Range Hood Flues

So your finally updating your kitchen and have probably come across a few additional expenses that you had not considered and now your plumber is asking you if you want your range hood to vent to the atmosphere or recycle and your not even sure exactly what the difference is.

What’s the difference?

A range hood is the extraction fan installed above your cooktop which helps remove the cooking steam and smells and if your using gas, the combusted gas fumes.

In simple terms, there are two types of range hood systems. Recycled air and vented to atmosphere.

Recycled air range hoods suck the air from above your cooktop and push it through a charcoal filter before returning the air to the kitchen. The charcoal filter helps remove smells and moisture from the air and should be cleaned and serviced on a regular basis.
Benefits – Cheap installation costs
Con’s – requires more ongoing maintenance and does not remove 100% of the smell or moisture. Where gas cooktops are used, the burnt flu gases are returned to the house.

Flued to Atmosphere Rangehoods suck the air from above your cooktop and pushes it through a flu pipe that disposes of the dirty air to outside either through the roof or wall. From our experience, this is One of the most underestimated plumbing costs that customers have. The reason for this is the cost of flu pipe, bends, terminations, lead flashings and rubber boots for penetrating the roof all add up fairly quickly. This compiled with the fact that it takes several hours labour for the installation and pending on the roof layout, may require the use of harnesses and a second person to be on site.
Advantages – maintains high quality clean air in your home as all cooking steam and burnt gas is disposed of permanently. Lower maintenance as they don’t have filters that require servicing and replacing (note they do have prescreens which should be kept clean).
Disadvantages – as mentioned, cost can sometimes be an inhibitor. In a best case scenario, a standard installation will cost over $550, and could be more than this pending on the size required and if additional offsets or complications are required. Can I just run a vented ranghood into my roof space?

Can I just run a vented ranghood into my roof space?

This is a question we get asked a lot, and no, we do not recommend this. Fats will build up in your roof space causing a fire hazard directly above the most likely place a fire will start.

Can I use the old flu pipe?

Maybe – If the size of the existing rangehood flu pipe is equal to the new flu pipe than with some slight modifications you will probably be able to reuse the existing flu including its penotration and flashing. If the existing flu pipe is smaller than the new flu pipe we do not recommend using it. It will put additional strain on the fan and likely void your warranty.

We recommend discussing the two options with your plumber prior to purchasing your rangehood and organising for quotes and work to take place.

    From my first conversation with Tom, I was treated in a very professional manner. The quote I was given was fair. Nathan and Aaron were two polite young men who dealt with my plumbing problem promptly and expertly, leaving my house so clean. Excellent workmanship and customer care. I highly recommend Water Tight Canberra. Thank you!!

    We have been chasing a plumber for months in Canberra, when today we saw Water tight in their van at a neighbor. One call and the wonderful receptionist organised for Aaron to come over in his Lunch and fix our major shower blockage. What can I say, OMG!!! This is service, Aaron would not settle for anything less than perfection. Pulled the shower apart, explained in detail to me everything that was happening and found the annoying problem. A old piece of plastic off the washer stuck in the pipe. He even gave me great advice on our toilet issues and over pressure issues. Unbelievable service, more intent on fixing the problem and doing it right than ripping us off. I wholeheartedly recommend Water Tight Canberra and especially Aaron as the no 1 plumbing service in Australia.

    I arrived at my townhouse on a Friday afternoon at about 1:30 after a week away to find that the hot water service had sprung a leak during my absence. I called Water Tight and a representative (Tom) was here within an hour. After an inspection and quotation Tom undertook to replace the HWS that day and did so with two other members of staff. I was very favourably impressed with the prompt and efficient service. I would recommend Water Tight to anyone with an urgent plumbing problem.

    Water Tight provided an excellent job on 25/02/2019. They located the burst water pipe and repaired it immediately. We are so happy with the great service and the professional crew. I strongly recommend this company for any plumbing need that you have.
