About Tankless Water Heaters water heaters

Tankless water heaters (also called on-demand or instantaneous water heaters) heat water as it flows through the unit, eliminating the storage tank entirely. The trade-offs are clear: endless hot water, lower operating cost over a long ownership horizon, and a much smaller footprint — at the cost of higher upfront price and more demanding install requirements (gas line sizing, venting, electrical load). With roughly 1,581 monthly US searches for "tankless water heater," this is one of the most-shopped sub-types in the category.

Tankless splits into two fundamentally different products: gas tankless (condensing or non-condensing) and electric tankless. They serve different households.
