Underfloor ventilation for hob extractor on Island

[Dave Jones]

this is my biggest regret on our build. Island hob with pop up recirc.

 

Wish I had taken the air tightness hit and ducted it out under the block and beam. Will definitely do this next time.

 

We have MVHR but you dont want to fill the ductwork with kitchen stink, especially greasy type stink.

We have recirculation hob extractor. But we placed the kitchen MVHR extract as far away from the hob as we could. We have a white foam filter sock on the terminal, it only ever has dust in it, never greasy. Ventilation extract position it as important anything else.

 

This is the inside and outside of the sock after 6 to 8 months

ours is the same. im amazed just how filthy the main MVHR filters get. i swop them monthly.
