Rinnai EX22DTWN Direct Vent Wall Furnace
This Rinnai model is a direct vent wall furnace designed for indoor natural gas use with 21,500 BTU output. It employs modulating technology to match heat output to demand, which helps minimize temperature swings and reduce fuel consumption. The unit features a cool-to-the-touch cabinet and self-diagnostic electronics for safety and troubleshooting. As a direct vent system, it draws combustion air from outdoors and vents exhaust directly outside, reducing indoor combustion byproducts and improving indoor air quality.
Installation requires proper venting and gas hookup per local codes. The unit is positioned for wall-mount use and fits spaces that need steady, zone-specific heating. Users should confirm fuel compatibility and ventilation routing before purchase.
Comfort Glow 11,000 BTU Direct Vent Propane
The Comfort Glow 11,000 BTU model is a vented propane wall heater rated to heat up to approximately 375 sq. ft. It uses a sealed burn system with Matchless Piezo Ignition and a safety pilot with a built-in pressure regulator to stop gas flow if the pilot goes out. The compact footprint (20 H, 17 W, 7 D inches) makes it suitable for medium rooms and applications where space is limited.

As a direct vent appliance, it vents combustion byproducts outdoors and is intended for locations where propane is the available fuel. Confirm orientation, clearances, and vent termination placement for safe and code-compliant installation.
Comfort Glow 17,000 BTU Direct Vent Propane
This larger Comfort Glow propane model offers 17,000 BTU for coverage up to about 570 sq. ft. It retains the brand’s sealed burn design, Matchless Piezo Ignition, and safety pilot with a pressure regulator. The dimensions (20 H, 27.3 W, 6.5 D inches) make it a wider unit for larger rooms or open-plan spaces.
Because it’s a direct vent heater, combustion air and exhaust are isolated from the living space. This model works where a propane supply is present and direct vent routing to the exterior is feasible. Confirm BTU needs for your room size and local code requirements for propane appliances.
Comfort Glow 25,000 BTU Direct Vent Natural Gas
The Comfort Glow 25,000 BTU unit is the largest in this set, rated for coverage up to around 825 sq. ft. It uses a sealed burn system with Matchless Piezo Ignition and a safety pilot with a pressure regulator to stop gas flow if needed. Its larger cabinet (26.5 H, 32.25 W, 8.75 D inches) supports high output for bigger rooms or combined spaces.

This model is for natural gas supply environments and requires through-wall or direct vent termination outdoors. It’s appropriate where higher BTU capacity is needed without central HVAC modifications. Verify venting route, clearances, and gas line capacity when planning installation.
EMPIRE DV215 NG 15,000 BTU Direct Vent
The EMPIRE DV215 provides 15,000 BTU of natural gas heat in a direct vent wall furnace format. The unit dimensions (20 1/4″ W x 9 3/8″ D x 24 7/8″ H) make it a mid-size option designed for zonal heating. The unit ships with venting components and a vent cap to support typical through-wall installations.
As a direct vent system, it draws combustion air from outdoors and exhausts outside, reducing indoor combustion exposure. This model is an option for rooms where moderate heating output is required and a natural gas line is available. Check local venting regulations and required clearances before installation.
Buying Guide: How To Choose A Vented Wall Heater
Selecting the right vented wall heater requires matching the heater’s features to your room size, fuel availability, installation constraints, and safety expectations. Below are the key factors to compare.
Venting Type And Indoor Air Quality
Direct Vent heaters draw combustion air from outside and exhaust directly outdoors. This reduces indoor combustion byproducts and is typically preferred for bedrooms and living spaces. Vent-free
Fuel Type: Natural Gas Vs. Propane
Choose based on available supply: Natural gaspropane (LP)
BTU Output And Room Size
Match BTU to room area. General estimates: 10,000–15,000 BTU for small-to-medium rooms, 17,000–25,000+ BTU for larger spaces. Consider insulation, ceiling height, and open-plan layouts. Oversizing wastes fuel; undersizing leaves spaces cold.
Safety Features
Key safety features include sealed burn systems, automatic pilot shutoff/pressure regulators, cool-touch cabinets, and self-diagnostic electronics. For propane, confirm ODS (Oxygen Depletion Sensor) presence when applicable, and follow ventilation requirements.
Installation Requirements
Direct vent units require a clear path for the vent to the exterior, proper clearances, and a gas line sized for the BTU load. Many local codes require professional installation and permits. Confirm vent cap placement, wall thickness compatibility, and whether venting components are included.
Energy Efficiency And Controls
Modulating burners and thermostatic control allow heaters to match output to demand, reducing fuel consumption and temperature swings. Check whether the unit supports room thermostats, built-in thermostats, or simple manual control. Self-diagnostics can simplify servicing.
Noise And Heat Distribution
Many vented wall heaters use convection heating, which is quiet and distributes heat gradually. Some units include fans for faster circulation; fan noise and power requirements should be considered for bedrooms or quiet spaces.
Maintenance And Durability
Periodic inspections of venting, pilot assembly, and gas connections are essential. Models with accessible components and clear diagnostic codes make servicing easier. Look for manufacturer support and replacement parts availability.
Space And Aesthetics
Wall-mounted units vary in size and grille design. Confirm physical dimensions and orientation for the mounting location. Larger BTU units will have larger cabinets and may affect wall use or decor.
Code, Warranty, And Local Restrictions
Check local building codes for permitted venting types and room restrictions. Some jurisdictions restrict vent-free appliances. Review manufacturer warranties and registration processes for coverage details.
Comparative Perspectives
- High Efficiency / Modulating Output: Choose models with modulating burners and self-diagnostics for steady comfort and fuel savings.
- Small Rooms / Condensed Footprint: Lower-BTU, compact units fit smaller rooms and tight wall spaces.
- Large Spaces: Higher-BTU direct vent heaters provide coverage for open or combined areas but require larger venting and gas capacity.
- Propane Vs. Natural Gas: Select the fuel type your home supports and confirm conversion is not required unless specified.
Before purchasing, measure your target room, confirm fuel availability, review local venting codes, and plan for professional installation where required. Following these considerations will help match the best vented wall heater to your home’s needs.
