Abstract
This invention relates primarily to an electric heater based tankless water heater, though some aspects may also apply to a natural gas or other fuel based tankless water heater. In particular aspects relating to “smart” communication and coordination of the tankless water heater with other devices, which may be electrically powered or powered by other fuels, may also apply to non-electric flow through fluid heating systems. The subject tankless water heater invention incorporates several aspects relating to energy and construction efficiency which will be detailed further. These include both physical aspects, such as coatings, tubing and heater element design, and electrical aspects, such as power control for individual heater elements, which can make the tankless water heater more compact and more efficient in operation, with reduced instantaneous and long term load on electrical supply systems.
