Dyna-Glo IR30PMDG-1 30,000 BTU Infrared Wall Heater

Check Price on Amazon

This Dyna-Glo model is a liquid propane ready infrared wall heater designed for vent-free installation. The unit uses infrared technology to radiate heat directly to objects and people rather than relying solely on air convection, which often delivers a faster perception of warmth.

Features listed include a variable heat output from 6,000 to 30,000 BTU/hr and stated coverage up to 1,000 square feet. The manufacturer notes that fuel conversion is not permitted, meaning the unit must be used with the specified fuel type as shipped.

Suitable spaces: larger rooms where radiated heat is preferred. Installation considerations include vent-free operation and local code compliance for unvented propane appliances.

Comfort Glow 11,000 BTU Direct Vent Propane Heater

Check Price on Amazon

The Comfort Glow 11,000 BTU unit is a direct vent (vented) propane wall heater intended for medium-sized rooms. The sealed burn system draws combustion air from outside and vents exhaust outdoors, reducing indoor combustion byproducts.

Key features: 11,000 BTU heating capacity with coverage up to 375 square feet, Matchless Piezo ignition, a safety pilot and built-in pressure regulator that stops gas flow if the pilot is extinguished. The compact dimensions make it a space-saving wall-mounted option.

Suitable spaces: bedrooms, small living rooms, or finished basements where venting to the outside is practical and preferred for indoor air quality.

Comfort Glow 17,000 BTU Direct Vent Propane Heater

Check Price on Amazon

The larger Comfort Glow direct vent model increases output to 17,000 BTU, with estimated coverage up to 570 square feet. Like the 11k model, it uses a sealed burn system and safety pilot with pressure regulation to cut gas flow if the pilot goes out.

Additional notes: This heater maintains the space-saving wall mount footprint but with a wider face to accommodate higher output. Dimensions and venting needs should be evaluated before placement.

Suitable spaces: mid-sized living spaces requiring vented combustion for improved indoor air quality and consistent heat distribution.

ProCom ML250TPA-B 25,000 BTU Ventless Infrared Heater

Check Price on Amazon

The ProCom ML250TPA-B is a ventless infrared wall or floor-mount unit offering up to 25,000 BTU and thermostat control with High/Medium/Low settings. The product states heating coverage up to 1,150 square feet and includes wall-mount hardware and base feet for flexible placement.

Features highlighted: thermostat control for temperature regulation, compact modern profile, and both wall or floor installation options. As a ventless heater, it introduces combustion products into the room, so adherence to local codes and adequate ventilation is important.

Suitable spaces: larger rooms, open-plan areas, or workshops where radiated vent-free heat is acceptable per local regulations.

Dyna-Glo 30,000 BTU Blue Flame Vent Free Wall Heater

Check Price on Amazon

This Dyna-Glo blue flame vent-free wall heater offers variable output rated between 24,000 and 30,000 BTU and is specified for liquid propane. The blue flame technology provides convection-based heating that warms air to circulate heat similarly to central systems.

Manufacturer notes include mounting type: wall mount and a stated service area up to 1,000 square feet. The product is labeled as liquid propane ready with no fuel conversion permitted.

Suitable spaces: larger enclosed rooms where convective heat distribution and vent-free installation meet local code allowances.

Buying Guide: Choosing A Propane Wall Heater

This guide covers critical considerations when selecting a propane wall heater, including safety, performance, and installation factors. Compare multiple perspectives to match equipment to needs and codes.

Heat Output And Room Size

• BTU Rating: Match BTU capacity to room square footage. Small rooms often need 5,000–15,000 BTU, medium rooms 15,000–25,000 BTU, and larger open areas may require 25,000–30,000 BTU or more.
• Heat Type: Infrared units radiate heat to objects and occupants, providing direct warmth; blue flame (convective) models warm air for distribution throughout the room.

Vented Vs Vent-Free (Ventless)

• Direct Vent (Vented) models draw combustion air from outdoors and vent exhaust, which improves indoor air quality and is often required in bedrooms or tight homes.
• Ventless heaters offer higher efficiency in heat delivery but release combustion products into the living space; they are subject to local codes and oxygen-depletion sensor requirements.

Fuel Type And Conversion

• Check whether a unit is liquid propane ready or set up for natural gas. Many products prohibit fuel conversion; confirm the shipped configuration matches your fuel supply.
• Conversion should only be performed by qualified technicians using manufacturer-approved kits when allowed.

Safety Features

• ODS (Oxygen Depletion Sensor): Required on many ventless appliances to shut off fuel if oxygen drops.
• Safety Pilot And Pressure Regulators: Prevent gas flow if the pilot extinguishes or pressure deviates; common on direct vent models.
• Local Codes: Verify local building and fire codes for venting requirements, allowable ventless use, and required clearances.

Controls And Thermostat

• Thermostat control improves comfort and fuel economy by maintaining set temperatures.
• Variable output or multiple heat settings (High/Medium/Low) allow better matching to changing conditions.

Installation And Mounting

• Wall Mount vs Floor Placement: Consider wall-clearing, height, and surrounding materials for safe clearances.
• Venting Path: Direct vent models require a sealed vent to the outside—plan for routing and exterior termination.
• Professional installation is recommended when venting, gas lines, or conversions are involved to ensure compliance and safety.

Energy Efficiency And Operation

• Vent-free units often deliver higher immediate room heat per BTU because less heat exits through flue gases.
• Infrared heaters may provide perceived warmth with lower air temperature by warming occupants and objects directly.
• Consider insulation, window quality, and room layout when estimating runtime and fuel consumption.

Maintenance And Warranty

• Regular inspection of pilot assemblies, burners, and gas connections is essential for safe operation.
• Refer to manufacturer guidelines for cleaning, storage, and annual service intervals.
• Check warranty coverage for parts and labor, and confirm authorized service channels.

Comparison Perspectives

• Indoor Air Quality Perspective: Direct vent units are preferable where minimizing indoor combustion byproducts is a priority.
• Efficiency Perspective: Ventless and infrared options can feel warmer more quickly and operate without an external vent.
• Installation Complexity: Vent-free models typically require simpler installation; direct vent models need additional venting work.
• Safety/Code Perspective: Local code requirements may eliminate some ventless choices for certain rooms (e.g., bedrooms).
