VEVOR CY-29 8kW 12-24V Diesel Air Heater: features, specs and who it suits

The VEVOR CY-29 is a diesel-fuelled parking heater that runs from a 12V or 24V vehicle electrical system. It is intended to warm small enclosed spaces such as an RV, camper, truck cab, boat cabin or trailer, using fuel from its own tank rather than the vehicle's engine heat.

How a diesel air heater works

A diesel air heater burns a small amount of fuel in a sealed combustion chamber and passes cabin air across a heat exchanger. The combustion gases leave through a separate exhaust pipe, so the heated air itself does not mix with exhaust. The heater is powered by the vehicle battery for the fan, fuel pump and igniter. VEVOR gives the supply voltage as DC 12V to 24V.

Heating area and ignition

VEVOR says the unit suits spaces of about 161 to 215 sq ft. It uses a ceramic igniter, which the brand says gives quick starts in cold weather. The heater is rated at 8 kW, but the listing's coverage figure is the practical guide to the size of space it suits.

Fuel use and tank

The listing quotes fuel consumption of 0.18 to 0.36 L/h, which VEVOR translates to about 1 gallon per night. The tank holds 5 L (1.3 gal), and VEVOR gives combustion efficiency as 90% or higher. A precision low-noise fuel pump delivers the fuel. A fuel gauge helps you see when to refill, which VEVOR links to reducing the risk of dry burning. Actual consumption depends on the heat setting and conditions.

Controls and display

The heater comes with a remote control with a stated range of 98 ft, so you can pre-heat a vehicle from outside. An LCD screen allows temperature adjustment between 32 and 104°F. The listing also mentions a square colour digital display and voice announcement.

Protective features

VEVOR lists a heat-insulated exhaust pipe shield to help avoid burns, and a leak-proof fuel cap meant to reduce spills on rough roads. These are the brand's descriptions; the manual covers the exhaust routing, fuel line and mounting requirements.

Altitude, size and weight

The heater is listed as working effectively at altitudes under 9843 ft. It measures about 16.1 x 10.0 x 12.4 inches and weighs 17.7 lb. VEVOR describes it as compact and easy to install.

Who it suits

It suits people who use an RV, camper van, truck or boat in cold weather and want a heat source independent of the engine and any mains hookup. It's a fixed installation, not a portable indoor heater.

What to check before you buy

• Voltage: confirm whether your vehicle runs on 12V or 24V and that the heater suits it.
• Space: compare your cabin with the 161 to 215 sq ft range.
• Installation: this is a combustion appliance with fuel and exhaust lines. Follow the manual and local codes and regulations, and use a qualified installer if unsure.
• Exhaust and ventilation: the exhaust must be routed outside as the manual specifies.
• Fuel and upkeep: check what fuel it takes and what maintenance and replacement parts the manual lists.
• Altitude: check that your travels stay within the 9843 ft limit.
