Whoa, lotsa questions and comments!
I've thought about installing the 1992 Superba dw there, or a hook-up for my WO-65 *whenever* it gets running properly ... but I'm not feeling an urgent need
at the moment for a plumbing project, LOL.
The kitchen is out the door and to the right, so a sink is nearby if needed.
Houses in the area are brick-veneer construction. The location is mile or so outside city limits so there's no city services or natural gas. Electric is it, or a propane tank.
200 amp service to the house, single phase. The tankless is rated 28.8 KW @ 240 volts. It has four 7,200 watt elements. Two 60 amp breakers in the main panel, and a "Supplementary Overcurrent Protection Assembly" panel with eight (single-pole) 40 amp breakers ganged in four groups of two.
Output temp range is adjustable 75°F to 140°F. No timer, it runs by demand. 0.4 GPM flow rate to trigger. TTH (time to hot) depends on distance to the point of use, same as with a traditional tank unit ... plus about 30 seconds for the elements to get fully going. There's an optional "performance" mode that supposedly gets it going a bit faster, but I didn't see an appreciable difference in practice.
The unit throttles the elements as needed to hit the target temp depending on incoming temp, desired outgoing temp, and flow-rate. The display can show instantaneous power demand as a percentage of full capacity. I have it set at 102°F for normal use (showering) and raise the temp as needed for tasks. Normally 115°F to 117°F for clothes, as the IWL12 controls to 115°F for warm. Sometimes I set it at 140°F for whites. Last time I did that, with a flow rate of ~2.3 GPM, demand was about 78% -- but ONLY while the water runs. No water flowing, no power used. Last time I filled one of the whirlpool tubs @ 112°F, demand was about 37%. I don't raise it for dishes, as the DishDrawer always heats main wash and final rinse to specific temps.
Water gets hot at the washer quickly. Kitchen takes longer than one expects, likely due to how the lines run. The master bath which is at the *far* other end of the house takes about 3 minutes, but that's at about 1 GPM flow rate (I don't crack the shower fully open to get it heated) and is totally a function of the distance. I've thought about adding a recirculation pump to run for getting it heated, but the water down the drain isn't
really wasted as it goes into the septic system then later sprays on the yard.
The large jar is (currently) Ariel OxyAzul.
The small jar is oxy-booster.
I was leery of the Floormate as I'd read on epinions that they don't suck so well, but it does OK. I've not yet tried wet scrubbing. I also have a Hoover Celebrity. The upright is a Singer, bought for $85 on close-out at Wal-Mart about 18 years ago.
The world map I've had for years, it fit the utility room color scheme, and the wall space!
Sheeesh. I wrote a book.
