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.”

Mitsubishi Ecodan Insist on Copper Hot Water Cylinders for their Heat Pumps
Filed under: Calorifier, Copper Cylinder, Electric Wet Central Heating System, heat pump cylinder, hot water cylinder
Mitsubishi, one of the UK’s leading manufacturers of heat pumps, has reinforced copper’s superior performance in renewable energy systems, by insisting that only copper hot water cylinders, such as McDonald Engineers POWERflow 2000 unvented cylinders, are used in conjunction with their new advanced Ecodan heat pump systems.
The news adds further weight to McDonald Engineers’ campaign to promote copper’s green credential when it comes to heat transfer and recyclability - as well as its bacteria killing properties.
McDonald Engineers’ copper cylinders are used widely with Mitsubishi’s Ecodan products and also a wide range of other Geothermal and Air Source Heat Pumps, due to the company’s unrivalled reputation in the Renewable. With over 65 years experience in developing its product range to maximise the heat transfer process, McDonald Engineers has the skills, knowledge and expertise, to develop bespoke solutions to suit renewable energy applications.
McDonald Engineers’ now offer solar and heat pump compatibility with its POWERflow 2000 Unvented Cylinder, THERMflow Thermal Store, ELECTRAflow Electric Wet System, SOLARsave Pre-Plumbed Solar System and TIMEsaver Plumbing Unit, as well as its full range of Calorifiers.
However with the company’s unique ability to manufacture bespoke hot water cylinders to a client’s exact requirements, McDonald Engineers is fast becoming the copper cylinder manufacturer of choice when it comes to heat pumps and renewable energy solutions.

McDonald Engineers Introduce the Renewable Ready Range of Hot Water Systems
Filed under: Copper Cylinder, Electric Wet Central Heating System, Multifuel Hot Water System, Vented Mains Pressure System, hot water cylinder
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.

ELECTRAflow wet central heating system
ELECTRAflow’s 100% heating efficiency combined with its low installation costs has made it the perfect choice for housing associations and contractors looking at developing or refurbishing new houses, flatted developments and properties in rural areas with no natural gas supply.
Manufactured by leading copper cylinder specialist, McDonald Engineers, The ELECTRAflow system’s integrated electric boiler and copper storage cylinder is both cheaper to install than a heat pump, requires no annual boiler maintenance and is more efficient than other forms of heating such as night storage, oil and LPG providing significant cost savings throughout its lifetime.
The compact system also requires no flue making it easy to situate and ideal for listed buildings and high rise flats.
Available in vented and unvented systems, ELECTRAflow can also be integrated with additional fuel types including solar panels, solid fuels and can used to power underfloor heating as well as standard radiators.
McDonald Engineers, Managing Director, Bill Stewart, commented, “The days of electric heating solutions being prohibitively expensive to run are over with the robust, intelligent and highly cost effective solution offered by ELECTRAflow particularly when combined with solar energy and economy tariffs from the utility companies.”
