Underground Hydronic Piping
Description
- Projects in this scope area may include installing new underground piping for heating and/or drinking water supply and restoring grounds or asphalt paving. The full, detailed scope of work for this project including any additional work areas will be updated here after alignment with project stakeholders through scoping and design activities.
Baseline
- At developments where the existing heating system is hydronic, any new system should have the following features:
- Low water content boiler with sealed combustion air intake and flue
- VFDs on heating hot water (HHW) pumps
- Hydraulic coupler on HHW pipe system
- Indirect-fired DHW with storage
- Outdoor reset boiler control
