The phrase references compact, often portable, space heaters available for purchase at a large home improvement retailer. These devices serve the purpose of providing localized warmth, especially useful in smaller rooms or targeted areas where centralized heating is insufficient or inefficient.
Such heating solutions offer the advantage of energy savings by heating only the space occupied, reducing overall energy consumption and potentially lowering heating bills. The prevalence of these heaters reflects a consumer need for supplementary or spot heating, particularly during colder months, stemming from desires for increased comfort and cost management.
