Definition
The household tankless water heater market refers to the global industry involved in the manufacturing, distribution, and installation of on-demand, instantaneous water heating systems designed exclusively for residential use. Unlike traditional storage water heaters that rely on insulated tanks to store and reheat water, tankless water heaters operate by heating water only when needed, using gas burners or electric heating elements. This eliminates the energy losses associated with stored hot water and enhances the efficiency of home water-heating systems.
