With non electric zone valves on each radiator
One disadvantage of using a one pipe heating system is that what?
For heating and cooling, one pipe is a supply line and one is a return line.
Water is "lazy". It runs from high pressure to low pressure and always takes the path of least resistence. In order to balance the heating and distribution system so that all heating appliances in a modular hydronic system do the same amount of work, you must pipe the returns and the supplies in such a way that "in" flow of water into the heating appliances is equal to the "out" flow into the system.
So the pressure wont bust the pipe.
It is the THINNEST ply of copper pipe and is ONLY used for heating purposes like baseboard heating!
Not sure what you're asking. Do you need to know size of piping or what kind of pipe to use?
normally back to header tank but in some systems where there is no tank there will be a small pipe going through wall to the outside of the property
yes, but you will probably have to customize the pipe setup a bit, and probably upgrade the pump.
Bleed it /Purge
It is very easy to damage any copper pipe.
Yes, copper piping is usually recommended for both hot and cold water systems.
Bleed the accumulated air out of the system. I did it twice a year, to improve heating efficiency, and eliminate banging noises.
