Welcome to the forum if this is your first posting. Very nice layout. Your choice for water flow is borderline for a falls that high. Refer to the pump flow chart either in the directions or on the Manufacturer's website. Figure every 10 feet of hose equals 1 foot of elevation when you begin to determine how much water is actually flowing out of the falls. Always use the next size hose for better flow. Always better to think there is too much than to think, "Oh I should have gotten the bigger pump". You can always divert the flow. Elbows also decrease efficiency. For a really nice display go for a 2x capacity even 3x. It is all a matter of taste and what effect you are trying to achieve. You can trip the water rushing down the falls with a bowling ball boulder at the bottom or force the turbulance down to the bottom of the pond to keep the layers of the water column moving and mixing. Add more rocks on the falls to change the tones. You'll have massive air exchange on the falls. The water will release CO2, and gain O2, thus helping keep a balance. That's a good thing for a well planted pond and any pond for that matter. -Philip

Make the wall cabinets 3" smaller and it should be fine. As to BTU, you can still get a sear on steaks, but you will probably need to do them one at a time using something like a cast iron pan that has a lot of thermal mass to keep the heat drop from being so precipitous. As to what is "enough", it depends. Many people find themselves cooking more in their new kitchens. It's always easier to turn a burner down than to wish you had more power that isn't there. You should take a trip to a local appliance showroom that has a few ranges set up to be able to test drive. See what you think you need, based on what you cook now. Then, go one step up in power if you can afford it. The BTU power game costs money to play. So, if you rarely do stir frys or sear a steak on top of the stove, you can probably adapt to doing it in smaller batches. If either of those things is a frequent activity, you should really put some testers through their paces before making a decision. But, also remember that more BTU's means more CFM's needed for venting. And that can trigger makeup air needs. A lot of people do a lot of their high heat cooking on an exterior grill because it's easier to get the results that they want without having to deal with the smoke and grease in their kitchens. If you go "good enough" for inside the house, you might want a good grill for the patio next to the kitchen so you can have the best of both worlds accessible to you.

Personally, I would get someone to look at your house and price out these options for you. Browns Heating & Cooling does estimates and they have packages and guarantees that allow you to be flexible, get great service, and it's affordable. They are in New Jersey, so if you are in the are, definitely give them a call. Good luck! Here is a link that might be useful: Brown's Heating & Cooling

Ron, everything you say is correct, except, full description: The power comes from the street on an overhead line to a pole on my property with a transformer. From the transformer, the service goes down the pole underground to a meter stand about 50 feet away, where the meter and cutoff switch are located; this was all done by the POCO. Initially, it was a 200 Amp meter with a 200 Amp underground service to my house, about 180 feet away. At that time, there was also a receptacle mounted on the meter stand (and, I assume, a breaker somewhere). When they discovered their mistake, the meter was changed to a 400 Amp meter and a second 200 Amp underground service ran to the second 200 load center, which now services primarily my boiler. I got my CO after all this was done. My initial plan for a generator was to locate it next to he meter stand, so I had a large propane tank installed nearby with a line, again underground, to the house where it services my gas cooktop only. My thought was to put a generator near the propane tank and feed it to one or both of the services which start at the meter panel. These ideas were all approved in principle by the builder and his electrician. If this generator were to feed only the second 200 Amp line, I might move my more essential circuits from the first load center to the second. Last December, I had solar panels installed. The very professional installer ran his line from the roof down to just outside my utility room, in to the two inverters in that room, then to two cutoff switches (one outside), to the second load center. I discussed this whole thing with him and he suggested I consider one or two Tesla Power Walls (Tesla was NOT involved with the solar installation).
