Specifications side by side

DEWALT Heaters Compared by Specs

The first model is a 68,000 BTU propane unit. It measures 13 by 17 by 20 inches and weighs 15.1 pounds. This forced air heater suits large, ventilated spaces like warehouses. You get high output and portable power for job sites.

The second option is a 5,630 watt electric construction heater. It is smaller at 14.3 by 14.4 by 11.1 inches. It weighs 15.3 pounds. This unit fits small indoor workspaces. You prioritize safety and durability over raw heat power here.

Where DEWALT Fits Your Needs

DEWALT offers two distinct options for your workspace. You can choose a large 68,000 BTU propane unit for big, ventilated areas or a smaller 5,630 BTU electric model for tight indoor jobsites. Both are portable forced air heaters. The propane model weighs 15.1 pounds, while the electric version is slightly heavier at 15.3 pounds. Neither unit includes smart features or remote controls in the listed specs. You should know that this range does not cover medium-sized electric heaters or high-capacity natural gas units. If you need something between these two extremes, DEWALT does not currently list a model for that specific gap.

How to choose the right DEWALT garage heater

1. Match BTU to space size

   You must align the heating output with your garage volume. The top model delivers 68,000 BTUs, which is ideal for large, ventilated areas like warehouses or big workshops. If your space is smaller, that output may be excessive. The second option provides 5,630 BTUs, making it suitable for compact indoor job sites. Check the square footage of your room first. Higher BTU numbers mean more heat, but you only need what fills your specific area efficiently without wasting energy or fuel.

2. Select the correct power source

   Your available power determines which unit fits your workflow. The first heater runs on propane, offering portability and independence from electrical grids. This is best for job sites without reliable power. The second unit is electric, requiring a standard outlet. Electric models are safer for enclosed spaces with limited ventilation. Decide if you need fuel flexibility or the convenience of plugging in. Propane units provide high heat anywhere, while electric options offer steady power where outlets are accessible and ventilation is managed.

3. Verify forced air heating method

   Both models use forced air technology to distribute warmth. This method pushes heated air quickly across the room, raising temperatures faster than radiant heaters. You get immediate warmth in drafty garages or large open spaces. Forced air systems are effective for working environments where you need to heat the air itself. Ensure your space allows for air circulation. This heating style is practical for job sites where you move around and need consistent ambient heat rather than spot warming.

4. Check physical dimensions for storage

   Measure your storage area before buying. The propane heater is 13 by 17 by 20 inches, taking up more floor space. The electric model is smaller at 11.1 by 14.4 by 14.3 inches. Consider where you will keep the unit when not in use. Portability matters if you move the heater between rooms or job sites. The electric unit is slightly lighter and more compact. Ensure you have enough clearance around the heater for safe operation and easy access to controls or power cords.

5. Assess portability and weight

   Weight affects how easily you can move the heater. The propane model weighs 15.1 pounds, while the electric version is 15.3 pounds. Both are portable, but the size difference matters more for maneuverability. You can carry either one, but the electric unit’s smaller footprint makes it easier to tuck away. Consider if you need to lift the heater into a truck or up stairs. Both are designed for job sites, so ensure you have a safe way to transport them to your workspace without strain.
