Reznor UDXC-60 Natural Gas Hanging Heater
The Reznor UDXC-60 is a ceiling-mount indoor gas heater designed for garages, workshops, and light industrial spaces. It offers a top rating of 60,000 BTU with two selectable output levels—low fire (34,860 BTU) and high fire (49,800 BTU)—and an 83% thermal efficiency rating. The unit uses a quiet forced-air system with a low static propeller fan intended to minimize noise while moving heated air.
Mounting points include threaded-nut retainers at four suspension locations for hanging installation; brackets or hardware are sold separately. The Reznor design suits enclosed indoor spaces where venting and combustion-air requirements are met by a qualified installer. The product listing emphasizes use in commercial and residential settings and highlights the unit’s performance across variable temperatures.
Reznor UDXC-60 Propane Hanging Heater
This Reznor UDXC-60 variant is configured for propane (LP) fuel while maintaining the same core characteristics as the natural gas model. Rated for 60,000 BTU with two heat output levels, it is suitable for hanging installation in indoor commercial or residential spaces where propane is the available fuel source.

Like the natural gas version, the propane model includes the same suspension points for ceiling mounting and emphasizes quiet forced-air operation. Thermal efficiency and multi-level output make it adaptable for milder or colder conditions, but proper LP hookups and local code compliance are required. The product is positioned for shops, warehouses, and garages needing steady, direct warm-air delivery.
Mr. Heater Big Maxx MHU80NG Hanging Unit
The Mr. Heater Big Maxx MHU80NG is an 80,000 BTU natural gas unit heater designed to cover large spaces such as garages and small warehouses. The package includes two angle brackets for mounting and a natural gas configuration; conversion kit to propane is provided in some purchases per listing details.
Measured performance lists a coverage area up to about 2,000 sq. ft. The heater operates at standard 120 V, drawing low amperage. The unit’s clearance requirements and venting classifications (Category 1 vertical, Category 3 horizontal venting) are specified, which makes proper installation and adherence to building codes essential. The Big Maxx is marketed for robust airflow and high-output heating where ceiling or bracket mounting is desired.
SunPak S34 Hanging Patio Heater
The SunPak S34 is a 34,000 BTU hanging patio heater built for outdoor use, featuring an aluminized black finish. Designed to be suspended over seating areas, it focuses on direct radiant heat rather than forced-air circulation, which is typical for outdoor patio applications.

Because this model is intended for outdoor hanging use, it differs from enclosed-shop heaters in installation and safety requirements. The SunPak’s lower BTU rating compared to industrial units makes it suitable for patios and covered outdoor spaces where localized radiant warmth is preferred. The product listing highlights finish and outdoor suitability rather than extensive indoor venting specifications.
ALORAIR HydroX H100A Hydronic Hanging Heater
The ALORAIR HydroX H100A is a hydronic (water-to-air) hanging heater that integrates with external water heat sources such as outdoor wood boilers and hydronic systems. It features heavy-duty galvanized steel construction, corrosion-resistant copper piping, and a reusable air filter for longevity and maintenance ease.
Key operational points include automatic temperature-controlled fan activation, a centrifugal blower delivering up to 1000 CFM at about 60 dBA, adjustable louvers for directional airflow, and a remote control panel. The unit is aimed at workshops and warehouses where a hydronic heat source is available and where electric or gas-free operation is preferred for the blower and controls. ALORAIR provides a commercial warranty and emphasizes industrial durability.
Buying Guide For Hanging Gas Heaters
Selecting the right hanging gas heater depends on space characteristics, fuel availability, and safety considerations. Below are key decision points to evaluate before purchase and installation.
1. Fuel Type And Availability
- Natural Gas vs. Propane: Choose natural gas if a municipal supply and meter exist; choose propane where line gas is unavailable. Some units are factory-configured for one fuel and may require conversion kits.
- Hydronic Options: Water-to-air units like ALORAIR are alternatives when a hydronic heat source exists; they avoid in-room combustion but require plumbing and a heat source.
2. BTU Output And Space Size
- Match BTU To Volume: Estimate cubic footage and desired temperature rise. Higher BTU models (60k–100k) suit garages, workshops, and warehouses; lower-output units (30k–34k) are more appropriate for patios and small covered spaces.
- Air Movement vs. Radiant Heat: Forced-air unit heaters distribute warmed air quickly; radiant patio heaters warm surfaces and people directly, which can be more efficient outdoors.
3. Mounting And Clearance
- Ceiling Hanging Points: Check for dedicated suspension points and whether mounting hardware is included. Some models list threaded retainers; others require brackets.
- Clearance Requirements: Respect manufacturer-specified clearances from combustibles and floor clearance. Indoor unit heaters often require larger clearances than outdoor patio units.
4. Efficiency, Noise, And Airflow
- Thermal Efficiency: Look for efficiency ratings; higher efficiency reduces fuel consumption per unit of heat delivered.
- Noise Levels: Consider fan type—propeller fans may be quieter for shop use, while centrifugal blowers may provide stronger airflow with moderate noise.
- Air Delivery: CFM ratings indicate how much air a unit moves; higher CFM speeds heat distribution in large spaces.
5. Installation, Venting, And Code Compliance
- Professional Installation: Gas and venting connections typically require licensed technicians and must follow local codes.
- Venting Type: Some units require specific venting categories (for example Category 1 or 3). Patio radiant units may be open-flame but designed for outdoor use only.
6. Controls, Safety Features, And Maintenance
- Control Options: Thermostats, remote controls, and automatic fan activation improve convenience and efficiency.
- Safety Sensors: Look for oxygen depletion sensors, automatic shut-off, and certified safety listings for indoor units.
- Maintenance: Reusable filters, accessible components, and clear service guidelines simplify upkeep and prolong service life.
7. Intended Use: Indoor vs Outdoor
- Indoor Enclosed Spaces: Choose units designed and rated for indoor use with appropriate venting and combustion air provisions.
- Outdoor Or Patios: Select models rated for outdoor hanging or patio use; these often rely on radiant heat and are not suitable for enclosed spaces.
8. Comparison Perspectives
- Performance vs. Installation Complexity: High-BTU indoor heaters deliver robust warming but increase venting and clearance demands. Hydronic units reduce indoor combustion concerns but require integration with a water heat source.
- Initial Cost vs. Operating Efficiency: Higher-efficiency units may cost more upfront but use less fuel over time; consider expected run hours and local fuel costs when evaluating value.
- Noise vs. Air Movement: Quiet units are preferable in noise-sensitive settings; units with higher airflow improve heat spread in large or drafty spaces.
When choosing a hanging gas heater, weigh fuel availability, BTU needs, installation requirements, and intended environment. Use manufacturer documentation and local code guidelines to confirm suitability and safe installation. For indoor gas-fired units, engage a licensed professional to install, commission, and verify venting and safety systems.
