The thermostat plays a very important role in the heating system. It helps to control and control the temperature in such a way as to ensure optimal thermal comfort in the selected room. The most famous example of a thermostat is the thermostatic head, placed directly next to the radiator. What is a bimetallic thermostat, how does it work, what are its advantages?

How does a bimetallic thermostat work?
The principle of operation of a bimetallic thermostat uses the thermal expansion properties of materials. Two metal plates are mounted inside the thermostat, and each of them has different thermal expansion parameters. These strips are connected to each other, most often tied or welded. The mechanism of action is that under the influence of temperature, one metal begins to deform, bending the strip of the other metal connected to it.
The plate of metal that begins to expand more quickly under the influence of temperature bends towards the other metal used. This mechanism is most often used to control the opening or closing of an electrical circuit.
The principle of operation based on the mechanical properties of metals means that devices based on a bimetallic thermostat are characterized by high measurement precision, and the range of temperature control can be really wide. This feature makes this thermostat model perfect for devices and systems that require quick adjustment of operation to changing thermal parameters.
The thermostat is additionally equipped with a special fuse. This is the so-called thermal switch, which is responsible for disconnecting the circuit in the event of excessive temperature increase.
Advantages and applications of a bimetallic thermostat
The bimetallic thermostat solution is commonly used in many electrical devices that are used every day in homes. Examples include: oven, iron, radiators, heaters or refrigerators. They are also perfect, for example, in fire protection systems, where they help protect selected electrical components against overheating. In addition to heating systems, bimetallic thermostats are also used in cooling systems.
The most frequently mentioned advantages include simple construction and operating principle. Thanks to this, they are elements that work in all conditions. Power failure is no problem and the bimetal thermostat is highly reliable. This is a big advantage compared to models that are powered by electricity. Additionally, they can operate without faults for a long time. They also do not require any special maintenance. Analyzing the advantages in the context of construction, it is worth noting that all components are permanently connected to each other, so the risk of damage is negligible, and the thermostat has a long service life.
Specialists use bimetallic thermostats also because they are universal solutions. They can be successfully used in radiators, stoves, air conditioners and refrigerators. The low failure rate makes it perfect both in home conditions, where the loads are insignificant, and in industrial conditions, where a potential failure could lead to serious consequences and faults.
The bimetallic thermostat is easy to install, configuration and operation are not complicated, and additionally ensures maximum safety in all conditions.
Bimetal thermostats in the Onninen wholesaler
The idea of using bimetallic thermostats to regulate temperature has been used for a long time, while the development of technology and increasing knowledge allow the method to be constantly improved. Thanks to this, modern solutions are even more effective and effectively prevent overheating of any equipment or system.
Onninen's offer includes modern solutions, such as the KAN-therm bimetallic room thermostat 230V/24V , prepared by SYSTEM Kan-Therm. A solution dedicated to two-wire installations. In this variant, the bimetal is normally closed inside an aesthetically pleasing box. The housing is tight and durable, so you don't have to worry about damaging it. There is a knob on its outer part that allows you to easily and conveniently set the optimal temperature. The range is from 5 to 30 degrees Celsius. The entire device is small in size, so the sensor does not negatively affect the aesthetics of the interior. The thermal switch has all the necessary approvals and certificates.
