room thermostat, types and placement it has been modified: 2021-05-13 di Benedict Flowers

The room thermostat is a device capable of detecting the temperature of the room in which it is positioned and of managing the ignition of the boiler by comparing the detected temperature with that requested by the user.

The room thermostat is a fundamental component of the heating system through which the degree of thermal comfort and at the same time the amount of energy consumed can be managed. If used well, a good thermostat can lead to energy savings and consequently economic savings.

The task that a thermostat has to perform might seem very simple, apparently it would only be a matter of switching off or turning on the boiler, in reality it is not quite like that. Over the years the boilers have evolved in the direction of one greater efficiency, the reduction of consumption and environmental impact, with a strong reduction of gas production greenhouse. This research process also involved the room thermostat, to which more advanced functions are required.

The simplest type of thermostat is the mechanical thermostat where the element sensitive to the variation of temperature is a fluid or a metal sheet. In this type generally the only possible functionality is the on / off one. It is the same sensitive material that, deforming as the temperature changes, opens or closes the electrical circuit that ignites the boiler.

A more evolved type is the electronic thermostat which uses the variation of some electrical parameters as the temperature varies as a working principle. Generally this type of thermostats, in addition to the on / off function, can switch summer or winter operation, manage multiple daily temperature levels, for example night and day, have an anti-freeze function, useful in the case of little-used rooms.

latest development is that of the thermostat modulating which adds to the typical functions of the electronic thermostat the ability to detect how quickly the required room temperature is reached and, based on this data, to regulate the operating temperature of the system. In this way, the number of starts / stops is reduced and greater comfort is obtained (the room temperature is more stable).

programmable thermostat

In all types of thermostats, it is possible to have one programming function in the time of the ambient temperature, in this case one speaks of programmable thermostat.

With the chronothermostat you can program the room temperature according to the time and days of the week, obtaining better comfort than a classic thermostat. For example, you can program the heating to switch on a few hours before waking up, or a lowering of the room temperature for the hours of the day that we know we spend outside the home, and then raise it again before our return.

The chronothermostat can also be of various types: mechanical, analogue, digital, or of the connected type, the choice of the suitable solution depends very much on the user's lifestyle and on the way in which the house in which it is installed is used.

thermostats with daily programming, are particularly suitable for apartments and homes that are not subject to excessive variations between one day and another. Those a weekly programminginstead, they allow you to set a different temperature for each day of the week, so as to reduce consumption while having a comfortable temperature when necessary.

Il room thermostat connected it is certainly the most flexible, it combines the advantages of programming with the possibility of intervening remotely at any time, ensuring the right room temperature even in unforeseen situations. In addition to the well-being management, further advanced functions are added that allow you to know the operating status of the boiler in real time, including the management of anomalies. On the other hand, it requires a certain familiarity with technology.

Where to place the thermostat?

The position inside the house is very important for the correct functioning of the room thermostat. Having to detect a datum that is representative of the temperature of the entire home, the thermostat must be positioned in the room of the house where most of the activities take place, such as the living room. or in an environment that has an average temperature compared to all the others, in a central room of the house.

If the thermostat were placed in the coldest part of the house, the other rooms would be too hot. Conversely, if it were placed in the hottest place, the other rooms would be cold.

The room thermostat can be placed on a piece of furniture or a shelf, or fixed to a wall at an average height of 150 cm from the ground. It must be protected from drafts from heat sources and, if installed on the wall, it must not be placed on a wall in contact with an unheated area or in contact with the outside.

Another alternative could be to install the thermostat in the coldest place in the house, then installing in the other rooms the thermostatic valves which, automatically, exclude the radiators in the rooms that have reached the desired temperature.
