Can I use a smart plug for water heater?

Short answer: Usually not recommended unless the plug is specifically rated for that load.

Explanation

Water heaters are high-power appliances. Use only a device rated for the heater's current and wiring requirement. For fixed water heaters, a smart breaker or contactor setup is usually more appropriate than a plug-in smart plug.
