VEVOR CY5004 Horizontal 8KW Diesel Heater: features, specs and uses

The VEVOR CY5004 is a horizontal, all-in-one 8kW diesel air heater for vehicles and garages. Its low, wide shape suits spots where height is limited, and it works from 12V or 24V DC. This page explains the specs and what to check before choosing one.

What "all in one" and "horizontal" mean

An all-in-one diesel heater combines the burner, fan, fuel pump and controller in a single case, with a tank and exhaust added as the manual describes. Horizontal refers to the layout: the unit is about 16.5 x 10 x 12.2 inches and weighs 18.6 lb, so it is lower than a tall upright design. That can help in a van locker, a trailer box or a garage shelf, but always confirm clearances in the manual.

Heating and efficiency

VEVOR lists the power as 8kW, with combustion efficiency of 90% or higher. Construction is a cast aluminum body with a ceramic igniter, which the brand says gives rapid heating in cold conditions. Fuel consumption is quoted at 0.18 to 0.35 litres per hour, and VEVOR says that comes to roughly one gallon of diesel for a night. A diesel air heater typically burns more at higher settings, so actual use varies.

Power and uses

The unit has two wiring options, an adapter and a DC 12V connection. VEVOR says it suits outlets, 12/24V vehicle batteries and outdoor power stations, for cars, RVs, trucks, tractors, garages, cabins and camping. Make sure any battery or power station can supply the load the manual specifies.

Controls

There are three ways to operate it: a Bluetooth app, a remote control and the display screen on the unit. The app lets you monitor and adjust the heater from your phone, while the remote handles quick changes from across the room or cabin.

Safety features

VEVOR says the heater includes a built-in carbon monoxide alarm that monitors CO levels and either alerts or shuts the unit off. The listing adds a leak-proof fuel tank cap, a fuel level indicator and overheat protection. These are helpful extras. For any combustion heater, route the exhaust outside, follow local codes and the manual, and keep an approved CO alarm in sleeping areas.

Noise

The brand quotes noise at 75dB or lower, with a muffler and fuel pump designed to reduce sound. Expect some fan sound and fuel pump ticking, and think about how close the unit will be to where you sleep.

What to check before you buy

• Fit: measure the space for a horizontal body of about 16.5 x 10 x 12.2 inches, with room for ducting and exhaust.
• Heated area: the listing gives no floor-area figure, so match the unit to your space and insulation.
• Power supply: confirm 12V or 24V and the current your source can deliver.
• Exhaust and fuel lines: plan the routing before you mount anything.
• App compatibility: check your phone works with the Bluetooth app.
• Upkeep: diesel heaters need periodic cleaning and sometimes replacement parts, as the manual lists.
