Maradyne 4000 12V Auxiliary Heater

This 12-volt auxiliary heater delivers 13,200 BtuH of heating capacity while drawing 6 amps at 30 watts. The housing is constructed from glass-filled nylon for durability. Mounting hardware is included with the unit. It is designed for automotive and similar 12V DC applications.

Suits vehicles needing supplemental cabin heat

Buyers who want a primary heating system for a large space should look elsewhere. This unit provides auxiliary output only and is not intended to replace a factory HVAC system. It also requires a 12V DC power source capable of supplying the rated current.

Verify your 12V circuit can supply 6 amps

Confirm the available mounting area accommodates the overall dimensions of 9 7/8 inches high by 7 5/16 inches long by 7 1/4 inches wide. Ensure the mounting surface is compatible with the included hardware. Check that wiring and fuse ratings match the heater's current draw.
