The special device for heating boilers called “best programmable thermostat” was developed and introduced in order to provide even heating and rational electric energy consumption. The working principle of different models is very similar, but there are some important differences. Thus, the heating signal can come to the heat carrier from the sensors measuring the temperature indoors or outdoors. In this article, we’ll discuss the characteristics of the popular thermostats for heating boilers and find out how to choose them.
Usually, the work modes of heating boilers are regulated by the sensors measuring temperature of the heat carrying agent. Actually, it’s not always convenient, as the regulator with the specified temperature of the fluid, signals the boiler to turn on if the heat carrying agent has got cold. However, the indoor temperature, changing at different times of the year, is not taken into account. That is, in spring the batteries will work just like in winter, while the thermostat, measuring the temperature in a heated room, will allow you to turn the boiler on and off with the dependent data.
The thermostat has an in-built heat monitor, located in the room, where you want to measure the average temperature. You must do it so that the battery heat doesn’t impact the sensor. After getting an information about the room temperature, the regulator gives signals to the heating boiler.
The device measures the temperature and, as necessary, turns off the heating system. When the temperature decreases to the fixed thermostat readings, the boiler turns on again.
You should define the place of installation and characteristics of the heating boiler sensors already in the system design stage, and pre-estimate the parameters of heat supply. Then, based on this data, choose the separate parts of the system.
The thermostat for radiator is not an exception. But apart from the technical characteristics, you should consider its performance:
- precise handling. This quality allows you to understand what changes in the temperature of heat carrying agent will activate the device;
- automation of thermostat. It allows you to understand how often you’ll have to manually adjust the settings to normalize the functioning of the system;
- additional mode. Almost every model can be configured to the cyclical work (daily or weekly) – advanced settings allow working in strict compliance with the specified settings;
- features of mounting. You should check if it’s possible to mount the thermostat in any position, as some models are installed strictly in one position.
