Tankless electric water heaters may not be recommended in some cases for the following reasons:
More power:Instantaneous electric water heaters typically require higher power to heat water quickly, which can lead to high instantaneous currents and a certain amount of pressure on the load on the grid, especially in areas where power is unstable** and can trigger power fluctuations.
Limit hot water flow:Instantaneous electric water heaters are usually suitable for small flow and small capacity hot water needs, if a large flow of hot water is required, such as multiple faucets used at the same time, it may lead to insufficient hot water ** and affect the use experience.
Higher installation costs:The installation of tankless electric water heaters is relatively complex, requires professional electricians to operate, and requires a large enough power supply. This can increase the cost and difficulty of installation.
High maintenance costs:Due to the complexity of instantaneous electric water heaters, the cost of repairs and replacement parts is high in the event of a problem.
High requirements for the power grid:In some areas where electricity is unstable, instantaneous electric water heaters may be more susceptible to power fluctuations and have higher demands on the grid.
Environmental Considerations:Since instantaneous electric water heaters need to provide a large amount of hot water in a short period of time, there may be a problem of energy waste, especially when some countries or regions promote energy conservation and environmental protection, and may not meet the relevant policies and requirements.
Although instantaneous electric water heaters may have the above problems in some scenarios, they are still a viable option for small flow and small capacity hot water demand, or when there are high requirements for instantaneous heating. The choice of which type of water heater to choose should be weighed against specific needs, usage scenarios, and local power conditions.
