Boiler Water Loops | HVAC Hydronic Piping Systems

However, only at the end of the loop because this part of the boiler water loop will have less heat. The radiators or baseboards at the beginning of the loop use most of the heat. Consequently, this is the reason for the larger radiators and baseboards at the end of the loop. There is also a larger temperature drop in this type of boiler …

The Steam and Condensate Loop | Spirax Sarco

Pressure reduction. As mentioned before, steam is usually generated at high pressure, and the pressure may have to be reduced at the point of use, either because of the pressure limitations of the plant, or the temperature limitations of the process. This is achieved using a pressure …
