What is a Rangehood Flue?

When updating the kitchen many homeowners have a difficult choice when it comes to the flue above the oven, especially if that oven is going to be replaced. In many cases, a flue like this will work in a number of different kitchen styles, but that is never guaranteed. The issue is that replacing this flue, known as the rangehood flue, can be quite pricey. Most homeowners look to keep what they have, yet this isn’t always possible.

Here we take a look at what these flues are all about, how they work and why they provide such a benefit in the kitchen.

 The Nuts and Bolts of a Rangehood Flue

In simple terms these flues are extraction fans, they use suction to remove any harmful fumes coming from the gas cooker below, they also work well at preventing smells from the cooking food, from circulating around the kitchen or the home. After all, there is nothing worse than frying up a steak in the kitchen, only for the house to smell of grease once you have finished. The rangehood flue will ensure that those smells are sucked away, leaving your kitchen and home smelling great.

Types of Rangehood Flue

If you look at rangehood flue kits to replace your existing flue, you will likely find two main options. The first option is a rangehood flue that recycles air, and the second is a flue that vents to the atmosphere. The first option here will suck air in and then force it through a charcoal filter, before sending that clean air back into the kitchen. The charcoal cleans the air and removes odors. This first option offers low installation costs, yet the filter will have to be replaced periodically.

The second option will suck the dirty air and send it through a hole in the wall or your roof, and out into the Earth’s atmosphere. Despite this appearing like it is a simpler option, the reality is that installation costs can be very high. This is owing to the invasive nature of creating the vent in the exterior of the property.

 Venting Into Roof Space

A lot of people think that they could potentially vent the air from the kitchen directly into the roof space, thinking that it will dissipate over time. This, however, could not be more wrong. If this kind of installation was done, it would mean that fat gradually builds up in the roof space over time, causing one hell of a fire hazard.

 Using Old Flue Pipe

In some cases, you may be able to purchase a rangehood flue kit that will be able to utilize your old flue pipe. This, however, can only work if the fitting for the new rangehood flue is identical to the old one. If it is not then the connection will not be flush and you will end up with a leak of fumes.

These are critically important pieces of kit in the kitchen but it is important that you factor them in when you decide to renovate that space. The preferred and lowest price option is that you are able to keep your old rangehood flue.
