Apollo-V1 2.5KW Diesel Air Heater — Compact, Certified, Cold-Ready
The Apollo-V1 is Vvkb’s compact 2.5KW diesel air heater — built for vans, small RVs, cars, and any space where a full-size unit is overkill. At just 2.6kg, it installs fast and runs quietly, delivering 8,500 BTU of clean, dry heat from a sealed combustion chamber that never mixes exhaust with cabin air.
ated to -40°C and tested at altitudes up to 3,000m, the Apollo-V1 runs on 9V–16V DC and draws from your main diesel tank — no separate fuel source needed. It carries E-mark, CE, RoHS, and FCC certifications, and uses a genuine Japanese Kyocera ceramic glow plug for reliable cold starts every time.
Advanced Electronic Control System
The Apollo-V1 is built around a precision 32-bit electronic control unit that manages combustion, fan speed, and temperature in real time. It supports digital and manual temperature adjustment, wireless ON/OFF control, and onboard system diagnostics — so you stay in control without lifting the hood.
How Does the Apollo-V1 Diesel Heater Work?
Inside the Apollo-V1, a sealed combustion chamber burns diesel in a completely separate loop — exhaust gases exit through a dedicated pipe and never enter the cabin. A 2520 stainless steel burner and A380 die-cast aluminum heat exchanger convert diesel efficiently into hot air, which the blower delivers directly into your living or sleeping space.
The system uses a Japanese Kyocera ceramic glow plug for ignition, a German Heraeus temperature sensor for precision control, and a 32-bit processor to manage combustion and fan speed in real time. Once your target temperature is reached, the heater steps down to a lower output level to maintain it — saving fuel without cycling on and off.
Built with Precision and Quality
The Apollo-V1 is built from components that outlast cheap alternatives. The combustion chamber shell is pressure-cast from A380 aluminum on a 1,000-ton die-casting machine — zero burrs, tight tolerances, and 20% lower operating noise than standard heaters. The 304 stainless steel double-spiral exhaust pipe reduces noise further and resists corrosion over years of use.
All screws use an eco-friendly electroplating process rated for extreme heat. The main power cable is 2mm² cross-section with a 300°C flame-retardant sheath — built to handle hard starts in deep cold, not just normal operating conditions.

Q2: Does the Apollo-V1 have a thermostat?
Yes. Set your target temperature on the controller and the heater automatically adjusts its output to maintain it. When the cabin reaches your set temperature, the unit steps down to a lower power level — it doesn’t cycle on and off, which saves fuel and keeps temperature consistent.
Q3: Can this heater run on gasoline?
No. The Apollo-V1 is a diesel heater only and draws directly from your diesel fuel tank.
Q4: What is the exhaust pipe inner diameter?
The exhaust pipe inner diameter is 24mm. All exhaust components are included in the kit.
Q5: How does the digital temperature controller work?
In AUTO mode, the heater monitors cabin temperature via a built-in sensor. When your set temperature is reached, it automatically slows the fan and reduces combustion output to maintain it. The controller also supports manual mode, where you set the power level directly.
Q6: Can the controller display temperature in Fahrenheit?
Yes. The control panel switches between Celsius and Fahrenheit.
Q7: What is the starting power and operating power?
Start-up power is 90W. Once running, operating power drops to 6W–40W depending on heat level — very efficient for a 12V or 24V battery system.

Installation is straightforward for anyone comfortable with basic vehicle work. For a complete step-by-step walkthrough, see our diesel heater installation guide. If you run into error codes after installation, our diesel heater troubleshooting guide covers every fault code with fixes.You’ll need to mount the unit, run the exhaust and intake pipes, connect to the fuel tank, and wire to the battery.
Q16: Is the hot air from the heater safe to breathe?
Yes. The Apollo-V1 uses a sealed combustion chamber — the combustion process is completely isolated from cabin air. Diesel burns in one loop, exhaust exits through a dedicated pipe outside the vehicle, and the air blown into the cabin is clean filtered air that never contacts combustion gases. The housing plastic is fully FMVSS 302 compliant.
Q17: Do I need to run it at full power when shutting down to clear soot?
No. The Apollo-V1 has an automatic purge cycle built in. When you turn it off, the heater continues running for 3–5 minutes to burn off residual fuel and blow out any soot, then shuts down automatically.
