and the more built-in and capital intensive, the worse it will be. It's not so bad to have an internet radio die, as has happened with several architectures thus far, but it's painful when there's real money involved. I always marvel at the people who built new homes with subfloor heating systems who usually have a closet full of manifolds, valves, custom PCBs-in-a-box, none of which will be available in a decade or two. In addition, even if well supported (like Tesla), there's a number of product families that are priced like long term investments (electric cars, solar panel/battery setups) but have shorter term PC-style turnovers in technology. They may still work, but will be obsolete.

Subfloor heating systems aren’t just a water boiler in the basement and bunch of dumb water tubes?

  Yeah I don't think the person you're replying to has any experience in building control systems. I used to be an energy engineer and I would predict sub-floor heating owners will have no real issues here.

    The point does stand generally though. I have had to replace entire HVACs because the coolant is no longer available or because the cost to replace a certain component is too high because the parts are no longer readily available. I think the only solution is to try to build as minimally as possible. A huge amount can be accomplished through passive heating and cooling (windows placement and size, site location and angle toward prevailing winds and morning / afternoon sun, etc etc). We are too often reliant on technology to allow us to ignore these things and we do so at our peril.

    >experience in building control systems lol. If you mean 'design', you'd be surprised. Admittedly, I'm not aware of the full array of residential heating control systems, but I've sure seen some over-complex ones.

  I've seen some that most definitely were not, usually along with a bunch of other high-efficiency tech. To be fair, I've seen minimum systems also, so it can be done. My general take on home design is simple-passive-accessible. Someone in the future will thank you. It's worth poking around manufacturer's websites. http://www.pexheat.com/Catalog/Controls http://www.pexheat.com/Catalog/Controls and consider the lifespan of a house vs. the lifespan of the subsystems. My general take is that the more built-in and difficult to modify it is, the madder someone will be in 50 years. In the interest of full disclosure, I'm no fan of radiant heating systems having seen the issues of parts availability, latency, the tearing up of floors for repair,and a strong preference for point sources of heat (gas stoves for example), so it might show through in the comment.

Recommend reading "Ghost Fleet" where even your toilet stops working when we go to war with a country that manufactures many of our electronic components. When you get bored, list all of your connected home and personal items that rely on wired, cable, wifi, bluetooth, rfid, infrared, cellular, etc. Put them in a spreadsheet. Then you will not be as surprised when your lighting system, refrigerator, or washer/dryer is hit with ransomware.
