My Feroli condesing boiler is losing pressure. I have had to top it up for a long time but whenever we called somebody out to see it, because we have underfloor heating, presume its the pipes buried under the floor.
My husband is a piping engineer and we have checked them.
We have heard of other condensing boilers getting blocked
Any ideas as we are sure it is the boiler given that it has had small leaks.
