Leakage on Combi Boiler

[GRBASF]

My GasCentra Heating System - Vokera Compact 29 Combi Boiler is requiring topping up every couple of days due to the bar temp.guage falling to near zero, it should be 1.5 to 2 bars. A Plumber has installed a sealant liquid over a week ago. There is no obvious leaks with water coming through floor boards etc., Any ideas - it must be in the system somewhere?

Help!!

pressure relief valve/pipe outside leaking?

heat exchanger leaking into condensate pipe?

Does it loose pressure if you put the pressure to 2 bar and then not
use the hot water or central heating?

Just had engineer out, checked boiler. All OK. As soon as he turned on the "service" valve the pressure dropped, he assures me I have a problem within the system. We top up the system every other day, where's the water going? No puddles, no leaking ceilings! it's a mystery! My plumbers coming back tomorrow morning ( about the third time now!) I'll keep you posted. Hopefully we'll get to the bottom of it.
