McDonald Serve Up Perfect Solution for Major Brewery
McDonald Engineers has demonstrated its expertise in developing bespoke solutions by designing and manufacturing a new system for one of Scotland’s largest brewers who were experiencing the problem of intermittent hot water.
Working in conjunction with one of the maintenance contractors onsite, one of McDonald Engineers’ technical sales team visited the site and identified the issue.
The hot water, being supplied to the toilets via 3 cylinders, was being heated by steam through a heating coil. However as the steam shuts down at various point throughout the day, the staff were regularly finding themselves without hot water.
McDonald Engineers recommended that the existing cylinders were replaced with bespoke POWERflow direct cylinders, featuring additional immersion heaters and custom connections.
McDonald Engineers, Sales Director, Jamie Stewart, explained “Our technical sales team is regularly called in by clients and contractors to assess problem systems and develop solutions that will meet the projects requirements.”
He continued, “It’s one of the reasons why we have established strong relationships with our clients, many of whom now see us more as their manufacturing partner as opposed to just a supplier.

McDonald Engineers continue to blaze the training trails
Whilst home to some of the most experienced copper brazers in the country, McDonald Engineers recently undertook training from their brazing rod supplier. They provided an insight into the latest developments in brazing, as well as going over the advanced methods that the company employs on a daily basis.
This method of joining metals using heat and a filler has been practised by McDonald Engineers for many years, however in a bid to continually develop and keep the standards high, McDonalds proactively set aside the time to hone their skills.
Some of the knowledge shared, illustrated that there is always room for improvement with small tips being given along the way. Needless to say, with the newly acquired knowledge, the engineers quickly tweaked their methods to ensure that all clients gain from the benefits of best practice.
Elaborating on the benefits, Jamie Stewart, Sales Director at McDonald Engineers said, “These types of programmes are an essential part of our development strategy that provide enormous benefits to everyone. We improve on the quality of our products and processes. In turn our clients receive a much quicker and efficient production service”.
He continued, “If anyone thinks that they are above training, they have got to be kidding themselves!”
This course of continuous improvement adds to the ongoing commitment that McDonald Engineers have invested over the preceding years.

Filed under: Multifuel Hot Water System, heat pump cylinder, hot water cylinder

ECOflow Heat Pump Cylinders
McDonald Engineers has become the first UK manufacturer to launch an off the shelf hot water cylinder, specifically designed to work with heat pump technology.
The launch of its ECOflow unvented cylinder for heat pumps comes as a result of the growing demand it’s receiving from heat pump installers across the UK and beyond, who are looking for a tried and tested solution which is available as an off-the-shelf product, which comes with all the connections required for heat pump installations as standard.
Based on its market leading POWERflow 2000 unvented copper cylinder, ECOflow also comes pre-fitted with McDonald Engineers’ high performance heat pump copper coil and is insulated with a white cased finish delivering a GWP rating of <1. An optional integrated buffer vessel, which sits below the cylinder offers the advantage of a small footprint which suits many architects and specifiers who have limited space to work with.
McDonald Engineers’ Sales Director, Jamie Stewart, explained, “We have been making bespoke heat pumps cylinders for many years, however as the renewable energy market has grown, more clients have been asking for a standardised solution which offers the cost savings associated with larger production runs.”
He continued, “Copper hot water cylinders are widely recognised as the best and most cost effective solution to be used in conjunction with heat pumps. A leading heat pump manufacturer reckoned using an ECOflow type cylinder could save up to £180 per year on running costs. This is a hugely significant factor in ensuring the customer is given the best and cheapest to run unit.
The copper hot water cylinder market has already been given a major boost by Heat Pump manufacturers. Many recommending their products be used in conjunction with copper hot water cylinders due to the superior heat transfer properties offered by the material, as well as its bacteria killing properties and its recyclability.
The company has already received a positive response from existing clients and hopes to develop its position in the growing renewable energy market even further.
McDonald Engineers has been manufacturing hot water cylinders and supplying the UK and further afield from its base in Scotland since 1945. They have been at the forefront of hot water cylinder development for renewable energy applications for the last 4 decades.

PLATEflow system scores top marks by controlling peak flow rates in school sports centre

PLATEflow Hot Water Cylinder
Pupils were not the only ones to gain top marks in school recently as McDonald Engineers helped a client who was faced with the challenge of providing a buffer for a short period of peak demand linked with a Plate Heat Exchanger to provide a steady flow rate.
McDonald Engineers worked with the client, providing their expert advice and guidance to assess all the alternatives before developing the perfect solution using their PLATEflow system.
McDonald Engineers’ Sales Director, Jamie Stewart, explained “At McDonald Engineers we like to put all the available options down on the table and come up with the best possible solution for our clients. It’s our ability to listen to our clients requirements, remain flexible and provide the best solution based on the situation at hand that keeps them returning time and time again.”
The result was to supply a PLATEflow unit with a 550 Litre Vented Grade 2 cylinder and Plate Heat Exchanger. Thanks to the off-site pre-assembly the contractor was able to dramatically reduce installation time.
The McDonalds PLATEflow system is specifically designed to supply hot water in situations where demand can vary over the course of a day and is ideal for use within hotels, hospitals, factories and in this case, a School Sports Centre in Edinburgh. It effectively decreases the amount of stored hot water required, while still delivering peak flow rates as demanded.
And with the PLATEflow system there are plenty of options available to offer. The PLATEflow can be supplied as either a vented, tank fed unit, or is suitable for unvented applications, when fed from the mains or a boosted cold water supply.

Filed under: Copper Cylinder, Thermal Store, hot water cylinder

THERMflow Thermal Stores from McDonald Engineers
Dispelling the myth that bespoke cylinders are just for one-off projects, McDonald Engineers has enabled one Scottish Local Authority to save a significant amount of time and installation costs on a project which required over 400 thermal stores.
By working closely with the project team, McDonald Engineers were able to re- position several key connections on its standard THERMflow Thermal Store, to suit the incoming pipework and make it easier for the installation team to access.
In doing so, the installation team were able to install the cylinders much quicker and with less materials, saving time, money and hassle on site.
McDonald Engineers’ Sales Director, Jamie Stewart, explained, “Our flexible manufacturing process is renowned for being able to produce one off cylinders quickly and efficiently. However there is a growing client base, who now realise the enormous benefits that can be achieved just by tweaking the design of existing products for large volume contracts.”
He continued, “By making simple changes, such as repositioning the connections, clients can achieve significant time and material savings. When you add up all the savings, whether it is on a contract of 20 homes or 20,000 cylinder installations, it’s easy to see how much can be saved.”

Unvented Cylinders Experience Dramatic Growth In Demand From Refurb Market
Filed under: Copper Cylinder, Unvented Cylinder, hot water cylinder
Unvented cylinder systems are now experiencing an unprecedented growth in the replacement market, as many installers recognising that a combi system isn’t always the best choice.
Since figures published by the Hot Water Association in 2008, showed that mains pressure hot water systems, reached close to half of the total hot water storage market, for the very first time, the growth has continued as changing demands favour the benefits offered by unvented systems.
Whilst combi systems can provide an instantaneous hot water solution, very few can exceed 20 litres per minute, or cope with demand from multiple outlets.
McDonald Engineers Sales Director, Jamie Stewart, explained ” Modern households are expecting their hot water systems to be capable of delivering more hot water, at higher flow rates, simultaneously to multiple outlets and with limited loss of performance.”
He continued, “As a result we have seen enquiries for our POWERflow 2000 unvented cylinder rise considerably from installers, house builders and local authorities who are beginning to question the attractiveness of the combi system. We have also seen a dramatic increase in sales of our THERMflow Thermal Storage Unit. This gives the benefits of Mains Pressure Hot Water at the tap, but with a Vented Store. This type of unit is ideal for all boilers and can also be used when people have an additional Solid Fuel heat source.”
