Overview
A 10,000 BTU vent-free heater that runs on natural gas rather than electricity, despite how it is filed in this catalog. The blue flame burner spreads heat by convection, with legs and wall mounting hardware both included.
This is the compact natural gas counterpart to Mr. Heater's larger blue flame propane units, built for a single room rather than a whole house. An automatic low-oxygen shut-off cuts the burner if indoor air quality drops, the same safety mechanism used across Mr. Heater's vent-free line. It ships ready to either stand on its own legs or mount to a wall.
- 10,000 BTU/HR output
- Blue flame convection burner
- Runs on natural gas, no electricity
- Legs and wall mounting hardware included
Who it's for
Suits a room with an existing natural gas line where a small, unvented heater is wanted for supplemental warmth. Not a fit for anyone without gas service, or anyone specifically shopping for an electric space heater.
Pros and cons
- No electricity needed to operate
- Can stand on legs or mount to a wall
- Automatic low-oxygen shut-off included
- Requires an existing natural gas line
- Restricted above 4,500 feet altitude
- No thermostat listed in the specs
Performance notes
The blue flame tube burner heats by convection, circulating warm air through the room rather than radiating it directly, so heat spreads more evenly than a radiant tile design but takes a bit longer to feel near the unit itself. The automatic oxygen sensor shuts the burner down if the room isn't ventilating well enough for safe operation, and above 4,500 feet elevation it can trigger more readily.
