Thermal head for the radiator: the principle of operation and instructions for the correct installation

An effective heating system is essential for keeping your house warm and comfortable during the winter. The radiator’s thermal head is a crucial part of that system. However, what is it exactly and how does it function? Let’s delve in and examine the basic idea underlying this vital heating apparatus.

Fundamentally, the radiator’s thermal head is an apparatus intended to control the amount of hot water that enters the radiator, thus regulating the room’s temperature. Consider it the intelligence of your radiator, in charge of maintaining the ideal temperature in your house without wasting any energy. It accomplishes this by detecting the room’s ambient temperature and modifying the hot water flow appropriately.

One of the most important steps in making sure your heating system is efficient is installing the thermal head. Even though it might seem like a straightforward task, doing it incorrectly can result in problems like uneven heating, higher energy usage, and even damage to the radiator itself. It’s crucial to carefully follow the recommended installation instructions in order to prevent these issues.

Before you begin installation, make sure to gather all the necessary tools and materials. You"ll need the thermal head itself, along with any adapters or fittings required to attach it to your radiator. Additionally, you"ll want to have a wrench or pair of pliers on hand to tighten any connections securely.

Principle of Operation	Instructions for Installation
The thermal head controls the flow of hot water into the radiator, regulating the room temperature.	1. Turn off the heating system. 2. Remove the old head if present. 3. Attach the new head securely onto the valve. 4. Adjust the settings according to the desired temperature.

Remote control

The distance of distance management is supported by certain thermal head models. Most of the time, this feature just makes using a thermostat more convenient. But, if you have trouble reaching the device’s body, a remote control becomes absolutely necessary.

By what criteria to choose a thermogram?

Numerous manufacturers produce thermoregulating devices.

You must use the following standards as a guide to help you make the best decision:

1. Thermal valve to which the head will be attached. Since the connection can be clip or threaded, you need to pay attention to this moment. If the manufacturer is the same, there will be no problems.
2. Type of threaded connection on the head itself. It can be in the form of a nut with curtains or just round. In the first case, when installing, you need an additional tool to compress the connection. In the second – everything is much easier.
3. The presence of a "skirt". With her, the head looks better, t.To. She closes the working area.
4. Production material. The cheapest thermal drives in a plastic case are. Metallic housing for expensive models.
5. The quality of plastic. Some manufacturers to reduce their costs of their products use the cheapest type of plastic. The strength of the structure suffers from this, and over time, the plastic yellows and loses its aesthetic appearance.
6. Type of working element. The choice will have to be made between liquid, gas, electronic and paraffin.
7. The smoothness of rotation. The handle should rotate smoothly. This is a sign of good quality. All sorts of crackling, creaks and jamming indicate a non -quite high -quality product.
8. Grading and length of the scale. In most models, it is in the range of +5 – +30 ° C. If the division scale is located around the entire perimeter of the head, it can be quickly erased.
9. The presence of an anti -vandal casing. It protects from unauthorized access to settings.
10. Design. Since thermal tacks are mainly located in sight, their appearance and color scheme are important.

It is not required to buy a pre-made set that includes thermal tacks and a thermal valve. These items are available for separate purchase. Not too susceptible to outside heat sources, gas-filled bellows. Undoubtedly, this is a benefit, but the price is far greater than that of liquid bellows.

Automation gives the thermal head a lot of advantages, but it’s not always efficient. Mounting it on cast-iron radiators is absurd. Due to the large mass of the battery, this material has a high degree of thermal inertia. This is where only a manual type of head can function properly.

Thermostatic head principle

• With an increase in temperature, the volume of the bellows increases (mainly due to the expansion of gas or partial evaporation of the working fluid).
• An increase in the volume of the bellows leads to the fact that the spring, the fixing the stem, is released, and the valve gradually blocks the lumen in the pipe.
• This continues until the equilibrium is established inside the device, or until the radiator valve for the thermogram is completely blocked, t.e. the rod will not go to the extreme lower position.

Remote element models operate using a similar scheme. The only distinction is that temperature changes are sensed by either liquid, gas, or electronic distance sensors or by specialized programmable devices like climate control systems. The stem is driven by the information that reaches the thermal cellpan mechanism only then.

Varieties of thermal heads

Three distinct groups of thermal heads can be identified:

• manual;
• electronic;
• Mechanical.

All of them serve the same purpose; the working principle varies only in that regard.

In terms of external performance, manual thermogols are comparable to cranes. The coolant indicator can be turned to the desired setting by rotating the regulator. They are used in place of traditional ball valves. differ in terms of affordability and dependability. Minus: inaccurate settings and user-uncomfortable interface. Frequent use can also cause the regulator to weaken.

Thermostat electronic

The design of mechanical thermal drives is more intricate. In this instance, the temperature is automatically maintained. Its foundation is a segonon cylinder containing a liquid or gaseous agent. The rod moves when the temperature rises above the specified level. The temperature, throughput, and channel section are all lowered to the stated values. Mechanical regulators have the benefit of being easy to use and having accurate settings that automatically adjust the regime. Higher cost is a drawback.

Batteries power electronic models. The microprocessor drives the rod’s movement. Possess greater functionality, such as the ability to control the temperature by the time of day and day of the week, establish the room’s schedule, and turn off the heat when the tenants are not home. These products’ primary drawbacks are their high price and the requirement for battery replacement. Benefits include a wide temperature range, total automation of the process, and ease of use.

Principle of operation

The thermogram’s function with the heating radiator is as follows:

• On the rotary ring the tags are 4 main positions of the regulator. Combining a certain mark on the scale with a tag of the case, the operating mode of the device is set;
• If the air begins to heat up more than the established norm, then through the gaps of the rotary cap, it begins to heat the bell tower with the working substance;
• The heated substance begins to increase in volume, which drives the rod in motion;
• The rod, in turn, through the spool begins to close the passage hole, thereby reducing the flow of the coolant into the battery;
• As a result, the air in the room will begin to cool, and accordingly the sewph with the working fluid will cool;
• the reverse process occurs, and hot water will be supplied to the radiator with the desired intensity.

Devices may vary in terms of adjustment accuracy and control. All mechanical models operate on the same principle, though.

Installation rules

The thermometer needs to be mounted properly. The following connections are advised by manufacturers:

• The case should protect against direct exposure to ultraviolet rays. Otherwise, the accuracy of work is violated.
• Thermal head should be open. You can not put it behind furniture, protective boxes and other obstacles.
• You can not have a device above the heating system. Then the inconsistency of temperatures will be noted.
• The pipeline should not exert pressure on the valve.
• During installation of the remote, the regulator is put on the maximum. Before the installation itself, the movement of the water in the circuit overlaps, and then the liquid is drained.
• Installation is allowed only in parallel to the floor in a horizontal position. You can’t put a thermal tower vertically.

After that, you can start the installation.

Types of structures of thermal heads

A thermogram is displayed on a straight valve in the first picture. Additionally, as seen in the picture below, there are corner thermal chambers.

3. Thermostatic head in a corner for the heating battery regulator

Depending on how the radiators are connected, the thermal canal’s design is chosen based on the pipeline’s design characteristics.

The unique feature of mounting the thermogram on the radiator is that the head should be positioned horizontally for optimal air stream washing and more precise operation of the thermal head.

Thermal tacks can be purchased separately or in combination with radiator valves. In Danfoss’s photothermo-head:

4. The thermostatic head of the radiator (the fraud battery regulator) Danfoss

On this thermogram, a mnemoram is applied in place of a graduation, based on which adjustments are made.

You can install the valves seen in the picture below in place of an automatic thermal canal.

5. The valve that was utilized in place of the heating battery’s regulator

Their distinction is that you can manually change the radiator’s temperature here by turning the flywheel, or valve handle.

On the supply pipe are adjustable valves for thermal drives.

Such simplified valves can be installed at the radiator’s return or exit.

6. The return valve is a simplified valve that replaces the heating battery regulator.

They also feature an attaching size for connecting with a reckoning and a rolled nut for fastening to the radiator. However, upon unscrewing the cover, you will discover a rotating rod in place of the valve. In what ways is it more convenient than a standard valve? The more compact design of this one.

There are numerous radiator valve designs that cannot be taken into consideration, but they all operate on the same principle.

Convectors that are connected to the pipeline from below use the design depicted in the picture below.

7. Convector thermostatic head

The rod that protrudes from the body is visible on the right, where the thermal head or valve is wound.

8. The thermostatic head, which is attached to the convector from below and is a heating battery regulator

The thermostatic head’s considerable hydraulic resistance must be considered when performing the heating system’s hydraulic calculations. It’s possible that the system won’t function as I would like if you entered the typical ball valve in the computations. However, when it comes time for the calculations, I will remind you.

Thermostatic head and battery regulator heating

Rules for installing a control valve

As previously stated, a thermocrane installed horizontally on a radiator yields the highest efficiency.

There are specific guidelines for installing the thermal head, and only strong radiators require adjustment. As a result, this gadget shouldn’t be attached to every battery in the living room. Installing the thermostat on the strongest heating element in the room will result in the highest level of efficiency.

Installing a crane equipped with a thermogram for a radiator on cast-iron heating batteries is not advised as it will not produce the intended outcome. All of this is caused by the inertia of cast iron batteries, which causes a significant delay in adjustment. As a result, installing a thermal head in this situation is meaningless.

Installing the valve on the supply pipe while the battery is being connected to the system is the best course of action. If not, the device must be inserted into the completed system. To achieve this, the heating chain’s component parts are disassembled, and pipes that had previously covered the crane are cut. It is important to read the instructions on how to install a thermogram on a heating radiator because it can be difficult to make the insert into metal pipes.

After the thermostat has been installed, the thermogram needs to be fixed. This procedure, which is as follows, is not very tough:

• On the case of both elements there are appropriate marks that need to be combined.
• To fix the thermal gun, you need to press the device slightly on the device.
• A deaf click will tell about the correct position and installation in place.

Installing anti-vandal thermoregulators is more challenging. This instance requires the use of a 2 mm hexagonal key in order to solve the problem of how to install a thermogram on a radiator.

The following sequence is followed by the work:

• With the help of dowels, the plate is attached to the wall.
• The device housing is fixed on the plate.
• A capillary tube is fixed by clamps on the wall.
• Install a valve with a thermogram for radiators, combining the tags, and press it to the main body.
• Twist a fixing bolt with a hexagonal key.

Selecting the ideal heat-regulating head for a radiator is not a particularly tough decision. Regardless of whether it is in the design stage or has already been presented in the collected form, the primary requirement is that the option must be compatible with the heating system. Furthermore, consideration should be given to the characteristics of each type of thermal controller installation. Experts with decades of experience claim that programmable devices offer the most savings and benefits.

Attention when buying

The efficacy of a radiator handle with a thermostatic head varies. Therefore, you should consult experts before making a purchase. By doing this, errors will be prevented.

It is also important to consider the energy efficiency class when making your selection. There is a Dell symbol on the radiator handle, followed by a letter symbol ranging from a to f. These valves operate and adjust according to the same principle, but the products work well. The Dell-signed radiator thermal head A sign satisfies the highest efficiency class requirements. The least efficient marking heads are Dell F.

Higher efficiency often means slightly higher purchase prices. However, it should be remembered that a more effective thermal head will lead to a more noticeable decrease in the cost of heating the building. The valve has a protruding rod, which, when interacting with the head, closes or opens, reduces or increases the flow of the coolant through the radiator. Incorrectly selected elements can cause improper operation of the device, which will lead to significant discomfort when using. One of the most important selection parameters is the length of the rod or the distance from the valve to the head. It is also necessary to pay attention to the possible type of connection – the liner or valve can be adapted for installing the screwed head with a thread or for installing the installation device with a latch.

In the world of home heating and insulation, understanding the thermal head for radiators is crucial. This small device plays a big role in regulating the temperature of your home, ensuring comfort and efficiency. The thermal head works by sensing the room temperature and adjusting the flow of hot water into the radiator accordingly. Installing it correctly is key to its effectiveness. Begin by turning off the radiator and draining any excess water. Then, carefully attach the thermal head to the valve, making sure it"s snug but not over-tightened. Finally, adjust the settings according to your desired temperature comfort. With the right installation and understanding of its operation, the thermal head can significantly improve the warmth and energy efficiency of your home.

How to choose a thermogolovka on your own

The thermogols on the battery are primarily of three types:

1. manual;
2. mechanical;
3. Electronic.

Manual thermogols

In actuality, a manual heat head is an analog of a ball crane because the user independently adjusts the heat carrier flow level based on information stored in the thermometer or his own senses.

Regulator with manual control

This type’s benefits include low cost and device simplicity. One of the drawbacks is a limited service life, as the internal mechanism weakens and loses tightness with repeated handle rotations.

Heating radiators made of cast iron are typically equipped with manual machinery.

Mechanical thermal drives

Mechanical models that operate on the previously mentioned principle are more common. In such a temperature-sensitive setting, they can:

• liquid. The liquid thermal head has a lower cost and a simpler device, which extends the useful life of the device. But along with this and less speed;
• gas. The production of gas -filled thermal heads is more complicated, which is displayed on the price of equipment.

Make sure the device is pointed toward the room when making the connection. As a result, the temperature regime and the device’s accuracy will both rise.

In order to ensure that equipment can be installed correctly in any circumstance, manufacturers produce:

• with a built -in temperature sensor (drawings above);
• with a remote sensor, which is installed in the most optimal place and is connected to the main device with a capillary tube.

Electronic thermogols

The valve is impacted by the microprocessor found in the most recent electronic thermal head. Batteries are needed for the equipment’s autonomous power.

An autonomous working microprocessor device

Although this equipment is as expensive as it gets, it allows for:

• set a certain temperature regime in the daytime and night, which allows you to achieve comfort in sleep;
• set the temperature on certain days of the week, which is needed, for example, in a country house with temporary residence.

Manufacturers

When selecting a thermal gun, it’s critical to consider both the device type and the manufacturer, as these factors affect the equipment’s dependability and longevity. Experts advise:

• Danish company Danfoss, making thermal drives of all types. The most popular are the devices of the Danfoss RA and RTD series (now partially a series of RTR) – universal equipment for any types of systems;

Danish company’s thermal head

• German companies HEIMEIER, which manufactures equipment under the RTL brand (RTL), Buderus (Buderus), which is part of the Bosch Thermotechnik GmbH and Oventrop (Oventrop) concern;
• Russian-Italian company Valtec (Valtek).

The heat cutter device for the heating radiator

Thermostatic heads, also known as thermostats, are a type of regulatory support for heat supply systems that are used to heat batteries.

In heated rooms, they enable the maintenance of a specific air temperature. Thermal drives, which can be manually or automatically adjusted, are mounted directly on the heating radiators and enable temperature background adjustments indoors.

The purpose and design of the thermogram for heating radiators

The thermostatic head’s primary function is to keep a heated room’s air temperature within predetermined ranges.

The room is equipped with a fixed or dynamic temperature background, depending on the model’s capabilities.

High adjustment accuracy is a defining feature of this class of devices; for models in the average price range, the error does not surpass 1 ° C. By maximizing the circulation of coolant in the heating system, these devices not only help to maintain a comfortable temperature but also contribute to a more economical energy consumption.

Crucial! The average volume of energy saved when using thermal heads varies from 10% to 20% in the limit, depending on the operating mode.

Device

The thermostatic head’s primary structural components are:

• plastic case;
• Sylphone;
• rod, pusher and return spring;
• Stop element;
• sealing elements;
• Fasten elements.

Thermostatic valve

The majority of thermal head models come with valves, whose primary function is to control the radiator’s inlet channel’s diameter. The heating circuit’s direct or corner sections are where thermostatic valves are installed.

Thermostatic thermostatic thermostatic (first photo). The valve device is in charge of controlling how much allowed coolant enters the radiator.

One way to address this issue and greatly increase the device’s efficiency is to remove a thermogram from the valve at the conclusion of the heating season.

Take note! The risk of "biting" into the mobile components of the thermostatic head increases significantly with extended periods of inactivity or operation in a single mode.

Principle of operation

A thermal tunnel sevenphone that is filled with a material that has a high coefficient of thermal expansion—typically wax, toluene, or ethyl acetate—responds to variations in the room’s background temperature. The user adjusts the room’s temperature to their preference.

When this indicator rises, the bellows filler activates a rod that narrows the thermostatic valve canal’s diameter. In line with the predetermined parameters, the radiator’s capacity is decreased and the temperature drops.

Picture 2 shows the radiator thermostatic head’s construction. The device’s components are indicated by the arrows.

The process described above reveals that the filler filler’s volume decreases when the temperature drops below the specified value. The room temperature rises to the appropriate level as a result of improved coolant circulation.

Crucial! When compared to aluminum, steel, and bimetallic radiators, cast iron radiators cool and heat more slowly, making the installation of thermal heads on them inefficient.

Varieties

Several indicators are used to classify thermal heads, including:

• compatibility with thermostatic valves of a certain standard;
• Temperature control method.

Valves compatibility

The RTD-N or RTD-G stands’ valves are compatible with the thermostatic heads.

The selection of a specific standard is contingent upon the attributes of the building’s heating system, specifically the direct feed pipe’s diameter. The valves’ throughput is the primary distinction between these standards.

Increased throughput is a feature of the RTD-G standard valves and their direct equivalents, and they are made to be used for:

• with single -pipe heating systems;
• with two -pipe systems with natural circulation (primarily relevant for private houses);
• In multi -storey buildings.

Take note! Use a bypass when installing thermostatic heads on the heating radiators of single-pipe systems.

Standard RTD-N valves (and their equivalents) are intended for use in:

• buildings equipped with heating systems with forced circulation;
• multi -storey buildings with two -pipe heating systems.

Method of adjustment

Thermostatic heads are conditionally separated into the following groups based on the method of adjustment:

• mechanical devices that allow you to change the temperature manually;
• electronic devices that adjust automatically.

Although mechanical models are less expensive, the adjusting handle eventually wears out from frequent position changes. Furthermore, residents must maintain constant control over these devices.

Electronic thermal drives, in contrast to their mechanical counterparts, independently adjust the room’s temperature in accordance with the predetermined settings. Apart from the evident ease of use, there is a guarantee of reduced risks related to the unmonitored use of thermoregulatory equipment.

Picture 3: An electronic heat head used to heat radiators. The heating device’s temperature is shown on the display.

Programmable electronic thermal drives with timers that let you adjust room temperature based on variables like street temperature and time of day are available for purchase.

Remote control

The distance of distance management is supported by certain thermal head models. Most of the time, this feature just makes using a thermostat more convenient. But, if you have trouble reaching the device’s body, a remote control becomes absolutely necessary.

Placement, installation and setting

The location of the device itself is independent of its type and configuration; both mechanical and electronic thermostats are mounted on the radiator’s coolant supply line. Simultaneously, a continuous airflow surrounding the thermostatic head is a prerequisite for its efficient functioning.

Crucial! It is not acceptable for a thermal head to be installed upright. By installing the device horizontally, or parallel to the floor plane, you can greatly improve its accuracy and eliminate the influence of warm air.

Remote sensor

The majority of thermal heads have integrated temperature sensors; however, these models don’t always work properly.

It is necessary to use the remote sensor that is positioned away from window openings, batteries, and other sources of temperature changes if:

• There is no possibility of ensuring a constant air flow to the device body: the radiator is installed in the wall niche, closed with a curtain or false steam, the distance from the upper face of the radiator to the windowsill is less than 100 mm;
• convection flows affect the accuracy of the integrated sensor;
• Direct sunlight falls on the device case;
• There is no way to eliminate drafts, also adversely affect the accuracy of the indications of the built -in sensor;
• Horizontal installation of thermal tackle is impossible.

Although most of the time using remote sensors is optional, experts concur that this is the only way to get the best indicators of how well thermostatic heads are working.

Installation

Following the manufacturer’s instructions and suggestions, which are included in the operating manual for the thermostatic head that has been installed, exactly is essential to making the right connection.

The following steps should be followed in order to install the thermostat on the heating radiator:

1. Turning off the supply of the coolant, draining the liquid from the radiator.
2. Pipe trimming for the required length, dismantling the old locking reinforcement.
3. Installation of a valve shank in a radiator.
4. Assembly and installation of a binding.
5. Connection of the strapping to the contour, installing the thermostat on the adapter of the installed valve.

Take note! The thermal control regulator should be installed with the maximum value selected. If not, the gadget will function improperly.

Settings

The installed device’s configuration is set based on its kind and features.

For mechanical thermal regulators, all that is required is turning the handle until one of the numbers is displayed alongside a control notch on the casing. If this is done correctly, the handle will then change to a specified value among the values displayed. An electronic thermostatic head’s configuration is determined by its features and a list of functions that it can support.

Temindic temperature sensor

There are various situations where using the remote sensor is required.

• Heating radiators with a thermostat are closed with dense curtains.
• In the immediate vicinity there is an additional source of thermal energy.
• The battery is located under a large windowsill.

Decorative screens are occasionally used to cover heating radiators. This is a situation that is seen in buildings with more interior requirements. In this instance, the inside thermostat only measures the temperature behind the ornamental sheathing. Furthermore, getting access to thermogol is challenging. Installing a thermogram for a heating radiator with a remote sensor solves the issue.

Programmable devices, on the other hand, come in two varieties and have displays for visual control. A control unit may be integrated into some of them or detachable from others. One slight benefit of the second option is that the detachable control unit keeps operating in the same mode. Controlling the heating radiator’s thermal head’s operation is crucial at the same time.

With these models, you can customize the temperature to fit your needs. For instance, you could lower the temperature during the day and raise it at night. Consequently, there are significant savings.

Anti-vandal gadgets are great for homes with young children who like to touch and wiggle things. For this reason, it’s critical to comprehend and be able to install a thermostatic head on a radiator. These kinds of thermal controllers prevent you from accidentally changing the settings. Public buildings, such as kindergartens and hospitals, also use this option.

Advantages of using a thermostat

The benefits of modern thermostats are numerous. Maximum ease of use is one of them. Installing and using these devices is quite simple, and they are very easy to understand. Modern sample devices help create the most comfortable and favorable atmosphere in the rooms. They let you use your resources as wisely as possible and save a great deal of money on heating.

A modification to the valve section underpins the device’s basic operation.

The thermal valve is fastened to the head using a rug nut and a rod. The load from the gas or water, which expands during heating, causes the rod to move. As the pressure inside the head rises, the rod progressively lowers and shuts the valve’s lumen entirely or partially.

The control system determines the following characteristics of the thermoregulator settings for heating pipes:

• The automatic device with a sylphone is characterized by the ability of the rod to return to its original state when the characteristics of the medium are changed;
• The electronic type of regulator is equipped with a thermostat. The temperature level sensor is built into it or mounted on the radiator;
• Mechanical devices, the design of which includes a valve and a crane, are produced without a bellows, have a manual mode of operation – the user must turn the valve handle.

Thermal controllers are installed to save on batteries; with their assistance, the room’s heating costs are lowered by 25%. To achieve maximum efficiency, though, installation of the appropriate device for a given heating system must be done. It’s also important to carefully read the instructions on how to mount the thermogram on the radiator.

Installation sequence

Thermogram’s battery connection diagram

Pipe trimming is the first step in the thermal tack installation process. The task needs to be completed close to the radiator. After that, batteries are screwed into traffic jams, valve tailings are separated, and the outdated locking reinforcement is shown.

Next, the pipes from the sides of the batteries are connected, and the strapping is put together and mounted. The required temperature range is set by turning the lever. Radiator thermostatic heads can be installed at the system’s input or output.

It is imperative to adhere to the manufacturer’s recommendations when selecting the installation location. The installation is essentially between 0.4 and 0.6 meters high. The temperature regime is calibrated for this value. During the upper feed, these requirements are fulfilled. You must change the thermogram to reflect the lower temperature if it is lower.

Features of setting

Preliminary tuning is necessary for the thermogram crane for the radiator to operate properly. Closing the windows and doors and turning on the heating in the room are necessities. The settings are then executed after the thermometer has been positioned at a specific location. The device’s setting diagram looks like this:

• Turn the thermogol to the left until it stops. This will open the flow of the coolant.
• Waiting for an increase in temperature by 5-6 ° C compared to the one that was indoors.
• Turn to the right to the right.
• Waiting for a drop in temperature to initial. Gradual unscrewing the valve. Stop rotation in case of positive noise or heating the radiator.

The most recent position is ideal and correlates with a temperature that is comfortable.

Common errors

To prevent mistakes, the master must pay close attention to every step of the installation process. The head’s vertical position is the most typical issue. Because the thermostat is heated by the incoming air, it causes the room to stop heating up.

Erroneous installation site selection occurs often. A regulator cannot be installed in an area where the ambient temperature significantly deviates from the room’s average. When a thermal head is installed incorrectly, its purpose becomes meaningless.

It’s critical to have efficient heating in your house for both comfort and energy conservation. The radiator’s thermal head is an essential part of this procedure. The performance of your heating system can be greatly improved by correctly installing it and comprehending its working principle.

The way the thermal head functions is by measuring the ambient temperature in the space and modifying the hot water flow into the radiator as necessary. The thermal head expands to let more hot water into the radiator to heat the room when it gets chilly. The thermal head reduces the flow of hot water and keeps the temperature comfortable by closing as the room temperature rises.

The thermal head must be installed correctly in order to operate as intended. To begin, turn off the heating and give the radiator time to cool. Next, unscrew the old thermal head from the valve body to remove it. Make sure there is no debris on the valve body and clean the threads.

Next, screw the new thermal head onto the valve body, being careful not to overtighten but to secure it firmly. Cross-threading the connection can result in leaks, so be careful not to do this. After installing the thermal head, restart the heating system and check that the radiator heats up correctly and that the thermal head reacts to variations in ambient temperature.

Maintaining the thermal heads on your radiators and your heating system as a whole can help guarantee effective operation and reduce energy costs. Check the thermal heads from time to time for wear or damage, and replace them as necessary. You can have a warm and cozy home while using less energy if you know how your heating system operates and take care to install and maintain its components correctly.
