Extractor fan for oven in chimney breast

Jcqlou

Hi everyone,

I've been looking on this site for an answer to my current kitchen issue but to no avail unfortunately, so thought it would be best to create an account and ask for advice.

We bought our first home in February this year and we're planning to renovate the kitchen. There's a chimney breast in the kitchen which housed the old coal boiler which we have now replaced with a combi boiler. We were planning on placing a range cooker into the now empty chimney breast but the extraction is where we're a bit lost. Our initial plan was to extract up the chimney but I've read about issues about grease building up due to the height of the chimney and extractor fans not being able to adequately push the cooking fumes up.

The chimney is also no where near an external wall so we're stuck with that option as well.

Is there a possibility that we could extract upwards like it has previously been done when the coal boiler lived there?

Any advice on the best option for extraction would be much appreciated!

Thanks in advance and apologies for long post.

You could look into electric chimney fans which are fitted on top of the chimney and should offer a strong airflow. Perhaps one of those either alone or in combination with a conventional extractor hood in the kitchen. You could then include grease filters in the extractor hood which would avoid the problem of grease coating the inside of the ducting.

Thanks very much for the reply, much appreciated!

It is possible to use the existing chimney but it needs to be lined with a flexi metal liner with a terminal/pot and a suitable fan housing adapted to fit. Dont think there is an off the shelf kit available.

Or consider a down draught hood unit (it works on recirculation via filters)

Fortunately, the liner only needs to be single skin, so is relatively cheap (around £10 per metre). An inline fan would work quite well, and are available in a number of sizes from 4" up to 12" - Depending on the height of the chimney, a 5" may be suitable. The OP would need to contact a manufacturer for advice based on the duct (flue liner) length and volume of air that needs to be shifted.

Ok I'm new to this site and I might be being really stupid but how do I start a new thread? Many thanks in advance

Hi all.
We have just bought and moved into a new house.
The party wall in our rear garden is the wall of the village shop. The owner has a 300 mm diameter fan blowing directly into our back garden to remove heat from all his refrigeration. It is very loud and noisy and also runs all night long. It ruins the back garden. I approached him about it today and he just said sorry but he couldn't turn it off as he has too much heat in the shop to deal with.
Can anyone advise me on this as I feel we may have to go down the legal route to resolve this as he seems quite unwilling to even talk about it. I was hoping to find a solution with him without all that but it's looking unlikely.
Thanks in advance:)

A. There's a New Thread button at the top of each forum.
B. Was the fan not there when you viewed the house?

A. Thanks

B. Yes it was but wasn't running. The council have told me it needed planning permission of which there has been none sought. A commercial premesis are not allowed to exhaust straight into a domestic property. I would like to help the shop owner find a solution to the heat from his refrigeration. The fan is doing very little to reduce the temperature in the shop which I know because we install commercial extraction as part of our services. He needs a HUGE fan to pull the sort of volume needed to make a difference. There is also multiple ceiling fans and a large floor standing fan running all the time. His electricity bill must be horrendous and he would be better to install Air -con and insulate it properly.It would reduce his electricity bills, make the shop more pleasant for customers and stop his refrigeration working so hard which would also reduce the heat.....
