The main purpose of an Energy Check is to provide an overview of the energy saving potential of the installed pumps. The check is based on pump data as provided on the nameplate (Q, H, and P2), pump age, and operating hours. Known factors that impact energy consumption. Life cycle cost (LCC) analysis is useful when the pump owner wants to analyze the LCC of the selected pump, choose a new pump solution, or estimate whether or not it would be profitable to replace an old pump system... and support and document the decision with hard facts. The Energy Check Tool App is used for collection and upload of data. No calculations of energy savings potential are done inside the App. Please note that you need to acquire a specific approval from your local Grundfos company before uploading Energy Check data to Grundfos.
