I bought a house which uses a hydronic system for heat, with a Vaillant model no. GA92 080 at the heart of the system. I recently had to replace a leaking expansion tank. Though I had good advice from the person who sold me the replacement tank (which I was able to install), I became curious about more complete information on this unit and how to properly maintain it (I have always had central air until I moved into this place). In this age of information however, I am having the most difficult time locating any info about this unit. Any ideas?
Thanx
