Valliant Boiler

Hi
Got a strange problem with my boiler, I turned the heating on last night and realised the radiators wernt getting warm, and had to top up the boiler
I had a shower this morning, came home from work and it sounded like the boiler had been on all day. I turned the heating on, and the pressure dropped, but it seemed to struggle to get past 50 degrees. After fifteen minutes or so it had hit 70 degrees like normal.
Any ideas?!

When things cool down again the boiler needs topping up to replace that dumped water.
It's a small copper pipe that is usually bent to point back towards the wall, although older ones may just point down.
It only had a new expansion vessel fitted in November 22
IM not sure (but hoping!) that comfort mode has been running since then - I spotted the "C" on the display this morning and turned it off - see how that works out now
He tried recharging it last time which worked for a week, but then he had to replace it a week later as i had the same problem (pressure constantly dropping)
They are not too expensive and you'll find them with an online search.
There are some helpful knowledgeable posters there, not that the answers here haven't been helpful. I am not sure that expansion vessels are filled with nitrogen.
