ABSTRACT:
A heater (10) for installation on a potable water tank (12). The heater (10) comprises a blanket (14) including an electrical resistance heating element (16) and a connection pad (18) for electrically connecting the heating element (16) to lead lines (20) to an aircraft power source (22). The water tank (12) is typically positioned under the cabin floor or other locations on an aircraft which are susceptible to cold temperatures, moisture invasion, and pressure drops/rises caused by changing altitudes. The heater (10) maintains the tank (12) at an acceptable temperature range and prevents freezing of the water.
