See Also Small Storage Units Unvented 'mains pressure' units below 50L capacity are electrically heated and operate at the same mains pressure as the incoming cold water supply (typically 3 bar or so) and therefore provide excellent hot water flow rates.

Simple guide to continuous flow electric water heaters typically used for showers and hand basins Instantaneous inline water heaters are small electrically powered units that heat water 'instantly' as it flows through the product. Instantaneous water heaters are compact, will not run out of hot water and have no stand-by energy losses but have to be wired to the electric consumer unit. The principal draw-back of instantaneous electric water heaters is that the flow rate of hot water is limited by the electrical power rating; single phase units have power ratings of up to 12kW and can provide maximum flow rates up to 6L/min (assuming a temperature increase from the incoming cold supply of 30ºC). Where three phase electricity is available (normally only in commercial premises) instantaneous water heaters are available with power ratings of up to 27kW which can provide flow rates of up to 12L/min.

Electric instant water heaters operate by passing water over a heated electric element. Operation is similar to an electric shower. They do not store hot water but can only supply hot water at modest flow rates determined by the power rating. Single phase units use standard 230V domestic supply.  Electric instant water heaters operate by passing water over a heated electric element. Operation is similar to an electric shower.
