Installation is straightforward, as the unit can be recessed or surface-mounted, making it versatile for different setups. However, the heater may still feel a bit bulky at 22 pounds and could require some effort for wall-mounting. Additionally, while the unit is efficient, the built-in thermostat may not be precise enough for users seeking highly accurate temperature control.
