Filed under: Thermal Store, hot water cylinder 

McDonald Engineers have launched a new brochure to support the changing market demands of market leading thermal store, THERMflow.

Thermal stores are becoming an increasingly popular solution for hot water cylinders, not only because of its ability to deliver mains pressure hot water with limited maintenance implications, but also its ability to handle multi-fuel and renewable energy installations.

Add in the superior heat transfer and bacteria killing properties offered by copper together with McDonald Engineers world class service, and it’s easy to see why the THERMflow is becoming one of the most successful Thermal Stores on the market today.

McDonald Engineers’ Sales Director, Jamie Stewart, explained “The increase in energy costs has quite literally fuelled the demand for alternative heat solutions such as solar, heat pumps and wood burning stoves. And as people look to maximise the efficiency of their heating systems, they are exploring every means of recovering any heat available”

He continued, “Our experience in multi-fuel installations is widely respected in the market and our clients have come to rely on the advice and expertise provided by our technical sales team to deliver the most effective and efficient solution possible.”

The THERMflow system is available in a wide range of sizes however McDonald’s custom designed service enables clients to tailor the cylinder to their exact requirements with multiple coils, positioning of connections and sizing.

How to Prevent Legionella in Hot Water Cylinders

July 24, 2012 by admin · Leave a Comment
Filed under: Legionella Water, hot water cylinder 

Legionella remains relatively uncommon in the UK, however when incidents do occur, the finger of blame is often pointed at bacteria in stored water.
The risk of bacteria developing within a storage device will be largely dependent on 4 key factors

1.    The Movement of the Water
Water that is stagnant for a prolonged period of time can be a breeding ground for bacteria such as legionella, which is why the correct sizing of a cylinder is a key element of any project. The focus of most specifications is to ensure the user has hot water on demand, however specifying cylinders which are too big for a particular application can result in stagnating water. In commercial applications, a circulating “de-stratification” pump can be fitted to ensure even temperatures throughout the cylinder.

2.    The Temperature of the Water
The critical temperature in which Legionella can become a real danger is between 20°C and 45°C. This is due to the fact that Legionella bacteria remains dormant below 20°C, does not multiply above 50°C and is killed off above 55°C.  Whilst most hot water cylinders will be set to ensure the water temperature remains higher than 60°C, inefficient cylinders and renewable energy applications can often be subject to lower temperatures.

3.    The Efficiency of the Cylinder
It is vital the hot water cylinder is regularly maintained to ensure that all connections are clear and water is flowing freely and to the required pressure.  Stagnant water or lower temperatures can all increase the chances of bacteria forming in the cylinder.

4.    The Material Used in the Cylinder
Tests showed that after 7 days of immersion in water, 80% of stainless steel and 90% of plastics were coated in a biofilm, where bacteria begins to form.

Copper’s natural ability to kill 99.9% of bacteria such as Legionella , MRSA and ecoli within 2 hours enables clients to protect the well being of the patients, children and employees from this potentially life threatening disease. Similarly, the concentration of E. coli when tested after the 7 days was 100 times lower on the copper than the stainless steel or plastic.

In tests, it took 34 days for E. coli 0157 to die on stainless steel, 4 days on brass and just 4 hours on copper.

In summary, the risk of Legionella can be minimised by taking the following actions:
•    keep the system clean;
•    keep the water moving;
•    keep the water below 20°C or above  55°C
•    specify copper hot water cylinders

McDonald Serve Up Perfect Solution for Major Brewery

May 13, 2011 by admin · Leave a Comment
Filed under: Unvented Cylinder, hot water cylinder 

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.

Check out McDonald Engineers’ POWERflow range of unvented cylinders or call our technical sales team on 01592 611123.

McDonald Engineers continue to blaze the training trails

October 12, 2010 by admin · Leave a Comment
Filed under: Training Course, hot water cylinder 

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.

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 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.
