Steam boilers from Bosch - highly efficient and reliable

Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW)

How to Set Hot Water or Steam Heating System Pressure

Dec 30, 2019 · Pressure changes of a few psi one way or the other can be brought about by atmospheric conditions. Most boilers are safe up to around 30 psi, at which point seals can begin to fail. Modern boilers aren't nearly as dangerous as early steam engines, but you can still damage them and require costly repairs. Provided your boiler stays in the 12-30 psi range, you're in no real danger.
