Mcdonald Water Storage

McDonald Water Storage is the UK’s most experienced manufacturer of copper hot water systems. We design and manufacture a full range of solutions, including vented and unvented cylinders, thermal stores, calorifiers, heat pumps and solar cylinders, plumbing units, back boilers, rectangular tanks, and electric wet systems. We support large, complex projects across the UK. We also specialise in bespoke cylinders built to your exact requirements. That combination matters. It means you’re working with a manufacturer that understands standards, constraints, and real-world installation challenges, not just catalogue products. Copper sits at the heart of what we do. It’s durable, recyclable, and it supports good hygiene and long service life. Copper has been trusted for hot water storage for centuries, and it remains a dependable choice where performance, reliability, and confidence matter. If you’re specifying, installing, or maintaining hot water systems, this is what we’re built to support.
