Operating a semi truck can be a challenging occupation, especially during cold temperatures. In order to maintain a comfortable and warm environment within the truck’s sleeper cab, a reliable and efficient space heater is essential. Space heaters come in various styles, sizes, and power options suitable for semi trucks, ensuring drivers have access to a cozy and inviting space during rest periods.

Space heaters designed for semi trucks are unique in that they need to be compact, energy-efficient, and safe to use in confined spaces. Truck drivers are faced with the challenge of finding a perfect balance between size, heat output, and energy consumption. As a result, it is crucial to consider factors such as safety features, energy usage, and ease of installation when making a purchase.

Moreover, the durability and performance of the space heater are also essential aspects to evaluate before making a decision. A well-built space heater should be able to withstand the rigors of life on the road and provide consistent, dependable warmth for the driver during rest stops or overnight stays.

Best Space Heaters for Semi Trucks

In this article, we have compiled a list of the best space heaters for semi trucks to keep you warm and comfortable during those long hauls. Enjoy our top picks and find the perfect one for your needs.

RoadPro RPSL-681 12V Direct Hook-Up Ceramic Heater/Fan w/Swivel Base

RoadPro RPSL-681

If you need a basic heater for your semi-truck, this RoadPro model might be a reasonable choice, but don’t expect powerful heating capabilities.


  • Easy to hook up to your vehicle battery
  • Offers heat to cool setting switch
  • Comes with installation hardware


  • Limited heating performance
  • May drain battery if not properly wired
  • Build quality leaves room for improvement

We recently tried the RoadPro RPSL-681 12V Direct Hook-Up Ceramic Heater/Fan in our semi-truck during a cold trip. The installation was straightforward, thanks to the included hardware. Connecting the heater directly to the vehicle’s battery was a nice feature, and the ability to switch between heat and cool settings was quite convenient.

However, the RoadPro RPSL-681’s heating performance left us somewhat disappointed. It generated only a modest amount of heat, and we felt it could have benefitted from a more powerful blower. Moreover, we noticed that the battery might drain quickly if the heater is not wired properly or used with a smaller battery or insufficient amperage alternator.

The build quality of the RoadPro RPSL-681 also appeared to be less durable compared to some other heaters we’ve used in the past. That said, it is an affordable option for a semi-truck heater, and it might be satisfactory if you are not looking for a high-performance heater to keep you exceptionally warm during the coldest days.

Additionally, the 70° wide-angle oscillation effectively directed heat throughout the cabin.

However, we noticed that the heater required frequent filter cleaning, which might be a bit inconvenient for some users. Also, the maximum heating coverage of 200 square feet might not be suitable for larger trucks or spaces. Lastly, a few users reported a slight noise issue while using the oscillation feature, although this was not a deal-breaker for us.

Safety Features

Safety should be your top priority when selecting a space heater for your semi-truck. Look for models with built-in safety features, such as:

Energy Efficiency

Fuel usage and power demands are important factors to consider when choosing a space heater for your semi-truck. Look for energy-efficient models with adjustable settings, such as low, medium, and high heat options. This helps you save on fuel costs and manage your truck’s power consumption more effectively.


Given the limited space in a semi-truck, you’ll want a compact and easily portable space heater. Handle designs and lightweight models make it easier to move the heater around your truck’s cab and ensure it can easily fit in tight spaces.

Noise Level

A quiet space heater is essential when driving long distances, as excessive noise can be quite distracting. Look for models with a low decibel (dB) rating to ensure the heater won’t disturb your rest during breaks or create unnecessary background noise while driving.

Power Source

Consider the power source for your space heater. Some may require hooking up to your truck’s electrical system, while others may have battery-powered options. Ensure the heater you choose is compatible with your truck’s power supply and that it won’t strain your truck’s electrical system.
