I decided to drain my Elektra Maxi boiler and have a look inside. It's hard to really inspect the inside of the boiler. Peering into one of the holes doesn't show too much. Umm, it's dark.

A few months ago, on a whim, I bought a WiFi endoscope. You can find these for about $35 on Amazon. Search for "Desptech wireless endoscope". Other than sticking it up my nose when I first received it, I've never used it.

Well, it works pretty well. See below stills from the video.

Flexible cable, several feet long. LED light on camera end. Easy to use. Cheap. Not waterproof as far as I know. But did I say cheap?

Anyway, I see gray stuff coating the wetted boiler surface. It's not shiny and coppery like it was after I restored it. Otherwise, not sure I know all that much more than I did before, but at least I know there's no sea monsters down there.

Should I fill the boiler with something active to deal with the gray stuff, or just drain and refill with fresh water every now and then?

Leave that copper oxide alone as it is what is protecting the copper.

I think you need more fiber in your diet. This is the worst looking colonoscopy I've ever seen.

I like using misc tools in the coffee arena also lol! We have a Klein Wifi Boroscope that is waterproof so I'll have to try that. I did take a pic of my Profitec Pro 600 with a thermal camera to see how it heats up. Cool stuff! Good thinking on the boroscope!

While you're in there check for mice.

I think I'll try a regular regime of draining and refilling the boiler every couple months. I have very soft water but there were still some gray particles in the boiler water. I'm already in the habit of drawing off a cup or two each day using the hot water tap.

The endoscope is also useful, it turns out, for inspecting the underside and hidden bits of the machine. And for looking closely at the group. And for examining your bald spot, gums and back teeth. Whatever did I do before I had this thing? They also have a model with a built in screen (don't need a smartphone to view image) that is not much more. I'll get that next time.
