Crane Hot Water Heating System

Hello again, our house which I mentioned in another post has hot water radiant heat with pipes in the attic, and in under the concrete slab foundation. I found some information that the system put in was made by Crane. Also, the boiler was originally a Crane oil fired boiler, but was replaced 25 years ago with a Weil-Mclain Gas fired boiler. Could someone tell me the quality of the Crane system, or has anyone worked on a Crane Radiant Heat System.
