Uponor has supplied custom-specified heat interface units (HIU) for two retirement living developments in Southsea, Hampshire, and St Albans, Hertfordshire, as part of a solution jointly developed by McCarthy & Stone, the plumbing contractor and Uponor.
Designed, specified and installed by GP Plumbing to McCarthy & Stone’s requirements, the units will help deliver maximum energy efficiency from the four 150kW and three 120kW gas boilers installed as a central plant, helping McCarthy & Stone achieve its objectives of maximising comfort for residents while minimising operational costs and service charges.
The specification follows a long-standing supply relationship between Uponor and GP plumbing for the installation of Uponor MLC solutions in McCarthy & Stone developments. Along with the HIU units, the Uponor MLC plumbing range has also been included in the specification for all water distribution networks from the central plant to each apartment at both schemes.
Matt Long from GP Plumbing explained:
“We have worked on similar projects for McCarthy & Stone for around 25 years and, historically, the Part-L brief for the mechanical installation has usually called for renewable energy, such as air source heat pumps, providing the energy source for wet under floor heating and hot water to apartments and communal areas.”
“For the Southsea and St Albans projects, the Part-L brief was to install gas as the main energy source for the heating and hot water and we worked in partnership with both the client and Uponor to develop the ideal solution.”
“We already trusted Uponor’s design innovation, quality standards and technical support having used the company’s MLC system for some time, so it was no surprise that we were impressed by their HIUs too, which are an ideal fit in terms of energy efficiency, value engineering, resident safety and resident comfort.”
The Southsea development combines McCarthy & Stone’s ‘Retirement Living Plus’ apartments for the 70+ age group with ‘Retirement Living’ apartments, while the St Albans scheme is exclusively for Retirement Living Plus residents aged 70+.
Both buildings have been designed with energy efficiency in mind with McCarthy and Stone’s energy consultants. With a well-insulated airtight building fabric and a mechanical ventilation system with heat recovery, each development comprises one and two-bedroom apartments. Heating and domestic hot water is included in the residents’ service charge for their apartment and the Uponor HIU units will help to ensure high levels of comfort for residents, while providing cost efficient running costs for McCarthy & Stone’s management company, Your Life Management Services (YLMS).
The HIU units were supplied customised to the requirements of each project, with isolation valves situated at the top of the unit ready for connection to the centralised plant heating network.
Matt Long continued:
“In addition to providing robust quality and efficient performance, the Uponor HIUs also offer excellent design values, a smart metal frame and top connections to avoid the need for additional pipework. This gives the Uponor HIU a great appearance and excellent customised performance.”
“The units’ hydraulic controls also simplify commissioning as there are no electronics to deal with.”
Andy Burns, construction manager at McCarthy & Stone added:
“We are always looking for new ways in which we can enhance comfort and safety for residents while managing costs and environmental impact. The HIUs provided by Uponor answer our requirements for a high quality specification while helping us to reduce operational costs by saving energy and providing a long-term, low maintenance solution.”
