The purpose of the question is to guide you to thinking of the boiling point of water at different pressures other than atmospheric. As the steam pressure is limited by the pressure the relief valve permits the system to reach, and most residential boilers have relief valves of 15 psig, the temperature at 15 psig for steam is your answer. As most residential hot water boilers have 30 psig relief valves, the maximum temperature will be reached when the valve opens. I'll let you search on Google for the steam tables to let you find the temperatures according to the pressures. There is more value in reading and understanding the steam tables than there is to get a flat answer. As residential steam boilers are built to operate around 1 psig, you might also look up that temperature as well, because that is what the radiators will reach to provide output, which is important to know to properly size radiators.
