When buying a water heater you have a few choices, the two main choices being the newer tankless water heaters or the traditional tank type. The installation of tankless water heater is increasing every year. In spite of some inbuilt drawbacks of the storage tank design, there are some good reasons why it is homeowners’ more preferred choice for several years. Installation is simple, as the new unit generally replaces a present storage tank water heater of the same size and fuel. Also, huge production of storage water heaters has made them highly distributed and usually the most available option.
However, the tankless water heater was originally developed by Japanese manufacturers to accommodate smaller available space and high energy costs; as a result it removed many of the longstanding drawbacks of a hot water tank. A tankless heater as the name suggests, stores no water and hot water is produced on-demand only. The unit senses the pressure loss when a hot water tap is opened, and instantly starts flash-heating the water flow. A tankless water heater can be up to 50% more efficient as compared to a storage tank heater because the storage tank is removed which is known to be the cause of high energy consumption and a key source of heat loss.
