Horizontal All-in-One Diesel Heater

Qingdao Donjelion International Trade Co., Ltd. is one of the most credible manufacturers and suppliers of Horizontal All-in-One Diesel Heater in China. If you're going to buy customized Horizontal All-in-One Diesel Heater, welcome to get more information from our factory. Good service and quality products are available.

The Donjelion Horizontal All-in-One Diesel Heater represents a significant advancement in portable heating technology. With a heat output of 6KW (±10%), this unit is engineered to deliver consistent warmth across a wide range of applications-from recreational vehicles and cargo vans to workshops and off-grid cabins.

What sets this unit apart is its dual fuel tank system: a built-in 6L tank paired with an external 10L tank, giving you a total capacity of 16L. At the lowest fuel consumption rate of 0.12L per hour, that translates to over 133 hours of continuous operation on a single fill. Even at the maximum consumption of 0.36L per hour, you're looking at roughly 44 hours of runtime-enough to get you through multiple days of off-grid use without refueling.

The unit is powered by dual brushless motors, which are critical to its performance and longevity. Unlike brushed motors that generate friction and wear over time, brushless motors operate with significantly less mechanical resistance. This means less heat generation within the motor itself, lower energy loss, and a dramatically extended operational lifespan. For buyers, this translates to fewer replacements, lower maintenance costs, and more reliable performance when you need it most-especially in remote locations where service isn't available.

The side exhaust design is another deliberate engineering choice. By positioning the exhaust on the side rather than the rear or front, Donjelion has created a unit that can be installed flush against walls or in tight compartments without risking exhaust blockage or heat damage to surrounding materials. This is particularly valuable for van conversions and small workshops where every inch of space counts.

The operating temperature range of -40°C to 70°C means this heater performs reliably in some of the harshest environments on earth. Whether you're dealing with a Canadian winter or an Australian summer, the unit maintains consistent performance.

1.Dual Fuel Tank System (6L Built-in + 10L External)

The 16L total capacity eliminates the need for frequent refueling. At 0.12L per hour consumption, you get over five days of continuous heating. For commercial operators running fleet vehicles or extended off-grid operations, this means less downtime and more productive hours.

2.Dual Brushless Motor Design

Brushless motors deliver higher efficiency, longer life, and quieter operation compared to traditional brushed motors. The absence of physical brushes eliminates friction points, reducing wear and extending the motor's service life by thousands of hours. For buyers, this means reduced maintenance costs and fewer unexpected failures.

3.Triple Voltage Compatibility (12V-24V-220V)

This unit works with 12V and 24V vehicle electrical systems as well as standard 220V AC mains power. Whether you're plugging into a truck battery, a campervan's leisure battery, or a wall outlet in a workshop, the Donjelion heater adapts instantly. This flexibility makes it a single solution for multiple applications-no need to buy different heaters for different use cases.

4.Side Exhaust Configuration

The side-mounted exhaust allows for flush installation against walls and in confined spaces. This design prevents exhaust from being blocked by rear-mounted obstacles and reduces the risk of heat damage to surrounding materials.

5.Hidden Storage Compartments

Integrated storage spaces keep cables, remote controls, and small accessories organized and protected. No more lost remotes or tangled wires-everything stays where it belongs.

6.Ultra-Low Fuel Consumption (0.12–0.36L/H)

At 0.12L per hour, this is among the most fuel-efficient diesel heaters in its class. For context, idling a typical truck engine to achieve the same heating effect consumes 1.5 to 8 liters of diesel per hour. The Donjelion heater delivers the same warmth at a fraction of the fuel cost-saving you up to 95% on heating fuel compared to engine idling.

7.Wide Operating Temperature Range (-40°C to 70°C)

Engineered with components rated for extreme conditions, this heater performs reliably in Arctic cold and desert heat alike. The ceramic igniter ensures quick starts even in sub-zero temperatures, while the aluminum heat exchanger maintains efficiency across the full temperature spectrum.

8.Low Noise Operation (≤70dB)

At or below 70dB, this unit operates quieter than a normal conversation. The combination of brushless motors and a premium muffler system keeps noise levels comfortable for sleeping, working, or relaxing.

1.Recreational Vehicles and Campervans
Keep your van warm during winter trips without idling the engine. The compact 500×300×407mm footprint fits easily into most van builds, and the dual tank system means you can heat for days without refueling.

2.Trucks and Commercial Fleet Vehicles
For long-haul drivers, this unit provides cabin heat during rest periods without the fuel waste and engine wear of idling. Fleet operators can reduce fuel costs and extend vehicle service life simultaneously.

3.Boats and Marine Applications
Diesel is already onboard most vessels. The Donjelion heater taps into that existing fuel supply while providing dry, comfortable heat for cabin spaces.

4.Workshops and Garages
The 6KW output comfortably heats spaces up to approximately 215 square feet. The side exhaust and compact design allow for installation in tight workshop corners without sacrificing floor space.

5.Off-Grid Cabins and Tiny Homes
For properties without mains electricity, the 12V and 24V compatibility means you can run this heater directly from a solar battery bank. The low fuel consumption makes it economical for extended off-grid living.

6.Emergency and Backup Heating
When the power goes out, the Donjelion heater keeps you warm. The 220V compatibility means it works with generators, while the 12V and 24V options allow for battery operation.
