Definition:
Supplementary heating: Supplementary heating refers to secondary heating sources utilized when the primary heating system is unable to meet the desired temperature requirements of a space. These additional heating methods, such as electric resistance heaters or heat pumps, are activated to provide extra warmth during extremely cold weather or when the main heating system is underperforming.
Additional Facts
- Supplemental Heating: Auxiliary heating systems are designed to kick in automatically when the primary heat source can’t meet the demand, often during extremely cold weather.
- Electric Resistance: Many heat pumps include built-in electric resistance coils as a backup heat source, providing quick and efficient supplemental warmth.
- Dual Fuel Systems: These setups combine a heat pump with a gas furnace, allowing for optimal efficiency by switching between the two based on outdoor temperatures.
- Space Heaters: Portable electric heaters can serve as a temporary solution for localized heating in specific rooms when the main system is insufficient.
- Radiant Panels: These can be installed in walls or ceilings to provide additional warmth through infrared radiation, complementing the primary heating system.
Fundamental Mechanisms
| Mechanism | Purpose | Key Components | Critical Issue | Impact of Failure |
|---|---|---|---|---|
| Electric Resistance Heaters | Provide supplemental heat when primary heating is insufficient | Heating elements, thermostat, safety controls | Burnout of heating elements | Inadequate heating, increased energy consumption |
| Radiant Floor Heating | Deliver warmth through floor surfaces for even heat distribution | Piping network, circulating pump, boiler | Leaks in piping system | Uneven heating, water damage, system shutdown |
| Ductless Mini-Split Heat Pumps | Provide zoned heating in specific areas | Indoor air handling unit, outdoor compressor, refrigerant lines | Refrigerant leaks | Reduced efficiency, inadequate heating, compressor damage |
| Baseboard Heaters | Offer localized heating along walls | Heating element, housing, thermostat | Dust accumulation and poor air circulation | Reduced heat output, fire hazard, increased energy use |
| Infrared Heaters | Provide targeted heating for specific areas or objects | Heating element, reflector, controls | Damage to heating element or reflector | Ineffective heating, increased energy consumption, potential fire risk |
