The case studies listed here represent just a fragment of the work we (as Thermal Integration and previously as Dedicated Pressure Systems) have undertaken over the years, detailing the range of products we offer and the expertise we bring to the industry. Many of the contracts listed were designed and manufactured by us, and sold through our distributors. We have historically made branded products for Johnson & Starley (Heat Banks), Heatrae Sadia (Prefabricated Megaflo), as well as A.O.Smith (Flowstores).

Ancient History

It's difficult now to find case studies going back as far as the 70's. Some of the names and products that have formed our history include Utterly Ingham, Hydro Spartan, The Spartan ET50/100, The GR1 Valve (as on Tomorrow's World), DuoFlow Primatic Cylinders, Mainstream Thermal Stores, and Stowaway Heat Banks.

Old Thorlands Estate, Brixton

One of our first contracts for Heat Banks connected to heat networks, going back some 20 years, The original Stowaway Heat Bank delivers hot water to numerous blocks of flats on the Old Thorlands Estate for L.B.Lambeth, through United House.

L.B.Hillingdon

In 1998 we supplied 98 customised Heat Bank Xcel tank systems to L.B. Hillingdon, via Johnson & Starley, as one of four contracts supplied to the borough. The systems were designed to fit within a small void inside the bathrooms, hidden behind wall panels, and as such, the use of our vented Xcel system removed the need to annual access and servicing.

83 Pre-Fabricated Unvented Storage systems for Bellway homes, connecting to a centralised boiler plant. Systems were supplied fully pre-fabricated with unvented kits, central heating controls, and district heating controls, including heat meters and DP controls, for rapid installation.

Galliard Homes

Sites we have completed for Galliard Homes include Peckham Grove, Southampton Way, Marylebone, Bromley House, London Lane, Southwark Bridge, Harley House, Ashburton Gate, and Snakes Lane. Systems supplied include our Heat Bank Pandora systems, both Electric and Indirect, sometimes connecting to a central boiler plant, for the provision of high performance hot water and central heating, without discharge requirements or annual servicing.

Rydon Construction, St Giles Day Hospital

The site at St. Giles Day Hospital for 64 properties used the Pandora Electric Heat Bank to deliver high performance hot water. Other sites for Rydon included Devonport Street, and Durand Close.

Barratt Homes, Swiss Cottage

One of the many Barratt Homes developments we have supplied. Swiss Cottage makes use of 180 of our Pandora Heat Banks to deliver domestic hot water without a need for annual servicing or discharge pipes. Other sites included Ashmole School, Mare Street, and Hermitage Basin.

Bryant Homes, Melbourne House, Wallington

Our Heat Bank 2000 Electric Storage system was used to provide mains pressure hot water and central heating using Economy 10 electricity. Systems were sized to provide enough thermal storage to ensure all standard use was provided on cheap rate electricity, with minimal need to use boost supplies.

Megaflo System-Fit

In 1999 we approached Heatrae Sadia with a new product - a prefabricated Megaflo unvented cylinder. The product went on to become the well known Megaflo Systemfit. The controls package included a full Honeywell S-Plan Smartfit package, and made use of the new (at the time) Tectite push fit fittings to enable pipework to be rotated to match site connections.

Communal Heating System, 6 Flats

This contract from some time ago provides a good example of how we have a long history of communal heating system design, including equipment for the plant room and the HIUs in flats. We designed and supplied the entire system, including all the BMS controls, with a metering and billing system using Coster Controls that enabled contract-free management of the system. The technology has moved on, but the service is the same.

Network Housing

As part of a DECC funded project we were called upon to use our expertise in HIU design to analyse existing HIUs in London properties that have been poorly performing. The end result has been a dramatic improvement in efficiencies.

Initially, return temperatures to plant were seen to be only a few degrees below the flow temperature. The client needed to know why, and what could be done about it. Following site inspections, we were able to swap-out one of the guilty HIUs, taking it back to the factory where we were able to test out all sorts of possible improvements. The aim was to arrive at the best value for money approach to improve the performance of the other HIUs on the sites, short of simply replacing the HIU entirely. The end result was a combination of measures we could demonstrate to work as desired. We then managed the contracts on site to modify systems with the results that primary return temperatures dropped consistently as works went on. Once we had finished, the primary returns had dropped nearly twenty degrees.

HIU Standards

Not so much of a contract case study, as an example of how we rise to challenge - in this case proving to the industry just how efficient HIUs can really be. The new UK test regime for HIUs, funded by DECC and carried out at SP Swedish Technical Institute, put a number of the best know HIU manufacturers through rigorous testing in order to determine the efficiencies that would be seen in real world installations.

Needless to say, we aced the tests and demonstrated that average return temperatures below 25C are indeed achievable, when you know how. The next best HIU achieved return temperatures of 34C, with all others significantly higher.
