One of the most common questions homeowners and builders ask is whether rangehoods have to be ducted. In this article, we will delve into the world of rangehoods, exploring the different types, their functionalities, and the importance of ducting.
Introduction to Rangehoods
Rangehoods, also known as exhaust hoods, are appliances installed above cooking ranges or stoves to capture and remove airborne pollutants. They are an essential component of any kitchen, as they help to eliminate cooking fumes, grease particles, and moisture. Rangehoods can be categorized into several types, including ducted, ductless, and convertible models. Each type has its unique characteristics, advantages, and installation requirements.
Types of Rangehoods
Understanding the different types of rangehoods is crucial in determining whether they need to be ducted. The primary distinction lies in how they handle the extracted air.
- Ducted rangehoods are connected to a duct system that vents the air outside the house. This type is considered the most effective in removing pollutants and moisture from the kitchen.
- Ductless rangehoods, on the other hand, recirculate the air back into the kitchen after filtering it. They are more suitable for kitchens where ducting is not feasible.
- Convertible rangehoods offer the flexibility of being used in both ducted and ductless configurations, providing homeowners with more installation options.
Importance of Ducting
Ducting is a critical aspect of rangehood installation, especially for ducted models. Proper ducting ensures that the pollutants and moisture extracted by the rangehood are vented outside, thereby preventing their recirculation into the kitchen. This is particularly important for maintaining good indoor air quality and preventing the accumulation of grease and moisture, which can lead to mold growth and other issues.
Do Rangehoods Have to be Ducted?
The question of whether rangehoods must be ducted depends on several factors, including the type of rangehood, local building codes, and personal preference. In many jurisdictions, building codes require rangehoods to be ducted to the outside to ensure that kitchens meet certain standards of ventilation and air quality. However, there are scenarios where ductless rangehoods might be acceptable or even preferred.
Scenarios for Ductless Rangehoods
While ducted rangehoods are generally recommended for their effectiveness, there are situations where ductless models might be more appropriate:
- Historical Buildings or Apartments: In older buildings or apartments where ducting is not feasible due to structural limitations, ductless rangehoods can provide a viable alternative.
- Island or Peninsula Cooktops: For cooktops located in islands or peninsulas, ducting might not be practical. In such cases, ductless rangehoods can offer a solution.
- Temporary or Rental Properties: In situations where a permanent ducting installation is not desired, such as in rental properties, ductless rangehoods can be a convenient option.
Considerations for Ducted Rangehoods
For those opting for ducted rangehoods, several considerations must be taken into account to ensure effective and safe operation:
- Duct Material and Size: The duct should be made of a durable, non-combustible material and be of the appropriate size to handle the airflow from the rangehood.
- Duct Route and Venting: The duct should be routed in a way that minimizes bends and obstructions, and it should vent directly to the outside, avoiding attics or crawl spaces.
- Regular Maintenance: Ducts should be regularly inspected and cleaned to prevent the buildup of grease and debris, which can lead to fires or reduce the rangehood’s efficiency.
Conclusion
In conclusion, whether rangehoods have to be ducted depends on various factors, including local regulations, the type of rangehood, and specific kitchen conditions.
