1.3.4 Maintenance and inspection of DHW pumps

Description

The water needs to be boosted by electric pumps to get to the different end points of consumption of a building. The resulting electric consumption can become an important part, especially in high buildings; therefore it is necessary for the installation to be dimensioned correctly. It is recommended to perform a correct maintenance and cleaning of the water pumps on a regular basis to avoid unnecessary energy consumption.

Benefits

  • The saving potential is low; it depends on the water consumption of the building. Savings of up to 30% of the electric consumption of the pumps can be obtained

Limitations

  • Operation and Maintenance (O&M) staff size, skill level, and budget need to be considered

  • Just applicable for buildings with centralized HVAC system

Economic assessment

Initial investment: zero-low. It is one of the measures of maintenance, which in general do not have associated costs.
