Abstract:
A method for decreasing scale buildup on an electrical heating element in a heater tank, the heater tank having a fluid inlet pipe, the method comprising the steps of:extending the fluid inlet pipe proximate the electrical heating element;providing a plurality of apertures in the inlet pipe pointing towards and along the length of the heating element;directing jets of fluid from the apertures to the surface of the heating element with sufficient force to dislodge at least a portion of the scale that may have accumulated on the electrical heating element; andlocating a deflector adjacent to the electrical heating element and positioned opposite said apertures in the extended fluid inlet pipe for deflecting at least a portion of the jets of fluid that pass the heating element back towards the heating element, thereby increasing turbulence in the heater tank proximate to the heating element.
