Re-filling a pressurised system

[wotan]

Is it possible to re-fill the system from the bottom most point i.e.. drain valve on bathroom radiator, the reason I ask is the boiler is located in the loft space of my bungalow, and due to poor health and lack of confidence I find it increasingly difficult to climb into the loft.
I have considered extending the filling loop downwards (valve and pressure gauge) which could then be accessed via step ladder in built in wardrobe, thoughts please.

You can if it easier, you just need to keep a check on the pressure gauge and bleed air around the system as normal.

I'm sorry to hear of your plight!
If possible, it would be better to get a plumber to relocate the filling loop and gauge to somewhere more accessible for you and, if you are getting regular pressure drops, to investigate and remedy the fault.
All the best,
