Status - Installed / Early Operational Phase
A multi-building student accommodation project delivered in partnership with Hydrocert and CBRE, replacing underperforming legacy magnetic conditioning systems with Integro™ technology to support whole-building limescale control, hot water reliability, plant protection and reduced maintenance across high-occupancy residential buildings.
“Supporting resilient hot water performance and reduced scale-related maintenance across student accommodation assets.”
As part of the Οκτώβριος installation works, the legacy magnetic systems were removed and the Integro™ units were installed in their place, using the existing treatment positions wherever appropriate. This allowed the project to make use of established plant room locations, isolation points and electrical supplies, while upgrading the buildings to a more robust long-term scale-control strategy.
This was an important part of the project. Magnetic devices can be effective in certain limited and localised applications, particularly where flow conditions and treatment objectives are tightly controlled. However, high-occupancy student accommodation buildings present a more demanding whole-building challenge, with cold water storage, booster sets, calorifiers, hot water return loops and continuous domestic water demand.
For these applications, Integro™ was selected as the replacement technology due to its suitability for larger building applications, its long-lasting non-consumable operating principle, and its ability to treat full domestic water supplies and targeted hot water return circuits.
Επισκόπηση
The Yugo Student Accommodation Bristol project represents a multi-building deployment of Integro™ technology across high-occupancy student accommodation assets in Bristol.
The programme has been delivered by Sidon Water in partnership with Hydrocert, with CBRE acting as the facilities management provider. Hydrocert commissioned the initial surveys on behalf of CBRE to assess ongoing limescale issues and identify suitable Integro™ installation points across key domestic water systems.
The surveyed and treated buildings include:
- Yugo The Courtrooms
- Yugo Print Hall – Building A
- Yugo Print Hall – Building B
The technical surveys were completed in Ιούλιος 2025, and the Integro™ systems were installed in Οκτώβριος 2025.
Across the buildings, the sites were experiencing persistent limescale accumulation affecting both hot and cold water systems. Existing magnetic or electromagnetic conditioning equipment had already been installed in the plant rooms, but the buildings were still experiencing scale-related operational issues.

Χρονοδιάγραμμα & Λεπτομέρειες έργου
Phase 1 – Multi-Building Site Survey
Sidon Water attended the Yugo Bristol accommodation sites in Ιούλιος 2025 to assess the existing water systems, review limescale challenges and identify suitable Integro™ installation points.
The surveys considered:
- Συστήματα αποθήκευσης κρύου νερού και αντλιών ενίσχυσης πίεσης
- Existing magnetic and electromagnetic conditioning equipment
- Incoming cold water pipework sizes and available installation space
- Hot water generation plant
- Calorifier arrangements
- Hot water return loops
- Access, isolation and electrical supply
- Practical installation constraints
- Opportunities for phased deployment across multiple buildings
The surveys confirmed that each building had specific plant room layouts and installation considerations, but all shared the same core operational challenge: persistent limescale accumulation across domestic water systems despite legacy magnetic conditioning equipment already being in place.
Phase 2 – Οκτώβριος 2025 Installation
Following the Ιούλιος surveys, Integro™ systems were installed across the Yugo Bristol sites in Οκτώβριος 2025.
During the installation works, the existing magnetic conditioning systems were removed and Integro™ units were installed in the same treatment positions where practical. This provided a direct upgrade path from localised magnetic conditioning to a more comprehensive Integro™ solution.
The installation strategy focused on two key areas:
- Whole-building cold water treatment
- Targeted hot water return loop protection
This approach was designed to treat incoming water supplies while also directly protecting hot water generation plant, calorifiers and recirculation systems.
Phase 3 – Building-Specific Installation Strategy
Yugo The Courtrooms
Yugo The Courtrooms was experiencing limescale issues across the building’s water system. The plant setup includes cold water storage tanks, a booster pump set and hot water generation via Andrews water heaters, fed by boilers and CHP.
The cold water main enters the plantroom and feeds a pair of cold water storage tanks via DN100 pipework. Water then exits the tanks through a booster pump set and continues into vertical DN100 pipework. A clear and accessible position was identified between two isolation valves.
An Integro™ 4 was selected for the DN100 cold water supply to treat the full cold water supply to the building.
The hot water system includes two Andrews water heaters served by a single hot water return line. Although the pipework around the calorifiers is slightly congested, a suitable vertical section of return pipework was identified, with isolation already present above and below.
An Integro™ 2 was selected for the hot water return loop to reduce limescale within the water heaters, lower maintenance demand and support energy performance.
Yugo Print Hall – Building A
Yugo Print Hall Building A was experiencing persistent limescale issues throughout both hot and cold water systems. An existing magnetic water conditioner was installed, but the site continued to experience scale-related issues.
The cold water main enters the building and splits to feed two main cold water storage tanks. The existing conditioning system was installed between two isolation valves spaced approximately 1.6 metres apart, with an electrical supply already available.
As part of the Οκτώβριος installation, the existing magnetic system was removed and replaced with an Integro™ 4. This treats all cold water entering the building and provides incidental benefit to the hot water system, including the preheat calorifier.
The hot water system includes three calorifiers. The first acts as a preheat unit, is fed only with cold water and is heated via an air source heat pump. The second and third calorifiers are fed from the preheat unit and are additionally heated via the hot water return loop.
The site was also experiencing issues with immersion elements, which were not operational, and descaling of the calorifiers had been planned due to ongoing limescale accumulation.
An Integro™ 2, or Integro™ Eco where appropriate, was selected for the 38mm hot water return loop. This directly protects the calorifiers, helps prevent further scale build-up, supports operating temperatures, reduces maintenance and lowers energy consumption.
A secondary cold water supply also feeds two CAT 5 tanks.
Yugo Print Hall – Building B
Yugo Print Hall Building B was also experiencing ongoing limescale accumulation across hot and cold water systems. A legacy magnetic conditioning system was installed, but the ongoing scale issues indicated that it was not delivering the level of whole-building protection required for this application.
The cold water main feeds directly into the cold water storage tanks. The outlet from the tanks passes through a booster pump set, then into 3” copper pipework before reaching a pressure reducing valve. The water then passed through the existing magnetic unit, which appeared to slightly reduce the pipe diameter.
There was approximately 900–960mm of available linear installation space. Although an Integro™ 4 would typically be considered for this type of application, the space constraints meant an Integro™ 3 was selected. The control unit was configured to deliver a higher energy output to support effective treatment.
As part of the Οκτώβριος installation, the existing magnetic unit was removed and the Integro™ system was installed in its place.
The building has three calorifiers in operation, with immersion elements disconnected or inactive at the time of survey. A single return pump serves all three calorifiers.
An Integro™ 2 was selected for the hot water return line serving the calorifiers, providing direct protection to the hot water circuit and supporting reduced scale accumulation within the calorifier system.

Installed System Strategy
The installed strategy provides a whole-building approach across the Yugo Bristol accommodation buildings.
Cold Water Treatment
Cold water treatment was prioritised because it provides whole-building coverage and supports both cold water distribution and downstream hot water generation.
Installed cold water strategy:
- The Courtrooms: Integro™ 4 on DN100 cold water supply
- Print Hall Building A: Integro™ 4 replacing the existing magnetic conditioning system
- Print Hall Building B: Integro™ 3 with boosted control output due to space constraints, replacing the existing localised magnetic unit
Hot Water Return Treatment
Hot water return treatment provides direct protection for calorifiers, water heaters and associated return pipework.
Installed hot water strategy:
- The Courtrooms: Integro™ 2 on the hot water return loop
- Print Hall Building A: Integro™ 2 or Integro™ Eco on the 38mm hot water return loop
- Print Hall Building B: Integro™ 2 on the hot water return line serving the three calorifiers
Programme Value
The Yugo Bristol programme is a strong example of how Integro™ can be applied across a student accommodation portfolio where legacy localised conditioning systems had not delivered the level of scale control required for long-term building performance.
