Good lighting is a practical companion to any heating solution because well-lit spaces distribute work activities and can reduce perceived cold spots.
Consider pairing adequate lighting with heating to ensure workspace productivity and safety in winter or low-temperature conditions.
Buying Guide: How To Choose A Tube Heater For Your Shop
Selecting the right shop heater means balancing fuel type, heat output, installation, and safety. Below are core considerations and comparison perspectives to guide a purchase that aligns with shop size, utility availability, and operational patterns.
1. Fuel Type And Availability
Gas heaters (natural gas or propane) deliver high BTU output and lower operational cost per unit energy in many areas, but require gas piping, venting, and combustion clearances. Electric heaters avoid venting and combustion but require sufficient electrical service; they can be simpler to install if a 240V circuit is available.
2. Heat Output: BTU And Watt Equivalents
Match heater capacity to shop volume, not just square footage. Use ceiling height to calculate cubic footage. As a rule of thumb, higher ceilings require proportionally more output. Tube heaters like SunStar (45,000 BTU) provide radiant coverage along a linear run; unit heaters like Mr. Heater (80,000 BTU) and electric fan-forced models produce convective airflow to heat air volume.
3. Coverage And Placement
Consider intended coverage area: shop heaters list estimated square footage but verify for your climate and insulation level. Tube heaters distribute radiant heat along their length, which is effective for work zones and ground-level comfort. Ceiling-mounted electric units direct heated air downward; unit heaters often mount to walls or ceilings and use blowers to move warm air.
4. Installation Requirements And Clearances
Review minimum clearance to combustibles, mounting heights (many units specify ≥8 ft), and accessibility for maintenance. Gas appliances require correct venting category and combustion air. Electric hardwired units require appropriate breakers and conduit. Tube heaters may need longer mounting spans and supports for the tube.
5. Controls, Thermostats, And Energy Management
Look for integrated thermostats, remote controls, timers, and ECO modes. Programmability reduces runtime and energy usage for intermittent shop use. Electric units often offer precise electronic control; gas units may require a compatible wall thermostat or controller.
6. Safety Features And Certifications
Prioritize units with recognized safety listings (ETL, UL) and built-in protections like overheat shutoff, tip or flame failure devices, and proper venting safeguards. Verify local building codes and fuel appliance regulations for commercial or shared occupational spaces.
7. Efficiency And Operating Cost
Efficiency ratings (percent for combustion appliances) give an indication of energy delivered to the space. Electric heaters are effectively close to 100% efficient at point-of-use, but electricity costs vary. Gas heaters with higher efficiency reduce fuel consumption but require proper venting and combustion management.
8. Noise, Airflow, And Worker Comfort
Forced-air heaters include blowers which create airflow and noise; tube heaters are often quieter and provide radiant warmth. Consider the noise tolerance of the workspace and whether directed airflow could impact dust or fumes. Radiant units may be preferable for quiet, focused work areas.
9. Durability, Material, And Maintenance
Shop environments benefit from robust construction: steel housings, corrosion-resistant finishes, and serviceable components. Check warranty terms and ease of access for filters, fans, or igniters. Tube heaters with long runs can be easier to maintain if modular replacement parts are available.
10. Venting, Combustion Air, And Indoor Air Quality
Gas-fired equipment must be vented properly to manage combustion byproducts. Some shop heaters use sealed combustion or direct-vent designs to reduce indoor air impacts. Ensure adequate ventilation for pollutants and moisture management, particularly in enclosed shops.
11. Matching Heater Type To Shop Use
- Intermittent Use/Small Bay: Electric ceiling or wall-mounted heaters offer on-demand heat and simple controls.
- Continuous Use/Large Bay: High-BTU gas unit heaters or multiple tube heaters distribute heat more economically at scale.
- Workstation-Focused Heat: Tube heaters or radiant units concentrate warmth at work areas without overheating the entire volume.
12. Installation And Professional Services
For gas systems, hire licensed HVAC professionals for piping and venting. For high-wattage electric units, use licensed electricians to verify circuit capacity and perform hardwiring. Obtain required permits and follow local mechanical codes for safety and insurance compliance.
