  The hoses are 7/8th EPDM type, or 22MM ID.  The Alde uses the "non reinforced" type hoses, but I didn't look for it very hard.  I used the "2 ply" from here last year.

  Alde used to have a web page that was sort of a pain to use, but, it was usable. Now....it has been labeled "Truma" and updated and it is a complete disaster to navigate.

  Here is another discussion on the hose sizes in an early stage of the Alde deconstruction for the glycol change.

  Replaced my Rhomar glycol today along with some other changes to the heating system. If anyone finds this thread looking for tubing specs, I purchased the same product that @pthomas745 linked to above. Because of the reinforcement, it has a slightly larger outside diameter. The spring band hose clamps fit, but they were just a little more difficult to get over.
  
  Picture for comparison ...

  @AnOldUR If you haven't replaced it yet, I ordered mine directly from Truma customer service parts along with new parts including new convectors. They were very helpful in ordering the parts. Here's the address from my receipt. The tubing was $12 per meter. They cut whatever length you need and then you can cut to each hose size.
