The boiler is piped to indirect coil cylinder , sealed system " cant see feed & expansion header tank" , cannot see a pressure gauge for heating circuit. ( Hot-water cylinder is fed from cold storage in loft.) cannot find a filling point on the return side of hot water cylinder or return on heat emitters?
Could someone who is maybe familiar with this old boiler give some advise thanks
