Tankless heating units make use of electrically turned on coils to heat water immediately, as it travels through the tankless system. In a continuous, steady circulation, tankless heating units take in cold water and pump it back out hot, eliminating the consistent keeping and heating of standard systems. The exchange of heat that tankless hot water heating systems operate with is activated when cold water gets in the system.
