Danfoss thermoregulator: operating principle, instruction, feedback

In many countries, up to 40% of energy resources go to the needs of ventilation and heating of buildings. This is several times more than in the advanced European states.

Need to use

The issue of energy saving is particularly acute, it is important against the backdrop of a constant increase in energy prices. One of the devices that allows to save thermal energy is a thermostat for radiators, its installation reduces the heat consumption by 20%. To do this, the user must correctly choose the design for the heating system, and also perform the installation, you can learn about this by reading below.

Principle of operation

The Danfoss temperature regulator is designed to maintain a constant indoor temperature. For the first time such devices began to be used in 1943. This company is the market leader in the production and sale of such units. Structurally, the devices have two main elements, namely a thermal head and a valve, which are connected by a locking mechanism. The purpose of the thermal head is to determine the temperature of the environment in order to regulate the effect on the actuator, the valve acts as the latter. It is designed to cover the flow of water that enters the radiator. This method of regulation is called quantitative, since the device can affect the water flow that passes into the battery. There is another method, which is called qualitative, with its help the water temperature changes in the system. This is done by means of a temperature regulator, namely a mixing unit. This element must be located in a heating station or boiler room. The Danfoss thermoregulator has a bellows inside which is filled with a heat-sensitive medium. It can be gas or liquid. The last type of bellows is easier to manufacture, but does not show the same speed as gas analogs, so the latter have become so widespread. When the temperature of the air rises, the substance that is in the enclosed space acquires a more impressive volume, the bellows, stretching, affects the valve stem. The latter move down the cone, which is designed to reduce the cross-section. This makes it possible to effectively reduce water consumption. When the air temperature decreases, this process proceeds in the reverse order, and the volume of the heat carrier increases to the optimum limit, and the Danfoss temperature regulator works.

Customer Reviews

Depending on which type of heating system is used, as well as what is the installation technology, thermal heads and valves can be used to control water flow in different combinations. If it is a single-pipe system, a valve should be used, which is characterized by increased throughput and low hydraulic resistance. According to users, the same recommendation can be used in the case of a two-tube gravity system, where the water circulates naturally and is not affected by forced motivation. If you decide to choose a Danfoss temperature controller, you can also install it on a two-pipe system, which is equipped with a circulation pump. At the same time, according to the feedback, the valve should have the ability to adjust the capacity. This adjustment is quite simple, and there is no need to use a special tool for this. After you decide which valve to use, you should determine the type of thermal head.

Additional consumer recommendations

If you are interested in Danfoss - the thermostat, the installation instructions will be presented below - you can purchase it at an affordable price. When determining the type of thermal head, you should know that it is offered for sale in some varieties. Thus, a thermoelement can be inside. Among other things, the temperature sensor can be remote. Sometimes the regulator is external. Devices are also programmable, in this case they are electronic. You can choose a vandal-proof thermal head. According to users who chose a controller with an internal sensor, this device should be installed only if it is possible to position it horizontally. Then the air in the room will flow freely to the body of the device.

For reference

After you purchased the Danfoss radiator thermostat, it is worthwhile to become more familiar with the features of its installation. Thus, it is absolutely unacceptable to install it on the radiator in an upright position. In this case, the heat flow will constantly rise upward, and the increased temperatures from the supply pipeline and the housing will affect the bellows. In the end, you will come across the fact that the device will not work correctly.

Customer feedback on the choice of thermostat

Home masters especially stress that in some cases it is not possible to install the device horizontally. Then it is recommended to buy a remote temperature sensor, which comes complete with a capillary tube. The length of the device is 2 meters. At this distance from the battery, it is recommended that you place the device on the wall. Buyers emphasize that it is not always impossible to install the regulator horizontally indicating the need to purchase a remote sensor. There may be other objective reasons for this. The Danfoss thermoregulator, the principle of operation of which was described above, can not be installed behind thick curtains, in this case, of course, the best solution will be to purchase a remote sensor. Among other things, such a need arises when a source of heat is located near the thermal head or hot water pipes pass. You can resort to such a decision, and when the radiator is under a wide enough window sill. In this case, the thermocouple can get into the draft zone. Buyers say that if at least one of the above conditions is met, then it is best to purchase a remote sensor.

Installation Instructions

The Danfoss thermoregulator, reviewed in this article, must be installed using a specific technology. As the first recommendation is the elimination of mounting the thermal head on the heater within sight. Regulators should be exposed to batteries whose total power is 50 percent or more of all that are in the same room. Thus, when there are two heaters in the room, the thermostat must be on the same battery, whose power is more impressive. If you are interested in Danfoss - the thermostat, the setting of which is simple enough, it can be purchased and installed by you. The first part of the device, in the role of which the valve acts, should be installed on the supply pipe. If it is necessary to cut into the already assembled system, the feeder must be dismantled. These works may involve some difficulties if the connection is made using steel pipes. The master will have to stock up with a tool to cut the material.

Conclusion

Danfoss is quite a popular company on the market of the corresponding goods today. The thermostat (how to adjust it, indicated in the instructions) must be installed on the radiator. The thermal head is then mounted without using an additional tool. It's very simple to do at home, in addition, you can save on purchasing supplies.
