A 2KW heater is enough for a single cab. An 8KW heater is what you need when you're heating a motorhome, a boat cabin, a bus, or a large sleeper truck without running the engine all night.
The Fredlox Direct 12V 8KW Diesel Parking Heater delivers serious heat output with remote control and LCD switch operation, so you can set and monitor your cabin temperature without getting up. The built-in muffler keeps exhaust noise low during overnight operation, and the unit runs off your existing diesel fuel supply — no separate propane tank, no inverter, no extra hardware. Whether you're parked overnight in a semi, living aboard a boat, or wintering in an RV, this heater keeps your space at temperature without touching the engine.
Why You'll Love It
