Advantages of Forced Warm Air Heating System (FWA)

The advantages of (FWA) forced-warm-air heating system are as follows:
- Lower installation costs than those for hot water or steam heating systems.
- Heat delivery is usually quicker than in other heating systems.
- Heat delivery can be shut off immediately.
- Air filters replacement is easier, cheaper and quicker than maintenance for other types of heating systems.
- Humidity level of the air can be controlled more easily.
- Air conditioning can be added without incurring great expenses.
- Furnace can be placed in a number of different locations in a building structure.

Disadvantages of (FWA) forced-warm-air heating system are as follows:
- Noise: Both the operation of the blower and the expansion and contraction of the ducts as the air temperature rises or falls can cause distracting noise.
- Furniture placement and room decorating problems: in order to operate effectively, furniture or carpets should not block warm-air outlets. This restricts furniture arrangement and placement of carpets.
- Dust: Ordinary filters remove larger dust particles, but are not very effective against the smaller ones. High air turbulence results in dust deposits on walls, furniture, and other surfaces.
- Various room temperatures: Forced-warm air heating systems supply convected heat through forced-air movements, which results in bursts, when the thermostat temperature is adjusted, rather than continuous steady flow. Temperature variations can be reduced if by setting the fan switch for continuous blower operation.
