What Is a Tank Water Heater?

Tank water heater is a big tank that serves the purpose of heating water for bathing, washing dishes, or doing laundry. Hence easy design and simple performance, these heaters still make it popular for households. Here is how they work:

How a Tank Water Heater Works

Delivery: In turn, opening a hot-water tap draws hot water through the top of the tank while allowing cold water to flow into it to refill the space emptied.

What Is a Tankless Water Heater?

How a Tankless Water Heater Works

On-Demand Heating: A gas burner or electric element instantly heats the water as it goes through.
Continuous Supply: Hot water is conveniently provided directly to your tap without the need to store it.
