In various embodiments, the invention provides a system for heating a liquid,
such as, for example, water, comprising a plurality of liquid heaters, the inlets
and outlets of which are respectively connected in a parallel flow relationship
by respective manifolds, and configured to provide liquid having a temperature
of greater than about 90 degrees Fahrenheit at a flow rate of greater than about
10 gallons per minute. In various embodiments, the present invention provides an
electric tankless liquid heater system capable of delivering hot liquids, and in
particular water, at even higher flow rates and or temperatures, including, but
not limited to, flow rates greater than about: (1) 12 gpm; (2) 18 gpm; (3) 20 gpm;
and (5) 20 gpm; and/or temperatures of greater than about: (1) 100 F.; (2)
120 F.; (3) 140 F.; and (4) 180 F.
