I'm curious as to how you are getting around installing a non ASME rated pressurized boiler here in Michigan? If there is a "loophole" around the code I would love to hear it. As you know, it is illegal to install a non ASME rated boiler for use in a pressurized system here and that can raise a lot of problems with insurance if an "incident" occurs. Just askin........
Not true, Heaterman. Direct from the state of Michigan boiler code:
R 408.4047 Exempt boilers....
Rule 47. These rules do not apply to any of the following:
...
(h) A water tube or coil type hot water heating boiler requiring forced circulation not
exceeding any 1 of the following:
(i) Maximum water temperature of 200 degrees Fahrenheit.
(ii) Relief valve set pressure of 30 psi.
(iii) Heat input of 200,000 BTU/hr.
I did a fair amount of reading before going forward with my EKO. There are pleny of non-ASME stamped boilers in operation in Michigan, legally, operating at 30psi or less.

Define "water tube" boiler? The EKO uses HX tubes to transfer heat to water. I guess I don't know exactly what definition the state of Michigan proper intended here but since the words are not capitalized it leaves a bit up to interpretation. And as stated above...EKO's are being inspected and are passing in Michigan.
