I recently read a a question posted about lime build-up and a "boilout" on valliant boilers. I also have a vailliant boiler and have been trying to find information such as service manuals for my boiler. Where can I purchase this material? How can you tell if you have an excessive lime build-up and what is a boilout? thanks
