I'm in the process of buying a 1950s ranch house. It doesn't have the greatest insulation, so I'm planning to do some improvements over the first few years to tighten things up. I'll certainly do the basics (expanding foam in window openings, gaskets behind outlet/switch covers, rigid foam sealed with expanding foam along the rim joists in the basement, an extra foot or more of insulation in the attic, rigid foam on the basement walls, new weatherstripping where needed). I live in Michigan, so we do have a real winter with snow, and a few days in the summer where it will get hot enough to turn on the AC, so anything to save money on energy bills is great.
I've been reading about the issues you can run into when you seal up a home TOO tight, such that you don't have enough fresh air in the house. I'm not sure I'm going to run into these, but then I'm not sure how good a job I'll be able to do with the above-mentioned improvements. If it comes to it, installing an Energy Recovery Ventilator or Heat Recovery Ventilator (ERV or HRV) is something that I would consider in the future.
All of this leads me to my main question: I like to cook. I would like to put in a fairly powerful range (nothing huge, though; I don't need six burners and a griddle), and will need a hood that can carry smoke, heat, steam, grease, etc. from cooking out of the house. I don't want absurd overkill, but I don't want my smoke detectors going off when I roast a chicken. It looks like I will be looking at hoods around 650-800 CFM (see my other question).
The air that goes out the hood has to come from somewhere. Will an HRV flow extra intake air if there is a pressure imbalance caused by extra air being exhausted elsewhere in the house? Will it flow enough extra intake air to supply the hood I'll need for the above? Chances are, I'm not going to have the hood on high unless I'm cooking something that produces a lot of heat/smoke, or cooking for lots of people (things I do regularly, but not every day). Would it OK to run the fan on low/medium most of the time, and open a window when I need to turn it up? Or do I need to look into providing dedicated make-up air?
Am I just over-thinking all of this and I'll be fine because there's no way I'll ever be able to seal an existing house up enough that this is a concern?
