The calorific value provided by one kilogram of liquefied gas is approximately 10,000 kilocalories. For example, the calorific value provided by a 15 kg bottle of liquefied gas in a bottle is 150,000 kilocalories. Citizens need to spend 60 yuan to use bottled liquefied gas. ;
According to the calorific value of electricity per kilowatt hour is 860 kcal, to generate 150,000 kcal of heat requires 174.42 kilowatt hours. Calculated at 0.54 yuan/kilowatt hour, a total of 94.19 yuan is needed. .
But the thermal efficiency of electricity is 96%, while that of gas is only 80 to 85%. About 12%. But electricity costs 30% more than liquefied gas.
Conclusion: A comprehensive comparison shows that using electricity costs more than using liquefied gas. There are many types of heating: water, electricity, oil, gas, etc.
Of course, the most common is water. THEprinciple is very simple: use a giant boiler to heat the water, then rely on pressure to circulate the hot water to each home. iron has good thermal conductivity. Once the hot water circulates through the iron heating pipe, it can generate heat and provide heat to our room.
Many residents use the same principle to heat their own homes. They simply use their own stove or small boiler to heat themselves.
Can the water from the water heater be used?
Okay. It is good if the circulation pump in the radiator always contains water. It can be used for a long time and is good for water circulation. It will not produce gas and cause idling but not water at the same time. can also be adjusted using the valve located on the radiator. As its name suggests, the heating circulation pump is ininstalled on the radiator to increase the system pressure and increase the flow of hot water into the radiator, thereby increasing the heat dissipation of the radiator and increasing the internal temperature.
No.
The radiator water is industrial water, not tap water. The water in the boiler and water heater is softened water that has been chemically treated. This type of softened water should not be used for drinking. or for bathing, and it is not for drinking water. In order to prevent scale and rust in the hot sector, a large number of chemicals are added to the water. This water has been in a closed cycle for a long time and generates a large quantity. number of harmful bacteria.
Using this water to wash your feet is very irritating to the skin and can easily cause skin diseases. At the same time, there are certain risks when discharging water without permission. If the radiator is notIf opened and installed correctly, it will cause flooding. Please do not overuse it.

Notes:
1. When testing the pressure of the heating system, pay attention to the presence of leaks caused by loosening, aging and other problems at radiators, pipe joints and valves. Once discovered, notify the dorm teacher immediately and have professionals repair it. After debugging is completed, the valve needs to be repaired and cannot be opened or closed manually.
2. The installation position of the radiator is reasonably designed by the designer. The position is conducive to indoor heating and can ensure relatively balanced air convection and indoor temperature. If the position is changed, it may cause indoor convection. temperature imbalance. Also, oncepipelines and heatingMoving the film can easily cause leakage, which will not only cause economic losses, but also may be harmful to health.
3. Try to maintain a certain amount of heat dissipation space near the radiator in the room. Do not pile debris on or in front of the radiator, otherwise it will affect the heat dissipation effect of the radiator.
