The Convectair FLB+ is designed to heat small to medium-sized rooms up to 250 square feet. It operates at 2000 watts, providing efficient and consistent heating.

Some models of the FLB+ come with a built-in thermostat, but it might be positioned low on the unit, making adjustments slightly inconvenient. For more precise control, it can be paired with an external wall thermostat.

While generally quiet, some users have reported that the heater can produce creaks and other noises during operation, particularly as it heats up and cools down.

The heater is wall-mounted and can be installed relatively easily, but it does require some wiring work. Professional installation is recommended to ensure safety and proper function, especially for those unfamiliar with electrical work.

The heater is around 32.5 inches wide and can protrude more than expected, particularly when including the mounting bracket. This may be a consideration if space is a concern.

The Convectair FLB+ requires minimal maintenance, mainly regular cleaning of the inlet grid to ensure optimal performance. It’s important to avoid using abrasive cleaners on the unit's surface.
