Central Storage Type Electric Water Heater

When selecting an electric water heater, you can consider their types and technologies. Here are the options:
1. Instant electric water heater
Provides hot water by turning on the switch, with no preheating required and no storage tank. Its compact size makes it suitable for narrower bathrooms.

2. Central storage electric water heater
Storage capacity ranges from 15 to 38 liters, supporting multiple water supply points. It typically requires 15 to 25 minutes to preheat, while instant models can increase the temperature by 20 degrees(*) in 5 minutes. When used with a low-flow showerhead, it provides 30 minutes of 40-degree hot water.

3. Showerhead storage electric water heater
Storage capacity ranges from 12 to 23 liters and can connect to a switchless showerhead. It mixes hot and cold water to regulate the temperature and provide stable output. Instant models can raise the temperature by 20 degrees (*) in 5 minutes and provide about 30 minutes of 40-degree hot water when used with a low-flow showerhead.
