Tankless water heater

— tankless water heaters provide heating of water directly in the course of its passage through the device. Thus, heated water comes immediately — there is no need to wait until it heats up; and the amount of water supplied, in fact, is not limited by anything. At the same time, efficient operation requires high heating power, which creates certain difficulties: tankless gas heaters are difficult to install, and electric heaters, due to high consumption, require connection to the mains according to special rules, or even three-phase power.
