@mhkohne nah, if the fridge's heat quits going into my oven then it'll just take as long to prewarm as it already does.
Machines can be made so that if one part stops working, it puts a note in the log and carries on going but a bit shittier. Most machines IRL work like that, except for the crap ones of course
@ifixcoinops Ahh, but then you've further increased the complexity, leading to greater likelyhood of failure.
What we actually need is a fairly simple way to store and release heat the way we do with batteries for electric. Then you can just equip any heat-wasting devices with an output to the 'heatsink' and any heat-using devices to take heat FROM the heat-sink, with everything capable of also operating without a house-wide heat sink.
