  • Product Overview

    Anyone who has ever worked in an office setting knows that one central thermostat setting is not going to please everybody. Inevitably, someone is too hot; another is too cold – and the cycle drags on. Now, you can end the fight over choosing the perfect thermostat setting by using the Qmark 202SLB Radiant Under Desk Heater to stay comfortable in your immediate surroundings. Manufactured by Marley Engineered Products, the Qmark 202SLB Heater – alternatively named the Work Warmer – is a slim and lightweight personal space heater that is designed to give you personalized warmth while you work.

    The 8-pound Work Warmer desk heater mounts easily to the inside of your desk well with the included Velcro tape or uses stabilizing feet to stand up underneath a desk, counter, hobby table, or sewing table. With a unique crystalline surface, the panel heater emits gentle radiant heat to warm your work area to a comfortable temperature. This not only keeps your surroundings bearable, it also helps your productivity. This Qmark heater is designed with administrative assistants, bank tellers, receptionists, cashiers, teachers, architects, accountants – and anyone else who works at a desk, counter, or hobby table – in mind.

    Economical Heat

    Using this under desk heater for warmth in your workspace costs just one or two pennies per hour, based on your local electricity rate. Ultimately, this can help you save money on your energy bill by allowing you to limit the temperature setting on your central thermostat. You can then use the 202SLB unit to heat only the space you occupy. This is a great benefit for offices and other settings where multiple people work together in one space. Workers have more individual control over their comfort, which in turn, increases productivity and conserves energy.

    Safety Features

    The Qmark WorkWarmer Radiant Heating Panel also provides safe, worry-free operation. With a surface temperature measuring below 200 degrees Fahrenheit and no exposed heating elements, the under desk heater is cool to the touch and carries little risk of burns. For additional safety, the unit features an automatic tip-over safety switch that shuts off the heater in the event that it tips over. It is also equipped with a 120-volt-rated polarized plug for electrical shock protection.

      Comments about QMark Radiant Under Desk Heater:

      These heaters are very efficient, and are slowly replacing all of the 1500 watt space heaters in our building. Sylvane offered the best price as well.

        Doesn't Trip Breakers

        By Mike Ling

        from USA

        Comments about QMark Radiant Under Desk Heater:

        I have a few of my employees use this heater. It is quiet and warm and uses only about 20% the power. I had problems before with some 1500 watt under desk heaters that would trip the breaker every once in a while when they would come on all at the same time. The only drawback is that sometimes they leave them on overnight (including me). The energy savings makes up for the higher price, I think. I've used it for 6 seasons and still working.

        So much better than a fan heater

        By Patty

        from USA

        Verified Buyer

        Comments about QMark Radiant Under Desk Heater:

        This heater was the answer to all my problems! I've tried many different under-desk heaters and this is the best. It gives off gentle, even heat. Its color and slim profile make it look innocuous. And best of all, it's absolutely silent. Fan heaters dry out my skin and the on-and-off cycling make my legs feel alternately hot and cold. The steady heat from this radiant heater is so much better. Plus, it uses much less power.
