Overview

The ProCom ML100TBA-B is a 10,000 BTU liquid propane heater with blue flame convective heat, sized to warm a room up to 500 square feet without any electrical connection. It offers High, Medium and Low thermostat settings and can be wall mounted or set on its included base feet.

Blue flame heaters warm a room the way a radiator does, by heating the surrounding air rather than throwing a directional beam. This one is built for indoor use in a bedroom, living room or office, and the push button ignition pairs with an oxygen depletion sensor that shuts the heater off if oxygen levels in the room drop too low. Because it runs on liquid propane rather than a plug, it also works during a power outage.

  • 10,000 BTU on liquid propane
  • Heats spaces up to 500 sq ft
  • High / Medium / Low thermostat control
  • Push button ignition with ANSI certified ODS shutoff

Who it's for

Fits anyone who wants supplemental propane heat in a room without running an electrical line to it, including off grid spaces, older homes without enough outlets, and households that want a backup heat source for outages. Less suited to large open floor plans, where 500 square feet of coverage will fall short.

Pros and cons

Pros
  • No electrical hookup needed
  • Three heat settings via thermostat
  • ANSI certified with automatic oxygen sensor shutoff
  • Wall mountable or freestanding on base feet
Cons
  • Requires liquid propane tank refills
  • 500 sq ft is the maximum, not guaranteed
  • Ventless heaters still need room ventilation

Performance notes

The Blue Flame design circulates heat through natural convection, so the whole room gradually warms rather than just the area directly in front of the unit. The three way thermostat cycles the burner between High, Medium and Low to hold a set temperature instead of running at full output constantly, and the built in oxygen depletion sensor cuts gas flow automatically if oxygen in the room falls, a required safety feature for any unvented indoor propane heater.

Frequently asked questions

Does the ProCom ML100TBA-B need to be plugged in?

No. It runs on liquid propane and needs no electrical connection, which is part of why it works during power outages.

What's the difference between this and the ML100TPA-B infrared version?

This ML100TBA-B is the Blue Flame model, which heats a room through convection, while the TPA-B is an infrared plaque heater that radiates heat toward whatever's in front of it.

How large a room can it heat?

ProCom lists coverage up to about 500 square feet at its 10,000 BTU maximum output.
