Buying Guide: How To Choose The Right LP Tube Heater

This guide covers key considerations when selecting an LP (propane) tube heater for garages, patios, and outdoor spaces. Evaluate fuel, output, installation, safety, and long-term maintenance to match heater performance to your needs.

1. Heater Type And Intended Use

Garage/Workshop Tube Heaters: Typically mounted to ceilings or walls and use forced-air or radiant tube designs suited for semi-enclosed spaces. Choose units designed for enclosed workspaces and confirm clearance and ventilation needs.

Pyramid/Glass Tube Patio Heaters: Freestanding vertical units that provide radiant heat and ambiance. Best for open-air patios and gatherings; wind can reduce effectiveness.

Portable LP Heaters: Lightweight units for temporary heating. Good for flexibility but generally lower maximum and less even coverage than mounted tube heaters.

2. BTU Output And Coverage

Match BTU To Space Size: Higher BTU generally equals larger coverage, but efficiency, reflector design, and placement matter. For example, 40,000–48,000 BTU pyramid heaters warm group seating, while 45,000 BTU garage tube heaters aim at enclosed spaces.

Consider Heat Distribution: Radiant heaters focus on people and objects rather than heating all air, which is efficient for outdoor or drafty areas. Forced-air tube heaters warm incoming air and are better for enclosed spaces.

3. Fuel Supply And Runtime

Tank Size: Most patio heaters use 20 lb propane tanks. Portable and larger permanent setups may connect to bulk tanks; check compatibility and fittings.

Run Time Estimates: Manufacturer runtimes vary by BTU and control setting. Higher BTU reduces runtime for a given tank size; consider dual-tank or larger tank options for longer events or continuous use.

4. Installation And Clearance

Mounting Height: Tube heaters may require minimum mounting heights (SunStar lists installation as low as 8 ft). Always follow manufacturer clearances from combustibles and local building codes.

Permanent Gas Lines vs. Portable Tanks: Decide if you prefer a permanent gas line hookup or portable tank access. Permanent lines often require professional installation but reduce tank changes.

5. Safety Features And Certification

Required Protections: Look for tip-over shutoff, thermocouples, flame sensors, and CSA or other safety certifications. Proper flame sensing reduces gas leak risk on outdoor heaters.

Ventilation & Carbon Monoxide: For partially enclosed spaces, ensure adequate ventilation. LP combustion produces CO; avoid using outdoor-rated heaters indoors unless explicitly approved.

6. Materials, Durability, And Weather Resistance

Stainless Steel & Coatings: Corrosion-resistant materials increase lifespan in outdoor environments. Glass tube elements require careful handling and may be more fragile than metal burners.

Wind Sensitivity: Exposed flame heaters perform best with wind shielding. Consider the typical wind exposure of your location when choosing an open-flame design.

7. Controls, Adjustability, And Mobility

Variable Heat Settings: Units with adjustable valves allow fine-tuned comfort and fuel conservation.

Mobility: Wheels and handles make repositioning easier for freestanding units. Permanent tube heaters will be fixed but may offer better targeted coverage for defined spaces.

8. Maintenance, Parts, And Repairability

Availability Of Replacement Parts: Check that burners, thermocouples, and orifice kits are available (MENSI and pilot assemblies are examples). Readily available parts reduce downtime.

Serviceability: Units with accessible access panels and standard fittings simplify maintenance. Regular inspections of hoses, connections, and flame appearance improve safety and efficiency.

9. Efficiency And Operating Costs

Efficiency Ratings: Manufacturers may list efficiency percentages; higher efficiency can reduce fuel use. Compare output per BTU and consider effective coverage rather than only raw BTU numbers.

Cost Considerations: Evaluate initial cost, installation, and ongoing propane usage. Higher-output heaters often cost more to operate but may reduce the need for multiple units.

10. Comparison Perspectives

Performance vs. Portability: Mounted tube heaters like the SunStar provide consistent heating for enclosed spaces but are permanent. Portable units like Mr Heater offer flexibility but may not deliver uniform coverage.

Aesthetics vs. Durability: Glass tube and pyramid designs provide visible flames and ambiance at the expense of more delicate components. Stainless steel and metal tube heaters emphasize durability for frequent use.

Repairability vs. Replacement: Opt for heaters with common fittings and available replacement parts if long-term serviceability is a priority. Replacement burner kits and pilot assemblies extend service life without full unit replacement.

When selecting an LP tube heater, weigh the intended environment, total coverage needs, installation constraints, and available maintenance options. Safety certifications and proper installation are essential for reliable operation.
