hi there, ill make this as simple as possible!
remaha avanta 18s boiler, commissioned in August 2010.
lost pressure, bar went to 0. topped up, worked fine for a few days, lost pressure, etc.
replaced pressure relief valve and expansion vessel (8 litres). we have around 12 rads and 3 towel rails.
problem still occurring. no idea what to do apart from refill it every few days!
edit: it has been fine from 2010 to 2014, and happened once in nov 2014 and a few times now this year.
