The sacrificial anodes that come in the heater reacted with my water when it was heated, and produced hydrogen. I read burning hydrogen isn't visible, but the explosion certainly is.
Why is what comes out of the exhaust pipe the concern if it's just water vapor? What, coming out of the tailpipe, is gonna go boom? If it's just water vapor coming out of the tailpipe, how is it gonna explode?

I'm only more confused.
