Extractor fan and HRV

Effects · 16-09-2017 10:58AM #1

I'm looking for advice on a cooker extractor for a house with HRV system.
I don't really like the option of a recirculation fan myself.
I was thinking of putting in an actuator to open and close the duct when the extractor is on.
The engineer has advised against this and said to stick with a recirculation fan to avoid grease buildup on the actuator. Won't the grease that doesn't go into the duct just spread around my kitchen and living area if I go with recirculation?

Any feedback on this? Architect is pushing me to make a decision drill the hole to the outside.
I'm leaning towards getting the external ducting in place. Goes against the engineer's thinking but various engineers have made various mistakes on the project already so I'm open to other peoples thoughts.

This is the type of unit I'm looking at:

Get a recirculating hood. The filters can remove smells and grease although not as good as a extractor it's still more that good enough. This way you're keeping your house airtight and not throwing heated air outside or upsetting the balance of the heat recovery unit.

The hoods I'm looking at have both options. I've never found recirculation hoods great in the past.
I'll think I'll stick with it for now and then I can always vent it to the outside at a later date.

I have one. Find it very good. Also have HRV installed.
