In what contexts are portable space heaters explicitly discouraged?

Portable space heaters are explicitly discouraged in the context of installation for HVAC compliance due to safety and efficiency concerns. When a building’s heating, ventilation, and air conditioning (HVAC) system is designed and installed, it is engineered to meet specific heating requirements for the entire space. Relying on portable heaters can lead to inadequate heating, uneven temperatures, and potential safety hazards, as these devices may not be suitable for continuous use or designed to operate in conjunction with a central system.

In settings where HVAC compliance is essential, using portable heaters undermines the effectiveness of the installed system and can create risks such as overheating, increased fire hazard, and excessive energy consumption. Proper HVAC installations consider the overall heating load and airflow, and the introduction of portable heaters can lead to inefficiencies and possible violations of mechanical codes, which prioritize safe and effective heating solutions throughout the building.
