Dyna-Glo 30,000 BTU Liquid Propane Wall Heater

Check Price on Amazon

This vent-free blue flame wall heater is intended for mounting and is designed to convect heat similar to central systems. It is specified as liquid propane ready with no fuel conversion permitted. The unit provides a variable output between 24,000 and 30,000 BTU/hr and is rated to warm up to about 1,000 square feet. The blue flame design distributes warmth through air convection rather than radiant tiles.

Key operational aspects include continuous vent-free combustion and adjustable heat output for larger rooms. Users should be aware that vent-free models rely on indoor air for combustion and are subject to local codes and ventilation considerations. Recommended locations are spaces where vent-free heaters are allowed and where adequate air exchange exists.

Mr. Heater MHVFBF20LPT 20,000 BTU Wall Heater

Check Price on Amazon

This 20,000 BTU vent-free blue flame propane wall heater targets spaces up to about 700 square feet. It includes a thermostat for temperature control and a battery-powered electronic ignition for startup, with battery included. Fuel consumption is specified as ~0.926 lbs per hour at maximum output.

Safety is emphasized with an automatic low-oxygen shut-off system (ODS) that stops operation if ventilation is insufficient. The unit is rated for reliable operation at elevations up to 4,500 feet, which may be relevant for higher-altitude installations. As a vent-free device, it requires adherence to ventilation guidelines and local installation codes.

Mr. Heater 30,000 BTU Vent Free Radiant Heater

Check Price on Amazon

This model uses infrared radiant technology with multiple burner tiles to warm people and objects directly, rather than primarily heating air. It provides 30,000 BTU of output and is rated for spaces up to about 1,000 square feet. The design aims to deliver efficient, sun-like warmth and is positioned as a supplemental heat source for rooms, additions, and cabins.

Fuel efficiency is specified with a consumption rate leading to extended runtimes from standard propane cylinders when used within recommended operating parameters. Being vent-free, it shares the same regulatory and indoor-air considerations as other vent-free appliances; installation should follow manufacturer and local code requirements.

Comfort Glow 11,000 BTU Direct Vent Propane Heater

Check Price on Amazon

This direct vent liquid propane wall heater uses a sealed combustion design, which draws combustion air from outside and exhausts directly outdoors. It produces 11,000 BTU and is rated to heat up to approximately 375 square feet. The sealed system reduces indoor combustion byproducts in the living space compared to vent-free units.

Safety features include a matchless piezo ignition, a safety pilot, and a built-in pressure regulator that stops gas flow if the pilot is extinguished. Its compact, wall-mounted form factor is suitable for smaller rooms, garages, or areas where a sealed combustion approach is preferred or required by local codes.

Dyna-Glo Signature 20,000 BTU Thermostatic Wall Heater

Check Price on Amazon

The Signature Series is a thermostatic vent-free blue flame heater with adjustable output from 16,000 to 20,000 BTU. It is designed to convect heat to warm air similar to centralized systems and is suitable for spaces up to about 700 square feet. It is specified as liquid propane ready with no conversion allowed.

Thermostatic control provides automatic temperature regulation for steady comfort. As with other vent-free products, installation must consider local codes and ventilation; the unit is optimized for rooms where vent-free operation is permitted and practical.

Buying Guide: How To Choose A Mounted Propane Heater

Selecting the right mounted propane heater involves evaluating heat output, venting type, mounting and installation, safety systems, fuel consumption, and local code requirements. Below are key factors and comparison perspectives to guide your choice.

Heat Output And Coverage

• BTU Rating: Match the heater’s BTU output to room size. Higher BTU models (20,000–30,000+) suit larger rooms and open layouts, while 8,000–12,000 BTU units work for smaller areas.
• Coverage Estimates: Manufacturers provide approximate square footage. Use these as starting points and adjust for insulation, ceiling height, and climate zone.

Vented vs Vent-Free (Sealed Versus Open Combustion)

• Vent-Free (Blue Flame, Radiant): Efficient heat transfer to indoor space and simpler installation, but they release combustion products indoors and are regulated in some jurisdictions. Good for supplemental heat in permitted areas.
• Direct Vent (Sealed Combustion): Draws air from outside and exhausts outdoors, improving indoor air quality and meeting stricter code requirements. Preferred where indoor combustion is a concern.

Heating Method: Convection Versus Radiant

• Convection (Blue Flame): Warms the air and circulates heat through the room—good for even whole-room warmth.
• Radiant (Infrared): Heats objects and people directly. Radiant units can feel warmer at lower air temperatures and are effective for spot heating or rooms with high ceilings.

Safety Features And Certifications

• ODS (Oxygen Depletion Sensor): Shuts the heater off if indoor oxygen levels drop; common on vent-free models.
• Pressure Regulators And Safety Pilots: Prevent gas flow if ignition fails.
• Thermostatic Controls: Maintain temperature and reduce cycling, improving safety and efficiency.
• Local Codes: Verify local building and fire codes; some areas restrict vent-free appliances or require direct venting for specific room types.

Installation And Mounting Considerations

• Wall Mounting: Confirm wall structure and clearances. Follow manufacturer spacing and combustible-clearance specifications.
• Venting Path: For direct vent models, plan the exhaust path and ensure proper sealing through the wall. Vent-free units simplify installation but still require clearance and proper air exchange.
• Fuel Supply: Ensure proper propane cylinder or piping setup and regulator sizing for mounted use.

Operational Efficiency And Fuel Use

• Consumption Rates: Review fuel consumption (lbs/hr) for runtime planning with portable cylinders or propane supply demands for permanent installations.
• Thermostatic Control Vs Manual: Thermostatic models can reduce runtime and save fuel by maintaining set temperatures.

Environment And Use Case Perspective

• Indoor Living Areas: Direct vent heaters are often preferred for bedrooms, tightly sealed homes, and for meeting stricter indoor-air requirements.
• Workspaces, Garages, Cabins: Vent-free units are frequently used for workshops, cabins, and intermittent spaces where code allows and ventilation is manageable.
• High Altitude: Confirm manufacturer elevation ratings; some products specify reliable operation up to certain altitudes.

Maintenance And Longevity

• Regular Inspection: Check burners, pilots, and seals annually. For direct vent systems, inspect the vent path for blockage.
• Service Access: Consider units that provide outside access to controls and connections to simplify maintenance.

Comparing The Reviewed Models

• Dyna-Glo 30k: Higher output vent-free blue flame suitable for larger rooms where vent-free is allowed; convective heat distribution.
• Mr. Heater 20k: Mid-range vent-free unit with thermostat and ODS; rated for moderate coverage and altitude capability.
• Mr. Heater 30k Radiant: Radiant option for direct warmth to people and objects; good for spot heating and spaces where radiant efficiency is desired.
• Comfort Glow 11k: Direct vent sealed-combustion choice for smaller rooms where indoor air quality or code requires external combustion air.
• Dyna-Glo Signature 20k: Thermostatic vent-free model offers adjustable output and convection-based distribution for mid-size rooms.

Final Selection Checklist

• Confirm allowed appliance types in your jurisdiction (vent-free vs direct vent).
• Measure space and choose appropriate BTU capacity with margin for insulation and climate.
• Decide between convection and radiant heat based on usage patterns.
• Verify installation clearances, wall mounting suitability, and fuel connection needs.
• Prioritize required safety features such as ODS, sealed combustion, and thermostatic control.
