Reddit Community Insights on Electric Heating Costs:
Community discussions reveal important context for PTC heater positioning. One user noted that "almost all heaters are the same 1500W due to the 15A plug limit. So at $0.20/kWh, they will be 30 cents an hour. They are good for small places and instant warming up" [15]. This highlights that while PTC technology offers efficiency advantages, the fundamental power limitations of standard outlets constrain maximum output across all portable electric heaters.
Another important perspective from HVAC discussions: "If your heating is straight electric heat strips, those are not particularly energy efficient. If you have a heat pump, it may not be working correctly causing your emergency/backup heat, which is commonly those electric heat strips, to run constantly" [16]. This suggests PTC heaters are best positioned as supplemental or zone heating solutions rather than primary whole-home heating systems.
