Bespoke Cylinders and tanks


McDonald Water Storage have been providing bespoke designed vented and unvented hot water cylinder solutions for over 75 years.

Manufacturing from copper provides the flexibility of design for the customer. In these days of mass produced ‘standard’ cylinders, having the option to bespoke design a hot water cylinder or tank to suit the specific application, whether it is the size or tapping configuration, it is a major benefit to both the installer and homeowner.

A bespoke cylinder can be designed to suit the space available, where a ‘standard’ product will not fit. Therefore bespoke models can be tall slimline design, short wide design or even a horizontal configuration.

It may be that the installer requires the tapping positions adjusting to suit either a replacement or even designed to accommodate additional heat sources.

A bespoke cylinder or tank can provide benefits both to the homeowner and installer.

From a homeowners perspective, the space available for the installation may be restricted, and standard products will not fit into the required location. This has become more apparent in recent years where properties had previously switched to combination boilers and utilised the original cylinder cupboard. However, with a cylinder now being required to maximise renewable heat sources, other locations may be required, including loft spaces. Having a bespoke designed cylinder provides the solution for the homeowner to incorporate the technologies they require.

For installers, bespoke cylinders not only overcome any space restrictions, but also, having the tapping connections in the positions they require, helps to reduce the installation time, freeing up time for other installations.

Our technical team at the head office in Glenrothes are able to assist you with the specification requirements of a bespoke cylinder or tank.

A member of the team will talk through your volume, dimensional and tapping requirements, including the required heat sources, to provide the perfect hot water solution to meet your installation requirements.

In addition to domestic products, our expertise within commercial cylinder manufacture, ensures any cylinder up to 100,000 litres is designed to meet your specific requirements.

Once the specification has been discussed and agreed with a member of the technical team, the bespoke domestic cylinder or tank can be manufactured within 5 working days, and often quicker where it is a matter or urgency.

For commercial applications, with cylinders up to 3000 litres, we can still manufacture in as little as two weeks.

McDonald Water Storage manufacture bespoke cylinders up to 3000 litres in copper, with mild steel and stainless steel units available up to 100,000 litres.
