Radiant Tube Heater FAQ (Frequently Asked Questions)
Introduction
Welcome to our Radiant Tube Heater FAQ (Frequently Asked Questions)! In this post, we’ll answer the most common questions about radiant tube heaters, covering how they work, their benefits, and how to choose the right one for your space. Whether you’re considering a heater for a large warehouse, garage, or outdoor setting, this guide will provide you with the essential information to make an informed decision.
What is a Radiant Tube Heater?
A heating system that uses gas (natural gas or propane) burners to produce infrared radiant heat. The radiant beams heat objects and people directly, rather than heating the air. This method is similar to how the sun warms the Earth. Radiant Heat is essential to a Radiant Tube Heater!
How does a Radiant Tube Heater work?
The system consists of a burner control box, radiant emitter tubes, and a reflector assembly. The gas burner heats the emitter tubes, which then emit infrared radiant heat. The reflector directs radiant energy toward the heated area, warming objects and surfaces in its path.
What are the benefits of a Radiant Tube Heater?
Energy Efficiency: Radiant heating can save 20-50% on fuel consumption compared to forced air systems.
See this blog post for more info on the incredibly savings achieved through radiant heating efficiency: Infrared Radiant Heat vs Forced Air Heat
Comfort: It provides even heating and reduces drafts.
Quick Warm-Up: Radiant heat warms objects and people directly, leading to faster comfort levels. Especially true when using 2-stage technology such as in our HL3 Series.
Reduced Heat Loss:This system reduces heat loss by heating objects instead of air, so less heat escapes when doors open.
Where can Radiant Tube Heater be used?
These heaters are ideal for large, open spaces such as warehouses, garages, workshops, and industrial buildings. People also use them in outdoor settings like patios and sports arenas.
Are there different types of Gas Radiant Heaters other than Radiant Tube Heaters?
Yes, there are two main types:
High-Intensity Heaters: These heaters produce an open flame and are commonly used for spot heating in areas with high ceilings. They’re also known as Ceramic Heaters or Flat Panel Heaters.

Low-Intensity Heaters: Radiant Tube Heaters are in this category. These have an enclosed flame and are more commonly used for general space heating.

Are Radiant Tube Heaters safe?
Yes, when installed and maintained properly, they are safe. A professional should install them to ensure they meet all safety standards and regulations. Check out this blog post to learn more: Are Infrared Radiant Heaters Safe?
How do I choose the right gas Radiant Tube Heater for my space?
Consider factors such as the size of the area, ceiling height, insulation quality, and specific heating needs. Use a Heat Loss Calculator (we can do this for you) to determine the exact BTU requirements for your space.
Can you use Gas Radiant Tube Heaters in residential settings?
How do I maintain a Radiant Tube Heater?
Regular maintenance includes checking for gas leaks, ensuring the burner and emitter tubes are clean, and inspecting the reflector for any damage. We recommend having a professional service the heater annually.
What are the installation requirements for Radiant Tube Heaters?
Installation requirements vary based on the type of heater and the specific application. Generally, they need to be suspended from the ceiling, have proper clearance from combustibles, and be vented according to local codes.
