If you are looking for a heater with a beautiful Northern white louvered cover and a three piece construction that makes for easy installation look no further than the Q-Mark LFK404 Electric Wall Heater. The rugged stamped steel front cover provides a down-flow air pattern and is finished in Navajo white. There is a hole plug that is there to prevent tampering with the installation. Uniform heat and long service life is provided by the steel finned metal sheath electric heating elements with low sheath temperature.

The Q-Mark LFK404 Electric Wall Heater is a high capacity, heavy-duty fan-forced wall heater. It can be used almost anywhere in residential, commercial or industrial areas and perform well in motels, entryways, playrooms, basements, workshops, garages, stores and other large areas.

A two pole thermostat is included with the LFK404 electric wall heater so that you are able to turn the heater all the way off. There is also a built-in thermal cut out that disconnects power in event of overheating due to accidental blockage and a fan delay switch that energizes the fan only after the elements are heated to prevent unheated air from being discharged. The fan motor is also only de-energized after the residual heat has dissipated when the heat is shut off. The fan motor is permanently lubricated and totally enclosed to ensure long life, low maintenance and gently distribute warmth throughout room area.

The heater was easy to install I already had an existing 240 outlet so cutting the hole was the biggest job, the auto thermostat is nice which allows me to leave the shop without concern, thanks also for your quick delivery.

The product was exceptionally priced and the delivery was timely. The units were installed in exit stairways replacing undersized heaters and should work nicely this winter.

Needed more heating power over a 110V wall heater in a large bathroom. The Q-Mark LFK404 220V unit blew me away. Even at half power the room is nice and warm in less than 3 minutes.
