Different Types of Electric Water Heater
Electric water heaters are key for consistent, on-demand hot water in homes. They come in two main types: storage and instant (tankless).
Electric Storage Water Heaters
Electric storage water heaters fill a tank with water and heat it using electrical elements. They are great for homes with scheduled high water use. These systems heat water to a set temperature and store it until needed. When you open a hot tap, the hot water from the tank flows out.
Instant (Tankless) Electric Water Heater
Instant electric water heater, also called tankless, heat water as it flows through the device. No water is stored in a tank. When you turn on the tap, cold water travels over heated coils and warms up instantly. This type is perfect for homes with less space or sporadic hot water needs. These systems are energy efficient as they only heat water on demand.
How Electric Water Heater Operate
Understanding how electric water heater function is key to appreciating their benefits. Let’s look at the two main types and their operation processes.
The Process in Electric Storage Units
Electric storage water heaters include a tank where water is heated and stored. Cold water enters the tank and settles at the bottom. Electrical elements in the tank then heat the water to a preset temperature. The heated water rises to the top of the tank, ready for use. When you turn on the tap, this hot water flows out. A thermostat controls the temperature, and a pressure relief valve maintains tank safety.
The Mechanism of Instant Electric Water Heater
Instant electric water heater, or tankless systems, work differently. They do not store hot water. Instead, they heat water directly as it flows through the unit. When you activate a hot tap, cold water travels through a heat exchanger within the unit. Electrical elements instantly heat the water to the desired temperature. This means hot water is always available on demand, without the need to store it.
Benefits of Electric Water Heater
Electric water heater offer several benefits to homeowners. They provide a consistent supply of hot water. This ensures comfort and everyday convenience.
