ABSTRACT:
A fluid heater apparatus supplies heat to wash fluid via a flow path in a thermally conductive body. A heat source is disposed in the thermally conductive body for imparting heat to the body. Fluid in a flow path in the thermal body enveloping the heat source absorbs heat from the body. A fluid expansion member is fixed to the mass over the open ends of the fluid flow path in the thermal body. The fluid expansion member is formed of a compressible foam material having shape memory. The fluid expansion member is sealingly joinable by fasteners to the thermal body through bores formed in the peripheral edge of the member.
