Mr. Heater MH18CH Radiant Cabinet LP Heater
The Mr. Heater MH18CH is a cabinet-style radiant propane heater designed for ventilated work areas. Its cabinet encloses the tank for a cleaner appearance and more compact footprint.
Features: Hi-med-low regulator for adjustable output, Automatic Low Oxygen Shutoff System (ODS) for safety, and a design that requires no electricity. The three-position regulator enables flexible heat control without additional components.
Ideal uses include garages, workshops, and construction shelters where radiant heat is preferred. The no electricity operation allows continued use during power outages, while the ODS provides an important safety layer in partially enclosed spaces.

Dyna-Glo models typically prioritize larger coverage and simple operation. The piezo ignition removes the need for batteries, and the variable output supports intermittent or sustained use depending on work conditions.
Gasland MHA18BN Propane Radiant Heater
The Gasland MHA18BN is a portable cabinet-style radiant heater that emphasizes mobility and built-in safety. The tank housing and handle/wheel design support easy repositioning across job sites.
Features: Tip-over and low oxygen shutoff systems, no electricity required, rolling wheels and carry handle for portability, and a cabinet that conceals the propane tank. Rated for coverage up to 450 sq.ft in typical conditions.
This model suits users who need a mobile heater to move between spaces and storage when not in use. The internal housing of the tank keeps the footprint tidy and reduces exposed components during transport.
OKF Propane Heater 6K-18K BTU
The OKF cabinet heater provides three power settings and highlights a pulse ignition system, which the manufacturer positions as more durable than traditional piezo igniters.
Features: 6,000/12,000/18,000 BTU settings, pulse ignition, supplied hose and regulator for 20 lb tank connection, ODS and tip-over shutoff, and extended low-setting run time claims (up to 69 hours at 6,000 BTU).
OKF is targeted at users who want a robust ignition method and long runtime at low output. The unit’s multiple safeties make it usable in ventilated indoor environments with an emphasis on unattended runtime scenarios.
Buying Guide: How To Choose A Propane Cabinet Heater
When evaluating propane cabinet heaters, consider these core factors to match a unit to your space and requirements.
Heat Output And Coverage
BTU Rating indicates maximum heat output. Typical cabinet heaters offer 6,000–18,000 BTU. Choose a higher BTU for larger or poorly insulated spaces. Manufacturers’ square-foot coverage estimates vary; treat them as guidelines affected by insulation, ceiling height, and outside temperature.
Ignition Type And Reliability
Common ignition types include piezo, pulse, and continuous pilot. Piezo igniters are simple and battery-free; pulse ignitions claim greater durability. Consider the ignition type if you need frequent starts in cold conditions.
Safety Features
Key safety systems to look for are Automatic Low Oxygen Shutoff (ODS), tip-over shutoff, and flame failure protection. These are critical for semi-enclosed use. Ensure the unit is installed and operated per manufacturer guidelines and local regulations.
Portability And Installation
Cabinet heaters may have internal tank compartments, wheels, or handles. If you plan to move the heater between job sites or store it seasonally, portable design and sturdy casters are important. Check whether a hose and regulator are included for 20 lb tanks.
Fuel Connection And Tank Compatibility
Most cabinet heaters connect to a standard 20 lb propane cylinder using a supplied regulator and hose. Some units support larger tanks or dual connections; verify compatibility if you need extended runtime or remote tank placement.
Run Time And Efficiency
Manufacturers sometimes provide run time estimates at the lowest setting. Use these as approximate values. Longer low-setting runtimes reduce refills but depend on tank size and real-world thermal load.
Intended Use And Ventilation
Propane cabinet heaters produce combustion byproducts that require adequate ventilation. Confirm whether the model is rated for indoor use in ventilated garages or only for outdoor/temporary job site use. Never use in tightly sealed living spaces unless explicitly approved by the manufacturer.
Durability And Build Quality
Look for rugged cabinet construction, protective grilles, and corrosion-resistant coatings if you plan to use the heater in dusty or damp environments. Portable units benefit from concealed tank compartments to protect connections during transport.
Maintenance And Warranty
Regular maintenance items include inspecting hoses, regulators, and igniters, and cleaning the radiant elements and grilles. Check manufacturer warranty terms and availability of replacement parts such as hoses, regulators, and igniter components.
Comparison Perspectives
- Small Space / Short-Term Use: Choose lower BTU models or portable buddy-type units for up to ~225 sq.ft.
- Medium Garages / Workshops: 6,000–18,000 BTU cabinet heaters balance portability and coverage for 300–600 sq.ft.
- Mobility vs. Stationary: Select wheeled cabinet designs if frequent relocation is needed; fixed feet are adequate for semi-permanent placement.
- Runtime Needs: If long low-output runtime is a priority, verify low-BTU run time figures and tank capacity compatibility.
Use this guide and the product summaries above to identify a heater that matches your space size, portability needs, and safety requirements. Always follow manufacturer setup, clearance, and ventilation instructions for safe operation.
