Optimizing the Performance of Radiant Heating Systems

Jul 01, 2008 · The supply-water-temperature-reset control strategy illustrated in Figure 6 can be applied to primary or secondary heating loops. It goes a long way toward reducing energy consumption and cost. Supply-water-temperature reset also serves to better track building load, resulting in reduced boiler heat loss because of equipment cycling.

Explanation of Hot Water Heating Systems | Hunker

Hot water heating systems are built around the premise of radiant heat. Water is heated by a boiler and circulated throughout a building--usually homes (older homes, especially)--through a series of pipes that heat radiators that give off heat. The heat transfers to the air in the room.

What is the correct temp setting for a hot water boiler

The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency. Feed water preheating typically occurs in either the feedwater tank or deaerator using supplementary steam. Pre-heating the feedwater is the most basic method of mechanical deaeration, or the process of removing
