DHW: Domestic Hot Water Only / POE: Point of Entry (100% incoming facility potable water) / Read more on DHW and POE:
Click HereFor DHW: A "Zone" is defined as the area where the technology will be installed. EX: When a DHW has multiple separate hot water makers, then this facility has more than one separate DHW zone. If the DHW Zones intermix, then there is only one (1) DHW Zone
Are any of the multiple DHW zones in a common mechanical room within 35 feet from each other? A separate DHW zone is defined by having it's own hot water maker that does not intermix with another one.
POE: A Point of entry "Zone" is defined as a main potable water line coming into a facility.

Application Guidance Result Recommendation
Based on your answers, you incoming water is below 20°C/68°F and you have a facility with a relatively low risk of water stagnation. As a result, you can focus on a DHW Only type of CSI application.
You can chose "DHW" from the Application drop down menu above.

Application Guidance Result Recommendation
Based on your answers, you incoming water is either above 20°C/68°F (OR) you have a facility with a relatively higher risk of water stagnation. As a result, you should focus on a Point of Entry (POE) type of CSI Solution.
You can chose "POE" from the Application drop down menu above.
Application Guidance
Is your incoming potable water Below or Above 20°C (68°F)
Where is the project geographical location?
Is there any chance of low occupancy that could cause water stagnation in areas of your facility? What is your facility average yearly expected occupancy rate? The lower your occupancy, the higher the risk of water stagnation and the higher the risk of Legionella growth within your facility potable water distribution network.
