gas or air used to heat the room. Ribs, made of metal strip, are fixed to the steel heating tube with special fasteners perpendicular to its axis. The branched outer surface allows to increase the heat output of the heating element at a lower temperature, weight and overall dimensions;
  • band heaters made of sheet aluminum or stainless steel are used for heating flat surfaces, such as floor heating, but more often in industrial production;
  • flat heaters are produced with a spiral in a ceramic heater for heating flat surfaces also in industry;
  • rod heaters are designed to work in the holes of metal parts.

The heaters can also include sensors for automatic shutdown in the event of overheating and thermoregulators, which range in power from 15 to 15000 W per unit of surface.

Tubular electric water heaters

TENS for water heating usually are made of stainless steel. if used for food products, or copper for water heaters. Although in areas where the water is hard, and in them it is necessary to put heating elements made of stainless steel, as copper quickly fails due to scaling. TENS for water heaters do not differ in design from others, except for increased requirements for tightness and the presence of a thermoregulator in the package. In shape are straight for vertical heaters, and with an additional bend for horizontal ones, so that the water is heated closer to the bottom. Both ends of the tube are mounted on a flange made of brass, carbon or stainless steel.

Heaters for heating

Infrared heaters, heating radiators, and solid fuel boilers are some applications for tubular electric heaters in heating systems.

Solid fuel is not the only fuel used in modern solid fuel boilers. A solid fuel boiler with a thermostat and temperature limiter (TEN) is among the most popular varieties. For example, the heating element keeps the heat carrier’s temperature low at night, making it simpler to bring it up to a comfortable level once the boiler has started. Additionally, it keeps the system from freezing when the solid fuel is completely extinguished by maintaining a specific temperature range.

Both benefits and drawbacks come with using TENS to heat your house. The primary drawback is the price of electricity, which is the priciest form of heat. Furthermore, the electrothene cannot be fixed; in the event that the coil fails, it must be replaced.

Can be linked to the positive points are:

  • autonomous installation of the heating system, if there is no access to gas or solid fuel;
  • automation of the heating process by installing heating elements with a thermoregulator;
  • eco-friendliness of the heating system, as there are no harmful combustion products released into the environment and no fuel to be stored;
  • compactness and possibility to choose a model suitable for the operating conditions;
  • low installation costs and its simplicity.

heating elements for heating radiators

Radiators are equipped with heating elements to keep the coolant at a certain temperature during a brief central heating system shutdown or to heat the coolant further. If the house is equipped with a two-tariff electric meter and the primary source of heat is a boiler that runs on cheap liquid fuel, then having extra heating during the night can be beneficial.

The narrow heating element and thin flange of TENS are characteristics for heating radiators. They come in a variety of capacities and have varying heating element lengths; they are mounted on radiators made of cast iron and aluminum. A protective cover that keeps the heating element dry is included with the package.

Radiator heating elements are robust and dependable because the tube is manufactured with galvanized chrome and nickel. A capillary thermostat makes it possible to precisely control the heating temperature, and two temperature sensors guard against overheating. Modern heaters come equipped with extra features like "Anti-freeze," which keeps the temperature at or below 10 °C for an extended period of time, and "Turbo," which operates at maximum power for quick heating of the space.

Installing the heating element in the radiator is very simple: just unscrew the plug from the heater’s bottom flange, insert the element into the hole, set the thermostat, and connect the power supply to the ground. The tightness specifications should be stated in the device’s passport; otherwise, the radiator could become energized, endangering human life. Benefits of adding TENs to the central heating system include:

  • protecting the room from freezing;
  • protection of the system from damage in severe frosts;
  • economical, because all energy is converted into heat;
  • pulse operation, which saves electricity;
  • high accuracy of temperature regulation;
  • additional useful functions;
  • affordable price.

Heaters with thermoregulator

Every home heating appliance that uses liquid as a coolant has a heating element installed for thermostat-controlled heating. The heating medium’s maximum temperature is 80° C.

The temperature sensor and heating element that make up the TEN with an integrated temperature regulator are combined.

Selection criteria

When selecting an electric heater that is tubular and has a thermostat, there are a few key considerations to make:

  1. Tube material. The body of the heating element can be made of acid-resistant stainless steel or more durable copper. Usually the outer tube has a diameter of 13 mm, but there are also less powerful budget options with diameters of 10 and 8 mm;
  2. Operation in water and weak alkaline solutions. In the device marking, this is indicated by the letter P before the operating voltage designation;
  3. Power. In order not to overload the household electrical wiring, it is better to purchase a heating element with a power of no more than 2.5 kW, otherwise a separate cable with a larger cross-section will have to be laid from the switchboard;
  4. Design of the temperature sensor. In order for a failed temperature sensor to be easily separated and replaced with a new one, it must be located together with the thermo regulator in a separate tube and easily removable from it. Failed thermal sensor makes the heating element turn off at low temperatures.

Scope of application

  • in radiators for organizing temporary heating;
  • in a shower tank, where temporary heating of water is needed.

In other words, the least expensive gadget until it starts to function is the TEN with a thermoregulator for short-term use. Since each device comes with installation instructions, mounting the budget model with components yourself shouldn’t be too difficult and shouldn’t cost more than $5–$6.

Any electrical equipment used for heating purposes includes tubular electric heaters. Science and technology are advancing, becoming more safe, affordable, and capable of performing ever-more beneficial tasks. Additionally, the use of homemade gadgets is declining. Although they are inexpensive to install, they fall well short of factory-assembled gadgets in terms of both performance and, most importantly, safety.

TEG with thermoregulator for water heating

A heating element is used to efficiently convert electric current into thermal energy.

Modern electric boilers, stoves, kettles, and other electric heating appliances use tubular electric heaters.

The nichrome filament inside this apparatus, which runs exactly along the center of the tube and is securely shielded from its surface by a layer of dielectric material, heats up and produces heat. Typically, ceramics are employed as an insulating layer because they effectively transfer heat without enabling electric current to reach the heating element’s exterior.

Pros and cons

Just two of these devices’ few drawbacks—not too much labor resource requirement and impossibility of repair in the event that the heating element burns out—can be highlighted.

There are numerous other advantageous qualities:

In today’s post, we’ll look at a practical and effective way to regulate the temperature in your house using electric heating elements and thermoregulators. Thermoregulator-equipped electric heating elements provide accurate temperature control across multiple rooms, resulting in reduced energy consumption and increased comfort. With this configuration, homeowners can quickly set the temperature to their preferred level, guaranteeing ideal conditions all day long. A comfortable and efficient heating schedule can be created with the thermoregulator, regardless of the time of day—cold morning or warm evening. These systems are a sensible option for improving the insulation and heating of any home because they are also simple to install and maintain.


The forms, capacities, and heating media of the heating elements vary.

The most widely used types are:

Appliances that heat water are the most common use for this design. Because they are made of nichrome and stainless steel, these elements are relatively expensive.

If manufactured with quality, these devices have a service life of over 10,000 hours.


Its design does not differ significantly from the tubular one in terms of the heating element. The stainless steel ribs that are positioned perpendicularly to the main heating element are the only differences. Because of the larger heated surface area of this design, you can increase the heating element’s power.

Electric boilers and other high output applications use the electric heater unit.

By using these heating elements, one can stop worrying about the heating device failing completely. When one heating element burns out, the boiler only experiences a small power loss and keeps working in this condition until the failed heating element can be replaced without running the risk of defrosting the heating system.

Conveniently, this type of heating element can be replaced in minutes without depressurizing the tank, even in a water heater that is filled with liquid. This element is placed into a metal shell that is already in contact with the medium to be heated, much like a cartridge.

Because the heated surface is processed more precisely, these devices have a slightly higher cost.

FET with thermoregulator

Liquids are the primary use for these types of heaters. Thermoregulator not only lets you set the desired temperature, but when it is set to maximum heating, it prevents the liquid from boiling, which removes the risk of an explosion from this kind of heater.

Question of choice

Currently, there are no eternal heating elements. Heating causes the metal to progressively thin at the bending points, which eventually causes the filament to break. Overheating is a common cause of premature heating element failure. This occurs when water heating elements are turned on while the water heater is empty.

The unit can operate for many years without needing to replace the heating element if the proper heating device is chosen.

Cost isn’t always a reliable indicator of what to buy; in several instances, pricey heating elements from reputable brands have only lasted six months.

  1. It is necessary to check the seller"s documents for the goods sold. The warranty that the manufacturer gives on the heating element is also an indirect sign of high quality products. The higher the warranty period of operation, the more reliable the purchased product is.
  2. The correct choice of heating elements can not be made without the selection of the heating element by capacity. which is necessary for heating the liquid. If the heating element will be less powerful than necessary, the water will not be heated to the temperature for which the water heater is designed. When the element consumes high electrical power, there may be an excessive load on the wiring. Therefore, when replacing this element, it is necessary to select a heating element only of the capacity for which the water heater is designed.
  3. When choosing, it is necessary to choose modern devices for disconnecting the supply of electric current. The most advanced in this regard are considered to be thermoregulators, which use electronics to regulate the heating temperature. Devices in which the working element is solid-heat elements, which expand when heated, are outdated and have a limited working life.
  4. The right choice is possible only if the device can freely fit in the tank. otherwise the installation of such a heater will not be successful.
  5. Particular attention should be paid to the choice of the heating element, which will be installed directly into the heating battery. In this case, in addition to the size, an important criterion for selecting the element, are the number of threads on which this device will be installed.
  6. If it is necessary to replace a burned-out TEN. If you go to the store for a new element, you should take the burned one with you and find exactly the same size and marking.

Installation and replacement

You’ll need the following tools to complete installation work:

  • Phillips and slotted screwdriver;
  • pliers;
  • wrenches;

In the event that a replacement heating element is needed, disassemble the failed element before assembling the new one.

If the boiler is connected directly, you must unplug the water heater or disconnect the automatic circuit breakers at the central electric board in order to de-energize it before performing this operation.

The installation process is completed in this order:

  1. It is necessary to wash the tank thoroughly The heating element is removed from the formed limescale and wiped with a rag.
  2. The new heating element is installed in the following way. Make sure that the rubber gasket adheres evenly to the surface of the parts to be connected. All threaded connections must be tightened to the required torque. When the heating element is installed, the electrical wires are connected to it.
  3. Then the bottom cover is installed and the boiler is filled with water. If there are no leaks, the heater can be plugged into the mains.

The plug in the lower portion of the heater is unscrewed, and the heating element is inserted in its place if installing the heating element in the heating battery is required. Subsequently, the heater is connected to the 220 V AC network and the system is filled with liquid.

Heating element unit with thermostat type Ariston (I)

With the help of the integrated thermoregulator, you can program this device to heat a liquid between +20 and +80 degrees Celsius. This device’s working surface is made of copper, which promotes the most effective heat transfer.

RCT 3,0 KW M6

This gadget can be utilized in both homemade water heaters and factory-installed water heating systems. There is a hole in the heating element’s body where a thermoregulator can be installed; these are sold separately.

TENB-9 stainless. 220/380В

Block of water boiler heaters. This device has three fixed elements with a combined capacity of nine kW on one flange. The ability to control the heating power of the liquid is made possible by the heating elements’ consistent insulation from one another. Because the heating element is made of stainless steel, it is shielded from corrosion and can function without issue for up to five years.

Blitz tips

  1. Do not try to repair a burnt-out TEN – it is a useless occupation. If the heating element fails, it must be replaced with a similar device.
  2. The heating element for water must be immersed in the liquid during operation. Otherwise, the device will fail very quickly due to overheating.

Heating elements for heating with thermoregulator

Electric heaters in the form of tubes that are used to heat liquids. Everyone who has ever had to warm a liter of water with electricity knows about these. In rooms without gas equipment, without a centralized city system, or just at the owners’ request, heating elements with thermoregulators are used to provide heat.

Design of the heating element

The conductive part of the TEN design is a metal spiral with high resistance, usually a mixture of nickel and chromium. It is such a parameter as specific resistance that plays a key role in the fundamental operation of the device. According to the laws of physics, the higher the resistance of the metal, the more heat is generated when an electric current flows through the wire. The spiral is placed in a metal tube, which is made of stainless material – carbon steel, copper, etc. TENS in heating batteries are available in three tube diameters – 13 mm – the most common, there are also 10 and 8 mm. The remaining volume of the tube is filled with dielectric, which is often magnesium oxide.

Device and types of thermostat

An apparatus for automating the heating process is the thermoregulator. It is used to control the liquid’s temperature. As per the predetermined parameters, the heater is turned off when the water reaches the desired temperature and turned back on when the temperature "drops." Based on their design, these regulators fall into one of three categories:

  • The rod one is the first and the cheapest option. The principle of operation is based on the action of thermal expansion. The key part is a metal rod placed in the liquid together with a tubular heater. As water is heated, the rod expands and at the moment of the desired temperature and, accordingly, the expansion triggers the thermoregulator, which turns off the power supply. At the same time cooling, the rod decreases in volume and at low degrees again turns on the control device, which brings electricity to the heating coil.

Up until recently, when it became apparent that its performance was not perfect, this type of thermoregulator device was the most widely used. The paradox is that the rod that was previously submerged in the hot liquid starts to shrink dramatically when cold water is added to the heating tank, which includes the heating element for heating in a system that is already heated.

  • The imperfect type of thermostat has been replaced by another type – capillary thermostat. The work is based on the same thermal expansion, only now instead of a rod, the key part is now a capillary tube with a liquid inside, which, when expanding, exerts pressure on the regulator. It solves the problem of false signal when refilling cold water. Such regulators are equipped with the majority of modern models of heaters, while the rod thermostat remains on the market only as a spare part for older models.

  • The third type is definitely a modern solution – the electronic safety thermostat. It includes two sensors: a thermal sensor and a protective sensor. The first one controls the water temperature – it performs the main function. The second monitors the possibility of overheating of the tubular heater. The principle of operation of the sensors is based on the change of active resistance with temperature change. With the help of dielectric abilities of the conductor, such heating elements for heating with a thermoregulator are able to ensure the temperature of water with high accuracy. The electronic device belongs to the class of advanced models and is far from cheap. When choosing this thermostat as a means of controlling a heating system, it is advisable to rely primarily on long-term use. Costs for the equipment are justified, if it is implied long-term operation of the heater. Accuracy and functionality allow you to comfortably control the system and significantly save on energy consumption.

Advantages of heating elements with thermoregulator

The device’s convenience stems from the fact that it combines the functions of heating and control into a single construction. It is fairly simple to replace the heater’s elements without disassembling the other components in the event that the automatic controller breaks.

The least expensive sources of heat are electric heaters with thermoregulators when comparing the prices of various types of heating equipment. All they need is a steady electric signal, and they are simple to install.

One easy way to keep your home at a comfortable temperature is to install thermostats in your electric heating elements. Because of the automatic heat regulation built into these devices, energy consumption can be controlled and the room will always be consistently warm.

The simplicity of installation and use of electric heating elements with thermoregulators is one of their main benefits. These units can frequently be installed quickly and with little difficulty, in contrast to traditional heating systems that may need complicated setups and maintenance. With just a turn of a dial, you can also easily customize your comfort level by changing the temperature to suit your preferences thanks to their user-friendly controls.

The adaptability of electric heating elements with thermostats is an additional advantage. These devices are useful in a range of situations, whether you want to heat one room or several areas of your house. Wherever you need a dependable heating solution, electric heating elements provide it—in living rooms, offices, and workshops alike.

Additionally, compared to conventional heating systems, electric heating elements with thermoregulators frequently have higher energy efficiency. These units contribute to lower energy waste and utility costs by giving you precise control over the temperature and timing of heat output. By using less energy overall, this helps the environment sustainably and is also good for your pocketbook.

To sum up, electric heating elements with integrated thermostats provide a useful and effective way to heat your house. These units offer dependable warmth and assist you in efficiently controlling your energy consumption thanks to their simple installation, intuitive controls, adaptability, and energy-saving features. For maximum efficiency and convenience, think about adding electric heating elements with thermoregulators to your heating system, whether you’re looking to improve comfort in a single room or your entire home.
