Functions of a Tankless Water HeaterA tankless water heater provides you and your household with hot water on demand without having to use any storage tanks. When you are ready to use hot water, you turn on the tank and cold water is released into a pipe that goes through the tankless water heater. Electricity or gas, whichever type of heater you have, works to heat the water and your hot water is quickly delivered. Even a tankless water heater eliminates the wait for a full storage tank of hot water, the flowing rate of hot water from a tankless water heater can be limited as well. A tankless water heater gives you the ability to access around 3 to 4 gallons of hot water on demand every minute. Typically, tankless water heaters that operate by gas give more hot water per minute than a tankless water heater that operates by electricity. However, this does not meant that one tankless water heater, rather gas or electrical, is able to provide hot water for a heavily occupied home at one time. In other words, if you live in a household where hot water is running constantly at the same time, like one person is in the shower and the other is washing dishes both using hot water, it is recommended to have more than one water heater.
