Got a surprise call from Jordan:
He bought a 5gpm electric tankless water heater because it was a really good deal at only around $400, while 6gpm or higher doubles or more the price. I thought it sounded good, having checked online
http://learn.compactappliance.com/tankless-water-heater-sizing/
that seems to show a shower can run easily with 2-3 appliances going at the same time...when will that ever happen?

He also explained a bit more about the hvac guy's conclusions - he said running a return from the main floor was a bad idea, but the ductwork was still good as supply to get the main floor cool. They're moving the return from the closet / over the stairs to the same area but "around the corner," which I think means on the hall wall (also much easier to access, which I hadn't thought of) (duh). Curiously the other comment was that the a/c is overpowered in the master bedroom if we use the 2 vents in there now. 3 vents should be fine for the main floor (but not with an intake). I'm sad to lose the intake because it would eat dust - but taking air from the lowest part of the house for cycling into the a/c is a bad idea.

They're having problems with the doors - the supplier isn't being responsive. He thinks as they screwed up another job they probably screwed this one up and are working to get the right doors prior to taking his call. Or it's xmas.

He asked when I'd be delivering the faucets I got, guess that's tomorrow.

He also noted he thinks the kitchen cabinets are probably going to be going in around the time the hvac guy is there, Jan 4.

He also noted not to worry about what I see with the drywall around the stairs - there was some kind of miscommunication. There have been 4-5 guys working there at once.

The stairs for the front steps to the basement were framed in and about ready, but this rain pushes that back.

They passed inspection in the basement on Friday.

Saga continues.

Update: 12/25 (home sick still)
Visited the place with Veronica (yesterday).
The drywall issue may be that they drywalled the closet under the stairs now that the stairs are complete. However they also, reasonably I would think, drywalled all sides - when one side will be open as doors are put in for under-the-stairs Harry storage space. So the confusion or concern might have been whether the extra closet doors/drawers was scrapped.
Also, did I mention the stairs are complete? I think they're pretty.
Forgot to mention they've also sanded most of the wood around the stairs and bannister.

Every time I visit the place it's more gorgeous. It's more than I ever thought about when I bought the place. Not sure...I think I'm kinda ghetto so it's not clear I'll actually appreciate a lot of the changes. I think the master bath and laundry is a huge plus though. The space is nice.

One struggle is where to put my pinball machine and her piano.

I had a tankless in Dupont - I went that way because the only location for a tank was under my kitchen countertop, which was unacceptable (I'd have to rip the kitchen apart every time I had to replace the hot water heater).

I was happy with the tankless for the most part - I want to say that mine was significantly less than 5GPM - I couldn't run anything else if I was showering, but that was fine. Be aware that in the winter, you'll get away with running less appliances at once if you want truly hot water - the colder water takes more work to heat, resulting in a lower total volume of hot water.

Other nice thing about them, when they fail, they don't dump a ton of water all over the place - much less collateral damage. It used to be hard to find people to service and install, but I think tankless heaters are much more common now than they were a decade ago.

Thanks - yeah they are a lot more common, even than when I started this project. I was going to use tanks but...the price difference and having new things? Seemed obvious.

I also heart the little space it takes up.

From your link:
Other Sizing Notes

Gas tankless water heaters are able to produce a larger temperature rise per gpm than electric models. Most demand water heaters are rated for a variety of inlet temperatures. Typically, a 70°F water temperature rise is possible at a flow rate of 5 gallons per minute through gas-fired demand water heaters and 2 gallons per minute through electric ones.


This seems to strongly imply that a 5gpm electric tankless might not be able to raise the temperature of the water to something comfortable. You might want to get clarification on that point before agreeing to the installation.

Well good point. Water lines are underground, and while water is colder in the winter, even at 30 deg a rise of 70 deg gets it to 100. But if reduced to only 2 gpm, then only 1 thing could run at a time full blast, true.

(I'd assume the water coming in through your pipelines is at least 33 degrees.....if not, you've got a big problem)
