Hi all,

Back with an update. The water heater is installed, after a long and difficult series of unfortunate events (see my second to last blog post), and the Raspberry Pi controller is now happily measuring temperatures and switching the pump.

Adventures in home improvement: Controller and manifold

The whole wiring job was really easy (of course I've got to do a little bit of cleanup and water proofing to make sure nothing ever goes wrong), and once the controller was hooked up to the sensors and the pump via a relay, everything worked on the first try.

I'm currently tweaking the water temperature and flow rate to see how that affects heat output, as it's not nearly as much as I'd hoped (although enough to keep the house comfortable). I hope to have some time tonight to push the source code for the controller software to github.
