McDonald Engineers Offer New Low-Cost Lagging option on Calorifiers
McDonald Engineers have responded to the changing market requirements with the introduction of a new low cost lagging option on its range of calorifiers.
The new low cost lagging uses foil-backed rockwool insulation to deliver a GWP rating of <1, making it an ideal solution for commercial environments.
McDonald Engineers have continued to maintain their position as one of the UK’s leading manufacturers of hot water cylinders thanks to their ability to remain one step ahead of the competition when it comes to new products.
2010 has already seen the launch of their Renewable Energy range and the introduction of the ECOflow heat pump cylinder which was the first cylinder of its type to be available as a standard stock item.
Sales Director at Mcdonald Engineers, Jamie Stewart, explained “One of our key strengths is the close working relationships we have with our clients which enables us to identify changes in demand and respond quickly with new solutions.”
He continued, “We strive to provide our customers with uncompromising quality and value and it is only by continuously looking at other options and assessing our current methods that we are able to maintain our enviable position in the market”.

Dual Coil Calorifiers Installed for Department for Communities and Local Government

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.”
