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 provide haircutsto 10 people 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, savesr about 16% electricity and save up to 4 degrees, saving about 27% electricity.
Calculate how much electricity you can save in a year.
It is very good to use an air-energy water heater. It does not use gas but only electricity to work, so you don't have to worry about accidents such as gas poisoning, fire and explosion. At the same time, air water heaters are also very energy efficient when used. One kilowatt hour of electricity can produce the same amount of hot water that an electric water heater can produce with four kilowatt hours of electricity. 10 kilowatt hours of electricity to burn a ton of hot water (from 15°C to 55°C). The power consumption is only a quarter of that of an ordinary electric water heater, which is very cost-effective and can save dozens of energy. thousands of dollars a year.
