hi
i am installing evac tubes BUT system had 40 hp tubes with 8 litre expansion vessel supplied and i got another 30 tube panel to add to system. it is piped in 22mm copper (about 23m of pipe) i am running it through my existing coil (was on oil burner) of a 250 ltr copper insulated tank and i am going to heat dump via solar coil into 1000ltr buffer tank.
so to my question would an 18ltr expansion vessel be good enough for a 70 tube system as i have one to hand and how do you work out the sizeing of the vessel.
thanks
