A temperature maintenance heater assembly 10 for maintaining the temperature of a heated fluid circulating through piping of a bath, including a pipe section 70, base plate 40, control device assembly 30, base plate cover 80, and a heating element 20. The pipe section has an outer wall 72, an inlet
A temperature maintenance heater assembly 10 for maintaining the temperature of a heated fluid circulating through piping of a bath, including a pipe section 70, base plate 40, control device assembly 30, base plate cover 80, and a heating element 20. The pipe section has an outer wall 72, an inlet 74, and an outlet 76. The control device assembly 30 has a first and second pressure switch 32A and 32B, wherein each of the first and second pressure switches have first and second electrical terminals 34A, 36A, 34B and 36B, pressure sensors 38A and 38B, and switch mechanisms 39A and 39B activated by the pressure sensor 38A and 38B. The base plate 40 has an upper surface 42 and a lower surface 52, wherein the control device assembly 30 is attached to the upper surface 42 of the base plate 40, and the base plate 40 is attached to the outer wall 72 of the pipe section 70. The base plate cover 80 is removably attached to the base plate 40, and wherein the cover 80 encloses the control device assembly 30. The heating element 20 has a first and second electrical contact 22A and 22B, wherein the heating element 20 is housed mainly in the pipe section 70, the electrical contacts 22A and 22B pass through the pipe section outer wall 72 and pass from the lower base plate surface 52 to the upper base plate surface 42, and at least one of the electrical contacts 22 is conductively connected to the control device assembly 30.
