Worcester greenstar 4000 refill system

Hi guys just wondering how to top up pressure on this Worcester boiler after draining system down
Also an unvented cylinder upstairs and solar panels
Many thanks

The filling loop is likely to be located in vicinity of the unvented cylinder.

Hi Chris I did initially check there but could see any filling loop , the pressure gauge is here I will attach a pic

once loop connected, open the 2 black handles, raise to suitable pressure (approx 1.5 bar) and turn off black handles, remove loop and replace caps.

Yeah, I would turn it off to prevent unnecessary firing/dry fire situation. Just out of interest, what work are you carrying out?
