Qmark Electric baseboard heaters and Cadet Electric baseboard heaters contain a sheathed electric heating element completely immersed in a heat transfer liquid and sealed in a heater-length copper tube. This maximizes the volume of heat storage fluid to prolong the thermal constant of the entire heater.
