Greenworks G24HG Cordless Heat Gun (Hot Air Gun) with Fast 9-Second Heat-Up

Quick overview

If you’re the sort of DIYer who ends up using a heat gun more often than you planned, the Greenworks G24HG is designed around speed and control. The headline here is fast heat-up in 9 seconds, plus two fan speed settings and an LED light for working where it’s hard to see. It’s a cordless hot air tool, but this particular pack is a “tool-only” version, so you’ll need a compatible Greenworks 24V battery already.

On paper, that makes it a sensible choice for common home-and-garage tasks: lifting/peeling materials, drying timber, or getting paint off surfaces without dragging a lead around. It also comes with three different nozzles, which helps when you want the heat to land in a particular spot rather than spreading everywhere.

Key features worth knowing

The G24HG is built as a practical heat gun for DIY and light workshop jobs, with features that address the everyday annoyances people run into with hot air guns.

First, the heat-up time is the big selling point: reaching working temperature quickly in 9 seconds helps you start the job without standing around waiting. Next, you get two fan speeds, so you can increase airflow for faster heat transfer or dial things back when you want more patience.

Then there are the nozzles. You receive: - A reduction nozzle to concentrate heat towards corners and awkward angles. - A reflector nozzle aimed at bending plastic pipe work. - A flat nozzle for tasks like removing vinyl and stripping paint from doors or metal.

There’s also an LED light intended for darker areas, which is one of those “small” additions that can make a noticeable difference when you’re working in a shed, loft access, or under-cabinet space.

What stands out in use (and what to watch)

In real-world DIY use, the combination of cordless freedom, quick warm-up, and nozzle swapping tends to be where tools like this either shine or disappoint.

The benefit you’ll likely notice day to day is responsiveness. If you’ve ever tried to time your work around a heat gun that takes ages to warm up, the 9-second claim is exactly the sort of thing that can make the tool feel easier to live with.

Worth noting, though: because the pack is described as WITHOUT a 24V battery & charger, it depends pretty heavily on what you already own. If you don’t have a Greenworks 24V system, you may end up spending extra just to get it running. It also means you’ll want to think about battery capacity and whether you’re planning longer sessions.

Also, while two fan speeds and three nozzles give flexibility, it’s still a DIY-focused model rather than something you’d buy if you’re expecting industrial-level continuous use without downtime.

Where it makes sense to buy

This tool fits best if you: - Already have Greenworks 24V batteries and want a cordless hot air gun without duplicating battery gear. - Do DIY projects like removing vinyl, stripping paint, or lifting films where a nozzle-led approach is useful. - Want a heat gun that warms up quickly so you’re not waiting around before you can start. - Need some working light for tight or dim areas.

A simple example: say you’re working on a door where old paint needs removing. With the flat nozzle fitted, the idea is to direct the heat along the surface area rather than blasting heat into thin spots. For corners or edges, you’d switch to the reduction nozzle to focus heat more precisely.

If you’re currently using a basic, lower-end heat gun or relying on a wired model for occasional jobs, the cordless nature and quick warm-up are the kind of upgrades that can feel genuinely convenient.

Buying verdict

It’s a good fit if you already sit inside the Greenworks 24V ecosystem and you want a cordless heat gun that starts quickly and lets you tackle a range of DIY tasks using different nozzles. The 9-second heat-up, two airflow settings, and LED light are all practical features that match what you’ll actually notice while working.

It might not be a great match if you don’t already own a compatible Greenworks 24V battery, because the pack is specifically tool-only. In that case, your total cost and “time to first use” will depend on picking up the missing battery and charger.

If you’re aiming for something very basic and don’t need nozzle versatility, you may find simpler heat guns meet the minimum. But if your projects involve corners, plastic pipe work, vinyl removal, or paint stripping, the nozzle set and airflow control give this model a clearer job-focused edge.
