One for the plumbers - in the process of fitting a Nest I found that our (unvented) hot water tank thermostat is busted and doesn't shut off. It's a Range TS207 dual stat, seems to cost about £45 upwards. I came across this for £25:

Need to check that it fits the same pocket on the tank but looks like I could keep the tank at 50C instead of 60C and save some gas (see the info about the weekly overheating). Anyone know anything about these?
