AC, verrrry jealous of that one. It looks like exactly what I want! It seems that heat pumps are much more common in your area than mine. Searching Craigslist near me I got nothin far as heat pumps go.

Search for Air Conditioners (try the Free section too)... that's what Acuario did... he used air conditioners.

Was interesting.. The install manual accidentally created an On-Demand rig..
"The problem with the above installation is when your heat pump
is running and you take a shower, the heat pump tries to act as an
on-demand device and a heat pump capacity issue arises"


But, using the T&P fitting to tap in, looks like a very easy fix..

Is the pic on this page: https://sites.google.com/site/altern.../Home/pictures
the R106H with the top off?? The parts list under the pic, makes be think I'm looking at a DIY project..

In any event, the guts look very interesting!

Tom is a mechanical engineer, and in addition to that, he had taken an HVAC course at a local community college. So I think he was publishing this info as a way to keep it all straight, and also to share what he was learning with other folks.

But regarding your comment about this looking like a DIY project, it looks pretty sanitary inside, but then this stuff really isn't rocket science.

The layout inside the box (in the pic) looks great.
But I didn't know if I was looking that the guts of his R106H or not.?.
That parts list had prices from Ebay..?. (Where I get a lot of my DIY parts)..

Anyways, I hope you are going to post a bunch of pictures of your new H2O Heater!
I'll keep an eye open for your new project thread.
We'll all be waiting for your evaluation of the R106H hardware and your
opinion about the difficulty of a DIY build of a similar unit..

I'm pretty sure it is the unit that was in his possession (and now mine).

I think he was trying to intimate that this could be a DIY.

OK, sure thing. Is there something in particular you want to know?

Sure thing. It is now the rainy season in Portland (my fair city) and it will be a while until I get serious about an install. I bought this wonder-machine because I knew I would kick myself if I let it get away... you just don't see this kind of unit coming up for sale that often... and it's already completely built... just connect the plumbing and plug it in!

"Is there something in particular you want to know?"..
Yeah.. The top view of the refer-to-water HX doesn't give much away about it's size.
A side view with a ruler in the pic would be nice.
That HX looks a bit like those two in the pics you posted the other day..
What do they call that a looped coil coaxial?

Self-Kicking fer sure!! That is one neat looking unit, like new! And the price you got was the whip cream on top..
Plus, it looks like he's already done some debugging mods.

~~~
I've been doing some self-kicking. A guy up the road was dumping a like-new central type AC ODU.
When I saw it, I stopped took a quick peek at the plate. Trane R410A @ 3 tons.
The owner told me it worked fine. They were buying a larger unit.
It was free! and it was gone when I got back from my medical appointment an hour later..

Should have canceled the appointment...

X her is a company which manufactures coaxial exchangers.Coaxial Heat Exchangers (1/3 to 20 Hp) on Doucette Industries, Inc.
I found a tube in tube they make FW2, list 780$, rated for a 2 hp unit just the other day for 100$.
Looking for a R22 heat pump now, madmodification to R-290, hope to make a Reverse Cycle Chiller like Reverse Cycle Chiller
Have been trying to find pictures of the inner guts of one of these things for a while, and still looking while I compile components. I think this FW2 is a great start thou.
Cheers all

I didn't recall how those RCC things worked.. But, I read this:
Heat Pumps For Cold Climates: Reverse Cycle Chillers | Heat Pumps - Detmer & Sons Home Comfort Blog

Which seems to say you just need to a larger ASHP that heats up a big water tank,
and then use the tank water to heat your home..

It seems like it's that large thermal mass of H2O that allows you to keep heating
when the temperatures get down under zero outside..
It's kinda like a GSHP, but without the ground..

Sounds pretty good, but what if it's really cold, for a really long time??

You are still going to need backup.. And, if you need backup anyways, why not just use a modern mini-split??

Heck with all this global warming & the Jet Stream staying up north,
the New England area is saving a bundle on heating this winter..
