Water heaters with water supply without pressure

Water supply without pressure

— such water heaters do not imply a direct connection to the water supply and constant operation under high pressure.

The non-pressure principle of operation is found exclusively in tankless models; such devices can be divided into two main categories. The first is separately made heaters that are connected to the water supply through a tap or other similar device; so to supply water to the heater, you must first open the tap. The second option is models that themselves are made in the form of water taps (see "Water heater type"). Anyway, non-pressure devices cannot serve more than one draw-off point.
