Whats in the hot box？
*Product images feature the Combusto V2-V3.
We are currently on V3.1, with small changes in design layout.
This unit is intended for quick, ground-level run-and-gun use. For safety reasons, do not permanently bolt the heater to your racks or operate your vehicle with the heater fixed in place. Always use a quick-release style mounting solution instead.
Our customers have successfully tested two mounting methods:
-Diesel Heater Exterior Hangers (Affordable)
-Croc Hinge Recovery Bracket(Pricey)
Before your overland trip:
Production & Lead Time : As of winter 2025, we’ve been unable to maintain extra inventory, so all heaters are now turn-key builds — made to order, tested, and shipped fresh. We are experiencing longer lead times due to demand.
Combusto Updates：
We’re making two design changes to the Combusto heater.
If you have any custom design requests, feel free to reach out when ordering your turn-key build — the layout can be customized to better suit your setup, whether for a ground tent or a rooftop tent.
1. Intake Ducting May Be Removed
We’ll be removing the clamps and brown ducting connector between the intake outlet and the core unit cover, leaving them disconnected by default during shipping. The connector will still be included inside the case and can be optionally installed if desired.
After collecting sufficient feedback, we’ll decide whether to retain or permanently remove this ducting outlet in future versions. Originally, the outlet was designed to cycle warm air from a tent back into the heater, but since the 5 kW unit already provides strong output even in subzero conditions, this feature may be better suited for the 2 kW version moving forward.

2. Power / LCD Panel Port Relocation / Deletion
We’ve relocated the power port and LCD panel connectors to the intake side of the unit. This change follows our updated design approach:
• Hot components remain on the exhaust side
• Cool components are positioned on the intake side
We’re also evaluating whether to retain or remove the external LCD port, keeping the control panel mounted internally for a cleaner and durable setup — especially since the remote control can fully operate the system on its own.
These updates are designed to improve user convenience, enhance service accessibility, and extend component longevity. We welcome your ideas and are always happy to make your design requests a reality.
