Replacement Elson Units Meet Exact Requirements

Optivo Case Study

McDonald Water Storage has enabled Optivo Housing to avoid the disruption and additional costs of changing systems by designing, manufacturing and supplying an exact replacement for an existing Elson Amethyst system to fit within an extremely tight cupboard space.


Optivo Housing were looking to replace the existing Elson Amethyst tank. However as they were to be installed in extremely tight cupboard space they struggled to find like for like or suitable replacement, and alternative cylinder unit options were not feasible due to space restrictions.


The site was surveyed by McDonald Water Storage team, and provided a full design showing connection layout and sizing. We manufactured and supplied CUBEflow Indirect Sealed System units to the exact design on the same machinery as original Elson Amethyst units had been manufactured on. The unit was perfectly sized to fit within tight space, allowing the installers to utilise the existing pipework which minimised the installation costs and provided a quick and easy installation.

The homeowners not only benefited from the minimal disruption during the replacement process, but also had reduced running costs through improvements in efficiency and heat losses.


“I searched the market for a replacement Elson tank without success. Every other offering wanted to change to a cylindrical tank. Finding McDonald Water storage was fantastic, especially as the product is designed specifically to provide a like for like replacement and manufactured using the previous Elson Copper machinery for extra peace of mind.”
