Hi, Scherif
you could always dispense with the header tank and fit an autoclave (bladder), these are sized according to the system internal volume and operating temperature range.
Failing that I can add a link to the Grasso site where they have a very good description of a hydronics system.
Regards. Andy.

Re: design of expansion tank
i need some expansion calculation.
1) System total hot water volume = 1,300 cu. meters (Including pipeliens & boilers)
2) Boiler Design Pressure = 200 psig
3) System Pressure = 10 bars (145 psig)
4) Water Inlet to Boiler = 140 deg. C
5) Water Outlet from Boiler = 155 deg. C
how much will be tha expansion
