Demand for CUBEflow Grows
McDonald Engineers has seen a sharp rise in the demand for its CUBEflow range following the announcement that Elson will stop production of rectangular hot water tanks at the end of this month.
McDonald Engineers has a long standing reputation as a manufacturer of rectangular hot water tanks however, the company had been manufacturing them as a bespoke item as opposed to offering a standard range.
However, with the launch of its CUBEflow range of standard tanks and the appointment of former Elson employee Doug Rodgerson, McDonald Engineers has become a real force to be reckoned with in the rectangular hot water tank market.
Spearheading the development of the CUBEflow range, Doug Rodgerson, explained “McDonald Engineers technical capabilities are widely recognised in the industry however since joining the company what has impressed me the most is their uncompromising commitment to quality and customer service.”
He continued, “The CUBEflow range of rectangular hot water tanks, will offer customers a direct replacement for Elson units. McDonald Engineers bespoke capabilities continue to allow the wide variety of products previously available.”

McDonald Engineers Deliver Impossible Bespoke Hot Water Cylinder

Bespoke Cylinder from McDonald Engineers
McDonald Engineers has demonstrated why it’s the UK’s leading manufacturer of bespoke hot water cylinders, by designing and manufacturing a highly technical cylinder that no other manufacturer was prepared to take on.
After discussing the project at length with the client, McDonald Engineers team specified an ELECTRAflow vented thermal store featuring eight immersion heaters, a solid fuel capability and two domestic hot water draw off coils.
McDonald Engineers’ Sales Director, Jamie Stewart explained, “Delivering the right cylinder for a solution not only requires a highly specialised manufacturing capability, but also the technical knowledge and design expertise is every bit as important.”
He continued, “Fortunately we are one of the few companies that have an experienced technical sales team who truly understand the full capabilities of hot water cylinders and can help clients to specify cylinders that many would write off as impossible or unfeasible.”

Pembleton Enthusiasts tap into McDonald Engineers Copper Capabilities
McDonald Engineers has demonstrated its expertise in bespoke copper products by manufacturing a 500mm spun cylinder top for fitting to a Pembleton car.
Whilst more renowned for the fabrication of high quality copper hot water cylinders, it is not unusual for the company to be asked to create copper products and components for purposes other than plumbing.
Past requests have included, copper washers, slug rings to keep slugs and snails away from garden plants, off cuts for jewellery making and copper plates for artwork etchings. But spun cylinders for a Pembleton car has to be one of the quirkier request so far.
And, instead of this being a one off request, McDonald Engineers has just received its second order… but this time all the way from the USA.
McDonald Engineers’ Sales Director, Jamie Stewart, commented “Our experience and expertise in copper manufacturing, particularly with bespoke products, enables us to take on unusual requests, such as the cylinder for the Pembleton car and deliver them cost effectively.”

Fife Family Business Introduces its Third Generation
Glenrothes based manufacturers of hot water cylinders, McDonald Engineers, has demonstrated that family businesses can continue to deliver success over the long term by welcoming its 3rd generation to the business.
David Stewart, son of Managing Director Bill Stewart, nephew of Sales Director, Jamie Stewart and grandson of previous owner Mr Stewart, has joined the company’s technical sales office after a period on the shop floor where he experienced a thorough introduction to the manufacturing process of hot water cylinders.
Introducing a 3rdgeneration into a business is no mean feat, however when you consideration that McDonald Engineers is one of the last few survivors of what was a buoyant UK copper cylinder industry, it is an incredible achievement.
McDonald Engineers has also managed to buck the recent economic downturn which has seen the construction sector one of the hardest hit and continued to deliver year on year growth despite facing unprecedented rises of some 400% in material costs.
The company’s ability to embrace change has been one of the keys to success. Incorporated in 1945 and the subject of a management buyout in 1973, past activities have included the manufacture of truck bodies, waste disposal skips, general steel fabrication and prefabricated plumbing. However, specialists in their field, the company now focuses on hot water systems with a growing focus on the renewable energy market
Working in partnership with the University of Strathclyde as part of a 2 year Knowledge Transfer Partnership, the company has also been developing its internal process to prepare for continued growth.
Managing Director, Bill Stewart, commented “There is always a sense of pride mixed with a little trepidation when you bring any member of your family into the business but David has shown an incredible enthusiasm for getting involved which made the decision very easy.”
He continued “McDonald Engineers is more than simply a family owned and managed business. We have a real family mentality from the shop floor through to our sales team and it’s this spirit that has enabled the company to be successful for such a long period.”
With such a high standard to follow, David would be forgiven for feeling a little apprehensive about working for his father and uncle, however he was delighted to be joining the team, commenting “I have grown up with company and used to business matters being a key part of our day to day family life so it’s great to now be a part of the team and hopefully help the company to continue to grow for many years to come.”
A top class cylinder for the world class National Library of Scotland
A top class cylinder for the world class National Library of Scotland
McDonald Engineers can now claim their POWERflow unvented cylinder is in a national institution following a recent project which saw one if its commercial grade cylinders being installed in the National Library of Scotland.
The POWERflow was installed as part of a routine maintenance programme and due to the height of the building, Scotland’s largest library required a 4 bar working pressure copper cylinder manufactured to their exact specification.
McDonald Engineers’ answer was to produce a commercial grade POWERflow with customised connections, to provide a higher flow rate than standard cylinders. McDonalds also amended their standard design to simplify the installation process, by positioning the connections in convenient and easily accessible locations.
Jamie Stewart, McDonald Engineers Sales Director explained why many commercial contracts were insisting on bespoke copper cylinders, “The benefits of copper in terms of its increased thermal transfer and its bacteria killing properties are well documented, however our ability to manufacture bespoke cylinders to exact specifications means that clients and architects do not need to compromise on what they require.”
He continued, “By increasing the connection sizes and upgrading the copper thickness, we can enhance working pressures to meet the demands of the project. And if you are creating a bespoke cylinder you can also look to minimise the installation time and costs by positioning connections in the perfect location.”

McDonald Engineers Supply Edinburgh’s Newest Hotel
McDonald Engineers has demonstrated its expertise in the hotel and leisure sector by installing its POWERflow commercial cylinders in Edinburgh’s newest hotel.
Situated in the Bruntsfield area of the city, The Links Hotel, has just undergone a major refurbishment spending in excess of £1million pounds with all 22 of the rooms undergoing a complete transformation.
And with such a large investment, owners Kingdom Hotels were determined to install a quality hot water system that would meet its exemplary standard of quality.
Copper’s thermal conductivity, which is almost 30 times greater than that of Stainless Steel enabling it to heat water to higher temperatures in a far shorter period of time. Add in its superior bacteria killing properties and its easy to see why copper is fast becoming the material of choice in the hotel industry.
McDonald Engineers’ Sales Director, Jamie Stewart, explained, “One of the biggest problems that hotels face is a lack of pressure and a drop in temperature when there is high occupancy levels, particularly at peak times.”
POWERflow’s ability to deliver mains pressure with superb heat recovery rates coupled with its reliability ensures peak performance, no matter what demands are placed upon it.
“We are delighted to have provided the management team at the Links hotel with the confidence and peace of mind that their guests won’t have to endure a cold or weak shower in the morning!”
World Heritage Site calls upon McDonald Engineers
McDonald Engineers has added World Heritage Site and the birth place of Sir Winston Churchill, Blenheim Palace, to its growing portfolio of clients with the installation of a number of their ECOflow heat pump cylinders.
Designed specifically to work with heat pumps, the ECOflow is quickly becoming increasingly popular in both the commercial and residential sector.
Sales Director, Jamie Stewart said “The industry is starting to turn with a notable increase in the number of heat pump cylinders being installed.” He continued “We have long preached the benefits of using Copper cylinders but with Heat Pump technology, Copper really does come to the fore”
Copper’s thermal conductivity rating is almost 30 times greater than that of stainless steel which helps to optimise the heat transfer process and maximise efficiency.
So, not only will Blenheim Palace be helping to conserve this national site of interest but they will be helping to conserve the environment and their long-term budget too!
