ABSTRACT:
An electrical heater for fluid including a generally tubular housing have a wall portion made of a titanium material, and an elongated electrical heating element having electrical connectors on opposite ends thereof extending through the wall portion. The electrical heating element has an outer sheath made of a titanium material, and an inner sheath made of a stainless steel material. The electrical heating element has an electrical resistance line disposed within the inner sheath and connected to the electrical connectors at opposite ends thereof. The electrical heating element includes a dielectric material disposed within the inner sheath around the electrical resistance line to facilitate heat transfer from the electrical resistance line to the inner sheath.
