This listing is for a used in‑line fluid heater (Calix) removed from an electric Smart Car. This heater is Swedish‑made and well‑known for quality and durability. It was used less than 5,000 miles and includes the power plug with at least 4″ of wiring and the OEM mounting bracket.
This fluid heater is perfect for EV coolant heating loops, battery thermal conditioning, cabin heating integration, or custom liquid‑cooled systems. OEM fluid heaters add efficient, controlled heat directly into a coolant circuit, reducing reliance on resistive heat or heat pumps alone.
