Solar water heater is a device used to absorb and convert solar energy, and there is no special note about this device in Feng Shui.
Moreover, the solar water heater is located above the bedroom, which can also prevent the bedroom from being baked at high temperature in summer, which is beneficial and harmless.
However, in the process of using solar water heaters, special attention should be paid to timely water supply and timely maintenance of solar water heaters to prevent water heaters from bursting and leaking.
