  • the instant application claims the benefit of and priority to U.S. patent application Ser. No. 10/365,072, filed Feb. 12, 2003, U.S. provisional application Nos. 60/526,352 and 60/526,333, both filed on Dec. 2, 2003.
  • the instant disclosure generally concerns water heaters. Specifically, the instant disclosure concerns pre-heating, in-line water heaters.
  • In-line water heaters are designed to heat a continuous supply of input water only when hot water is demanded by a user. This is in contrast to typical storage tank water heaters which keep, on the average, 30-70 gallons of water heated and ready for use 24 hours a day. Opening a hot water faucet triggers one or more heating units (typically, either electric or gas) to heat the water as it flows through the in-line water heater. The water takes a circuitous path through tubing in the in-line water heater so the heating units of the in-line heater have an opportunity to heat the water sufficiently. With in-line water heaters, there is never a shortage of hot water since there is never a tank to deplete. In addition, since there is no tank to heat continuously, there is a significant energy savings.
