Factors to Consider When Buying a Heater for your Box Truck

Indeed there are certain critical factors to consider when purchasing a heater for your box truck. Those factors include;

  • The power source: Note that different heaters leverage different types of fuel. If you want one that runs on electricity, convection and ones that plug into your truck lighter port are good options. If you prefer a fuel-burning unit, choose one that uses propane, however, they are not always recommended.
  • The effort required: A good number of heaters require more work to install and maintain. You will find heaters that require some tools and hard wiring to ensure a good installation. Make sure you extensively consider your truck before making this decision.
  • Size of your truck: For every 10 watts, the heater you intend on purchasing can heat at least 1 square foot of space. If you want to keep it portable, most heaters you are considering will typically use 750 to 1500 watts of electricity. It simply means that these heaters can heat between 75 to 150 square feet.
  • Tip-Over Safety Switch: According to experts, this safety function is for accidents. If the heater is on and is tipped or knocked over on accident, the heater will automatically shut off to help prevent fires from starting.
  • Automatic Shut-off Timer: This safety feature is very important especially since it works just like a sleep timer on the TV. Note that heaters with this feature will allow you to set an automatic shut-off time for up to 10 or 12 hours.
  • Overheat Protection: This is another valid option to consider. If the heater malfunctions and heats up over the factory set safety temperature, this feature automatically shuts off the heater.
  • Budget: Another important factor to consider is your budget. Note that certain vehicle heaters provide potential energy savings, but they can be quite expensive to install and maintain.


There are numerous options to pick from when it comes to heating a box truck. However, when buying a Heater for your box truck, ensure to take into consideration factors such as size, type, material, power requirements, and controls to ensure you get one that best aligns with your needs.

Also, do not forget to adhere to safety protocols noted by the manufacturer, keeping heaters away from flammable items, and turning off heaters when not in use.
