And Congratulation's on building your RMH!
The numbers and temperatures you are getting are right where they should be for a new build.
Currently with no mass .
You are shedding heat from your pipes until you create a heat holding mass over top of them.
Once you add your extra pipe run and cover it over, your stove will burn even better.
No worries that your outlet temp will be low.
Good Job ! We would like to see pictures.
