30he

The HeS 30 (HeS - Heinkel Strahltriebwerke) was an early jet engine, originally designed by Adolf Müller at Junkers, but eventually built and tested at Heinkel. It was possibly the best of the "Class I" engines, a class that included the more famous BMW 003 and Junkers Jumo 004. As it started somewhat later than these two designs, and was thus expected to enter service later, the Reichluftfahrtministerium (RLM) ordered Heinkel to stop work on the design and put their efforts into more advanced designs.
The HeS 30 was designed before the RLM introduced standardized naming for their engine projects. It was assigned the official name 109-006, and it was sometimes called the HeS 006 as a short form. Development ended just as these names were being introduced, so "HeS 30" naming is much more common.

    Main 30HE - Heat leaking to CH when running DHW

    I have a Main 30HE with the problem that when you run the DHW, the CH flow pipe gets hot. Not all the heat is passing down there as the DHW does get hot, but this is going to cause some efficiency problems as radiators are getting hot if you run a tap for long enough, and it is probably going to...
