Founders Building Hot Water system rennovation

Scope of Work Includes a turnkey project: • Removal of the existing electric tanked water heater • Installation of four (4) Navien NPE-240A2 tankless water heaters in the boiler room • Isolation of the commercial kitchen to continue operating on existing tankless units, ensuring uninterrupted service • Upgraded recirculation system: Removal of the external recirculation pump in the commercial kitchen • Use of internal recirculation pumps on both existing and new units • Integration of an external recirculation loop for the rest of the building • Insulation of all hot water piping, and insulation of cold water piping located in conditioned spaces • Use of a scissor lift and safe partitioning of work areas to maintain hallway access during construction Timeline & Impact: • Total project to work around class schedules with the least disruption • Hot water service will be temporarily interrupted for 1–2 days, minimized by assembling the new system in advance • All changes or updates to this timeline will be communicated promptly with facility staff and maintenance Permits & Warranty: Vendor will handle and provide for: • All permits • Coordination of inspections • Manufacturer warranty on the Navien tankless units includes: • 8 years on heat exchangers • 5 years on parts • 1 year on labor (with recirculation) System Redundancy & Reliability: The new system should offer built-in redundancy. If one unit goes offline for maintenance or service, the remaining three will automatically continue to provide hot water without noticeable interruption. This significantly reduces the risk of total system failure compared to a single tanked unit.
