Abstract
Disclosed are systems and devices for controlling the amount of water passing through a heat exchanger and the amount of water that by-passes the heater without passing through the heat exchanger. In some embodiments, the system includes a by-pass valve assembly having means for sensing a time-varying characteristic of fluid adjacent the inlet, means for sensing a time-varying characteristic of fluid adjacent the outlet, and a valve that alters the amount of fluid by-passing the fluid heater in response to differences in the time-varying characteristic of fluid adjacent the inlet and fluid adjacent the outlet.
