An electric immersion heater for use in conjunction with tanks made by different manufacturers. The tanks are typically cylindrical and include an annular mounting flange at the upper open end provided with a specific arrangement of mounting apertures receiving fasteners connecting the heater mounting flange to the tank.

The immersion heater is provided with a mounting flange having an arrangement of mounting apertures which permits the heater to be used with tanks with mounting flanges having different mounting aperture arrangements without the necessity of adaptors or special flange arrangements. The immersion heater is selectively mountable to a tank flange having a specific set of circular mounting apertures disposed at angular intervals on a common pitch circle diameter, or another tank flange having a different set of circular mounting apertures disposed at different angular intervals on the…
