Hi, I am installing a whole house MVHR but I not impressed with the idea of using a recirculating cooker hood, especially when cooking strong smelling foods such as currys etc. Recirculating hoods only work to a point and the thought of spreading pungent cooking smells through the whole house is a no no.. I have been looking at a couple of options to give me a separate external vented Cooker hood. I option is to build a motorised airtight damper into the round ducting network. The damper is opened as the fan is turned on and subsequently closes when extractor is turned off. Another Interesting idea I have seen is the Luxair automatic airtight vent which opens when there is a pressure of above 150Pa, I.e fan is on speed 1, then closes to give a airtight seal again. If I used either option I would turn off MVHR and kitchen extract only for cooking period then turn MVHR back on. General daily living such as boiling veg and steam from kettle i would just use MVHR ventilation. Has any one used these solutions along with their MVHR, or come up with other solutions other than cooking curry out in the garden https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F381900534260 (motorised damper link) https://luxairhoods.com/kitchen-extractor-hoods-ducting-and-vents/Airtight-Ducting-System-Kits
