Find out what the numbers on your radiator thermostat mean and how to ensure the perfect temperature in your home without increasing your bills.
How does a coolant thermostat work?
The majority of heaters in homes display numbers from 0 to 5 on the control knobs. A scale indicating specific temperatures may be misleading because it will be different from the temperature obtained in the room.
Understanding how a thermostat works is not complicated. The thermostatic valve reacts to changes in the ambient temperature. The thermostat is mounted on the radiator’s water supply tube. Its function is to regulate the water pressure and open and close the valve according to the temperature.
To test the operation of the thermostat, you can try this mode in the fall or winter.
How is a coolant thermostat built?
The coolant thermostat has a simple structure. In its head is a blower filled with a substance that contracts or expands in response to temperature changes. The materials used in this can be liquid, gaseous or wax. It shrinks when the room temperature drops, letting in hot water, and similarly expands when the temperature rises too high and prevents water from getting into the coolant.
What do the numbers on the coolant thermostat mean?
Radiator thermostat heads usually have a scale from 0 to 5, and each number has a different function. If you want to effectively manage the temperature of your room, it is helpful to know what the numbers on your coolant thermostat mean:
Snowflake or 0: It does not mean that the thermal valve is completely closed. This mode prevents water from freezing in the radiators and maintains the temperature between 6 and 8 degrees Celsius.
number 1 : The temperature is regulated around 12-13 degrees Celsius. The situation is directed to spaces such as the staircase, garage and any other room where clothes are worn.
Number 2: This is a coolant thermostat setting, producing heat at 15-16 ° C. Manufacturers recommend using it in the bedroom because it maintains the ideal temperature for sleep.
Number 3: This mode is suitable for the kitchen, living room and other living areas. The temperature regulated by the coolant thermostat here is 18-20 ° C.
number 4: This setting results in a temperature of 22 to 24 °C and is commonly used in children’s bedrooms and bathrooms.
Number 5: This mode is not recommended for daily use as it maintains the house temperature at 25-28°C
Why is the coolant thermostat not set to “5”?
Setting the coolant thermostat to maximum temperature is not the best solution for heating a room. The only thing we can achieve in this way is dry air and unpleasant heat in the room. In addition to increasing the energy bill.
Which number would you choose on the coolant thermostat?
The best solution is to gradually change the position on the heater. In the thermostatic valve, when the temperature changes to 16 degrees, that is, from number 2 to number 3. This will give an ambient temperature of 20 ° C in the room.
Therefore, the optimal setting for the coolant thermostat is the dedicated mode No. 3, which will maintain the room temperature at 20 ° C.
If you want to save on heating bills, you can set the minimum temperature in the room during the day and increase it only in the evening. At night, it is worth setting the thermostat on the radiator to number 2, which will ensure optimal conditions for sleep. (The temperature is not ideal for sleeping)
If you leave the house for a long time, switch the thermostat to number 1 or snowflake so that you do not use up heat energy unnecessarily.
How to ventilate so as not to pay more for heating?
Venting into the coolant thermostat should be done wisely so as not to increase your home heating bills. During the heating season, it is better to ventilate briefly but often. If you want to keep the windows open for a long time, set the thermostat on the radiator in the shape of a snowflake so that it doesn’t generate heat that will escape out the window anyway and actually increase your energy bill.
It is therefore advisable to adjust your coolant thermostat correctly if you want to avoid unpleasant surprises in your bills at the end of the month.
