The MH18CH Is a cabinet-style radiant LP heater with a H i-Med-Low regulator and an automatic low-oxygen shutoff system. The listing highlights that the unit requires no electricity, making it suitable for locations where power is unavailable or unreliable.
As a radiant cabinet heater, it distributes heat via infrared tiles and offers multiple output settings for flexibility. The enclosed design is intended for indoor-safe supplemental heating when installed and used per ventilation guidelines.
Use cases: supplemental heat for larger small rooms, garages, and additions where a cabinet-style unit is preferred to freestanding radiant heaters.
GasSaf 6 Feet Low Pressure Propane Regulator With CSA Certified LPG Hose
This item Is an accessory but important for many small LP heater setups. The listed features include a QCC1/Type 1 connection compatible with most LP tanks and appliances, a 6-foot low-pressure hose, and a maximum capacity claim up to 95,000 BTU/hr for supported appliances.
The product listing notes broad compatibility across brands and many grill/heater models, and that the flare fitting follows standard 3/8-inch dimensions. It is CSA certified per the listing, which addresses regulatory safety expectations for regulator/hose assemblies.
Use cases: replacing or extending the hose/regulator between a cylinder and a small LP heater, or enabling connection to larger tanks for extended runtime. Verify compatibility with your heater model and local codes.
Buying Guide: How To Choose A Small LP Heater
Selecting the right small LP heater requires comparing performance, safety, installation needs, and intended use. Below are objective factors to evaluate and how they differ across models.
Tips for Getting the Best HVAC Prices
- Prioritize Quality Over Cost
The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - Compare Multiple Quotes

Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
Heat Output And Coverage
- BTU Rating: Match the heater’s BTU to the size and insulation of the space. Small radiant units often start around 4,000 BTU for close-range or small rooms; cabinet heaters can go to 18,000 BTU for larger garages.
- Radiant vs. Convection: Radiant heaters (infrared) warm people and objects directly and are efficient for spot heating. Convection-style or cabinet units warm air and are better for larger volumes.
Portability And Installation
- Portable Models: Look for handles, wheels, and compact footprints if you plan to move the heater frequently (camping, job sites).
- Mounting Options: Some units offer wall-mount or cabinet placement; verify clearance and mounting hardware requirements.
- Fuel Connection: Pay attention to hose length and regulator type. Accessories like a 6-foot CSA-certified hose can enable use with remote tanks for longer runtime.
Safety Features
- Tip-Over Shutoff: Critical for portable units that may be knocked over; ensures automatic shutdown.
- Low-Oxygen/Shutoff Sensors: Required for indoor-safe heaters to prevent CO/oxygen depletion risks in enclosed spaces.
- Ignition Safety: Piezo igniters provide match-free starts and reduce the need for batteries or external flames.
Fuel Supply And Runtime
- Cylinder Size: Standard 20 lb tanks are common, but some models support connection to larger tanks (40 lb or bulk) using appropriate hoses and fittings.
- Regulator Compatibility: Confirm the heater’s regulator requirements and whether the included hose/regulator matches your tank valve type (QCC1/Type1).
Indoor Use Considerations
- Ventilation: Even indoor-safe LP heaters require proper ventilation. Check manufacturer guidance on room size and ventilation before indoor operation.
- Code Compliance: Some jurisdictions restrict or regulate fuel-burning appliances indoors; consult local codes and manufacturer documentation.
Noise, Maintenance, And Durability
- Noise Level: Cabinet heaters with fans can be quieter, while some radiant units may emit operational sounds. Verify listed noise characteristics if quiet operation matters.
- Maintenance: Periodic inspection of hoses, fittings, and ignition components is standard. Replace regulator/hose assemblies per manufacturer recommendations or if damaged.
- Build Quality: Look for sturdy cabinets, corrosion-resistant finishes, and quality regulator/hose materials for longer life in outdoor or job-site conditions.
Comparison Perspectives
- Best For Small Spot Heat: Compact radiant models with 4,000–9,000 BTU ratings give efficient, direct warmth for one or two people.
- Best For Larger Unfinished Spaces: Cabinet or higher-output portable models (around 18,000 BTU) better serve garages and workshops.
- Best For Mobility: Units with wheels, handles, and enclosed tanks provide easier transport and tidier appearance on site.
- Accessory Needs: If you plan extended runtime from larger tanks, choose a CSA-certified regulator/hose compatible with your heater’s fittings.
Checklist Before Purchase
- Confirm intended use (indoor, outdoor, ventilated indoor) and match the heater’s certification for that use.
- Measure the area to be heated and select a BTU range appropriate for peak cold conditions.
- Verify regulator/hose compatibility and whether an accessory hose is required for larger tanks.
- Review safety features like tip-over, low-oxygen shutoff, and reliable ignition methods.
- Check manufacturer installation and clearance specifications to ensure code compliance and safe placement.
