11.04.2013 McDonald Engineers Deliver Unvented Cylinder for Historic Castle

McDonald Engineers have shown their ability to deliver bespoke solutions for every type of application, by designing and manufacturing a 360 litre unvented POWERflow cylinder for a 16th century castle.


Invercauld Castle was originally built as the home of the Clan Farquharson however it now operates as a luxury shooting and fishing lodge in Aberdeenshire.

McDonald Engineers were recommended to the owners of Invercauld Castle when they chose to upgrade the direct vented system that supplied hot water throughout the castle.
