Our Verdict
This NewAir heater is built for serious work spaces. It pushes 5600W across 600 sq ft. That covers a full two-car garage with ease.
The thermostat is the standout control feature. It kicks the fan on and off to hold your set temperature. You do not have to babysit the unit.
You need a 240V dedicated circuit to run this heater. Most standard home outlets are 120V. Check your garage wiring before you order.
The specs list tip-over and overheat protection as missing. These are standard on most portable heaters. That gap is worth noting for a unit this powerful.
For garage and workshop heating, this delivers strong performance. The $0.032 price per watt is good value for the power you get. It is not the right fit for bedrooms, offices, or living rooms.
What We Like
- 5600W heats up to 600 sq ft, covering a full two-car garage in one unit.
- Built-in thermostat holds your exact target temperature automatically.
- Powder-coated steel body handles tough garage and workshop environments.
- Integrated cord wrap and carry handle let you reposition it quickly.
- Price per watt is $0.032, well below the $0.06 good-value benchmark.
What Could Be Better
- No tip-over protection, a standard safety feature on most portable heaters.
- Specs do not confirm overheat protection despite manufacturer marketing claims.
- No timer means you cannot schedule heating cycles to start before you arrive.
- No remote control forces you to walk to the unit to change settings.
- 5600W requires a 240V dedicated circuit, ruling out standard 120V home outlets.
