Bonjour Dave,
Having a too large boiler for my boats, I have transformed it as my "workshop" boiler. you are right, difficult to have only one connection with different machines, so I make a brass or copper adaptator for each test just after the oiler, example :
For this last test, I tried thick silicone pipes... Unsuccessfully because of the heat and the pressure which soften them
If someone knows a really armoured silicone pope, I am also interested !
