Boiler Project Fundamentals – AIChE

solved solids do not accumulate in the boiler of a hot-water system, so there is no need for blowdown. Although some manufacturers use a similar design for their steam boilers and hot-water boilers, hot-water boil-ers are typically more efficient than steam boilers. Because steam boilers require much more heat to create steam, there

Hydronics – Step By Step – TACO

Pickup allows for the heating up of cold cast-iron boiler sections and cold steel pipe. Both need to heat up before heat can be delivered to radiators. Newer mod-con boilers usually have only a DOE rating and have no pickup allowance since they are very low mass and heat up relatively quickly compared to a cast iron boiler.
