Introduction: As an indispensable electrical appliance in daily life, water heater has always attracted much attention for its power consumption.
In order to save energy and reduce emissions, many consumers have questions about the way to use water heaters: is it always on to save electricity or to turn on when it is in use to save electricity? This article will answer this question in detail from both theoretical and practical aspects.
1. The working principle of the water heater is normally open and re-opened when in use
1. Water heater always open: It means that the water heater is always on and provides hot water to users at any time.
2. Re-opening the water heater when it is in use: It means turning off the water heater before using the hot water and turning it on when it needs to be used.
Second, the main factors of water heater power consumption
1. Water heater power: The higher the power, the greater the power consumption.
2. Water heater insulation effect: the better the insulation effect, the lower the power consumption.
3. Frequency of use: The higher the frequency of use, the greater the power consumption.
4. Ambient temperature: The lower the ambient temperature, the greater the power consumption.
3. Comparison of power consumption of water heaters when they are always open and re-opened when used
1. Theoretical Analysis:
(1) The water heater is always open: The water heater is always in working condition and needs to be continuously heated and insulated, so the power consumption is large.
(2) The water heater is turned on when it is in use: the water heater is not heated when it is off, and it is only turned on when hot water is needed, and the power consumption is relatively small.
2. Practical Verification:
According to the experimental data of relevant institutions in the mainland, the power consumption of the water heater when it is always on is about 1.5 times that of the re-on.
However, in the actual use process, this value will be affected by many factors, such as usage habits, ambient temperature, etc.
Fourth, how to choose the use of water heaters
1. From the perspective of energy saving: the method of re-opening when used is more energy-saving, which is conducive to energy conservation and emission reduction.
2. Consider the usage habits:
(1) If the water heater at home is not used frequently, just turn it on one hour before taking a bath and turn it off again after taking a bath, which can save a lot of electricity bills.
(2) If the water heater at home is often used, but it is only used for bathing, it is recommended to turn it on again when you use it.
(3) If the family members use it frequently, it is recommended to take a bath with water and reduce the number of switches to avoid damaging the circuit.
3. Water Heater Temperature and Capacity Selection:
(1) Set the temperature of the water heater according to the season and your own habits, generally about 42 degrees in summer and 46 degrees in winter.
(2) Choose the capacity of the water heater according to the amount of water used by your home, and after the last person washes it, the water will run out, which can also save electricity bills.
5. Summary
To sum up, the water heater is relatively more energy-efficient when it is used and then turned on.
However, in actual use, consumers also need to choose the appropriate heating method according to their own needs and usage habits.
At the same time, reasonable setting of water heater temperature and capacity can also reduce energy consumption to a certain extent and achieve the goal of energy conservation and emission reduction.
