Mr. Heater Propane Unit Heater 80,000 BTU/Hr. MHU80LP
This 80,000 BTU propane unit is designed for garage and workshop environments and lists ceiling mount compatibility through supplied angle brackets. The unit is sized to heat up to 1,000 square feet under typical conditions.
Key features include a spark ignition with a self-diagnostic control module for reliable start-up and fault detection. The package includes two angle brackets for mounting flexibility and easier install on overhead structures. Electrical requirements and clearances should be reviewed prior to installation.
For ceiling-mounted installations, confirm minimum clearance from combustible surfaces and follow local building and gas codes. This unit’s design centers on forced-air delivery suited to garages and moderate-sized shops.

Although designated as a natural gas model, this Big Maxx heater includes a liquid propane conversion kit so it can be adapted for LP use where piping or hookups favor propane. The unit is rated at 80,000 BTU and lists coverage up to 2,000 square feet depending on insulation and usage.
Dimensions and electrical specs are provided by the manufacturer. The heater ships with two angle brackets for ceiling or overhead mounting. The product is intended for category 1 vertical or category 3 horizontal venting; installers should verify venting method suitability for ceiling-mounted placement.
Installation guidance notes a minimum 8 ft clearance from floor to base of unit. The unit requires a dedicated gas connection and proper venting for indoor ceiling or suspended installations.
Reznor 60,000 BTU Gas Unit Propane Garage Heater UDXC-60
The Reznor UDXC-60 is specified for propane and indoor garage use, offering two heat output levels to match milder and colder conditions. The unit lists 60,000 BTU with on low and high-stage settings and an 83% thermal efficiency rating.
UDXC models include threaded-nut retainers at four suspension points for ceiling mounting; separate mounting hardware may be required depending on the installation structure. The design emphasizes quiet forced-air operation with a low-static propeller fan suitable for overhead placement.

Because the model is intended for indoor use, installers should follow local codes for gas-fired equipment in garages, confirm combustion air requirements, and ensure proper clearance and safe gas connections for a ceiling-mounted installation.
Reznor 45,000 BTU Unit Natural Gas Heater UDXC-45
The Reznor UDXC-45 is a lower-capacity member of the UDXC series, offering 45,000 BTU with two-stage firing and an 83% thermal efficiency. The heater is designed for indoor garage and shop environments where ceiling suspension is desired.
Four suspension points and threaded-nut retainers accommodate ceiling mounting. The unit is suited for spaces that require moderate heating without oversizing. The two output levels allow for energy-conservative operation on milder days.
Natural gas models may not be directly compatible with propane without a conversion kit; confirm fuel type and conversion options if LP is required. Follow venting, combustion air, and clearance guidelines when installing above workspaces or storage areas.
Dr. Infrared Heater 10,260 BTU / 3000W Carbon Infrared Heater
While electric rather than propane, this carbon infrared unit is included as a ceiling-mountable alternative for garages lacking gas infrastructure. It provides instant, odorless infrared heat and is rated at 3000W (10,260 BTU) with weatherproof IP55 rating for indoor/outdoor use.
The heater ships with mounting hardware for ceiling or wall installation and includes a remote for control. Its plug-and-play nature eliminates gas piping and venting concerns but requires appropriate electrical capacity (220–240V model specified).
Electric overhead heaters offer simpler installation where gas venting, combustion air, or flammable storage constraints complicate propane ceiling installations. Assess electrical panel load and wiring requirements before selecting an electric ceiling unit.
Buying Guide: Selecting A Ceiling-Mounted Propane Garage Heater
Choosing the right overhead heater involves balancing heating capacity, installation constraints, fuel availability, and safety/venting. Use the perspectives below to evaluate options for your garage.
1. Sizing And BTU Requirements
Calculate approximate BTU needs by considering garage volume, insulation level, climate, and desired temperature rise. Ceiling-mounted gas units are commonly available from 45,000 to 80,000 BTU. Oversizing can lead to short cycling; undersizing may not maintain comfort.
2. Fuel Type And Conversion
Confirm whether your garage will use propane (LP) or natural gas. Some models offer LP conversion kits or come factory-configured for one fuel. Conversion may require parts and professional adjustment; check manufacturer guidance.
3. Mounting And Bracket Compatibility
Ceiling-mount compatibility varies: some units include angle brackets or suspension points, while others require separate hardware. Verify mounting points, weight, and ceiling structure to ensure secure overhead installation.
4. Venting, Combustion Air, And Clearances
Gas-fired ceiling heaters need compliance with venting and combustion-air requirements. Check minimum clearances from the unit to floor, walls, and combustibles. For enclosed garages, ensure adequate fresh-air supply or follow sealed-combustion options if available.
5. Efficiency And Two-Stage Operation
Two-stage burners or variable output options (high/low fire) offer better efficiency and comfort control, especially for fluctuating outdoor temperatures. Higher thermal efficiency ratings indicate more heat delivered to the space for given fuel input.
6. Noise, Air Distribution, And Fan Type
Forced-air units with propeller fans distribute heat quickly but can generate fan noise. Look for low static or quiet fan designs if noise is a concern. Consider adjustable louvers or directional vents for targeted heat delivery from overhead mounts.
7. Electrical And Control Features
Many gas unit heaters require a small electrical supply for ignition and controls. Confirm voltage and amp draw. Thermostat compatibility, built-in diagnostics, or remote control features can improve operation and maintenance.
8. Safety Features And Certifications
Confirm that the unit has required safety features such as overheat protection, flame failure/device, and certified listings for indoor gas-fired equipment. Follow manufacturer and local code requirements for installation by qualified personnel.
9. Installation Complexity And Professional Services
Gas ceiling heaters often require licensed HVAC or gas professionals for safe installation, including gas piping, venting, and combustion-air provisions. Electric ceiling heaters may reduce complexity but require appropriate electrical work.
10. Alternative Solutions And Hybrid Approaches
If propane piping or venting is impractical, consider electric infrared or forced-air electric ceiling heaters as alternatives. Hybrid approaches can pair a gas unit with supplemental electric heat for zoning or rapid warm-up in specific areas.
