"That Truma Combi looks like a pretty sweet "holy grail" all-in-one furnace/water heater.
....but....am I missing something? Is there some reason why you would not to be able to safely actually drink any of the water that the Truma Combi heated up? (Apart from the obvious "wait until it cools down enough to safely drink...." )
Just spent some time going through the technical notes on the manufacturer's website, and came across this bizarre-sounding statement on a page that dealt with routine decalcification of the boiler:
"Do not use the water from the Truma Combi as drinking water."
No making hot tea or ramen noodles? I would hope these aren't meant to only safely heat water for showers and washing dishes.....
