What limitations do tankless water heaters have?
A. Because this type of water heater heats the water as you use it, the volume of hot water that it can deliver is directly correlated to the amount of its energy input. The bigger the burners or heating elements in the unit, the higher the volume of hot water that it can deliver. Today tankless water heaters come in various sizes to suit most homes’ needs. Even if you need to be operating multiple showers at once, tankless water heaters can keep up.
