Overview
The ProCom ML100TPA-B is a 10,000 BTU liquid propane infrared heater rated to cover up to 500 square feet, using a radiant plaque instead of an open blue flame. It has High, Medium and Low thermostat settings and comes with hardware for either wall mounting or the included base feet.
Infrared heaters warm objects and people in their line of sight rather than heating the surrounding air, so this model works most effectively pointed at where someone actually sits, like a desk chair or a sofa, rather than trying to raise the temperature of an entire room evenly. Like the rest of ProCom's TPA/TBA line it needs no electricity, uses push button ignition, and includes an oxygen depletion sensor that shuts the unit down if the room's oxygen level drops.
- 10,000 BTU infrared plaque heater
- Liquid propane, up to 500 sq ft rated coverage
- High / Medium / Low thermostat
- Push button ignition with ODS safety shutoff
Who it's for
Good for someone who wants to heat a specific spot, a workbench, a reading chair, a garage corner, rather than an entire room evenly. Not the right pick for someone who wants heat spread through convection across a whole living space.
Pros and cons
- No electrical hookup required
- Directs heat where it's aimed, not the room
- ANSI certified oxygen depletion sensor shutoff
- Wall mount or freestanding base feet included
- Heats what's in front of it, not the room
- Needs liquid propane tank refills
- Still requires adequate room ventilation
Performance notes
Radiant infrared heat travels in a straight line and warms surfaces and people directly in its path rather than the air in between, so it's felt fastest close to the unit and directly in front of it. The High/Medium/Low thermostat adjusts how hard the burner runs, and the same oxygen depletion sensor found on ProCom's other ventless models cuts the gas supply if oxygen in the room drops too far.

Frequently asked questions
How is this different from a blue flame heater?
Infrared heaters like this one radiate heat directly at people and objects in front of them, while blue flame heaters warm the air in the room through convection.
Does it need electricity?
No, it runs entirely on liquid propane with push button ignition.
What safety features does it have?
It includes an ANSI certified oxygen depletion sensor that automatically shuts the heater off if oxygen levels in the room drop.
