VEVOR 8KW Diesel Air Heater: features, specs and who it suits

The VEVOR 8KW diesel heater is an all-in-one portable air heater that burns diesel fuel to warm a van, truck, RV, tent or garage. A diesel air heater draws fuel from its own tank, burns it in a sealed chamber and blows the warm air into the space, so it works without using the vehicle's engine. Here is what VEVOR's specs mean, and what to check before installing one.

Heating output and speed

VEVOR rates the heater at 8KW and says it heats spaces of 108 to 161 square feet (about 10 to 15 square metres). It says the heater reaches up to 210°F in 5 minutes and makes a vehicle interior comfortable in 10 minutes. These are the brand's figures, and actual results depend on insulation, outside temperature and the size of the space. Larger or poorly insulated areas will take longer.

Fuel use and tank

VEVOR lists fuel use of 0.04 to 0.1 gallons per hour, with efficiency over 90 percent. The 1.1-gallon tank is meant to support all-night heating without refilling. The lower figure applies to low settings and the higher to maximum output. A quiet fuel pump is part of the design, and the brand describes the heater as low-noise. Diesel heaters typically make some pump ticking and fan noise, particularly when starting.

Power options

The heater runs on 12V or 24V DC, which covers most cars, vans, trucks and RVs, and on a 110V household outlet. The all-in-one design keeps the parts in one portable unit. VEVOR says it can operate below 9,842 feet (about 3,000 metres) of elevation. Diesel heaters generally burn less cleanly at high altitude, so check the manual for any limits.

Controls

You adjust temperature from 46.4 to 96.8°F using either the LCD screen or the remote control, which works from up to 98 feet (about 30 metres) away. Being able to preheat before you drive makes a cold vehicle more comfortable and reduces the load on the engine at start-up, according to VEVOR.

Protection features

VEVOR lists several protection features: a carbon monoxide alarm, an exhaust pipe heat sleeve, a sealed fuel cap, overheat shutoff at 536°F or above, and reverse polarity and overvoltage protection. Those features are the brand's own description.

Any fuel-burning heater needs careful installation. Exhaust must be routed outside the space and sealed correctly, and fresh air must be available. Follow the manual and local codes, fit a working carbon monoxide alarm, and never run a fuel-burning heater in a sealed room.

Size and weight

The listing gives the dimensions as 16.9 x 11.8 x 10.0 inches (about 43 x 30 x 25 cm) and a weight of 17.2 lb (about 7.8 kg). It's portable enough to move between uses, but think about where the unit, exhaust pipe and fuel line will go.

Who it suits

VEVOR lists compatibility with RVs, trucks, SUVs, vans, tents and garages. It suits people who spend nights in a vehicle in cold weather, or who want a heat source in a workshop. Anyone considering it should be comfortable with an installation involving fuel and exhaust.

What to check before you buy

• Space size: compare the heated area with your vehicle or room.
• Power source: check whether you will run it on 12V, 24V or 110V.
• Installation: plan the exhaust, air intake and fuel supply as the manual describes.
• Fuel: use the fuel the manual specifies, and keep it safely stowed.
• Noise: think about where the unit sits relative to where you sleep.
• Upkeep: check the manual for cleaning and parts replacement.
