The heater is able to heat up any residential or industrial plant area up to 600 sq ft. Additionally, you needn’t hang it; you can place it on the floor (preferably on a concrete one).

Its lightweight and compact size can be moved around easily and stored in the summer without taking much space.

It comfortably heats rooms with temperatures ranging from 45 to 95 degrees providing a warm and comfortably working space. Moreover, this heater comes with a thermostat control that lets you conveniently control the temperatures to your liking. It is UL and C-UL certified.
This device is also very quiet when operating as Mr. Infrared Heater designed the single fan to move air from the heating system without an overabundance of noisy moving parts. As a result of this quiet design, this unit’s maximum sound generation only reaches a very quiet 45 decibels.
It is not only good for a medium sized garage it can also be very useful in the basement, workshop or any other place where heater might be necessary. It has a thermostat, which can be adjusted to high or low. It is also strong and long lasting with its the built style. Since it is portable it can be moved from place to place according to the need. This is a heater which is very well constructed and made for easy use.
Built-in thermostat allows for effective temperature control. Quiet and no noise pollution.
Among others, one of the best things about this product is its built-in thermostat, which will make it easy for you to adjust the temperature from low to high. This also means that you will have complete control in choosing the heat output of the product. Another feature that is worth noting is the built-in storage for the cord. When it is stored, you can keep it neat. This will also prevent the cord from ending up being tangled.
This is excellent for 1 and 2 car garages.
With its steel casing, it’s also exceptionally safe. One other thing you might notice with DR-988 is the fan. The combination of electricity and fanning gives this heater the ability to cover 600 sq. ft. of space, more than enough for a medium-sized garage. So, to sum up – bright-red, electric, portable, fan-driven, small, lightweight, and durable.
This is not a necessity for a good workshop heater, but it’s definitely a big plus. This heater is able to distribute the warm air over a large surface. The big fan pushes the hot air further into a room than other space heaters.

What reviewers didn't like

It is not designed for standard residential use and requires a 220V plugin which is rare in many circumstances.
However, it is not suitable for general residential or household use and cannot be mounted on ceilings.
This heater is a little loud
On the downside, the warranty is only 100 days. The thermostat is also interchangeable. Don’t expect any rattles from the fan – it will be pretty quiet. There’s also overheat protection but no remote control.
Some users have reported only a minimal temperature difference of less than 1 degree in their garage space when using this heater.
It’s bright red and sticks out like a sore AC thumb.
- Cozzy
This doesnt employ a mounting bracket.
This one is an infrared heater which is slow in heating.
It is a bit expensive.
Motor can produce a loud noise and can be a potential fire hazard.
This may need re-wiring depending on your electrical setup and strong fan creates moderate noise.
No remote control and has only single-direction blowing of heat.
This unit’s red color is very noticeable. Everybody’s eyes will be attracted to it. This might not be the best feature if you’re looking for a good shop heater. Some people complain that this model makes rattling sounds when it works. The fan operates silently, but the whole unit might shake and make those sounds. If this is the case, place the unit on an even surface.
