Buying Guide: How To Choose The Right Shop Tube Heater Or Garage Heater

Selecting the appropriate heater for a workshop involves balancing heating performance, installation complexity, operational cost, and safety. Below are the primary factors to compare and verify before purchase.

1. Heating Type And Heat Distribution

• Tube Heaters (Infrared/Radiant) — Deliver radiant heat along a linear element. Effective for targeted work areas and vehicle bays where radiant warmth is preferred over heating all air volume.
• Unit Heaters — Combine combustion or electric elements with a fan to distribute convective heat. Suitable for rapidly warming larger volumes.
• Electric Fan-Forced Heaters — Provide fast convective heat without combustion products; they require adequate electrical capacity.

2. Fuel Source And Operating Cost

• Natural Gas / Propane — Often lower operational cost in many areas and higher BTU outputs per unit; requires gas lines and venting considerations and combustion clearances.
• Electric — Cleaner installation (no venting) but operating cost depends on local electricity rates and may require significant circuit capacity for high-wattage units.

3. Installation And Mounting

• Check minimum clearances from the floor, walls, and combustible materials as specified by the manufacturer.
• Ceiling-mounted tube heaters require secure rafters or joists and may need brackets to span joist spacing; unit heaters may need wall brackets or ceiling supports.
• Hardwiring versus plug-in: many high-capacity electric units require 240V hardwiring and a dedicated breaker.

4. Coverage Area And BTU/Watt Capacity

• Estimate the shop’s cubic volume (sq. ft. x ceiling height) and consider insulation level. Higher ceilings mean more heat loss; radiant heaters can be more efficient for spot heating.
• Compare BTU ratings for gas models and watt ratings for electric models; convert as needed (1 watt ≈ 3.412 BTU) to evaluate equivalent outputs.

5. Control Features And Thermostat Options

• Look for built-in thermostats, remote control, programmable timers, and ECO modes to manage runtime and reduce energy consumption.
• Compatibility with external thermostats or building control systems can be important in larger shops.

6. Venting, Combustion Air, And Safety

• Gas-fired heaters require correct venting category per installation (e.g., Category 1 vs Category 3), proper combustion air supply, and adherence to local codes.
• Electric heaters eliminate combustion concerns but still require overheat protection, thermal cutouts, and proper electrical protection.
• Consider installing CO monitoring and smoke detection where gas combustion is present.

7. Durability, Warranty, And Certification

• Prefer units with robust metal construction for workshop environments where debris and impacts are possible.
• Verify UL/ETL listings and manufacturer warranty terms for commercial or heavy-duty usage.

8. Noise And Air Movement

• Fan-forced heaters generate air movement and noise. If quiet operation is important for certain tasks, consider radiant tube heaters or lower-speed fan units.
• Evaluate louver adjustability and plume direction to avoid blowing dust across sensitive work surfaces.

9. Electrical Service And Panel Capacity

• High-wattage electric options require the correct circuit breaker size, wiring gauge, and often 240V service. Confirm available electrical capacity before ordering.
• Consider staged or multi-unit installations to distribute electrical load.

10. Layout And Zoning Strategies

• Large shops benefit from zoning: use tube or radiant heaters to warm specific bays or workstations and maintain lower ambient temperature elsewhere to reduce costs.
• Combining systems (e.g., a gas unit heater for bulk heating and radiant tubes for spot warming) can optimize comfort and efficiency.

Comparison Perspectives

• Cost-Per-BTU Perspective — Gas systems typically provide more BTU per dollar of fuel in many regions; calculate local utility rates for accurate comparisons.
• Installation Complexity Perspective — Electric heaters have simpler installation when adequate electrical service exists; gas systems need venting and gas piping.
• Maintenance Perspective — Gas combustion systems require periodic inspection for venting and burner performance; electric systems generally need less routine combustion-related maintenance.
• Operational Flexibility Perspective — Radiant tube heaters provide precise spot heating; fan-forced units change room air temperature faster.

When evaluating a specific model, cross-check manufacturer-specified clearances, installation manuals, certification marks, and local code requirements. For mixed-use or commercial shops, consult a licensed HVAC or mechanical contractor to size equipment and plan safe installation and venting.
