Thank you graywings and redbazel for your input. I just wish I could install the floors first and wait a month before painting but then it would be so difficult to move them again since they must be emptied and I don't want my floors scratched. I want a happy color on the wall that is very neutral and will not compete with my new floors and will also be easy to work in that is not so white as the Linen White. I will go get a deck of Aura Paint chips and see what is similar to Bone White but maybe nicer? I would like to try a paint that does not outgas for as long as the BM Pearl Finish Paint that I used. BM Bone White in my family room is warm and everyone loves the color but I have a lot of light in that room. I wonder if it would look nice in the office. I learned that even trying samples on the wall or sample boards does not tell the whole story until the paint is on the wall and the furniture is back in the room. I wish the painter would have painted behind all the cabinets and did a good job since then I would just leave things alone for a year but I think now is the time to paint since the cabinets are heavy and I do not want to scratch my floors by waiting at a later time. The only problem is then I will have to allow several days after the paint job to install the wood so the room can be acclimated with less moisture from the latex paint.

mike_home: my heat pumps are 4 ton units each; I went with slightly oversized air handlers. callights: Thanks for the tip on water temp, I will check on that, too. FYI, not sure if it's a clue but I am using the boiler for home hot water (showers) via indirect zone, and the boiler is maintaining I 150-170 degrees when the hydronic calls. HVAC support were prompt and helpful via phone; I told them to hold off sending someone onsite until I've gathered more data (plus they were dealing with folks who had NO heat last weekend, much worse off than I). With respect to gathering data, here's the latest: I've ended up setting the hydronic cfm to 1350; at that it looks like the system can maintain house at 68-70 if I wish...although wouldn't you know it the temp is now 50 degrees higher here in New England! Guess I need to wait for next cold snap for next test, but I suspect it's still not calibrated perfectly because it did seem to have trouble getting up over 70 degrees that cold day (after the cfm increase)...and no, I don't want my home at 72, it was just a test to see if hydronic could make that happen. Should I worry if it can only get up to 69/70 on a sub-zero-F day (as an indicator of some issue)? The VR1-40 is rated at 120-140K BTU, surely that's enough for a house my size?

There are closet systems available that don't touch the floor ... they hang on a track on the wall (Easy Closets is one maker). I wasn't aware that other floor-mounted systems required being nailed or screwed to the floor; I thought they were secured to the walls. I had sliding closet doors (triple doors) that hung freely from a track at the top and had no attachments to the flooring at all.

If the manufacturer allows nail/staple down installation of their engineered floor, that should be sufficient. Since your selection is NOT wider than 7.5", the warranty is valid. They won't address any issues with movement or squeaking though. I can imagine there may be a little more sound emanating from the floor but that would be acceptable to me, especially if one considers what would have to be done if your floor was damaged and required removal after being glued and nailed. If I was going to glue the floor down with a full spread adhesive, I see no advantage to nail/staple it also. For a better underlayment I would recommend Aquabar B, which is carried by Home Depot. https://www.homedepot.com/p/Fortifiber-500-sq-ft-36-in-Wide-x-167-ft-Long-x-7-mil-Thick-Aquabar-B-Tile-Underlayment-Roll-70-195/202592567?mtc=SEM-VF-F_D23-G-D23-23_6_FLOOR_AND_WALL_TILE-Multi-NA-NA-DSA-2150536-WF-New_Engen&cm_mmc=SEM-VF-F_D23-G-D23-23_6_FLOOR_AND_WALL_TILE-Multi-NA-NA-DSA-2150536-WF-New_Engen-71700000077168191-58700006540356281-39700059170875303&gclid=Cj0KCQjwhr2FBhDbARIsACjwLo33OGF8tiZIs8wUOKWMZ1XxG1JDAIsLbwsMH82Ahl0cZp9ethZdDe4aAsqZEALw_wcB&gclsrc=aw.ds#!bvstate=ct:r/pg:2/st:p/id:202592567
