Portable Heaters for Jobsites, Garages, and Shops

Match the BTU Rating to the Space You Heat

A portable heater is sized by BTU output against the square footage and insulation of the area. Mi-T-M's forced-air line spans 60,000 BTU for a 1,500 square foot garage up to 600,000 BTU for a 15,000 square foot warehouse or open construction floor. Radiant tank-top and convection models cover spot heating and 360-degree coverage where a directed air stream is not the goal. Undersizing leaves a space cold in the corners; oversizing burns fuel faster than the room needs, so the rating on the unit should track the room, not the biggest number available.

Fuel Type Decides Where the Heater Can Run

Kerosene and multi-fuel forced-air heaters throw a high-BTU air stream and suit open, well-ventilated construction sites. Propane forced-air units light instantly, run clean, and pair with the 20-pound or 100-pound cylinders most crews already keep on site. Natural-gas models tie into a building's supply line for continuous heat with no refueling. Every fuel-burning heater consumes oxygen and produces exhaust, so adequate ventilation and a working carbon-monoxide detector are not optional. Follow the CDC's carbon monoxide guidance and the CPSC heating safety center when running any combustion heater indoors.

Choose the Form Factor for the Job

Forced-air heaters move the most air and heat the most space, which is why they dominate construction and disaster-restoration work. Radiant tank-top heaters warm the people and surfaces directly in front of them and need no electricity, useful on open sites and for hunters and outdoor crews. Convection heaters push heat outward in every direction and suit the center of a large open floor. Related: Forced Air Heaters · Propane Heaters · Kerosene Heaters. For a high-output enclosed jobsite, the MH-0400 kerosene forced-air heater covers up to 10,000 square feet on a single tank.

Frequently Asked Questions

What size portable heater do I need for a 2-car garage?
A 1,500 to 2,000 square foot garage needs roughly 45,000 to 60,000 BTU with average insulation. A 60,000 BTU propane forced-air heater covers a standard two-car garage; add capacity for high ceilings or poor insulation.
Are portable heaters safe to use indoors?
Combustion heaters can run indoors only with adequate ventilation and a working carbon-monoxide detector. Forced-air and convection units need fresh-air makeup; never run one in a sealed space. Electric-start models still burn fuel and produce exhaust.
What is the difference between forced-air and radiant heaters?
Forced-air heaters blow heated air to warm a whole space fast. Radiant heaters warm people and objects directly in their path without moving air, which works better outdoors or for spot heating a work station.
Do these portable heaters ship by freight?
Larger forced-air and convection units ship by LTL freight on a pallet. Smaller tank-top and cabinet heaters ship by ground. Delivery timing shows at checkout.
