after loading my wood last night I failed to turn off my damper fan. Bout 630 this morning I woke to a boom. Man did I overheat. My pex finally gave out but it decided to break in the house rather than my outside boiler room. House filled with steam. Ran to the boiler and my water gauge indicator was well past the highest reading of 320. Of course all the sytem water was steam. I had to kill my water feed because my flat plate DHW had melted my regular water pipe, so then I couldn't put any cool water in the eko. So I shoveled out all the coals I could and let it sit with the pop off vave open. Its still bubbling, but down around 220 now. I don't see any metal damage to the eko, so I hope all will be Ok when it cools. Guess this is a good time to re-plumb my system! Don't leave your inducer fans run on thier own-hook them up to a sensor!
