How does a boiler thermostat work?
A boiler is basically a specially designed water heater – which distributes heat through hot water, while systems like a central furnace distribute heat through warm air. Water is heated in a special chamber of the boiler (which is usually powered by gas or fuel oil) and is then distributed to different rooms of the home via radiators or other heat distribution systems installed. A boiler thermostat helps in controlling the boiler operation, thus maintaining a proper set temperature inside the home.

What is a thermostat?
A Thermostat is basically a temperature sensor with a switch and a memory (to set the desired temperature). Based on the set temperature, a thermostat switches the HVAC system (heating/cooling system of your home) “ ON ” or “ OFF ” to regulate the temperature inside the room in which the thermostat is installed.
What is mechanical thermostat?
Mechanical thermostats are provided with coiled metal that expands or contracts according to the temperature. Well, this is certainly not the best way to control temperature even though it has been sufficient for most of the people over the years. Still, these thermostats result in incorrect temperature readings and it has been noted that they keep the temperatures higher than the set point. With everyone concerned about energy savings, it is important to remember that whenever your room temperature goes up by 1 degree Celsius, you end up using up to 10% more energy! Therefore, this thermostat is not a choice for those cautious energy savers.
What is the difference between a mechanical thermostat and a non-programmable thermostat?
Non programmable electronic thermostats function similar to the mechanical thermostats; the major difference is the metal coil in the mechanical thermostat is replaced by an electric temperature sensor in this device . A tiny microprocessor that is set inside this thermostat sends ‘start’ or ‘stop’ commands to the heating or cooling system based on the reading it takes and the chosen temperature setting. In fact they are more accurate than the mechanical alternatives, but, you have to set the favorite temperature manually and make necessary changes during the course of the day manually.
