Tankless water heaters have several advantages over conventional storage type water heaters that store a large volume of water in a tank.
One advantage is that since the tankless unit does not have a tank, there is no continuous heat loss from the large volume of stored hot water. Typically tankless heaters do not have standing pilot lights like tank type units, saving even more energy.
Another advantage is that you have virtually unlimited hot water, you will never run out.
