Our take on the Dyna-Glo Delux 300,000 BTU LP Forced-Air Heater

The Dyna-Glo Delux is a portable propane forced-air heater rated at 300,000 BTU, built to warm large open spaces such as warehouses, garages, construction sites and barns. It moves about 1,800 cfm of heated air and covers up to roughly 7,000 square feet, with a thermostat and automatic shut-off for hands-off control. It is a job-site and emergency-prep tool rather than a household appliance: it needs a large propane tank, ventilation and a safe distance from anything flammable. Against smaller 60,000 to 150,000 BTU torpedo heaters it trades portability and quiet for far more output, and it sits below trailer-mounted units in capacity.

Questions and answers

How much space will it heat?
It is rated for up to about 7,000 square feet, which suits large open areas like warehouses and big garages. Insulation and outdoor temperature affect real-world coverage.
Can I use it indoors?
Only in well-ventilated spaces such as open shops or construction sites. It burns propane and produces exhaust, so never use it in a sealed home or bedroom.
What size propane tank does it need?
It needs a large LP cylinder, typically a 100 lb tank or larger, with the right hose and regulator. A small camping cylinder will not feed 300,000 BTU.
Does it have a thermostat?
Yes. The built-in thermostat cycles the burner to hold your set temperature, and automatic shut-off and overheat protection add safety.
How loud is it?
The forced-air fan is loud, similar to other high-output torpedo heaters. Expect to raise your voice near it.
Is it hard to move?
It weighs about 33 lbs and sits on a compact frame, so one person can move it, but lifting it into a truck or onto a shelf takes effort.
