Types Of Whole House Fans
Whole house fans are a central appliance in your home's HVAC system, and provide consistent and effective ventilation for every room in your house. However, there are three main types of whole house fans on the market, each of which provides the same ventilating function but carries a distinct set of benefits and drawbacks. Understanding the differences between the characteristics of the different variants of whole house fans can help you choose the one that best fits your home's HVAC needs.
Large Diameter Whole House Fans
Large diameter whole house fans, like their name would suggest, have a wide opening with large fan blades that allow for a massive amount of air to flow through the fan when it is turned on. This makes large diameter whole house fans the ideal choice for homeowners who live in warmer climates and who require a high degree of cooling.
However, due to the size of large diameter whole house fans means that it can be hard to find a place to install them, depending on the layout of your roof. Further, these fans need to be sealed every winter to prevent heat loss and water damage, which increases your long run maintenance commitments.
Insulated Door Whole House Fans
Like the name would suggest, insulated door whole house fans are designed with an insulated covering that can be closed. This makes this type of whole house fan ideal for installation in areas that suffer from severe winters, as they prevent heat loss through the fan opening once the temperature drops below freezing. This has the inverse benefit of maintaining the temperature within your home when you are running the air conditioning and not the fan, as heat will be unable to seep through the insulated doors.
The major drawback of these types of whole house fans is that they represent an increased expense over standard whole house fans, both in terms of material costs and installation.
Inline Whole House Fans
Inline whole house fans are the budget ventilation option. The most affordable fan installation available on the market, inline fans make use of a small section of insulated ductwork to move air. This makes them extremely flexible in the installation process, allowing you to install them in individual rooms as needed.
Inline whole house fans are actually a misnomer: while they can provide increased air flow and cooling in multiple rooms, they tend to be too small to actually move air throughout an entire home. You'd have to install multiple inline fans in order to get the proper air flow. For more information, contact companies like A & E Heating and AC Inc.
