Electrically heated tap/faucet teardown.

Made me chuckle, forgot all about that 😊

Thanks for the laser cut and etched wooden tray.

Clive, I think it's worth hooking up and simulating the failure mode by shoving a dolls head over the spigot? 🤔

I'm not sure how well that would work. I have got some replacement 120C thermal fuses though.

Big Clive

Could you maybe reset the thermal fuse by reheating it upside down? Or did the extra yellow goop in there also reflow under heat, ensuring that you can't?

That's a good point. I hadn't considered that it is effectively acting as a flow switch due to the pressure differential.

Big Clive

Better quality than expected and full of crunchy goodness :). Looking for ward to the shower teardown, my life has been blighted by these useless devices with their pathetic dribbles on many occasions. Feel free to explode/crush/immolate said device in any way you feel fit.

I suspect that blocking the outlet wont cause overheating. Reason - There would be equal pressure on each side of diaphragm. Explanation - The back of the diaphragm appears to be exposed to the pressure directly from the ceramic tap output. The other side of the diaphragm appears to be exposed to the pressure in the heating chamber which is fed through a restricting port from the ceramic tap output. If there is no water-flow there will be no pressure difference across the restricting port / diaphragm, hence no power to heater.

I've never worked at Glastonbury. It sounds like an electrical nightmare with the amount of rain and mud they usually experience.

Big Clive

Are you working Glastonbury this season? There's a great field test item this year. <a href="http://www.bioenergy-news.com/display_news/12484/pee_power_to_provide_bioenergy_at_glastonbury_festival/" rel="nofollow noopener" target="_blank">http://www.bioenergy-news.com/display_news/12484/pee_power_to_provide_bioenergy_at_glastonbury_festival/</a>

It appears very well made. Good quality electrical connections, multiple safeties, etc.
