Frequently Asked Questions

What's a diesel heater?

A diesel heater (also known as an air heater or forced air diesel heater) burns diesel fuel in a combustion chamber that is completely separate from the ambient air. It produces dry hot air that is blown through ducts into your space (converted van, RV, truck, roof tent). It is ideal for winter camping in Canada, extended off-grid stays, and extreme temperatures.

Why choose diesel heating over propane heating?

Dry heat: Diesel heaters produce very dry air (no condensation or added humidity), unlike unvented propane or Buddy heaters, which generate humidity (condensation on walls, especially in poorly ventilated roof tents or vans).

Increased safety: No open flame or combustion in the passenger compartment → no risk of CO poisoning if installed correctly (isolated combustion + gas evacuation to the outside). Always add a CO detector for added peace of mind.

Effective in extreme cold: Works perfectly down to -40°C / -46°C (especially Espar), diesel does not freeze like propane can. Economical: Less fuel consumption (often < 0.5 L/h), diesel available everywhere in Canada.
Main disadvantage: Always requires 12V electricity (approximately 20–40 W in continuous operation, peak of 100–150 W at start-up for 2 min). With an auxiliary/solar battery, it is perfect for off-grid use.

Are diesel heaters legal in Canada?

Yes, they comply with federal safety and emissions standards (CSA/UL for Espar). Professional installation is recommended for provincial compliance and to avoid any risk.

For which vehicles/setups are they ideal?

Converted vans, RVs, trucks, trailers.

Roof top tents: Dry heat that quickly dries the tent (ideal after rain/snow), works all night without condensation.

Ground camping tents or extended camping.
Power: 2 kW (small spaces/compact vans) to 8 kW (large vans, spacious roof top tents, extreme climates).

What is the fuel and electricity consumption?

Fuel: Very low, often < 0.5 L/h (e.g., 0.2–0.28 L/h at low speed for 2 kW; up to 0.54 L/h max for powerful models).

Electricity: 20–40 W on average once started (peak 100–150 W at start-up). Compatible with 12V vehicle battery, solar power, or auxiliary battery.

Are they quiet?

Yes, very quiet (especially Espar < 50 dB). Perfect for sleeping at night. Chinese models (Vevor) are a little noisier in terms of the pump, but are still acceptable.

What about security?

Separate combustion chamber + overheating protection + low CO emissions. No contact between flame and interior air → clean, smoke-free air in the passenger compartment.

Which models do you recommend?

Espar (Eberspächer): German premium brand, ultra-reliable, automatic altitude compensation, very quiet, 2-year warranty. Ideal for extreme Canadian winters.
Airtronic D2 (diesel, ~2.2 kW): Perfect for small vans/roof tents.
Airtronic D4 (diesel, ~4 kW): For larger spaces. Gasoline versions (B2/B4) if your vehicle runs on gasoline. Affordable models (Vevor, etc.): 2–8 kW, Bluetooth on several, portable or fixed, excellent value for money for beginners.

BEST SELLER: 8 kW Bluetooth Roof Top Tent Diesel Heater: Simplified setup, app control, off-grid autonomy.

Why Espar vs. Chinese models?

Espar: Better durability, CSA/UL certifications, less vibration, parts available in Canada, stable performance at altitude/off-road. Fewer returns. Chinese: Less expensive, reliable for occasional use, but more frequent maintenance.

How to install a diesel heater?

Possible as a DIY project with a complete kit (safe location under the vehicle or inside, fuel pump, hot air ducts, external exhaust).

Recommended: Professional installation for safety (to avoid leaks, CO, etc.).

What are the costs and installation locations?

$250 for professional installation (on the South Shore of Montreal, Sainte-Julie, QC – 1551 Rue Coulombe).

With integrated tank (non-vehicle): Included in the service.

Turnaround time and expertise: We install Espar, Vevor, and compatible systems on vans, trucks, and overland trucks.

Why add a dedicated tank?

For extended autonomy (long trips, isolated areas).

  • Capacity: 5 to 20 liters.
  • Robust: Corrosion-resistant, shock-resistant.
  • Easy to use: Ergonomic handles, compatible with most diesel heaters.
    Alternative: Pump connected directly to the vehicle's tank (simpler, less complex).

How to choose the right power?

2 kW: Compact vans, well-insulated roof tents.

4–8 kW: Larger vans, climates of -30°C and worse, poorly insulated spaces.
