The solution in most cases is to modify the boiler and/or feedwater system to prevent the sudden entry of cold water into hot boiler components. When a boiler is experiencing cracking due to subcooling and cold feedwater flow upon startup, one solution is to install an offline pump-assisted circulation system to reduce the thermal transients.
I will always preach that a successful cast iron water boiler installation begins with proper planning. I worked for an oil company for 20 long years, and 9 years of that I was a Service Manager.

Furnaces heat air and distribute the heated air through the house using ducts. Boilers heat water, and provide either hot water or steam for heating. Steam is distributed via pipes to steam radiators, and hot water can be distributed via baseboard radiators or radiant floor systems, or can heat air via a coil.
system for a stoker fired hot water boiler by a damper positioned half way along the length of the temperature in the outgoing hot water to indicate and control the load demand required
2013-10-9 · Hot Water Boiler • Boiler is filled up with water and maintains 12 PSI water pressure. • Air is bled out of the system zones. The circulator pump will not move water through the baseboard loops if air is in the system. • Expansion tank maintains system pressure, and absorbs water expansion and contraction from heating and cooling.
