Historical Design of Hydronic Systems • Primary/secondary loop with non-condensing boilers – 180°F hydronic loop setpoints – High return temperature needed to protect boiler from condensing and corrosion – Primary/secondary pumping – Calculate "design day" load, select one large boiler, put in a second boiler for redundancy 3

Hurst Boiler has been manufacturing, designing, engineering and servicing gas, oil, coal, solid waste, wood, biomass and hybrid fuel fired steam and hot water boilers since 1967. With installations across all industries worldwide, Hurst Boiler is recognized for the highest code standards, innovative engineering and
Read MoreThe basics. The hot water boiler does not boil water. It warms the water up to a maximum of 220 degreesF 104.4C. If you are wondering why the water does not boil, it is under pressure. The pressure increases the boiling temperature of the water. The water is then pumped throughout the structure to terminal units (radiators, baseboards, even the

Hot water or steam boilers are relatively similar in design (Figure). The boiler pressure vessel is a horizontal, cylindrical tube closed at both sides with an end plate and insulated all around.

Read MorePickup 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.
