How Tankless Water Heaters Work:

1. Cold Water Inlet: When hot water is needed, cold water flows into the tankless unit through the inlet pipe.

2. Heat Exchanger: Inside the tankless unit, a heat exchanger heats the cold water. Gas-powered tankless water heaters use burners to generate the heat, while electric tankless heaters use electric elements.

3. Hot Water Outlet: The now-heated water exits the tankless unit and travels to the tap or appliance where hot water is required.

4. No Storage Tank: Unlike traditional water heaters with storage tanks, tankless water heaters do not store pre-heated water. They only heat water as it is needed, which eliminates standby heat loss.

Advantages of Tankless Water Heaters:

1. Energy Efficiency: Tankless water heaters are more energy-efficient than traditional tank heaters because they only heat water when it is needed. There is no energy wasted keeping a large volume of water hot in a storage tank.

2. Space Savings: Tankless units are compact and can be mounted on walls, saving valuable floor space compared to traditional water heaters with tanks.

3. Continuous Hot Water: Since tankless water heaters heat water on demand, they can provide a continuous supply of hot water as long as the demand does not exceed the unit’s capacity.

4. Long Lifespan: Tankless water heaters often have a longer lifespan than traditional tank heaters. With proper maintenance, they can last for 20 years or more.

5. Reduced Risk of Water Damage: Since tankless units don’t store large volumes of water, there is a reduced risk of water damage from leaks or ruptures associated with storage tank failures.
