Kitchen Ventilation

DRP

Our hob isn't on an external wall, and we don't have the option of ducting.
We have a circulating extractor above the hob for smells, plus a wall extractor on an external wall about 4m away.

Not perfect, but as we have electric oven and induction hob there is, in theory, less moisture to deal with.

May I ask which type of extractor DRP; radial or centrifugal? How many air changes per hour does it achieve and do you find that adequate? Have you opted for a manual fan or is it controlled by a humidistat?

I'll come back into this 1. I can accept you aren't intending to go the hood route, (don't fully understand your reasons though), so;

I have a thing about condensation in bathrooms, ours is quite large and we do tend to splash the water about a bit.
I installed 2 massive extractors in 6mtr long room, a very large centrifugal inline unit with the grill over the shower and a 9" expelair roof mounted at the other end of the room.
The Expelair is very noisy, the inline unit almost inaudible.
Please don't ask the make, it was installed about 9 years ago and I haven't seen it since as it sits in the loft and has been trouble free.
It was expensive as it was rated for commercial properties, I think it took 200 mm hose
When used on it's own the over shower unit pulls so much air that it could be seen disrupting the condensation as it gushes in through the downlighters.
The expelair is thus rarely used.;)

Thank you, that is useful. I had become aware of the noise issue and think I need to aim at something which works below 25dB. The inline fan also sounds like a sensible idea but I'm not so sure I want my hair standing on end in the shower!

I think you are right to have a thing about condensation, cure that and most other things sort themselves. We have a 2.7 x 1.1 m fixed window on the stairs which ran with condensation all winter - to the extent that a previous owner had replaced the window sill with a piece of formica. The formica is gone now, along with the condensation following the installation of an external double glazed unit and allowance for air circulation around the internal window. The house is als a tad warmer!

I can check the model tonight, but tbh it is just a bog-standard bathroom extractor with a switch on the wall. To be honest we don't use it that often.

I'd guess you won't have an issue unless you do a lot of cooking that produces loads of steam, or have a damp or badly ventilated house.

I am quite paranoid about humidity/moisture so have several humidity meters in the house and have not noticed any issues (we are in the process of renovating a damp house, so I have keeping track of how much effect on RH our renovations are having).
