|---|---|---|

| Heating performance | 6.5750/1,500 W with thermostat; owners report the thermostat is inconsistent. | 6.51,500 W with thermostat; heat doesn't scale with the 68-inch width. |
| Installation & fit | 6.5Existing firebox only; no hardwire option; check the height variant. | 8.5Fits 2x6 studs or mounts on the surface; the 67 lb weight needs a solid wall. |
| Controls & features | 7.0Remote, thermostat, flame-only mode and crackle sound. | 7.5Thermostat, timer, sleep mode and touch panel; no smart control. |
| Reliability & build quality | 6.0Owners report some heater failures; warranty is unpublished. | 6.0Series reports of a finicky remote, grinding noise and units damaged on arrival. |
