1. What is a tankless water heater?

Currently large number of North Americans use a storage tank water heater to tend to their hot water needs. Such a heater keeps water hot 24 hours a day, even while you're at work or sleeping, thus causing unnecessary wastage of power. A Tankless Water Heater, on the other hand, does not store hot water but heats the water as and when you use it.
