Pumps UK were contacted by a company that specialise in energy saving recently, and we were asked to carry out a life cycle survey on all the heating pumps for a building at Royal Arsenal.
They currently had four twin head circulators that were all providing heating services for four separate blocks of apartments. The existing pumps had been over sized and were running at 100% of their capacity. We carried out a flow test on each pump set and found that we could reduce the size of pumps and achieve the same flow rates required for the system.
We decided to install Lowara e-LNTH pumps with 5th Generation Hydrovar variable speed inverters. We removed all four pumps and installed the replacements in the same position. The new pumps were smaller, so we had to modify the pipework using Xpress carbon steel fittings.
All four pumps were installed over two weeks with only two days of shut down time on the heating system. We planned the work so the customers clients were informed well in advance and everyone was kept happy during the project.
