Unit Heater · 12.5 kW 240/208V 1-Phase · Built-In Thermostat and Mounting Bracket · King Electric KB2412-1-T-B2
What this product is for
The King Electric KB2412-1-T-B2 is a suspended fan-forced unit heater for electric space heating in garages, workshops, warehouses, mechanical rooms, and similar commercial or industrial spaces. It is a 12.5 kW, 240/208V, 1-phase heater with built-in thermostat control and a universal mounting bracket.
Use for
Use for primary or supplemental heat in open areas where wall or ceiling mounting is preferred and directional airflow is needed. Adjustable louvers help aim heat into work areas, vehicle bays, storage zones, or service counters.
Avoid for
Avoid for hazardous locations, washdown areas, or corrosive environments unless the installation conditions specifically match the heater listing and enclosure requirements. It is also not the right choice where lower-voltage branch circuits or quiet radiant heat are required.
Best for
Best for electricians and contractors specifying electric unit heat in garages, warehouses, fire pump or service rooms, and utility spaces where 240V 1-phase power is available. Typical guidance for electric heat is about 10 W per sq ft in reasonably insulated spaces, so 12.5 kW is commonly considered for roughly 1,250 sq ft (about 116 m²), but actual performance depends on installation conditions, insulation, layout, ceiling height, infiltration, and local electrical code.
Installed in
Commonly installed on walls or ceilings using the included bracket in garages, workshops, warehouses, water treatment rooms, and similar service areas. Manufacturer air throw is approximately 28 ft (8.5 m) with a maximum mounting height of 11 ft (3.4 m).
Why this product exists
This heater is designed to deliver concentrated electric heat with forced air circulation where baseboard or wall heaters are not practical. The built-in thermostat simplifies control, and the bracket supports suspended installation in spaces where floor and wall area need to stay clear.
Compared with similar products
Compared with smaller unit heaters, this 12.5 kW model provides higher heat output and longer air throw for larger spaces. Compared with more advanced KB variants, this standard KB configuration focuses on core unit-heater performance with built-in thermostat control and bracket mounting rather than upgraded electronic staging or specialty controls.
