FAQs
Do I need an insulation kit?
No. That's kind of the point.
We intentionally chose a very powerful heater for the size of a GFC. In our testing, we've consistently measured a 60-70°F difference between ambient temperature and the inside of the tent without insulation.
Insulation can still make sense if you're camping in genuinely extreme conditions, but it isn't a prerequisite for getting out when it's cold.
How quickly does it heat the camper?
You'll start feeling warm air within minutes. The 4kW heater has considerably more output than is typically required to heat a space this size, allowing it to bring a cold camper up to temperature quickly.
Can I control where the heat goes?
Yes. Our custom HVAC mixing valve lets you bias the airflow upstairs, downstairs, or anywhere in between.
Can I leave it running while I sleep?
Yes, when properly installed and operated according to the supplied instructions. The system includes a carbon monoxide detector, which must be properly installed and operational whenever the heater is being used.
Is it loud?
Not particularly. Quiet operation was one of the reasons we chose Eberspacher. The fuel pump is extremely quiet, with virtually none of the repetitive ticking associated with many inexpensive diesel heaters.
How long does a tank of diesel last?
In our cold-weather use, expect roughly 2-3 nights from the integrated 2.1-gallon tank. Actual consumption varies with temperature, thermostat setting, altitude and operating conditions.
How do I fill it?
Open the camper's side panel and fill the integrated aluminum tank. The tank is vented, and fuel level can be visually checked through the fill opening.
Does it add condensation to the camper?
No. Unlike an unvented propane heater, the system provides dry heat without introducing combustion moisture into the living space. That makes it particularly good for drying wet gear during cold or snowy trips.
What battery do I need?
A secondary 12V battery system is required. We recommend the Comvolt battery and offer a separate integration kit specifically for it. If you're building your own electrical system, the heater includes a Deutsch DTP connection and 10-foot flying lead.
Why does this cost more than a cheap diesel heater?
Because we wanted something we'd actually trust to run all night in a camper with our families.
The GFC system is built around an Eberspacher heater with automatic altitude compensation, exceptionally quiet
operation, proven reliability and access to Eberspacher's global service network. We've then engineered the tank, enclosure, mounting, exhaust, HVAC distribution, electrical harness and camper integration around it.
You install it once.
Then you start looking at the winter forecast differently.
Power
The Diesel Heater Kit requires a secondary 12V battery system with an in-line 15A breaker to operate.
We strongly recommend the Comvolt battery, for which we offer a separate purpose-built integration kit.
Want to build your own power system? That's fine too. The heater harness comes terminated with a Deutsch DTP connector, and we include a 10-foot flying lead for integration into a DIY secondary-battery system.
Typical running draw is approximately 0.5-4.5 amps, with up to 10 amps during startup.
Compatibility
Compatible with V2 Max, V2 Pro, and V2 Classic.
V2 Max uses the camper's existing constant pass-through to deliver heat upstairs. V2 Pro and V2 Classic kits include a half-size floor panel that allows heated air to pass into the tent.
Installation is DIY and typically takes a few hours. Campers without the Diesel Heater Prep Kit will require holes to be cut in the side panel. A complete installation video will walk you through the process.
