What is the Best Workshop Heater

Contents Index:

As colder months settle in, every dedicated DIY enthusiast, mechanic, woodworker, or craftsman knows one thing: staying productive in a chilly workshop can be a challenge. The solution? Investing in a reliable, efficient, and cost-effective workshop heater. Today, we’ll discuss what makes the best workshop heater, explore the different types available, and share scenarios where they truly shine. If you’re searching for high-quality options, check out the workshop heaters at Edison’s, where UNIMAC heaters are trusted by pros and hobbyists alike.


When you spend long hours working in a garage, workshop, or any unheated space, a consistent heat source is essential for comfort, productivity, and safety. Not only does a warm environment help you stay comfortable, but it also protects your tools and materials from the adverse effects of cold and humidity. Whether it’s woodworking, car repair, or crafting, warmth can make all the difference in getting the job done efficiently.

Selecting the best workshop heater depends on various factors like workshop size, insulation, power source, and safety. Here’s a breakdown to help you decide:

  • Space Size: Small workshops may only need a compact electric heater, while larger garages and warehouses could benefit from powerful diesel or propane heaters.
  • Insulation: Poorly insulated spaces might need more powerful heating options, as a lot of heat will escape without proper insulation.
  • Ventilation Needs: If you’re considering fuel-based heaters, ensure adequate ventilation to prevent carbon monoxide buildup.
  • Power Source: Some heaters require a standard electrical outlet, while others operate on gas or diesel. Pick the heater that suits your power availability and workshop setup.

  1. Electric Fan Heaters
  2. Infrared Heaters
  3. Propane Heaters
  4. Diesel Heaters

Each of these options brings unique advantages depending on your needs. Let’s explore how they work, why they’re beneficial, and the specific workshop situations where they excel.


Electric fan heaters are popular for small to medium-sized workshops. They work by drawing air over an electrically heated element and then circulating the warm air around the room.

Benefits:

  • Instant Heat: Fan heaters are great for quickly warming up spaces and are perfect if you don’t want to wait.
  • Portable: Lightweight and compact, they’re easy to move around, making them ideal for small spaces.
  • Clean Energy: No need for fuel or ventilation, making it a safe choice for indoor use.

Where They Shine: If you’re working in a smaller, closed-off space like a garden shed, art studio, or hobby room, an electric fan heater offers quick and reliable warmth. It’s also great for weekend warriors who need warmth only occasionally, as you can plug it in, warm up, and get to work without hassle.


Infrared heaters provide a unique benefit – they don’t heat the air, they heat objects and people directly. This makes them incredibly efficient for targeted warmth without wasting energy heating an entire space.

Benefits:

  • Energy Efficient: Uses less electricity since it doesn’t attempt to warm up all the surrounding air.
  • Targeted Heating: Perfect if you’re working in one area of a larger space.
  • Silent Operation: With no fans or moving parts, infrared heaters run quietly, ideal for peaceful work environments.

Where They Shine: Infrared heaters are perfect for large workshops or garages where heating every corner isn’t necessary. For instance, if you’re working at a bench or stationed at a single workstation, an infrared heater can keep you warm without running up your energy bill. Great for woodworking shops or garages where only a specific zone requires heating.


Propane heaters are known for their high heating capacity, making them suitable for large, uninsulated, and well-ventilated spaces. These heaters use propane gas, so they’re powerful and heat up quickly.

Benefits:

  • Powerful Heat Output: These heaters can warm up larger spaces efficiently.
  • Cost-effective: Propane can be cheaper than electricity in some areas, making it a cost-efficient choice.
  • Portability: Many models are designed to be compact and portable, allowing you to move them around with ease.

Where They Shine: Propane heaters are great for open workshops or garages with good ventilation. For instance, if you’re working in a warehouse, garage, or any setting with open doors or windows, a propane heater provides ample heat without worry. Many construction sites or auto garages choose propane heaters for their blend of power and portability.


Diesel heaters provide an industrial-level heating solution and are designed for heavy-duty applications. These heaters offer robust power and are built to handle long hours of operation, making them ideal for larger, colder workshops or outdoor areas.

Benefits:

  • High Heating Capacity: Diesel heaters are often the most powerful option, designed to keep large, cold spaces warm.
  • Long-lasting Fuel: Diesel fuel provides steady, reliable heat over long periods, ideal for extended work hours.
  • Durability: Built tough, these heaters are often used in demanding industrial settings.

Where They Shine: Diesel heaters are perfect for large, poorly insulated workshops, warehouses, and other industrial workspaces. These heaters can run for extended periods, making them a solid choice for serious DIY projects or professional settings where warmth is essential to productivity.


With powerful heaters come safety responsibilities. Here are some tips to keep in mind:

  1. Keep Heaters Away from Flammable Materials: Ensure there’s no risk of ignition near the heater.
  2. Ventilation is Key for Fuel-based Heaters: Always maintain good airflow for propane or diesel heaters to avoid carbon monoxide buildup.
  3. Use Stable Surfaces: Set up the heater on a flat, stable surface to prevent accidental tipping.
  4. Never Leave Heaters Unattended: It’s best to turn off heaters if you’re stepping out for an extended period.

Ultimately, the best workshop heater for you depends on your workspace’s size, insulation, and power source. Whether you need a compact electric fan heater for a cozy garage or a robust diesel heater for a large, drafty warehouse, there’s an ideal option out there to keep you comfortable and productive.
