We have recently designed the installation of a cast-iron sectional boiler an have experienced multiple crackings of the sections. The manufacturer of this boiler insisted that blend pumps be installed, despite the fact that the boiler has a three-way valve on the supply that diverts hot water to the return to maintain the return temperature during warm-up and part-load operation.
Blend pumps have been installed, and we have just experienced another crack, this time in one of the sections that had just been replaced. The contractor has observed that these sections are much lighter than those installed in the past. The controls contractor has observed similar problems in another instation of the same manufacturer's boiler.
Is anyone else having these types of issues? This seems like a manufacturing or assembly problem with the boiler, and the manufacturer is denying any liability. Any help would be appreciated.
