Because that is its job! A thermostat is a device that measures the temperature of a given space or volume, and turns heating / cooling devices on and off accordingly. The thermostat in your house is designed to turn the heating off when the house is warm and turn it on when the house is cold. The thermostat in your car turns the radiator fan on when the oil / water temperature increases to a level that could be damaging to the engine (if you are stuck in traffic for example)
the temperature mat should be around 76 c unless if it is new to the house, that temperature should be 76c.
In a normal house furnace a fan forces air through an exchanger. This usually consists of some pipes or tubes. A fire on the outside of the tubes heats the air inside the tubes as it passes. The force of the fan also pushes the air along duct work and the warmed air comes out floor vents or regesters. The suction of the fan draws air from through out the house through the larger wall mounted cold air vents. The air passes through a filter and then into the fan where it is then sent to the exchanger. The thermostat that you set for the desired temperature measures the room temperature. When the temperature falls below the set point the thermostat sends a signal to the furnace to start the fan and then turn on the flame. When the temperature at the thermostat rises above set point the signal to the furnace is shut down, the fire goes out and the fan stops.
Absolutely. A thermostat in your house maintains the temperature you put it on at a constant level. It sends a small electrical signal to the heater unit (Oil or Gas) turning it on and off, this is done by two methods. The old way was a coil that would move a mercury filled glass attached to it, to open and close the contacts that would make or break the circuit. The better ones are electronically controlled and do, in theory, exactly the same thing. Think of it as an on and off switch to the heater unit.
House temperature in Celsius (centigrade) is 20°C which is 68°F.
20 degrees Celsius is 68 degrees Fahrenheit; but I like it cooler than that in the Winter.
It is 31 degrees higher.
The temperature in the house is that of the temperature outside
The answer depends on the thermostat setting as well as the kind of heating system that you have.
23ºF = -5.0ºC
The thermostat tries to control the heating and cooling in you home to maintain a comfortable or energy efficient temperature.
it can go up or down
The temperature will vary as not all parts of the house would be burning at the same rate. Also, gusting winds will affect the temperature too.
On the vents closest to the main unit it should read around the same temperature that the thermostat is set to after its been running and then as the venting increases the temperature should be less, between 2 to 10 degrees different depending on how well the ducting is in the attic........
