Absolutely, combis are the suckers bet. Indirect has some built in inefficiencies too because of losses across exchangers. An open system on the other hand, when done correctly, is superior to both. Most people don't know how to do an open system correctly though/are unjustifiably scared of it.

Yeah it seems open system have been in the realm of diy for a long time in our area. The problems aren’t a result of open systems themselves but of unqualified design and install. That’s given them a bad rap.
