Best Chinese Diesel Heater Review

The Maxpeedingrods was chosen as the best Chinese diesel heater because of its value for the money. It is relatively inexpensive for the power that it has and runs at least a full day on a charged battery, and the fuel consumption is about 1 gallon per night. 

The remote control has a range of 30 meters, which is really helpful for warming up your space without needing to be out in the cold. The intelligent overheating sensor will prevent the heater from running dry, and does an excellent job at eliminating window frost. It has a quiet night-time operation, temperature control, and a dynamic LCD display. 


  • Auto temperature control
  • Efficient operating with low fuel consumption
  • Quiet operation
  • Compact and sleek design


  • Controls read in Celcius
  • The instruction manual can be hard to follow

Trial Results

Using this in a 15-foot camper during the winter, when temps were in the single digits, was the best choice we made! We ran it for nearly 2 days straight and because we have solar panels, they were able to quickly recharge the heater after each night’s use. We also upgraded to a larger diesel tank so we wouldn’t have to refill it is as often. While the installation was not as straightforward as I would have hoped, this was due to the hard-to-understand interaction manual more than anything else. All in all, this is a great heater, especially for the price. 

This 8kw Chinese indoor diesel heater was added to our list because it has many high customer satisfaction ratings and low fuel consumption. The kerosene & diesel fuel heater is strong enough to warm almost any car, van, truck, boat, or vehicle of your choice, and depending on the size of your vehicle, this device will heat it up in about 5 – 5 minutes. 

With its small size, it’s easy to find the perfect space to mount this device. It is recommended to check out Youtube for installation, as the instruction manual is poorly written.  While the machine does produce some noise during operation, you can install a silencer that will help cut down on that. 

This kit comes with a 10L oil tank, which has a run time of about 36 hours. 


  • Low noise
  • Temperature control
  • Low fuel consumption
  • Long-lasting


  • Low-quality LCD Screen, better to upgrade to the button remote
  • The instructions are hard to understand

Trial Results

We installed this in our sprinter van before a weekend trip to the mountains and it kept us warm all night long. The fuel pump is not quiet and would “knock” while running, but the heater was much quieter. The controls were not very intuitive and the instruction manual was not very good quality, but we figured things out and were happy overall with this heater. 

The Tseipoaoi indoor diesel heater is another great option for a Chinese diesel heater. This heater was chosen for our list because of its high-performance rating and low cost. 

With an intuitive and easy-to-read display, this heater is a great choice for a wide variety of diesel vehicles. It is compact which makes installation easy, as you have more options for where it can be placed. It has a low fuel consumption rating, which contributes to its low emissions, and the oil quantity, temperature, and wind speed can all be adjusted. This gives you maximum control over your heating needs. 


  • Adjustable oil quantity
  • Efficient operation with low fuel consumption
  • Advanced technology for optimal temperature control


  • Hard to understand instructions
  • More parts needed for marine use

Trial Results

We installed this in our camping trailer, which we use in the winter to go up to the mountain. Having a heater for overnights is essentially, as the temperature drops considerably. The instructions were not as bad as the other two on our list, though there were still some parts that took some figuring out. After installation we ran the parking heater for 12+ hours and had no problems with overheating and it ran very well.

This is a powerful space heater, at 80,000 BTUs it can easily heat up a 2000 square foot space. With its built-in handle it’s super easy to take with you, though don’t go moving it while it’s in use!

Stanley is a very recognized brand within the hardware sector and this space heater is built with quality parts. Although users report that it can be a little loud, it heats up very quickly and comes in at a very affordable price.

This model has an easy-to-read thermostat dial, fuel and pressure gauge, and automatic safety shutoff system. 


  • 80,000 BTUs
  • Heats up to 2000 sq. ft.

Used in our three-car garage, this space heater worked really quick! It was very easy to get it started and the dial makes adjustments intuitive. Seems to be made with quality parts and the easy-lift handle is a great feature.
Like the Stanley, this space heater has a built-in handle and runs at 80,000 BTUs. It also has a runtime fuel gauge, pressure gauge, and an easy-to-access help center based on scanning the QR code with your phone. 

The temperature gauge is easy to read and access, with a very intuitive options display. It can be adjusted in 10-degree increments and burns about .5 gallons per hour of use. 


  • Heats up to 1900 sq. ft.
  • 80,000 BTU
  • Thermostat for heat control
  • Run time fuel gauge


  • Smokes when starting and stopping
  • It doesn’t always light up right away

Trial Results

We tried this out in our 3 car garage in the dead of winter and it quickly brought the temperature up from 25°F to 75°F. It was noisy as all diesel space heaters are, and it didn’t light up right away every time, but other than that it worked really well at heating the space. 


The Pro-Temp Diesel space heater on our list is rated at 45,000 BTU and can heat an area up to 1125 square feet. While not as powerful as the others on our list, this is a great space heater for a smaller space. With the temperature outside at 50 degrees, within an hour and a half the temp went up to 80, so it may take a little longer but it gets the job done. 

This space heater has a fuel and pressure gauge, built-in handle, and a simple start up switch. 


  • 45,000 BTU
  • Heats up to 1125 sq. ft.
  • Operates for up to 14 hours straight
  • Air pressure gauge


  • The smell is a little stronger than the others on our list
  • The thermostat does not automatically turn the space heater back on

Trial Results

While this space heater does not run as strongly as the others, it does a great job of heating up our garage. Once we added the fuel, starting it up was as easy as flipping a switch. The fuel and pressure gauges were very basic and easy to read as well. The downside is that because it doesn’t burn as hot, it seems to not burn as clean, as the smell was a little stronger than with the other space heaters on our list. Regardless, it did a great job heating up our 3-car garage, even if it did take a little longer than the Stanley and Dyna-Glo.
