About McDonald Water Storage

McDonald Water Storage is one of the UK’s leading manufacturers of hot water systems with an unrivalled reputation for quality and service. As a privately owned, independent manufacturer of hot water tanks, we are committed to delivering a flexible service which is designed to meet the needs of the current economic climate.

This is reflected in our extensive product range and our ability to customise any cylinder to your needs, whether it’s a one-off bespoke cylinder or a large contract which would benefit from custom sizes or connections for ease of installation.

Our experience in designing and developing hot water cylinders for renewable energy sources is second to none and our expertise is regularly called upon by architects, engineers, specifiers and installers to ensure the most effective and efficient cylinder is delivered.

Whilst our main material of choice remains to be Copper, thanks to its superior heat transfer, environmental benefits and antimicrobial properties, we also offer our range of stainless steel unvented cylinders for those projects which are working to tight budgets.

Quality remains at the forefront of all our activities, from the grade of material through to the systems and processes employed. We operate a quality system which complies with BSEN ISO 9002. The company also holds WRc (Water Research Council) certificates for the STEELflow and POWERflow range of unvented systems.
