Intro
Around the house, in the workshop, and out in the garden, there are countless tasks that need controlled, focused heat to get the job done right. Stripping old layers of paint from a window frame, softening adhesive to remove a stubborn sticker or vinyl flooring, thawing a frozen outdoor pipe in winter, or shrinking heat-shrink tubing around electrical connections — all of these jobs are made far easier with a hot air gun. Unlike a basic hair dryer, a proper hot air gun reaches temperatures of 300 °C to 500 °C or more, delivering the intense, directed heat needed to soften, melt, or dry materials quickly. They are a staple tool for DIY renovators, electricians, automotive hobbyists, and anyone who works with plastics, adhesives, or coatings. A good hot air gun gives you control over the temperature so you do not scorch what you are working on, and it should be light enough to hold comfortably for the duration of the task. From lighting a barbecue without chemical starters to bending PVC conduit into shape, a versatile hot air gun earns its place in the toolbox surprisingly fast.
Generalities
When choosing a hot air gun, the most important specification is the temperature range and how it is controlled. Basic models offer one or two fixed temperature settings — typically around 300 °C and 500 °C — which cover the majority of common household and workshop tasks. More advanced models feature a rotary dial or digital display for stepless temperature adjustment, giving you finer control for sensitive materials. Wattage, usually between 1200 and 2000 W, determines how quickly the tool reaches its operating temperature and how well it maintains heat under continuous use. Weight and balance matter more than you might think — stripping paint from a door frame means holding the tool at various angles for extended periods, and a well-balanced gun weighing under 800 grams will feel noticeably less tiring than a heavier, nose-heavy alternative. Steinel is a German brand with decades of experience in hot air technology, known for producing reliable tools that find their way into both professional workshops and home DIY kits.
In this review we take a close look at the Steinel HM 1620 S — a 1600 W hot air gun with two temperature levels at 300 °C and 500 °C. We examine its power output, build quality, ergonomics, safety features, and the range of tasks it can handle. We also discuss its strengths and limitations honestly, so you can decide whether it is the right hot air gun for your needs.
Description
The Steinel HM 1620 S is a mains-powered hot air gun rated at 1600 W, running on a 240 V AC household supply. It offers two fixed temperature settings: 300 °C for gentler tasks like drying paint, softening adhesives, and shrinking tubing, and 500 °C for heavier-duty work such as stripping old paint, welding plastics, and thawing frozen metal pipes. The tool reaches operating temperature quickly thanks to the 1600 W heating element, and the airflow is strong enough to distribute heat evenly across the work surface. The body is made from high-temperature-resistant plastic and weighs approximately 670 to 720 grams depending on the source — light enough to hold comfortably for extended periods. The product dimensions are 25.2 × 8.6 × 20 cm, making it compact enough to store in a standard toolbox drawer.
Steinel has paid particular attention to the balance and handling of the HM 1620 S. The centre of gravity is positioned close to the grip, so the tool does not feel nose-heavy when you are working at different angles. This matters a lot in practice — when you are stripping paint from a vertical door frame or holding the gun above your head to soften ceiling adhesive, a well-balanced tool reduces wrist strain noticeably. The charcoal-coloured plastic housing stays cool to the touch on the grip area, and the integrated thermal safety cut-out automatically shuts the tool down if it overheats, protecting both the tool and the user. The two-position switch on the handle lets you toggle between off, 300 °C, and 500 °C with a simple thumb movement — no dials to fiddle with, no digital displays to read.
In everyday use, the HM 1620 S proves itself to be a capable and straightforward tool. The two temperature settings cover the vast majority of typical hot air gun tasks, and switching between them is instant. At the 300 °C setting, the gentle heat is ideal for drying fresh paint between coats, softening self-adhesive vinyl tiles for removal, or shrinking heat-shrink tubing onto electrical connections without scorching the insulation. Switch to 500 °C and the tool tackles tougher jobs — baked-on paint peels away from timber under a paint scraper, frozen padlocks thaw in seconds, and rigid PVC conduit softens enough to bend around corners. The tool includes a basic nozzle as standard, and while it does not come with a full accessory kit, Steinel's range of compatible nozzles (sold separately) covers everything from wide-slot spreader nozzles to reflector nozzles for soldering and welding.
The HM 1620 S ships as a standalone unit with the thermal stripping nozzle included — described by Steinel as the HM 1620 E thermal stripper configuration. The power cord is of generous length, giving you reasonable mobility around the work area without needing an extension lead for most indoor tasks. The tool's simple control scheme means there is practically no learning curve: plug it in, select your temperature, and wait a few seconds for the element to heat up. The plastic housing is durable enough for regular workshop and home use, though it is not designed to withstand being dropped from height onto concrete. One thoughtful inclusion is the thermal safety cut-out — if the tool is accidentally left running face-down on a surface, it will shut off before causing damage, which is reassuring for anyone who has ever worried about walking away from a hot tool.
Dimensionally, the Steinel HM 1620 S measures 25.2 cm long, 8.6 cm wide, and 20 cm tall — a compact footprint that stores easily. At roughly 670 to 720 grams it is among the lighter hot air guns in its power class, and the balanced design means you can work for longer without your forearm burning out. It is rated 4.3 out of 5 stars based on 11 customer reviews on Amazon France, and holds a bestseller rank of #178 in the Hot Air Guns category. Priced at approximately €42, it represents excellent value from a respected German brand known for hot air technology. The voltage rating of 240 V makes it suitable for use across European mains supplies. While Steinel does not publish spare part availability information, the brand's reputation for durability suggests this tool should deliver years of reliable service with reasonable care.
Pros and cons

Cons
- Only two fixed temperature settings with no stepless adjustment — if you need precise temperature control for sensitive materials like certain plastics or low-temperature adhesives, a variable-temperature model would offer more flexibility.
- Limited accessory set included out of the box — you get the basic nozzle only, so specialist tasks like soldering, welding, or wide-area paint stripping will require purchasing additional Steinel-compatible nozzles separately.
- Plastic housing, while lightweight and cool-running, is less impact-resistant than metal-bodied alternatives — a drop from height onto a hard floor could crack the casing, so handle with reasonable care.
- Only 11 customer reviews on Amazon France at the time of writing, which is a relatively small sample size for judging long-term reliability — early adopters should keep this in mind.
- No spare parts availability information provided by the manufacturer, meaning that if a component fails outside the warranty period, repair options may be limited or uneconomical.
Use cases
The Steinel HM 1620 S is ideal for DIY renovators, hobbyists, and occasional professional users who need a reliable, lightweight hot air gun for paint stripping, adhesive removal, heat-shrinking, thawing, and plastic forming — all at a competitive price from a trusted German brand.
Paint Stripping and Surface Renovation
Removing old, flaking paint from window frames, door frames, skirting boards, and furniture is the classic hot air gun task. The HM 1620 S on its 500 °C setting softens multiple layers of paint quickly, letting you scrape them away cleanly without the mess and fumes of chemical strippers. The balanced weight distribution means you can work along an entire door frame without your wrist cramping up.
Adhesive, Sticker, and Vinyl Flooring Removal
Peeling off stubborn stickers, removing self-adhesive vinyl floor tiles, or softening the glue holding down old carpet underlay all become straightforward with directed heat. The 300 °C setting provides enough warmth to soften adhesives without burning the backing material, making removal cleaner and faster than scraping cold. The compact body lets you get the nozzle close to the work surface even in corners.
Heat-Shrink Tubing and Electrical Insulation
For anyone working with automotive wiring, home electrical projects, or electronics repairs, heat-shrink tubing is essential for insulating and protecting connections. The 300 °C setting delivers consistent, even heat that shrinks tubing uniformly without scorching the insulation or melting nearby wires. The lightweight body makes it easy to position the nozzle precisely around delicate wiring harnesses.
Thawing Frozen Pipes, Padlocks, and Vehicle Components
In cold weather, outdoor pipes, gate padlocks, and car door seals can freeze solid, leaving you stuck. The 500 °C setting of the HM 1620 S delivers enough heat to thaw frozen metal fittings and ice-blocked pipes in minutes. The long power cord gives you reach to outdoor taps and gates without needing an extension lead, and the thermal cut-out provides peace of mind when working near potentially flammable surroundings.
Plastic Forming, Welding, and Creative DIY Projects
Bending PVC conduit for electrical installations, shaping acrylic sheets for custom projects, or welding cracked plastic components back together all require controlled heat. The 500 °C setting of the HM 1620 S brings rigid plastics to a workable temperature quickly, while the ergonomic grip lets you hold the gun steady during precise forming work. For hobbyists making costume armour, model terrain, or custom enclosures, this tool opens up possibilities that a basic heat source simply cannot provide.
