Hi
I am planning to install unvented indirect cylinder. ATM I have gravity system, cold water tank feeding HWC and F&E tank for central heating in the loft. The mains water coming into the house is with 15mm copper pipe, pressure 4 bar
I understand I need expansion vessel for the unvented cylinder to get main pressure hot water of max 3 bar. I want to know whether I can keep the F&E in the loft meaning keeping the central heating on gravity as it is at present?
TIA
