My Ideal Icos is 4yrs old and stopped working?

modern boilers are like modern marriages
[old boilers were built like tanks
virtually indestructible & ultra reliable]
you go thru the honeymoon period relatively trouble free
then reality bites within the first year
& cracks begin to appear in the relationship
after a few adulterous affairs along the way
the end is predictable & final
forget diamond & golden anniversaries
aim more for paper anniversaries
welcome to the world of modern high tech high efficiency boilers
