Heat Guns
A heat gun is the fix when you need controlled heat on site, without burning or bodging it with a flame.
From heat shrink on cable joints to stripping paint and freeing stuck fixings, a decent hot air gun gives you clean, targeted heat. Choose 110V for site power, or a cordless heat gun when you're up ladders or working punch-list jobs.
What Are Heat Guns Used For?
- Heat Shrink and Cable Work Shrinking sleeving, boots, and labels evenly without scorching, especially when you need a proper finish on first fix and snagging.
- Paint and Adhesive Removal Softening old paint, vinyl, mastic, and stubborn stickers so you can scrape cleanly without chewing up timber or plaster.
- Freeing Stuck Fixings Warming seized bolts, threaded rod, and old pipe fittings to break the bond, so you are not rounding heads or snapping hardware.
- Forming and Bending Plastics Gently heating PVC, acrylic, and trims to shape and fit, handy for second fix, shopfitting, and tidy finishing details.
- Controlled Drying Drying damp patches, filler, or small paint repairs when you need to move the job on, without blasting dust everywhere like a fan heater.
Choosing the Right Heat Gun
Match the heat gun to the job and the access, because the wrong one either cooks the surface or takes all day to get warm.
1. Corded vs Cordless
If you are stripping paint for hours or working in one spot, an electric heat gun makes sense for constant run time. If you are on ladders, in lofts, or bouncing between small fixes, a cordless heat gun is the one you will actually grab because there is no lead to drag or melt.
2. 110V Heat Gun vs 230V
If you are on a commercial site, a 110v heat gun is usually the safe, standard choice with site power. If you are in a workshop or domestic setting with normal mains, 230V is fine, but do not turn up to site assuming you will have it.
3. Temperature Control and Airflow
For heat shrink and delicate trims, go for proper variable temperature and airflow so you can warm evenly without blistering. For heavy stripping, higher heat and strong airflow shifts material faster, but you still want control so you are not charring frames and skirtings.
4. Size and Nozzles
If you are working in tight panels or around finished work, a mini heat gun or a slimmer front end is easier to aim without cooking everything nearby. Make sure the range has reducer and reflector nozzles available, because that is what turns a hot air gun into a proper heat shrink gun.
Who Uses Heat Guns on Site?
- Sparkies and comms engineers for heat shrink gun work on terminations, labels, and sleeving where a lighter is a straight no.
- Decorators and maintenance teams for stripping paint and lifting old adhesive during refurbs and patch repairs.
- Plumbers and heating engineers for warming seized fittings and easing off old sealants without risking open flame near finished surfaces.
- Joiners, kitchen fitters, and shopfitters for forming trims and making neat adjustments when parts need persuading into place.
The Basics: Understanding Heat Guns
A heatgun is basically controlled hot air you can aim. The difference between a tidy finish and a melted mess is temperature, airflow, and the right nozzle.
1. Heat and Airflow Work Together
Higher airflow moves heat across a wider area for stripping and drying, while lower airflow gives you control for heat shrink and plastics where you need even heat without blowing material about.
2. Nozzles Make It Job-Specific
A reducer nozzle concentrates heat for small targets like terminals and sleeving, and a reflector nozzle wraps heat around pipe or cable so you are not chasing it round with the gun.
3. Cordless Heat Guns Trade Run Time for Access
A battery heat gun is all about getting the job done where a lead is a pain, but expect shorter bursts of use, so keep a spare battery if you are doing repeated heat shrink gun work all day.
Heat Gun Accessories That Make the Job Cleaner
The right nozzle and a couple of basics stop you overheating the work and redoing it.
1. Reducer Nozzle
This focuses the airflow so you can shrink sleeving and heat shrink tubing neatly without warming the whole panel, which is exactly what you want from a heat shrink gun set-up.
2. Reflector Nozzle
A reflector nozzle wraps heat around pipe and cable, saving you from constantly rotating the work and ending up with one side cooked and the other side still loose.
3. Scraper Set
If you are using an electric heat gun for stripping, a proper scraper set makes the difference between lifting paint cleanly and gouging timber because you are levering too hard.

Heat Gun FAQs
What is a heat gun used for?
On site it is mainly for heat shrink, stripping paint and adhesive, warming seized fixings, and forming plastics and trims. A heat gun gives you controlled, targeted heat without an open flame, so it is safer around finished surfaces and tight areas.
Does a hair dryer work as a heat gun?
Not really for trade jobs. A hair dryer does not get hot enough or focused enough for proper heat shrink gun work, paint stripping, or freeing fixings, and you end up wasting time and overheating the dryer instead of the material.
What is a cheap alternative to a heat gun?
If you only need gentle warming, a hair dryer can do small, non-critical jobs, and for some shrink work a lighter can work in a pinch, but it is messy and easy to scorch. For anything you want to look tidy and repeatable, a basic electric heat gun is the cheapest option that actually does the job properly.
Can I use a heat gun to dry paint?
Yes, for small areas and touch-ups, but you need to keep the gun moving and use a lower setting so you do not blister the surface or skin the top while the underneath stays soft. It is a time-saver for snagging, not a replacement for proper cure time on full walls.
Is a cordless heat gun worth it, or will it just chew batteries?
It is worth it when access is the problem, like ladders, lofts, and quick call-outs, because you are not trailing a lead through finished areas. They do use battery fast on high heat, so treat it like a burst-use tool and keep a spare battery if you are doing repeated heat shrink gun jobs.
Do I need a 110V heat gun on site?
If you are on most commercial sites, yes, because 110V is the standard for powered tools. If you are working domestic or in a workshop, 230V is fine, and if you are moving room to room a battery hot air gun can be the simplest option.
