Tankless Water Heater

Definition: A water heating system that heats water directly without the use of a storage tank, also known as an on-demand water heater.

Relevance to energy: Tankless water heaters can be more energy-efficient than traditional storage water heaters because they eliminate standby energy losses associated with storing hot water.

‍

Benefits:

• Can be 24-34% more energy-efficient for homes that use 41 gallons or less of hot water daily
• Provides a continuous supply of hot water
• Generally have a longer lifespan than traditional water heaters

Drawbacks:

• Higher initial cost than traditional water heaters
• May require upgrades to gas line or electrical system
• Can struggle to supply hot water to multiple outlets simultaneously

‍

Statistics: According to the U.S. Department of Energy, tankless water heaters can save a typical family about $100 or more per year on water heating costs compared to traditional storage tank water heaters.
