Copper Washers for Council Contract
McDonald Engineers were recently approached by a merchant who had a bit of unusual request - ‘Can you supply copper washers for a council who needs them for a particular contract they are working on?’
Copper Washers
As you may be aware, copper washers are often used in piping, electronics and biomedical applications as they are a great conductor of heat and when very pure, a good conductor of electricity. Copper is also quite a malleable material which means that when a copper washer is crushed between two surfaces, it can fill any imperfection.
As specialist copper manufacturers, we of course rose to the challenge and delivered the project on time and to everyone’s satisfaction. “We were delighted to fulfil the council’s requirements and demonstrate that we can apply the same quality of workmanship and flexibility to such unusual requests as we do to our range of hot water cylinders” commented Sales Director Jamie Stewart.
He continued, “In an industry where every second counts, it is imperative that our products are turned around quickly. Many installers and specifiers don’t realise just how quickly we can make copper cylinders for them with most orders despatched within two to three days. We also stock over 90 different sizes of cylinders for immediate availability.”
So, the next time you need some copper washers, or indeed require any product manufactured from copper, contact our technical sales team on 01592 611123 who will be only too happy to help.
Dual Coil Calorifiers Installed for Department for Communities and Local Government

McDonald Engineers’ expertise in delivering energy efficient hot water systems for commercial environments, was put to the test by the Department for Communities and Local Government at their headquarters in central London.
Four Calorifiers at Eland House
With a total focus on energy efficiency by the design team at Eland House, formerly the Office of the Deputy Prime Minister, McDonald Engineers manufactured and supplied four dual coil POWERflow commercial calorifiers for the refurbishment project.
The 1320 litre calorifiers were designed to work with two fuel sources. A Heat Pump was being used as the primary heat source and the units were therefore fitted with a high efficiency copper heat exchanger, to maximise the heat transfer from the heat pump’s lower flow temperature. A back up heat exchanger, for a normal boiler was added, to supplement the energy when required.
In line with the latest recommendations from many heat pump manufacturers, both the cylinders and the coils were manufactured from copper. This provides significant benefits in terms of maximum heat transfer, as well as boasting superior bacteria killing properties.
McDonald Engineers’ Sales Director, Jamie Stewart, explained “As more projects aim to maximise the energy efficiency of the hot water system, we are seeing a rise in enquiries from companies installing heat pumps who recognise that copper can deliver superior results.”
He continued, ” Copper is fast becoming the material of choice for hot water systems using multiple fuel sources such as heat pumps. Copper’s thermal conductivity is almost 30 times greater than that of Stainless Steel. This means it can heat water to higher temperatures in a far shorter period of time.”
With access to the boiler room extremely limited by doorway space, but a specified amount of storage required, McDonald Engineers were provided with the maximum dimensions that would fit. The company ensured every millimetre was utilised, by manufacturing the cylinders to extremely tight tolerances. The Calorifiers were then lagged on site.
Jamie added, “The client was delighted with the end result and our ability to maximise the size, commenting that if there had been a coat of paint on the cylinder, it would not have gone through the door.”
