How It Works Interior Heating: Specially formulated antifreeze is heated by the burner in the main heating unit (left). A circulation pump pushes the hot antifreeze to each heat exchanger using a closed-loop system of tubing. When a zone calls for heat, the exchanger fan comes on, pushing hot air. Cooled antifreeze returns to the burner plenum for reheating. HOT WATER: In the hot-water system (right), potable water is heated through an isolated loop, requiring no tank. The water runs through the coil where it is heated and flows, on demand, to the RV’s faucets.
