Abstract

A flow-through instantaneous fluid heater system (10) designed to satisfy the need for a heater not limited by being connected to a storage tank and which can be made using a plastic casing (42, 62) incorporates cool-down when out of service and features of venting and simplified flushing and draining. The system incorporates the use of one or more compartments (40, 60) usually assembled in two compartment modules connected in series. Each compartment includes a casing (42, 62) having a hollow cylindrical interior region. An inlet aperture (44) is located at one end of the casing and an outlet aperture (46) is located at the other end of the casing. The lower end of each casing is closed by a removable base (80) and the upper end of the casing is closed by a top plate (85) and a heating element (140, 160). The heating element (140, 160) is positioned axially in the interior region of the compartment. A control system (200) uses temperature comparisons to detect flow through the system to determine whether the heating elements (140, 160) should be activated to maintain the fluid at a stand-by temperature or at an operational temperature.
