I have the EKO 40 Super which is in its 4th year of use, the condition of the boiler is excellent. Would anyone be able to give me an idea what I could sell this system for including all the controls, expansion tank, pump, etc.
Thanks
Thanks

If the S&R temps are only seeing a couple degrees Delta T then the pump could be way oversized. To maximize efficiency a Delta T of 20 degrees should be maintained , if not , there isn't enough BTU's transferring to the radiation. Simply by slowing the pump down you will see a higher DT. Just because you have a low temp loss over a run doesn't always mean its efficient.
