Filed under: Buffer Tank, McDonald Engineers News, Multifuel Hot Water System
McDonald Engineers’ Managing Director, Bill Stewart, has set off on an extraordinary challenge to scale Mount Kilimanjaro, the highest mountain in Africa, and raise £20,000 for charity in the process.
Bill together with his wife Mairead, will join a team from the Rotary Club of Kirkcaldy as they take on the challenge of a lifetime to raise funds for projects in Tanzania that the Rotary has been supporting.
Bill, more renowned for his love of cars as opposed to hill walking, explained,” Not being natural mountaineers we have been in training to raise our fitness for the event, though we are aware the threat of altitude sickness will be the biggest challenge.
He continued “We would like our effort to do more good than just allow us to bore our friends with stories about how long Mairead couldn’t wash her hair for or how sore my feet were.”
You can help Bill to achieve his £20,000 target and provide him with the extra motivation he requires to conquer the mountain by donating now at http://uk.virginmoneygiving.com/charities/rotaryclubofkirkcaldycharitabletrust

Celebrity Installation for ECOflow Heat Pump Cylinder
Filed under: Multifuel Hot Water System, heat pump cylinder

ECOflow Heat Pump Cylinders
ECOflow has continued to receive rave reviews from specifiers and installers alike since its launch earlier in the year. However the dedicated heat pump cylinder has now officially achieved celebrity status, after being installed in the home of a star who is never out of the UK media.
The ECOflow was the first choice for the company working on the refurbishment of the home of Aussie heart throb, Peter Andre, which included the latest heat pump technology and required a high quality hot water cylinder that could deliver maximum performance.
With a pre-fitted high performance heat pump copper coil, compression fittings fitted as standard and insulated with a white cased finish that delivers a GWP rating of less than 1 and an ODP of zero, it’s no wonder that the ECOflow is the rising star of the heat pump market.
McDonald Engineers, Sales Director, Jamie Stewart, explained “ECOflow provides the client and the installer with so many benefits. Not only is it easy to specify and install, the system is based on our highly successful POWERflow 2000 model which means that it’s a solution that delivers unbeatable reliability, durability and performance.”
The ECOflow cylinder is also manufactured from copper and features a high efficiency finned copper coil, which has a thermal conductivity rating that is 30 times greater than stainless steel, to enable the water to heat up quicker, making it an ideal choice for the renewable energy.
Jamie continued, “Many heat pump manufacturers are now recommending that installers should only use copper cylinders in conjunction with their products as they recognise the enormous improvements on performance that coppers offers. The heat transfer process is clearly a key factor, however with most heat pumps achieving lower water temperatures than that of traditional fuel sources, copper’s unrivalled bacteria killing properties also means that a copper cylinder is also a safer 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.

Dual Coil Calorifiers Installed for Department for Communities and Local Government
Filed under: Calorifier, Copper Cylinder, Electric Wet Central Heating System, Multifuel Hot Water System, Unvented Cylinder, Vented Mains Pressure System, heat pump cylinder
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.”

Taking Alternative Fuel Hot Water Solutions To A New Level
Filed under: Multifuel Hot Water System, Renewable Energy Cylinders, Unvented Cylinder
McDonald Engineers has been at the forefront of hot water systems for decades and, as well as an extensive range of products available for immediate despatch, have established a reputation in the market place, for being the specialists in bespoke hot water cylinders for multi-fuel and alternative fuel applications.
So when a specialist contractor was developing a pre fabricated toilet and wash block for a project being shipped to Africa, which needed to heat the water by burning the waste from the toilets in an incinerator, McDonald Engineers was their first port of call.
With the African climate requiring a comparatively lower level of hot water storage, McDonalds developed and supplied eight bespoke 75 litre POWERflow 2000 Unvented Cylinders to accommodate the fuel source, using its high performance coils for maximum heat transfer.
McDonald Engineers Project Manager, Dean Morrison, explained “Whilst we have manufactured a large number of bespoke cylinders with a multitude of fuels, from solar thermal to heat pumps, this is by far the most unusual fuel source we have ever worked with.”
He continued, “Most importantly the client is delighted with the end result and it goes to show the flexibility of the company, as well our ability to develop solutions that can transfer the heat from virtually any fuel source.”

McDonald Engineers is enabling architects and consultants to reach their energy targets with the launch of their dedicated range of hot water systems that are designed to be used in conjunction with renewable energy sources such as solar energy and heat pump technology.
The Renewable Range features its POWERflow2000 system, the THERMflow range, the ELECTRAflow electric wet central heating system, the TIMEsaver plumbing unit, its full range of Calorifiers and of course its original Solar Save system which was the first in the range to be designed with high specification coils and probe pockets to maximise the benefit of solar energy.
The company, which has been at the forefront of hot water systems since 1945, has been developing cylinders designed for solar energy since the early 70s and has established itself as one of the most respected manufacturers in the industry.
Managing Director, Bill Stewart, said, “It is vital that we all play our part in reducing the energy we are using and we are delighted to launch this exciting range of products that we hope will enable designers, specifiers and contractors to achieve their energy saving obligations.”
A key element in the design of the range is the recognition that, in many instances, solar energy is unable to act as the single source and provide the level of power required to heat every application.
McDonald Engineers have therefore developed a multi-fuel system, such as in their THERMflow range, which can work with a number of energy sources and in doing so, reduce the ongoing running costs.
Bill continued, “By designing a system that can work with a multiple of fuels we can attempt to draw the energy from every available source thereby delivering the most cost effective hot water solution.”
The company is also available to incorporate a number of high efficiency coils into its POWERflow 2000 range to improve the effectiveness of solar, heat pumps and boilers in delivering the required levels of energy.
