    I am looking at a 5-year old Eko-40, which I am planning to buy from a local individual. Any advice or opinions on what to watch out for?

    I used to operate an EKO40 and would ask the following questions:

    1.) Was the boiler used with a loading valve arrangement?
    2.) Was the boiler used with storage?
    3.) Why are they selling the boiler?
    4.) Have any components on the boiler been replaced?

    Just out of curiosity, how much are looking at pay for the boiler?

    Thanks for responding. He did provide low temp protection but with circs, not with a mixing valve, and I don't think he got around to adding storage. I don't know if there would be a way to inspect for signs of thermal shock. He is a logger, and wants to burn green slasher ends he gets for free without processing them. He said the target refractory in the secondary burn chamber was replaced early on in the life of the boiler. He wants $1,700 and he will load it onto my pickup truck. Seemed fair to me, but I am new to this. I currently use a perfectly good Buderus boiler that is simply too small for my house.

    $1700? And you are asking us about it? That seems too good to be true.

    If you are really worried, I'd bring the proper plugs and do a quick pressure test.

    Look over the bottom of the fire box where the nozzle is formed.
    The nozzle opening should be fairly uniform but might show some rounding of the edges.It's cast in place so not easily replaceable,although Myself and others here have had success with firebrick overlays or patching with refractory cement.

    Also check the controller and fan for proper operation.

    Other than that they are built like a tank.

    Good idea. I should have thought of that.
