I have a Dream 2

[Dads_FJ]

Thanks. I'm about caught up to where I am on the house. I have a few more things to post.

I'm about to switch out of working on the house every single day no matter what. To working on  some of the  fun stuff once in a while. Turbo bike  sled engine smart car. Might even  go ice riding on the Raptor.

All work and no play makes Dan a dull boy.  This one has really aged me. It's about to be worth it. You all are invited to come see my insanity in person.

"You all are invited to come see my insanity in person."

Sort of sounds like the makings of a central rally 

As you and I are well aware Wisconsin is a wonderful place to ride, here's a playground/loop I ran across which is a mere 80 miles hours away from Campbellsport:

Then there's https://www.roadamerica.com/ which is what, 1/2 hour away?  That would be an awesome place to hang out for a day (assuming there'll be races).  https://www.roadamerica.com/motoamerica-superbike-series

The EAA museum is just up the road too.

There are some good roads right around my  house it's part of the kettles.

Finally got the HVAC guy from work to come and fire up the geothermal and infloor system I installed. Took about 10 hours for it to  get caught up. Heating up the three slabs, 3 zones, 2400sqft downstairs and the 3 zones of warmboard, 1000sqft upstairs. Was out of the house for the last 4 or 5 hours. Holy crap house has freaking hot when I came back. 68° is way to high for the infloor heat.

[giantkiller]

Was -10f that morning. I'm sure the slabs got hotter than they should have before the ambient air temp. And over shot the heat. But 64f on the ambient is very comfortable with the infloor heat.

I'm currently doing a hydronic heated slab floor on a new house I'm building in Sedona.
I have 3 zones and each zone has a thermostat.
I have 2 choices for thermostat sensors,
1) an in slab, concrete embedded thermocouple or
2) an air temp. sensor

Which would you recommend Dan?

I know your question was directed to Dan. My 2 cents would be, thermocouples do go bad and having to replace one that is embedded in concrete would be a bigger headache then replacing an air sensor.

[giantkiller]

I have thermostats that have both. You can use the sensor for inslab or for outdoor temperature sensors. I put pex runs in the slabs. So I can put the sensors in later. Haven't gotten that far yet. I think for inslab house. That an outdoor sensor would be a good idea so you wouldn't have over heat events so much. But my 3 inslab zones are in the shop and storage downstairs so temperature swing won't be noticed. The 3  zones upstairs in living Area are warmboard. Warmboard in my opinion after studying everything that was out there. Is the most efficient and fastest response available. So  really doesn't need infloor or  outside temperature sensors. Like a slab.
Wow Pat looks like way more than 3 zones.

I used 3/4" barrier pex inslab. So the sensor can be easily pushed down the pex runs with a wire fish.

I obsessively studied every aspect of this house before, during, and even a little bit after

Thanks Paul, I was thinking the exact same thing....I'm going to embed 2 thermocouples per zone...that way, if one goes bad, I have a back up.....and yes, per your suggestion, I'm going to bench test each thermocouple before I use them.

Ok, thanks Dan, I will look into that option....a thermostat that can use both sensor types...that's the answer.

Wow Pat looks like way more than 3 zones.

There are 9 circuits total, left zone has 3 circuits, center zone has 4 and the right zone has 2 circuits.

Thanks guys, appreciated, very helpful....now let's return back to Dan's pad...

So I've had the geothermal heat pump  running for 3 going on 4 weeks now. It's been great having warm floors under my bare feet when it's in the  negative temperature's outside. That  first day I was gone while the house got up to temperature.  First thing I did when I got home was take my shoes and socks off. And go stand in the shower so I could feel the warm tiles of the shower floor. Woohoo!!

[FJmonkey]

After all that effort Dan, you deserve to enjoy it.

[Pat Conlon]

 +1 on what Mark said....

[Waiex191]

That is awesome.  My old EAA hangar in Elmira NY had a heated floor and I loved that system.  It was gas vs geothermal, but having a warm floor is definitely cool.  I mean warm.

[Troyskie]

Nice one Dan!

I like your thermostat solution. During install it is waaaay easier to add some redundancy than to try and 'work around' later.

Last year we heated our bathroom floors. Super simple compared to both your and Pats jobs. The only problem I had was stopping the kids from changing the setting to 'Surface of the Sun'.

When you made the comment of shoes & socks off, aaaah, super nice.

Thanks guys. It's been a long haul.
My Bosch geo unit has the optional heat recovery package.  It makes your domestic hot water. Free.
The  compressor for the  heat pump in the unit makes lots of heat.  Whether it's making heat for  infloor heat in the  winter. Or making cold water for the chilled water fan coils in the summer(AC).
So for the HRP they put a water jacket around the compressor. (Makes your hot water, and cools the compressor making it last longer) To take that heat and put it in the domestic hot water by circulating it through the jacket around the compressor.  Well the water in Campbellsport.  I've been told will kill a water heater in 3 or 4 years. The geo unit costs over $7000. They make storage tanks with heat exchangers in them to keep them separate. But they are expensive too $1200ish. So I had to engineer a way around that. This is my solution.
