20 Best Lp Tankless Water Heater (2023 Updated)

A water heater is a device that heats water, typically using natural gas or electricity, and transfers it to a storage tank or directly to fixtures and appliances that use hot water. Tankless water heaters, also called on-demand or instant water heaters, do not have a storage tank.

They heat water as it is needed and do not require a large tank or storage area.
