NewAir Portable Garage Heater
The NewAir NGH160GA00 is an electric ceramic heater designed for small garages and workshops. It advertises coverage up to 160 square feet and pairs a ceramic heating plate with a 200 CFM fan to circulate warm air quickly.
- Safety Features: Cool-to-the-touch exterior, internal thermostat, and automatic shut-off to prevent overheating.
- Portability: Built-in carry handle, tilting head for directed heat, and two heat modes for flexible use.
- Performance: Ceramic element provides steady heat with relatively low noise compared with forced-air gas units.
This unit suits enclosed, ventilated garages or small workshop spaces where electric power is available and flame-free heating is preferred for safety or indoor use.
Mr. Heater Portable Buddy MH9BX
The Mr. Heater MH9BX Portable Buddy is a compact propane radiant heater with adjustable output between 4,000 and 9,000 BTU. It’s rated for spaces up to about 225 sq. ft. and focuses heat directly on people and objects rather than heating all the air.

- Radiant Heat: Infrared-like heating warms surfaces and occupants quickly, useful when spot heating a workbench or corner.
- Safety: Improved tip-over safety switch with audible engagement and built-in features that reduce risk when used per instructions.
- Ignition: Piezo igniter allows matchless start-up; no batteries required.
Because it’s propane-based, this heater is best for workshops and garages with adequate ventilation and where a portable fuel source is acceptable. It provides immediate, localized warmth without requiring electrical connections.
Remington 1500W Electric Heater
The Remington REM-222A-120 is a heavy-duty electric forced-air heater designed for quick heat in small to mid-size workspaces. It claims coverage up to 165 square feet with two heat settings and an adjustable thermostat.
- Fast Warm-Up: Heats up in seconds to circulate hot air around a bench area or small room.
- Control: Two heat settings and an adjustable thermostat let you match output to the work environment.
- Use Case: Suited to jobsites with reliable power where instant air warming and modest portability are priorities.
Electric forced-air models like this are clean and simple to operate indoors where propane or diesel are not desired. They require appropriate circuit capacity for sustained operation at 1500W.
Mr. Heater MH60QFAV Propane Forced Air
The Mr. Heater MH60QFAV is a high-output propane forced-air heater offering up to 60,000 BTU with variable output from 30,000 to 60,000 BTU. It uses QBT technology to run quieter than many similar forced-air units.

- High Capacity: Suitable for larger garages, shops, or job sites requiring powerful airflow and rapid temperature rise.
- Variable Output: Adjustable BTU lets you scale fuel consumption and heat delivery to conditions.
- Operational Notes: Forced-air propane units push warm air quickly but require safe ventilation and fuel management.
This model is aimed at users needing robust, portable heat for larger or drafty spaces where electric heaters would be undersized.
LF Bros 5KW Diesel All-In-One Heater
The LF Bros 5KW diesel heater is an all-in-one air heater4,700–17,000 BTU (as listed in metric conversion) and targets vehicle, RV, and shop applications where mains power may be limited.
- Fuel Versatility: Runs on diesel and supports 12V/24V electrical systems, plus 110V with the included transformer.
- Controls & Convenience: Remote control and LCD display with pre-paired remote simplify setup and daily use.
- Range: Designed for colder operating temperatures and extended runtimes with low fuel consumption rates.
Diesel heaters like this work well for detached workshops, garages, and mobile setups where diesel is available and a self-contained heating solution is preferred over external fuel cylinders or pure-electric options.
Buying Guide: Choosing The Right Portable Shop Heater
Selecting a heater for a shop or garage depends on multiple factors. Below are the key considerations to compare models from electric ceramic to high-BTU propane and diesel units.
Space Size And Heat Output
Estimate the cubic feet of your workspace (length × width × height). For moderately insulated garages, electric 1500W heaters or small propane radiant units suffice for localized warming up to roughly 150–250 sq. ft. Larger or poorly insulated spaces require higher BTU forced-air or diesel heaters.
Fuel Type And Availability
- Electric Heaters: Clean, easy indoor use, no combustion byproducts. Limited by electrical capacity and heating power.
- Propane Heaters: Portable and powerful; radiant models heat people/objects directly, forced-air models move warm air quickly. Require ventilation and safe cylinder handling.
- Diesel Heaters: Self-contained and efficient for mobile or off-grid use; require fuel supply and proper exhaust management for combustion models.
Safety Features
Key safety elements to compare: tip-over protection, overheat shutoff, cool-to-touch housing, and for combustion units, reliable ignition and flame/CO safeguards. Always follow manufacturer ventilation recommendations for propane/diesel heaters.
Portability And Placement
Consider weight, handle design, and whether the unit can be tilted or mounted. Radiant heaters are ideal for spot heating; forced-air heaters move heat across larger zones but may require placement that avoids obstructions to airflow.
Noise Level
Forced-air and high-BTU units create more noise than ceramic or radiant heaters. If noise is a consideration in a small shop, look for quieter models or units with noise-reduction technology.
Thermostat And Controls
Adjustable thermostats, timers, and remote controls improve efficiency and comfort management. Precision temperature control helps maintain a steady shop environment and reduce fuel or electricity consumption.
Durability And Duty Cycle
Shop environments often require robust construction and continuous operation capability. Look for models rated for jobsite use or with metal housings and reliable fans/ignition systems designed for extended runtimes.
Installation And Ventilation Needs
Electric heaters are plug-and-play. Propane and diesel units may need secure cylinder placement or exhaust routing. Ensure adequate ventilation for combustion heaters to prevent buildup of fumes.
Maintenance And Serviceability
Check filter and fan access, replacement part availability, and ease of cleaning. Diesel heaters may need periodic burner and fuel system service; propane units require inspection of hoses and fittings.
Comparison Perspectives
- Small, Indoor Shops — Electric ceramic or small forced-air 1500W units offer safe, clean heat with plug-in convenience.
- Spot Heating Workbenches — Propane radiant heaters warm people and tools quickly without heating the entire bay.
- Large Or Drafty Spaces — High-BTU forced-air propane heaters or diesel units deliver sufficient output to raise ambient temperature quickly.
- Mobile Or Off-Grid Use — Diesel all-in-one heaters with 12/24V support are suitable for RVs, trailers, or detached shops without reliable mains power.
Use these factors to match the heater’s type, capacity, and features to your workspace size and operational needs. Prioritize safety features and follow manufacturer guidance for ventilation and placement when using combustion-based portable heaters.
