What I Looked for Before Buying
Before I decided on this heater, I focused on a few important things. I wanted to know how much space it could heat, how easy it was to install, and whether it would be safe to run for extended periods. I also checked if it came with the necessary parts for setup, since I did not want to buy extra accessories right away. For me, ease of use mattered just as much as heating power.
