Located on the roof of the three-storey building, the new Elco heat pump is providing space heating to the main office areas on the second and third floors, as well as stairwells and washrooms. To accommodate the lower flow temperatures of the Aerotop unit, the refurbishment also included the upgrade of heat emitters to Type 33 radiators. The system is now delivering highly efficient heating, and is part of the Lloyds Banking Group’s desire to remove inefficient systems from its property portfolio and be carbon neutral by 2030.

The M&E consultants for the project were Mitie, with the Elco Aerotop heat pump specified by project manager Steve Bell. Commenting on Elco , Mr Bell said: “We have previously fitted Elco boilers on many jobs in the past, but this was the first time we had used their heat pumps – and we’ve been really impressed. We were recommended the AEROTOP unit by Alan Hough, the local sales manager, and after comparing the specification and performance against our usual supplier, it made complete sense to use it on this project. It’s now up and running and operating perfectly.”

The heat pump was craned into position on the rooftop and connected to the existing heating system. Plus, thanks to the built-in protocols of the Aerotop unit, it was easily synchronised to the BMS to allow centralised control of the heat pump’s operation.

The Aerotop M reversible heat pumps are available in outputs from 24kW to 48kW, and all models supplied with flow and return manifolds for arrangements of up to four heat pumps, while 16 units can be managed by a cascade controller. The Aerotop range also extends to ‘L’ models which can deliver outputs from 54kW to 88kW.
