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.”

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.

Thermflow Hot Water Cylinder Range
McDonald Engineers’ THERMflow vented mains pressure system has been hailed as the UK’s most flexible hot water cylinder on the market today due to its unrivalled ability to integrate with multi fuel installations including electric, gas, oil, solar and solid fuels.
The rising cost of gas and electricity together with the global movement towards more sustainable energy sources is seeing a growing demand for flexible hot water systems, such as THERMflow, that can enable the core energy sources to be supplemented with more sustainable fuels, such as solar and wind, as well as solid fuel sources.
Manufactured using McDonald Engineers advanced copper manufacturing system, the THERMflow system delivers all the bacteria killing properties and reduced running costs associated with copper and is available in a wide range of sizes.
And demonstrating McDonald Engineers’ position as one of the UK’s leading manufacturers of copper cylinders, the THERMflow product can be custom designed to almost any height, a wide range of diameters and with any number or bespoke positioning of connections to facilitate those unusual or awkward areas.
McDonald Engineers’ Managing Director, Bill Stewart, explained “We are receiving a growing number of enquiries from architects, consultants and end-clients across the UK who are now looking at integrating alternative fuel sources to supplement gas and electric which is offered as standard on our THERMflow system.”
He continued, “However the THERMflow system continues to be one of the UK’s most popular vented mains pressure system with its integrated primary feed and expansion tank, zero maintenance requirement and superior energy efficiencies.”
