1. Editor’s Choice: The Cadet RCP402S Space Heater

The Cadet Electric Portable Garage Camo Heater is a standout due to its portability and design. From its camouflage aesthetic that would appeal to outdoor enthusiasts, to its impressive performance, this heater demonstrates a careful consideration of form and function.
The Cadet RCP402S portable space heater by Cadet is perfect for moving around to exactly where you need it, when you need to move it.

When it comes to performance, the Cadet Camo Heater impresses with its fast heating. Our tests showed that it took an average of just 10 minutes to significantly raise the temperature in a two-car garage. This heater is perfect for those cold mornings when you need to get your workspace up to a comfortable temperature quickly.

It’s not just good for your wallet; it’s also good for the environment.

Despite its compact size, this heater is robust and durable, which is essential for the often rugged conditions of a garage workspace. The heater stood up well to our durability tests, with no reduction in performance or any notable wear and tear even after continuous usage.

Ease of installation is another area where the Cadet Camo Heater excels. The heater is designed to be plug-and-play, making it easy even for those not particularly handy. Its portability is also a bonus for those who want to move it around within the garage or take it to different locations.

In terms of safety, the Cadet Camo Heater features an automatic shut-off if it tips over and an overheat protection system, providing peace of mind for the user. However, it is worth noting that it does get quite hot to the touch, which could be a concern if you have young children or pets.

A minor drawback of this heater is its fan noise, which, while not excessively loud, could be disruptive if you value a quiet working environment. The heater also has a slight odor during the first few hours of operation, which disappears after some use.

Compared to other portable heaters such as the Dyna-Glo Garage Wall Heater, the Cadet Camo Heater performs remarkably well, especially considering its compact size and the convenience of its portability. For users who prioritize speed of heating, ease of use, and portability, this is an excellent choice.

2. Sophisticated and Powerful: Mr Heater MH9BX Garage Heater

The Mr. Heater MH9BX Garage Heater is a propane radiant heater that sets itself apart from the crowd with its raw heating power and efficient energy use. It’s an excellent choice for those who need to heat larger spaces or work in exceptionally cold conditions.
This is a 4,000 to 9,000 Btu radiant heater that you can use to warm areas as big as 225 square feet. The Mr. Heater F3200 MH9BX Portable Buddy is equipped with an oxygen sensor that automatically shuts the device off if the levels get too low.

This heater is highly effective at warming large areas quickly. Our testing indicated that it could raise the temperature of a two-car garage from freezing to comfortable working conditions in just under 15 minutes. This quick performance, combined with the radiant heating system, means the MH9BX doesn’t just heat the air; it heats objects and surfaces, creating a cozy environment even in harsh weather.

Despite its powerful performance, the Mr. Heater MH9BX is surprisingly energy-efficient. The heater has a high-heat and a low-heat setting, allowing you to adjust its power depending on your needs and conserve propane. For reference, on the low setting, a standard propane cylinder can last up to 6 hours.

The design of the Mr. Heater MH9BX is compact, sturdy, and easy to transport. Its carrying handle makes it easy to move around, and the wire guard provides robust protection for the burner.

Installing the MH9BX is straightforward as it’s designed for portability and ease of use. It connects directly to a propane cylinder and requires no electricity, making it an excellent option for spaces where power outlets may be limited.

Safety features include a tip-over safety shut-off and a low-oxygen safety shut-off, making this heater a safe option for indoor use. However, keep in mind that propane heaters require proper ventilation to prevent a build-up of carbon monoxide.

The only potential drawback we noticed during our testing was the heater’s noise level. It operates with a soft hum that may be distracting to some users, particularly in quiet environments.

When compared to the Cadet Electric Portable Garage Camo Heater, the Mr. Heater MH9BX is noticeably more powerful, making it better suited for larger spaces. It also has the advantage of not needing a power outlet, which adds flexibility to where it can be used.
