Kitchen extractor and stove...same room?

Do the regs actually name a year rather than an air permeability number? That would be fairly ridiculous - so many new houses are plasterboard tents.

Yes both a year and a air permeability number, I think from 2008 new builds were pressure tested and leaked less air into them plasterboard or not.Big extractor fan on door, bit of a joke really as after the test other jobs are carried out which can remove the sealant stopping the leaks.

Non room sealed stoves can be a huge benefit they draw fresh air into properties during the colder months helping reduce condensation where windows are not opened, especially a benefit to older properties with solid cold walls.

First, they only do this when they are on. The rest of the time heated air is escaping through the stove, making the house colder and so worsening condensation.

Second even if they do this when on it is appalling to be dragging cold air through the house in such an uncontrolled manner. Houses should be ventilated properly, it should not be left to chance.

Not quite. Only 1/4 of each dwelling of each type on a development are tested and the actual requirement is very poor - 10m³/(h.m²). Many houses built prior to the advent of plasterboard and dot and dab achieve that, as do older wet plastered houses so long as nothing too egregious has been done.

Lots of reports of distinctly dodgy testing practice as well. It'll be a future PPI style scandal mark my words!

We have recently renovated our bungalow and have a 'hole-in-the-wall woodburner, an extractor hood and a boiler, all in the same room. We also have a patio door and two other windows in the same room. Might it be best to open the smaller window, which is next to the boiler, slightly when using the woodburner?

We have another woodburner in a different room also.

Define "best"! The physics are extremely complicated and you need to define your goal.

Well people in here seem to think that there will not be enough air for the woodburner if there is a cooker extractor there too, so I'm asking if it i a good idea to open the small window to allow better burning?

i have a 12kw stove in the kitchen. free flow vent supplying fresh air also have an additional adjustable through wall vent i mainly use for when cooking/when its hot, i put this in myself, so two vents in total.it makes a lot of difference in summer making the room cooler/fresher.in winter it makes almost no difference in temperature of room unless im silly enough to have it not running when its freezing cold.wouldnt reccomend any kind of extraction system in same room as stove,cooker hood or extractor

It really depends on your house, there's no such thing as an average house. Do you have a problem burning currently? Of not I wouldn't bother.

We haven't actually moved in yet and have only just had the stoves fitted. Hopefully they will be fine then

It's a two-bedroomed bungalow. I think we may be toasty warm!
