It must be instant heating.
The small size of the hair salon means that the flow of customers is not high, but customers will come at any time and your hot water should be ready accordingly. If you are using a large keg, you need to make sure the machine is always on for heating and insulation, which uses a lot of energy. The instant heat type is heated on the go without any electricity consumption and its energy consumption is much lower than that of a large barrel.
It is therefore recommended to choose an instantaneous water heater, but choose one of good quality. A friend used a tankless water heater from a "major household brand" and was serviced often, but in very good condition. attitude.

For example, compare the 50 liter barrel water heater and the instantaneous water heater:
1. The hair salon will cut the hair of 10 peoplennes tomorrow and will use hot water for 20 people. 20 liters of water are used, the total consumption of the water heater per day is 400 liters and the water temperature is 38 degrees.
2. The theoretical energy consumption data of the two water heaters is 10.7 degrees (the basic water temperature is 15 degrees)
3. Electric heat conversion efficiency and utilization rate; of bucket type is 70%-80%, therefore the actual power consumption is 13.4-15.3 degrees
4. Good instantaneous electric heating conversion efficiency and utilization rate is above 95%; German nickel-gold heater. Therefore, the actual power consumption is 11.3 degrees;
Conclusion: Using an instantaneous water heater (good heating technology) saves at least 2.1 degrees per day compared to a bucket type water heater, saves approximately16% electricity and save up to 4 degrees, saving about 27% electricity.

1. Use energy-saving lamps, turn off the lights and unplug the socket.
2. Use less air conditioning and open more windows.
3. Try to do your work during the day to save energy.
4. Use “high end” microwave ovens to save energy.
5. Wash the rice in advance and soak for 10 minutes, saving about 10%.of electricity.
6. The amount of electricity used by a water heater to keep it hot for a day is less than the amount of electricity used to heat a box of cold water to the same temperature.
7. Adjust the TV screen to medium brightness, which can save power and protect eyesight.
8. Clean the vacuum cleaner in time,Otherwise, dust collection efficiency will be reduced and power consumption will increase.
9. Turning on the strong gear of the washing machine saves more energy than turning on the weak gear and can also extend the life of the machine.
10. Turn off power to electrical appliances such as water dispensers when not in use.
