Marley LFK151 High Capacity Wall Heater 1500W 120V

Product Description

The MARLEY LFK151 is a high-capacity electric wall heater rated at 1,500 watts and 120 volts, delivering up to 5,120 BTU/h of supplemental heat. Designed for permanent wall installation, it moves 100 cubic feet per minute (CFM) of conditioned air through the space and draws 12.5 amps at full load. The unit measures 14.625 inches wide, 3.875 inches deep, and 18.25 inches tall, making it well-suited for applications where wall cavity depth is limited. Licensed electricians and HVAC technicians are the typical installers. The heater is intended for residential and light commercial use where a compact, high-output wall-mounted solution is required.

The LFK151 is appropriate for residential rooms, offices, bathrooms, utility spaces, and similar areas that need reliable supplemental or primary electric heat. Its 100 CFM airflow rating supports effective heat distribution in small to medium-sized spaces. The unit mounts directly into the wall cavity and is fed from a dedicated 120-volt branch circuit. Its compact depth of 3.875 inches allows installation in standard stud-bay walls without major modification.
