A specific type of portable heating appliance, often sought after at a major home improvement retailer, utilizes electricity to generate warmth and propel it forward. These devices are characterized by a cylindrical shape reminiscent of a certain underwater projectile, hence the descriptive name. They are primarily intended for use in well-ventilated spaces such as garages, workshops, and construction sites.
Such heating solutions offer a convenient and relatively inexpensive way to provide temporary or localized heat. Their availability at a readily accessible retail outlet enhances their appeal for consumers seeking immediate solutions for cold environments. Historically, these units have provided a more accessible alternative to central heating systems in areas where such infrastructure is either absent or impractical.
