Mr. Heater Propane Unit Heater MHU80LP

Check Price on Amazon

Type: Ceiling/Wall Mounted Propane Unit Heater. Output: 80,000 BTU/h. The manufacturer lists this model as a dedicated propane unit heater designed to warm enclosed workspaces.

Features include a spark ignition with self-diagnostic control module and two angle brackets for straightforward ceiling mounting. The unit is intended for shops that need persistent, distributed heat from a mounted heater rather than a portable blower.

Because it mounts overhead, the MHU80LP is useful where floor space matters. Consider venting requirements, clearances, and a compatible propane supply line during installation. This model is typically chosen for small-to-medium sized workshops needing fixed heating.

Mr. Heater 125,000 BTU Forced Air

Check Price on Amazon

Type: High-Output Forced-Air Propane Heater. Output: 125,000 BTU. Built for larger workshops, construction sites, and situations needing rapid temperature rise.

Key listed features include Quiet Burner Technology claimed to operate up to 50% quieter than standard models, a 10-foot hose and regulator, and a high-temperature limit switch for thermal protection. This model uses a forced-air approach to move heated air quickly through the space.

Forced-air units like this are effective for spaces with higher ceilings or open bays where convective airflow is needed. Plan for safe placement, adequate ventilation, and a secure propane connection when deploying this unit in a shop environment.

Mr. Heater MH60QFAV 60,000 BTU

Check Price on Amazon

Type: Portable Propane Forced-Air Heater. Output Range: 30,000–60,000 BTU. Designed for quieter operation with QBT (Quiet Burner Technology).

Manufacturer features note variable output for runtime control, with the unit running up to 14 hours on a 20 lb tank at low setting. It is categorized as a forced-air model that balances portability and sufficient heating capacity for medium garages.

This unit is often selected where noise reduction matters and when the heater needs to be moved between work areas. Evaluate hose length, regulator compatibility, and any recommended clearance distances before use in an enclosed shop space.

Dyna-Glo 50,000–200,000 BTU Convection

Check Price on Amazon

Type: Liquid Propane Convection Heater. Output Range: 50,000–200,000 BTU. This model covers a broad output range for scaling to workshop size and heating demands.

Manufacturer notes indicate use for both outdoor and indoor construction/commercial spaces provided proper ventilation. Convection heaters move warm air through natural circulation rather than a high-speed blower, which can be advantageous for even warming across large volumes.

Consider the Dyna-Glo when you need flexible output or must heat very large bays. Adequate venting and compliance with local codes for indoor operation are critical when using high-capacity convection heaters in enclosed shops.

Mr. Heater MH540T Tank Top Radiant

Check Price on Amazon

Type: Tank-Top Radiant Propane Heater. Output Levels: 30,000, 36,000, and 45,000 BTU. Designed to mount on a standard 20 lb propane cylinder for localized radiant heat.

Features include 540° radiant coverage through a 360° burner and a 180° swivel bracket. The unit offers tip-over safety shut-off and three heat settings for flexibility in smaller shop zones or outdoor work areas.

Radiant tank-top heaters warm objects and people directly instead of heating all the air, making them effective for workstations or areas where targeted warmth near tools or benches is preferred. Confirm compatibility with tank types and follow recommended safety clearances.

Buying Guide: Choosing A Propane Shop Heater

Selecting the right propane heater for a shop involves assessing space, power, installation, and safety. Below are the key considerations and comparison perspectives to help match a heater to your workspace needs.

1. Heat Output And Coverage

• BTU Rating: Higher BTUs increase heating capacity. Small garages may need 30,000–60,000 BTU; medium shops often require 60,000–125,000 BTU; large bays can exceed 125,000 BTU.
• Coverage Estimates: Use manufacturer coverage numbers as guidance but factor in insulation, ceiling height, and drafts.

2. Heater Type And Air Movement

• Forced-Air Heaters: Provide rapid temperature rise and good air circulation. Best for open bays and quick warm-up scenarios.
• Convection Heaters: Rely on natural air movement for even heating; suitable for larger volume spaces where sustained moderate warmth is needed.
• Radiant Heaters: Heat people and objects directly; efficient for localized workstations and areas where you don’t need to warm all the air.

3. Installation And Mounting

• Portable vs. Mounted: Portable units offer flexibility; mounted units free floor space and offer permanent distribution.
• Venting Requirements: Confirm whether the unit requires venting or is vent-free. High-output units often need venting or fresh-air supply.
• Clearances: Check minimum clearances from combustible materials, ceiling height, and floor for safe operation.

4. Fuel Supply & Hose/Regulator Compatibility

• Tank Size: Runtime depends on tank capacity. Portable models often use a 20 lb cylinder; larger units may connect to a bulk LP supply or require a dedicated line.
• Included Accessories: Note if the unit includes hose, regulator, or conversion kits. Purchasing missing parts adds to installation complexity.

5. Safety Features

• Tip-Over Switches: Important for portable or tank-top models to automatically shut off when knocked over.
• High-Temperature Limit Switches: Prevent overheating by shutting down the burner when internal temperatures exceed safe levels.
• Oxygen Depletion Sensors (ODS): Required for many indoor propane appliances—verify presence and certification for enclosed spaces.

6. Noise, Durability, And Maintenance

• Noise Levels: QBT (Quiet Burner Technology) or similar features reduce operating noise—consider for workshops where concentration matters.
• Durability: Look for rugged housings and corrosion-resistant finishes for shop environments and job sites.
• Maintenance: Routine checks of hoses, regulators, and burner assemblies extend service life; factor in ease of serviceability.

7. Efficiency And Operating Cost Perspectives

• Fuel Consumption: Higher BTU units consume more propane per hour. Compare BTU per hour against runtime on a standard tank for cost estimation.
• Radiant Vs. Convective Efficiency: Radiant units can be more fuel-efficient for focused warmth; convective and forced-air units heat volume more uniformly but may use more fuel.

8. Space-Specific Decision Factors

• Small Workshops: Tank-top radiant or 30,000–60,000 BTU portable forced-air units provide targeted heat without overkill.
• Medium Garages: Ceiling-mounted 80,000 BTU unit heaters or 60,000 BTU portables balance coverage and installation footprint.
• Large Shops/Bays: High-capacity forced-air or convection heaters rated above 100,000 BTU with proper venting and supply infrastructure are more appropriate.

9. Compliance And Code Considerations

• Local Codes: Verify local building and fire codes regarding indoor use of propane appliances, venting, and required clearances.
• Manufacturer Instructions: Follow installation and operation manuals closely; deviations can affect safety and warranty.

10. Comparing Models: Key Trade-Offs

• Portability vs. Permanence: Portable heaters provide flexibility; mounted units provide consistent distribution and free floor space.
• Quick Warm-Up vs. Even Heat: Forced-air delivers fast warm-up; convection yields even temperature over time; radiant focuses on people/objects.
• Noise vs. Performance: Higher output often means more noise; look for quiet-burn technologies if sound is a concern.

When evaluating options, match the heater type to the primary use case: intermittent spot heating, whole-shop continuous heating, or large-area rapid warm-up. Document installation requirements and safety features before purchase to ensure compliant and effective operation in your shop environment.
