A 42” Kobe. Plus the separate make up air system based on your HVAC engineer’s calculations. .

Will have to talk to the HVAC people about make up air.

Thank you!

We just went with BEST the brand. It was under a thousand and we're told that we would be able to easily cook a steak indoors with it. Maybe check out their options? They sell them a lot of places.

Thanks! I’ll check them out!

Performance, aesthetics, affordability -- pick two or trade among them, but your qualitative performance requirements list does not lend itself to low cost. You very much need to read hood and MUA threads here to gain understanding of derived requirements and how they affect choice of hardware.

I rarely recommend a commercial system like ours but for for your requirements you need as efficient of effluent removal as possible with the least amount of air being exhausted (and made up). Consumer hoods will not achieve that.

Thanks @opaone! Those were extremely helpful reads!

I decided on a Proline in a similar build (near Passivehouse, induction). not in yet - but we've tested the unit and it seems reasonably quiet andthat's before any muffler / dampener. The interior baffles are well done / dishwasher safe.

Not leaking air is a function of sealing the ductwork and a good damper. I also order my exterior vents / shields from FAMCO - as they have a nice custom product.

If you are near passive - you can design your HVAC with the approrpiate HRV / ERV that will cover your makeup air requirements and work to control with the hood. (we have 2 - one general, one specifically for bathroom exhaust)

"If you are near passive - you can design your HVAC with the approrpiate HRV / ERV that will cover your makeup air requirements"

HRV/ERV's do not and cannot provide MUA*. They are balanced systems only. OP (and @just_janni) will need an appropriate powered MUA that matches the exhaust CFM's of the range hood.

Putting something like a Proline in a PH, NPH or even PGH is a poor plan. It's like spending $10 to be energy efficient and then wasting $7 of it with wasted energy in an attempt to save $1 on the hood and then having poor IAQ and health impacts as well.

In most climates the ideal for PH/NPH is recirc but we now know that recirc results in poor IAQ and so health problems for occupants. You need to exhaust as much effluent as possible with as little air exhange and energy as possible. To do that you need a large open capture area and a large containment area - something that Proline and other consumer hoods lack.

A commercial hood such as from Accurex will provide for much better effluent removal for lower CFM's (and be much quieter as well).

* An HRV/ERV can (and should in a PH/NPH/PGH) provide bathroom (and laundry room or similar) exhaust. Note that this is a balanced exhaust system and not an MUA.

^^ fair point - will have to provide additional makeup air. I didn't have desire to do a commercial hood and no combustion in conditioned space which allows a little more flexibility.

Everything is a tradeoff.

Indeed, lots of tradeoffs!

With a PH/NPH/PGH you want enough air in/out to maintain healthy IAQ (CO2 below 500-700, VOC's low, etc.) but no more or as little more as possible. Any air exhausted is always made up for in some way (intentional MUA is best but otherwise it will find cracks and other ways to fill the vacuum). ALL of the air brought in must be or will be conditioned (heated/cooled/humidified/dehumidified/filtered) and that uses energy and so begins to defeat a key purpose of a PH/NPH/PGH.

So to spend money on the envelope (which I strongly support) but then not manage airflows defeats the purpose.

Consumer hoods require very high CFM's to function well and that's a huge waste of energy. Commercial hoods can accomplish the same effluent removal or better for far less CFM's, energy and noise.

@opaone raises an important point that I'd like to expand upon. Commercial hood operation and its MUA support is one of the highest cost activities for commercial kitchens. The hoods run for long durations, and often require air conditioned make-up air, at least into any restaurant customer area where the pressure is set a tad higher to keep out kitchen odors. Commercial systems are thus designed for power efficiency.

In residences, the hoods are operated for shorter periods of time, and typically (where MUA is nearly free) the cost of operation is small in the overall household power budget. Affordability then tends to be a matter of capital cost -- buying the hood, blower, ducting, and its MUA counterpart components and installing them. Striving for power efficiency through higher capital costs will take a very long time to pay off. Also, typical residential kitchens are ill suited aesthetically and space-wise for incorporating commercial hoods.

The intermediate case is where the household is subject to stringent air quality requirements that cannot be met by just fresh air exchange. In such as case, treating MUA can be expensive, and the requirement for almost total cooking plume removal requires a large hood, high flow rate, and a lot of MUA. Here, commercial or quasi-commercial systems like opaone has incorporated may be optimal from an overall cost and performance point of view.
