While the heater delivers strong heat output, it may generate some noise due to its fan-forced design, which is typical for this type of unit. Operating at 10,000 watts means it can impact your electricity bill, so using the timer and thermostat wisely is important for energy efficiency. This heater is ideal if you want a robust, reliable ceiling-mounted solution with good heat coverage and convenient controls for a garage or workshop. If you prefer something quieter or easier to install, you might consider other types, but within its category, the CZ260ER offers solid performance and safety features suited for hardworking spaces.
