Wall heaters are heating units installed into or directly attached to a wall. They are most commonly found inside studio or bachelor apartments and compact offices. They are suitable for small spaces because they provide adequate heating while conserving floor space. Coming into use more than 60 years ago, are they still viable today? This two-part article discusses why wall heaters are ideal for small living areas.
Gas Wall Heater
Wall heaters were developed from radiators, which declined in use after the gas heater was introduced. Directly attached to walls, gas heaters permit the free flow of heat and are more economical than electric wall heaters. Early versions needed a ventilation system, which was unhealthy for some people; this was largely eliminated by the ventless gas wall heater.
