Comfort Glow 17,000 BTU Direct Vent
This direct vent propane wall heater uses a sealed-burn system and is designed to vent combustion gases outdoors, which is important where indoor air quality is a priority. The unit delivers 17,000 BTU and is rated to heat up to 570 sq. ft.
- Sealed Burn System: Reduces indoor combustion byproducts and improves safety.
- Safety Pilot & Pressure Regulator: Built-in features stop gas flow if the pilot is extinguished.
- Space-Saving Wall Mount: Slim profile intended for wall installation in living spaces.
While the listing emphasizes safety and vented operation, it does not explicitly list an adjustable thermostat in the features. For installations that require vented combustion, the sealed burn and pressure regulation make this model relevant for homeowners prioritizing vented heaters.
Comfort Glow 11,000 BTU Direct Vent
The 11,000 BTU direct vent Comfort Glow model provides sealed combustion and is suited for smaller rooms or supplemental heating. It is designed to mount on a wall and directs exhaust outdoors through a vent.

- Heats Up To 375 Sq. Ft.: Suitable for bedrooms, small living rooms, or dens.
- Matchless Piezo Ignition: Simplifies pilot lighting without batteries.
- Safety Pilot & Built-In Pressure Regulator: Helps prevent gas flow if pilot goes out.
This heater prioritizes safety and sealed combustion for indoor air quality. The features list does not explicitly state a programmable thermostat, so pairing with room temperature controls or selecting a model with integrated thermostat may be preferred depending on temperature control needs.
Mr. Heater 20,000 BTU Blue Flame
This vent-free blue flame heater includes an integrated thermostat for accurate temperature control and electronic ignition powered by a battery. The design is aimed at delivering heat efficiently into living spaces.
- 20,000 BTU Output: Claimed coverage up to 700 sq. ft. and suitable for larger rooms or open areas.
- Thermostat Control: Built-in thermostat enables setpoint-based operation for comfort.
- ODS Safety: Oxygen Depletion Sensor automatically shuts unit off in low-oxygen conditions.
- Battery Electronic Ignition: Battery included for easy startup.
Because this is vent-free, combustion products are released into the room; the ODS and thermostat improve safe, controlled use, but vent-free operation may not be suitable for all spaces or local codes that require venting.
ProCom ML100TPA-B 10,000 BTU
The ProCom ML100TPA-B is a compact ventless infraredthermostat control and multiple heat settings. Its design emphasizes simple thermostat-driven comfort for smaller areas.

- Thermostat Control: High/Medium/Low thermostat settings allow room temperature regulation.
- 10,000 BTU Capacity: Rated to heat spaces up to ~500 sq. ft., depending on insulation and layout.
- Mounting Options: Includes wall-mount hardware and base feet for freestanding use.
- Modern Slim Profile: Intended to blend with interior decor while providing infrared warmth.
As a ventless infrared unit, the ProCom enables straightforward heat delivery and thermostat cycling, but venting considerations and local codes should be reviewed before selecting a ventless model for a given room.
Bluegrass Living 18,000 BTU Infrared
The Bluegrass Living infrared heater offers T-stat control and an 18,000 BTU output intended for larger spaces, including garages and open living areas. It is described as a vent-free, highly efficient infrared option.
- Thermostat Cycling: Automatic on/off to maintain set temperature.
- Wide Coverage Claim: Up to 950 sq. ft. in ideal conditions.
- Vent-Free Efficiency: High combustion efficiency but releases combustion products into the room.
- Blower & Base Feet: Includes blower for heat circulation and flexible placement options.
This unit is relevant where thermostat-based cycle control and high output are priorities. For spaces where venting is required, consider direct vent alternatives instead.
Buying Guide: How To Choose A Propane Heater With Thermostat
Selecting the right propane heater with thermostat requires attention to venting type, safety features, sizing, and local code compliance. Below are key considerations and comparative perspectives to help you decide.
Tips for Getting the Best HVAC Prices

Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
Vented (Direct Vent) Versus Vent-Free (Ventless)
- Direct Vent (Vented): Sealed combustion draws air from outdoors and exhausts outside. Best for indoor air quality concerns, bedrooms, and locations where combustion byproducts must be isolated.
- Vent-Free: Burns gas in the living space and is typically more efficient at heating air but releases combustion products indoors. May be restricted by local codes or unsuitable for poorly ventilated spaces or homes with occupants sensitive to indoor pollutants.
Thermostat And Control Features
- Integrated Thermostat: Built-in thermostats provide automatic setpoint control and can reduce fuel use by cycling the heater.
- External Controls & Programmability: Some units pair with remote thermostats or wall controls for scheduling and finer temperature management.
- Precision: Look for thermostats with a clear range and reliable cycling to avoid wide temperature swings.
Safety Features
- Oxygen Depletion Sensor (ODS): Shuts the unit off if oxygen levels drop; common in vent-free models.
- Sealed-Burn & Pressure Regulator: Standard on direct vent units to prevent indoor exposure to combustion products.
- Automatic Shutoff: Overheat and pilot safety systems reduce risks with unattended operation.
Sizing: BTU Output And Coverage
- Calculate Heat Load: Use square footage, ceiling height, insulation quality, and climate to estimate BTU needs. Manufacturer coverage is a guideline, not a guarantee.
- Room Function: Living rooms and open plans may need higher BTU; bedrooms and small dens often require lower output.
Installation And Venting Considerations
- Direct Vent: Requires routing a vent through an exterior wall or chimney system—often professional installation is recommended.
- Vent-Free: Easier to install but confirm local building codes and ensure adequate ventilation and clearance.
- Clearances & Mounting: Confirm manufacturer clearance requirements for wall mounting and nearby combustible materials.
Energy Efficiency And Fuel Consumption
- Vent-Free Efficiency: Often near 99% in delivered heat but can affect indoor air quality.
- Direct Vent Efficiency: Slightly lower space-heating efficiency due to venting losses but offers cleaner indoor air and safer long-term operation.
Maintenance And Longevity
- Annual Inspection: All gas heaters benefit from periodic checks of burners, ignition systems, vents, and safety sensors.
- Replace Filters/Blowers: If the unit includes a blower, keep blades and motors clear of dust to preserve airflow and performance.
Local Codes, Health, And Occupant Needs
- Check Local Regulations: Some jurisdictions restrict or prohibit vent-free heaters in specific rooms or dwellings.
- Health Considerations: Households with asthma or chemical sensitivities may prefer direct vent systems to avoid added indoor combustion byproducts.
Comparison Perspectives
- Safety-Focused: Prefer direct vent models with sealed combustion and pressure regulators.
- Convenience-Focused: Vent-free units with integrated thermostats provide straightforward heat control without vent installation.
- Budget & Installation: Factor installation complexity and potential need for professional venting when comparing total ownership costs.
