I don't know any lineages that teach tsa lung in Germany, though I vaguely remember a Gelug teacher who I think visits Germany. I'll check.
There are quite a few tsa lung teachers in the US. The Palyul lineage teaches it at their summer retreats, though you have to do their ngondro retreat first or finish ngondro in some Nyingma lineage. See
http://retreat.palyul.org/node/5 . This system does include tummo (though not all tsa lung systems do). Namkhai Norbu's students and Tenzin Wangyal's students also teach different tsa lung systems. Tenzin Wangyal's site is ligmincha.org , though I don't see it mentioned there. You'll see it listed as "trulkhor" which is the word for exercise. They used to teach it in short (I think 4 or 5 day) retreats twice a year in four parts. All three of these are taught in the context of dzogchen courses.
