Tankless water heaters, also known as on-demand water heaters or instantaneous water heaters, are innovative appliances designed to provide hot water as needed WITHOUT the use of a storage tank. Unlike traditional water heaters, which continuously heat and store water in a large tank, tankless water heaters heat water only when there is a demand for it, such as when a faucet is turned on or an appliance requiring hot water is activated.

Water heaters are indispensable appliances in multifamily buildings, ensuring a consistent hot water supply for various domestic needs. The choice of water heater type profoundly impacts efficiency, utility costs, and resident satisfaction. This article delves into the nuances of different water heater options to empower building owners with the knowledge to make informed decisions.
