Do tankless water heaters heat as well as tank-based systems?
Tankless water heaters are designed to provide instant hot water and can heat water as efficiently and effectively as tank-based systems. However, you may need to install more than one tankless water heater in larger homes or units with multiple bathrooms to ensure hot water is readily available.
