The unique design of the CUBEflow Thermal Store not only provided a homeowner with improved hot water performance but also a space saving solution.
Sandhurst Plumbing & Maintenance were contacted by a new client in Soho, who came to them through a recommendation from another one of their satisfied customers. The client had been experiencing persistent problems with their existing hot water cylinder, including poor water pressure and inconsistent temperature, and asked us to provide a modern, reliable replacement.
One of their engineers attended site to assess the installation and discuss options with the client. They had received a quotation from another company to install an unvented hot water cylinder however, this was not suitable for their property. The presence of a plastic overflow pipe meant that an unvented installation would not comply with Building Regulations Part G3.
This is a common mistake made by some installers, especially in apartment applications.
In addition, the restricted cupboard dimensions created further challenges that required a tailored solution which could not be met by a traditional cylinder.
Having worked with McDonald Water Storage for many years, Sandhurst Plumbing knew they could provide the right product to meet these requirements. They specified and installed a 150-litre Electric Thermal Store CUBEflow Coral E – a compact unit designed to deliver mains-pressure hot water within limited spaces, while remaining fully compliant with regulations.
The thermal store system allowed the property to remain open-vented, while still providing excellent water pressure and a consistent supply of hot water. To complete the installation, the installers replaced the outdated timer, ensuring their client had full and efficient control over their new system.
Tony Bradley, Managing Director of Sandhurst Plumbing and Maintenance said “The result of installing the McDonald CUBEflow system was a modern, space-efficient, and regulation-compliant hot water solution. The client was delighted with the installation, enjoying both improved performance and peace of mind with their upgraded system.”
