Series 24 Minimum Piping Recommendations – Water Boiler

Impact of System Piping Many hot water systems

are zoned. Some also use mixing valves to control the water temperature in the system. These features can cause the flow through the boiler to vary dramatically, depending on the status of the zones or mixing valves. In addition, the large water content of many commercial systems has the potential to subject the boiler to operation with low return temperatures for an extended period of time. These factors can shorten the life of a boiler due to thermal shock or flue gas condensation.

Crown’s 3 Recommendations On the following

pages, CROWN provides three basic recommendations for near-boiler piping that are intended to maximize the life expectancy of the boiler by protecting it from flue gas condensation and thermal shock. Each protects the boiler by making sure that both of the following conditions are met:

The flow through the boiler is high enough to ensure a temperature rise of less than 40°F

The return temperature does not fall below 135°F for an extended period of time.

RTC Return Temperature Control Piping

Recommendation 3 makes use of CROWN’s optional

RTC (Return Temperature Control). This control provides an economical and effective way of protecting the boiler from thermal shock and condensation. It can be incorporated into most hot water systems with minimal modifications to the system design and operation. When this option is used on multiple Series 24s, one RTC is required for each boiler. The CROWN RTC is also available with an outdoor reset option. This provides additional energy savings by modulating system water temperature to match the building load requirements.
