Hot water recovery?

While looking over some other things, the notion of an heat exchanger came up.  Oh, well, ya, I know about such things.  First, it has been a long time since such things were a thought.  Second, it takes a bit of time to get settled in, before getting on to things.  And finally, I have enough on my plate for the moment.  However, the idea is there.  The price is fairly steep, up front.  I really wasn't sure that it could pay for itself, for me, alone.  Still, with little else to do, and no energy to do much on top of that, I decided to dig around.  I found an idea that might make such a project much less expensive up front.

Does it work as well?  Would the savings be worth the risk?  It seems like a decent project.  It is relatively simple.  It would add value to the home...  And it would be something to do.  Even over time, depending on the costs.  It's not like copper devalues, or becomes less functional, as with trying to buy computer components over time...  Oh, just... thought it was a snazzy notion and wanted to share it out.  Here is the diy, start to stop, heat exchanger.  I would be curious as to what you real diy'ers, or others who have had such a device installed, think about the worth of the project.

Can't tell the guy doing it is Canadian, or maybe hard northern US, can you?  *chuckles*  Oh, no bothers.  Just a little continental ribbing, mind you.

Installing a kitchen faucet.  Yes, there were things I did not know.  No, I did not read the instructions last time.  This time I will, and I will have the right stuff for it.  *scribbles*


One last video.  A bit of digging on installing a toilet and that doesn't look to be as much fuss as my imagination might have suggested.  Some bits I had read were not really well written.  Seeing it done makes a world of difference.

Oh... I did a bit of checking, locally.  I hadn't seen Toto when I went to the big boxes, so I didn't think to check with them.  A quick look and... it almost looked as if they are offering it at the same price as Amazon.  On top of that, Amazon's supplier hasn't even started the shipment and suggests it may take a month or more.  No, that won't work.  I don't know if I can cancel the order, but...  I want to make absolutely certain the box store isn't, like the other store, just offering one part of the toilet.  A bowl, or tank, alone, simply will not do.

Just... sharing my efforts.  Later...  Hmm, maybe a bite to eat and I might try to hit it.  Good night.

Oh... it does look like the box store has a slightly better price, and also delivers to my home, but in 4-7 days, not a month or more.  I tried to cancel with Amazon, but it looks like the seller is playing hard and fast and trying to avoid a cancellation (in spite of not even having processed the order yet).  I have contacted them, and will be contacting Amazon, as soon as I figure out how.  Gah!  Once confirmed I will order locally.  A month?  No thank you.

Well?  I tried to cancel, but their "system" was having a "problem".  So I contacted them through another means.  The order hasn't even been processed, and they don't think it will be until the 28th at the earliest.  They had best cancel!  Further, I contacted Amazon through the chat channel, asking them to make sure this company cancels, describing the problem canceling through the system set up for that.  I hate it when I feel trapped.  I got them to agree to contact the company.  I also suggested they let this company know that I have copies and such of the communications, which are time-stamped.  Some companies try to play fast and loose, that's all I'm saying.  As such, I went ahead and ordered through the big box, online.  Home delivery in less than a week, plus $40 less?  It's as good as I can do.  Now, to cross my fingers and hope the rest of it works out.
