Hi Tim, We're in our 4th year with an Eco110 boiler. Zero issues with the boiler on our old cast iron radiator system plus a Bock indirect. I was surprised by your post today stating the Eco will be discontinued. Any idea how long WM will provide support for the Eco with parts etc? I keep a maintenance kit and a spare circulator on hand as well as a fuel valve I found at a major suppliers close out. I found a good price on a replacement blower for the Eco and may pick it up as we intend to keep the house for a long time. I realize each installation and application is different but in general how have the earlier Eco boilers been holding up since their introduction in 2013 ? I check water quality, combustion gases and clean the condensate drain every year. I've opened and cleaned the HX every other year. Hoping to prove the modcon naysayers wrong and get 20 plus years out of it.
