Abstract (en)
[origin: WO2004072562A2] An improved pre-heating, contiguous in-line water heater is described. The in-line water heater utilizes a passive heating means to passively heat at least a portion of the input water received by the in-line water heater. The result is a more cost efficient water heater. The in-line water heater is integrated with a means for control to receive input from at least one sensor and to regulate the operation of the in-line water heater.
