Thermostats for radiators: types, principle of operation and

In this article we will look at what are the external thermostats for radiators. These small devices allow you to secure the work of boiler equipment, thereby prolonging its operational life.

But let's get everything in order.

Technical description

Operation of the heating system is associated with numerous risks associated with overheating of the coolant in the circuit or the boiler equipment itself. This can lead to emergencies of varying severity, ranging from the rupture of the battery and ending with the occurrence of a fire in the house.

Radiator thermostats can prevent any dangers associated with possible overloads in the heating pipeline and have the following characteristics:

Merits

• Economical use of electrical energy or gas. A thermostatic valve for the radiator eliminates the use of fuel at idle, which significantly reduces utility bills
• Improving the fire safety of your home. The possibility of fire and explosion of heating equipment due to overloads is excluded.
• Excellent performance even in extreme conditions, including freezing temperatures of the environment.

Tip: if you need to install a thermostat on a heating radiator located on the street, then buy a special non-freezing device that will easily transfer our harsh winters.

• Long operational life.

Tip: when you purchase a thermostatic valve, make sure that he has a quality certificate that makes the device eligible for warranty service for at least one year.

• Possibility of zonal temperature control. You can set your own microclimate in each room.
• Simple installation instructions. To perform the installation does not require any specialized skills.

• Affordable price. In comparison with the fact that the valves of radiator thermostats allow to save on the use of energy carriers and prevent the occurrence of emergency situations that can be dangerous for the lives of residents, their cost is negligible.

Design

Mechanical thermostat for radiator has the following structure:

The principle of operation of the thermostat for a heating radiator is as follows:

1. The thermostatic element has in its structure a bellows filled with a sensitive substance that reacts to temperature changes in the medium in contact with it.
2. In case of excessive heating, the bellows changes its shape, stretching and moving the rod, which in this case puts pressure on the valve connected to it.
3. The valve changes its position, thereby limiting the flow of coolant.
4. In the case of a decrease in temperature, the process is carried out in reverse order, and the system continues to operate in normal mode.

Tip: after the coolant has been stopped as a result of the thermostat triggering, it is recommended to check its integrity. The fact is that if it is deformed under the influence of a critical temperature, then with the next similar situation it will not work, and the heating equipment will remain unprotected.

Kinds

Before you choose a thermostat for a cast-iron radiator, steel or bimetal, you need to know the parameters of the entire system. It is desirable that this task was performed by specialists with special measuring equipment.

When all the necessary parameters are known, you can choose between the following thermostat options:

1. Room As a rule, these models have an electronic filling and use free air flow to measure the temperature, so you should not block their furniture or even curtains. They are not directly used, but they perfectly complement the complex protection of the heating system, especially when it comes to electric heaters.

1. Thermostatic valves. They do not control the boiler, but they effectively reduce the flow of coolant passing through the battery on which they are installed. It is advisable to install such devices in places with the lowest pressure, which will lead to substantial savings. Can be inline or overhead.

1. Remote Zone Zone Controllers. Such units are able to control the temperature of the air using infrared rays in a room or a specific area. In case of violation of the mode, they give a signal to the boiler or radiator regulator, which causes the system to stop working. Excellent function paired with thermostatic valves.
2. Cylinder thermostat. This is a programmable liquid controller, which is simply necessary when using double-circuit heating boilers, at the outlet of which the coolant reaches very high temperatures.

1. Smart thermostats. These devices are similar to the previous ones, only control is carried out from a special command unit, turning off the boiler operation until the system is fully normalized.

Installation

Before you install the thermostat on the radiator, you should purchase all the necessary connection kit:

Next, perform the following steps:

Conclusion

Thermostats installed on radiators do an excellent job with protecting the entire heating system. Thanks to their work, you will not only keep expensive boiler equipment intact, but also protect your home from fire. Among the many types of thermostats, it is easy to choose the best models for your home or apartment, and their installation is easy to do on your own.
