So, first no-hot-water-pressure morning of the year. Plenty of hot water - just not getting to the shower head.
Cue getting the ladder out of the garage (it didn't seem too cold outside, probably because all the moisture had frozen out of the air overnight) and scrambling around in the ceiling. Managed to confirm that water was still flowing into the header tank just fine (and even if it wasn't, the tank is hardly a sealed system so should still have been providing pressure), and all the pipe I could find was still wrapped in insulation. It almost looks as though the weak point might actually be where the polyeth pipe passes through the top of the cylinder cupboard, if the problem is indeed ice in the pipe to the cylinder.
Have formulated an alternative theory that perhaps the lack of pressure stems from a lack of cold water to the mixer rather than hot. By the time I got out of the ceiling though, pressure was returning (and of course I was running late) so further experimentation was suspended
Also considering turning on the extractor fan in the kitchen on particularly cold nights in the future to blow more warm air into the ceiling (recall this problem only started after the insulation was put in last year).

So, car. Service center rang a little while ago. They think the problem was that something in the multiplexing had itself in a metaphorical knot and wasn't sending a correct or strong enough signal along the wire. They still don't know what the problem was (diagnostics saw all the right signals) but they've unplugged everything and plugged everything back in in the process of testing and now it works.
However, unplugging and plugging everything in a Prius takes a lot of time and dismantling/reassembly. They've decided to only charge for 7 of the 11 hours, for which I'm grateful.
Modern cars - cheap to run, expensive to break.

I'm not even going to start on what happened at work this morning. Yay breakdowns in communication :(
