Barndominium/Shop or "real" House?

[garc]

The way to go with hydronic heating is to use a heat pump as the source instead of a boiler. That way you can also have cooling in the summer (from the floors).
You have the potential for the most efficient system using in ground coils (ground to water vs. air to water) since you can dig to your hearts content!
Consult an expert, but I would thing you could have the heat pump switch between house and shop. Your shop will have a massive thermal mass which will heat or cool very slowly and hold it's temp for a long time. You dominium is the opposite and will respond quickly to changes in input to the floor. Warmboard could be the best flooring system to date! ...

The last part of the video deals with an air to water heat pump but you can do one better in ground with your excavator. The operational cost factor with heat pumps is roughly 25% of boilers.
The advantage of in ground heat exchange (below the frost line) is better performance in the extremely cold weather which you occasionally get.

I want central air of some kind. I need it quite cold to sleep. But without ductwork, not sure how that will work. I don't think cooling the floors with the radiant heat would work for me.

No, cooling the floors that way won't work.. especially upstairs.

I just assumed you would have an HVAC system to heat/cool the living area. With scissor trusses you could put the ductwork above the ceiling? If not it would have to be under the floor.

Another option is mini splits. Google search them if you aren't familiar.

I'm over 200 feet from my 50 meter pond (think Olympic pool) and the view is just right from my balcony

If I recall you're up on a hill? My lot is completely flat. I have parked my 575D and raised the FEL and climbed in it at about balcony height, and the view seems ok, but it's not jaw dropping etc.

Here are some pics of what the view would look like if I were standing on a stone patio right outside of the living room of my stick frame house design.

I had Warmboard in my ICF house design, it was one of the things that made the estimate explode. So now I'm thinking for the living space I would just go the more traditional route and put the tubing on the underside of the sub-floor with heat reflectors & insulation etc.

Please forgive me, I took some more liberties, LoL.

1: addressing OCD
2: easier access and reducing bruised hips
3: better fit ???
4: cross ventilation (fresh air when sleeping)

Those are all pretty good tweaks. I guess I don't really need all that extra countertop at the entry once I took away the old pantry.

I would have to think about the second window in the bedroom, would require moving and adding another post. I don't sleep with windows open, I sleep with AC cranked.

You are quite right about the hill; totally forgot! Your balcony puts you up nine feet and mine puts me at ground level for the other side of the house but there is probably another ten feet of slope beyond the garage below over the 200 feet so I guessing I'm roughly 20 feet above the pond level.

Regardless, you still have a lovely view especially if you trim the tall grass around the edge of the your pond

Most of it is, but I leave sections like that for wildlife purposes.

I like radiant floor heat the source of the heat could be any type of boiler or "hot" water heater. I am a
believer in backup heat sources so I'd go for two heating sources with the ability to valve either one to either
the garage or house or both. In NY I wouldn't go with an electric boiler but I consider most any other fuel.
The elevated balcony some distance from the pond may decrease the number of mosquitos.
I would also go with the mini-split for AC and supplemental heating some of the newer ones will be quite efficient even below zero.
Trying to cool the floor to cool the building will result in wet floors.

I would like to do geothermal someday. And if the ban on NG and LP goes thru, starting in 2030 we can no longer buy gas appliances. Stupid government... I still plan to put in NG anyways, as I have it on my street.
