Natural History Museum Upgrade To PLATEflow Performance


When it came to upgrading the existing calorifier at the Natural History Museum in London, the expertise of the technical team at McDonald Water Storage came to the fore, helping to specify a PLATEflow commercial cylinder to provide the perfect solution.


Protech Heating were tasked by CBRE to provide a modern, more efficient solution to replace the existing aged calorifier and reduce the required water storage at the same time.  Following discussions between Henderson Warnock and Protech, McDonald Water Storage were contacted to specify and provide one of our PLATEflow solutions.


Protech was tasked with the replacement of the existing calorifier within the Natural History Museum London, and approached McDonald Water Storage to provide a solution to ensure they achieved their remit of a more efficient hot water delivery throughout the building, whilst vastly reducing the required water storage within the calorifier.

Henderson Warnock liaised with David Stewart at our head office, with all the relevant information on the existing calorifier,  to determine what PLATEflow unit would be the suitable replacement. The unique design of the PLATEflow unit selected allowed a reduction of water storage capacity of circa 50%, whilst achieving a quicker and more efficient hot water delivery throughout the site.

The cost effective solution, a 1,100 litre unvented PLATEflow unit, was found quickly and presented to the client and signed off. Due to the easy installation of the PLATEflow units, the changeover went quickly and smoothly and from switch on to delivery of hot water at outlets, the McDonald unit reduced the heat up time dramatically and fulfilled every promise Protech Heating made to their client. Effectively working in such a prestigious building and carrying out a hot water changeover that serves laboratories within the museum, the performance of the McDonald unit was the one thing that Ian at Protech didn’t have to worry about.


Ian McKinnon of Protech

‘The reason the McDonald unit was specified is quite simple, Protech do not use any other supplier for this type of equipment due to the reliability and quality of the units supplied. Currently we have fitted these types of McDonald units within buildings such as schools and sports centres, where the delivery and availability of hot water is crucial to the building remaining open, and to date have never seen a closure due to non-performance of a McDonald calorifier.’

Craig Stalker, project manager at CBRE

‘I had the joy of working with Protech at the National History Museum for the first time during this project and I was extremely impressed. From day one they were quick, efficient, highly professional, and delivered the project on time as per the programme.

“Protech came armed with extremely competent engineers and a positive can do attitude, which enabled the installation of the PLATEflow cylinder to run smoothly and with minimal disruption. If a problem arose, they rest assured they would find the solution to ensure that the project is not compromised. I would highly recommend McDonald Water Storage and Protech for any and all mechanical projects without fail”.
