(1) The price is high.
② High power and high line requirements. The working power of instant water heater is relatively large. Usually, in order to better realize the effect of instant heating, that is, the power of the instant heating water heater is usually above 6KW, so there will be greater requirements for the power cord when it is used. Usually, this kind of power can't be borne by the current of ordinary household 15A.
③ The installation requirements are relatively high. When installing an instant water heater, it is required that the pressure at the water inlet should not be too high. Some instant water heaters also require the user's home electricity meter to be 20A, and at the same time, they need independent lines. Therefore, from the installation conditions, this is also a limiting factor affecting the use of instant water heaters.

Extended data
principle of operation
That is, the hot water boiler converts electric energy into heat energy by using a heater with strong thermal conductivity in a high-power state, and the heat energy transfers the heat to the water, and the water is heated quickly by using strong heat.
The working principle of the instant drinking machine is that the control module controls the water pump to work and continuously injects cold water into the heater, and at the same time, the control module is connected with the heating power supply of the heater, so that the cold water flows through the heater and is heated at the same time, and the hot water flows out through the pipeline.
