Garage heaters have caught up with indoor heaters this year. The 2026 crop of 240V units adds ECO modes, timers, remotes and even app control, while a new infrared tripod heater gives 120V garages something better than a small ceramic box. A garage is a different job from a bedroom: it is poorly insulated, the door leaks air and concrete soaks up heat, so raw output and the right fuel or circuit matter.
For this 2026 guide we focused on models released or upgraded for the 2025–2026 season and compared heat output for the space, power or fuel requirements, controls, safety and installation. We used manufacturer specifications, independent tests and owner feedback. For scored tests of popular garage heaters, see our space heater for garage reviews; for long-term favorites, our best rated space heater for garage guide. Our Editorial Policy explains how we choose products.
