McDonald Engineers’ star in BBC feature on Geothermal Heat Sources

Geothermal Heat Pumps

McDonald Engineers’ unvented POWERflow cylinder has been featured on the BBC website as part of a feature on the use of Geothermal Heat Pumps, as a means of delivering more energy efficient heating.

The cylinder featured, was part of a project in Glasgow, which McDonald Engineers was involved with over a decade ago.  According to the residents,it continues to deliver significant savings, equating to over £500 less than the average energy bill in Scotland.

The BBC was reporting on a proposed new scheme for Glasgow, which aims to harness the heat found in water in abandoned coal mines below the streets of the city and provide a new fuel source for homeowners.

McDonald Engineers worked with the consultant engineer, to design and manufacture the cylinders to work most efficiently with the Geothermal heat pumps.  The highly efficient copper coils in their POWERflow Unvented Mains Pressure System, are the key to extracting the most heat, out of the lower input temperatures from the heat pumps.

McDonald Engineers’ Sales Director, Jamie Stewart, explained “We were delighted to see our cylinder featured so prominently in what was one of the first installations of Geothermal Heat Pumps in Scotland and goes a long way to demonstrate the longevity of our cylinders.”

He continued, “Copper cylinders continue to be recognised as the recommended solution for heat pumps.  This is due to the unrivalled thermal transfer properties and their superior ability to kill off harmful bacteria, which can be found in water at lower temperatures.”

McDonald Engineers has continued to develop its technology since the Glenalmond Street project and now offers its ECOflow system, the UK’s first dedicated hot water cylinder for heat pumps.”
