Major Contract Secured for CUBEflow Rectangular Tanks in Sussex

Rectangular Hot Water Tank Sussex

McDonald Engineers UK has secured a major contract for the production of 26 custom designed CUBEflow indirect thermal stores for the refurbishment of a retired housing development in Sussex.

Working closely with the end client and consultant on the project, McDonald Engineers UK surveyed the existing Elson units to assess connection layouts before manufacturing a trial 100 litre unit to assess the suitability and ease of installation.

The test was extremely successful with the Property Manager overflowing with comments on how well the system was performing.

After assessing the trial installation, McDonald Engineers amended the design of the system slightly to reduce the size of the tanks to 92 litres, which provided more room in the cupboard where they were being fitted, whilst having no impact on performance or demand.

An additional 115 litre rectangular tanks was also manufactured and supplied to the property managers office, which had a slightly higher water demand.

McDonald Engineers’ Managing Director, Jamie Stewart, explained, “We have firmly established ourselves as the UK’s market leader for rectangular tanks thanks to our ability to manufacture and supply exact replacement of Elson units.”

He continued, “Our ability to design and manufacture bespoke units to meet the exact requirements of the project, such as in the case of this particular project, enables the client to get the optimum hot water storage system, whilst reducing the installation time for the contractor and minimise any down-time which can be critical for housing associations, retirement homes and care homes.
