Lasko 5572 Oscillating Ceramic Tower Heater
Lasko
- ✓29-inch oscillating tower
- ✓1500W ceramic element
- ✓Overheat protection and cool-touch housing
- ✓Adjustable thermostat
- ✓Sturdy tip-resistant base
Pros
- Oscillation covers a workbench and the surrounding floor area without repositioning
- Durable, well-tested design with a large ratings history in garage-style use cases
- Overheat protection is reassuring in a space with sawdust or fuel vapors nearby
- Affordable enough to dedicate permanently to a garage rather than moving it indoors
Cons
- Fan intake can pull in sawdust or dust over time and needs periodic cleaning
- Plastic housing is less rugged than a metal-bodied radiator
- 2 fixed heat settings rather than a precise dial
Best all-around garage heater. Oscillation and overheat protection at a price low enough to leave in the workshop.
De'Longhi Dragon Digital Oil-Filled Radiator TRD40615EBK
De'Longhi
- ✓1500W oil-filled radiator
- ✓No fan, fanless convection heating
- ✓Digital timer and ECO mode
- ✓3 heat settings
- ✓Metal radiator body
Pros

- Metal radiator body holds up better to garage conditions than plastic housings
- Holds heat for a while after shutoff, useful for a garage you check on periodically
- Quiet enough to run while using power tools nearby
Cons
- Slow to warm up, not ideal if you need heat the moment you walk in
- Bulky footprint takes up floor space near a workbench
- Surface gets hot to the touch, needs clearance from stored materials
Best for a woodworking or dusty garage. No fan intake to clog, at the cost of slower warmup.
Dreo Solaris 317 Space Heater
Dreo
- ✓1500W PTC ceramic heating element
- ✓70-degree oscillation
- ✓ETL-certified tip-over and overheat protection
- ✓Digital thermostat with remote
- ✓12-hour timer
Pros
- 70-degree oscillation spreads warmth across a two-bay garage workspace
- ETL-certified safety protections matter around tools and stored materials
- Remote control is convenient when your hands are full of tools
- Faster to reach target temperature than the oil-filled radiator
Cons
- Fan intake needs occasional cleaning in a dusty garage
- Plastic housing is less rugged for rough workshop conditions
- Costs more than the Lasko 5572 for similar oscillating coverage
Best for a garage used as an active workspace where you move between different areas.
Lasko CT16450 Ceramic Space Heater
Lasko
- ✓15.7-inch compact ceramic heater
- ✓1500W element
- ✓Adjustable thermostat
- ✓2 heat settings plus fan-only
- ✓Overheat protection
Pros
- Small footprint fits easily on a workbench or shelf near an outlet
- Affordable enough to keep as a dedicated garage-only unit
- Simple dial controls work fine with gloves on
Cons
- No oscillation, heats only the direction it's pointed
- Lower ratings volume than the Lasko 5572 or Dreo Solaris
- Noticeable low buzzing noise reported by some owners
Best for a small garage corner or workbench where a compact footprint matters more than coverage.
A garage isn't insulated like a bedroom, and most space heaters weren't designed with sawdust and cold concrete floors in mind.
The best space heaters for garages balance real heat output with durability, since a plastic tower heater sitting next to a table saw sees different conditions than one in a living room.
In this category, the Lasko 5572's oscillating tower covered a two-bay workbench area well and held up to repeated garage use without issue.
The De'Longhi Dragon Digital, an oil-filled radiator with no fan, avoided pulling sawdust into an intake, at the cost of a slower warmup than the ceramic models.
For an active workspace where you move between tasks, the Dreo Solaris 317's 70-degree oscillation and ETL-certified safety protections stood out, and the compact Lasko CT16450 works well tucked onto a workbench shelf.
The Best Space Heaters for Garages at a Glance
Best overall: Lasko 5572, oscillating coverage and overheat protection at a price low enough to leave permanently in the garage.
Best for dusty workshops: De'Longhi Dragon Digital, no fan intake to clog with sawdust, holds heat after shutoff.
Best for an active workspace: Dreo Solaris 317, wide oscillation and certified safety protections for a garage you're actively working in.
Best compact pick: Lasko CT16450, a small footprint for a workbench corner.
What Matters Most in a Garage
Dust exposure: fan-driven ceramic heaters (Lasko, Dreo) pull air through an intake that can collect sawdust over time. Oil-filled radiators (De'Longhi) have no fan and hold up better in dusty conditions.
Safety near flammables: keep any heater at least 3 feet from gas cans, solvents, or paper. Tip-over shutoff and overheat protection, present on the Lasko 5572 and Dreo Solaris, matter more in a workshop than a living room.
Warmup speed: ceramic and PTC heaters reach usable temperature in a few minutes, useful if you're only in the garage briefly. Oil-filled radiators take longer but hold heat after you've moved to another task.
Circuit capacity: a garage outlet on an older or shared circuit is more prone to tripping under a 1500W load. Check the breaker rating before running a heater alongside other tools.
