I have just moved into a flat with a wall mounted Vaillant TURBOmax VUW GB 282/2-5 boiler (also says TURBOmax Plus 828 E on the serial number label, not sure which name I should be using!).
The pressure gauge is at 0 bar so I need to know how to top the boiler up.
Can anyone help me figure out how to fill it up? (I've tried ringing the support number on the boiler but to no avail!)
