Introduction

Continuously operated recirculated systems, also known as secondary hot water circulation or ring main systems, are an essential component in modern plumbing. These systems ensure that hot water is readily available throughout a building while promoting better hygiene. In this guide, we’ll explore how these systems work, where they are commonly used, and why they are a valuable addition to any plumbing skillset.

Applications of Continuously Operated Recirculated Systems

These systems are particularly popular in large sanitary environments such as healthcare facilities and hospitality settings. Their design significantly reduces the risk of bacterial growth in the pipes, ensuring a hygienic water supply. This makes them indispensable in settings where the cleanliness of the water is paramount.

How Do They Work?

Continuously operated recirculated systems use a pump to circulate hot water through the pipework continuously. This constant flow prevents stagnation and maintains high water temperatures, which inhibits bacterial growth. By reducing opportunities for bacteria to thrive, these systems also lower the risk of Legionnaire’s disease.

Understanding Legionnaire’s Disease

Legionnaire’s disease is a severe form of pneumonia caused by the Legionella pneumophila bacteria, often found in stagnant water. The disease can be life-threatening and is contracted by inhaling water droplets containing the bacteria. Continuously operated recirculated systems combat this by maintaining a water temperature of at least 60°C, which prevents the bacteria from forming.

Ensuring Hot Water Quality

Unlike other hot water systems, continuously operated recirculating systems are easier to disinfect. Two main approaches can be employed:

  1. Thermal Disinfection: Designed to withstand temperatures up to 70°C, the system can be disinfected by heating the water to this temperature and rinsing each tap or sampling point for at least three minutes.
  2. Component Quality: Using high-quality components like the PE-Xc multilayer pipes ensures exceptional performance and longevity.

The Role of Tigris K5

Tigris K5 is a multi-layer composite pipe designed for potable water and heating applications. It offers several advantages over traditional copper piping, such as:

  • Five-layer construction: Includes an inner layer of cross-linked polyethylene, an outer layer of HDPE, and an aluminum layer in between.
  • Oxygen diffusion resistance: Prevents oxygen from entering the water system, reducing the risk of corrosion.
  • Thermal expansion comparable to copper: Ensures stability in varying temperatures.
  • Flexibility and fewer fittings: Speeds up installation and lowers material costs.

Unique Features of Tigris K5

  • Acoustic Leak Alert: Emits a loud whistle to identify any unpressed fittings.
  • Opti Flow: Enhanced inner bore improves flow performance.
  • Multi Jaw: Can be pressed with all common profiles.
  • Easy Fit: Allows for easy pipe insertion without calibration.
  • In4SureTM: Provides clear visual cues for unpressed sleeves.
  • Ultra Seal: Offers reliable O-ring sealing, tested beyond market standards.
  • Pipe Grip: Ensures pipes stay in position before pressing.

Providing Hygienic Water Supplies Across the UK

Traditional hot water systems can foster bacterial growth due to stagnant water. Continuously operated recirculated systems maintain water temperatures above 60°C and ensure constant water movement, significantly reducing this risk. They also guarantee consistent water pressure and availability, making them a superior choice for maintaining a hygienic water supply.

Catering for the over forty-five age group, Sandy Oaks is one such residential park. Situated in 35 acres of picturesque woodland, in an idyllic rural setting, close to Sherwood Forest, it boasts 149 individual homes, all with their own garden and driveway.

Due to the topography of the park, a retaining wall solution was required 2.5 meters high that would protect the homes and gardens from landslips and the egress of land.

The retaining wall not only needed to be strong & secure but also had to fit in aesthetically with the surrounding countryside and architecture. The answer? Elite Precast Concrete’s Retainer-Rock® modular walling system.

After discussing the different retaining walling options with Paul Cartwright, from Elite Precast Concrete, the contractor decided to go with Elite’s new walling system, Retainer-Rock®.

The Retainer-Rock® walling system answered both his and the client’s need for an off-the-shelf walling product that was available within days of ordering and was easy to install, even when using it for the first time and despite the adverse weather, the client built three walls within days. Most importantly though it blended well into the appearance of the residential park.

With two face finishes currently available (Cobblestone and Liscio Stone), Retainer-Rock® is a secure and low maintenance retaining wall solution that will continue to look good as it weathers.

Visit the Dales Fabrications website

Dales supplies Solar Shading Solutions for Solihull Retirement Village:

Dales Fabrications supplied their Aluminium Shadex 150 Solar Shading, finished in PWF1 Timber Effect for Solihull Retirement Homes.

Whilst enhancing the architectural appeal of the project, integrating this system into the design also ensured that the buildings would effectively manage solar heat gain from day one, allowing more comfortable living conditions for residents and improving energy efficiency. Moreover, their installation aligns with the guidelines set out by the Part O regulations introduced in June 2022.

The timber effect finish from Dales made it possible to achieve the appearance of timber without the fire risk or risk of algae, warp, deviation and regular turning traditionally associated with timber blades.

Dales also supplied aluminium balcony cladding with self-draining soffits, privacy screens, and ‘window-frame’ cladding for the project.

The £47m retirement village in partnership with the ExtraCare Charitable Trust accommodates over 300 homes for over 55’s and was designed by DLA Architecture.

The need for action:

As we head into summer, many of us will be enjoying the warmer, longer days. However, for several residents in the UK, the increased solar gain and excessive heat create uncomfortable living conditions and may even pose serious health risks.

Whilst the conversation in the UK has typically centred around reducing heating costs and increasing insulation in homes, MPs are increasingly expressing concern and urging immediate government action to protect tenants from the adverse effects of overheating, which can cause health issues such as heat exhaustion and dehydration. Furthermore, there is an urgent call to reduce the need for air conditioning, with The Intergovernmental Panel on Climate Change suggesting that by 2050, the average number of days a year Europe will require air conditioning will have risen by 30%.

Additionally, this June marks the second anniversary of the implementation of the new part O regulations, which aim to ensure that new residential buildings are designed to minimise overheating and therefore protect occupants’ welfare. The regulations promote sustainable building practices by emphasising energy efficiency and passive cooling techniques. They apply specifically to new residential buildings, including dwellings, common areas of flat blocks, care homes, and halls of residence.  Developers, architects, and builders must all comply.

Solar shading as a solution:

The Building Research Establishment suggests that the installation of external solar shading systems is one of the most cost-effective and least adverse methods of reducing solar gain and therefore, emissions of carbon dioxide during building use. Research indicates that a well-designed solar shading system can pay for itself through energy cost savings within five years.

Solar shades are designed to reflect the sun’s rays, significantly reducing solar heat gain. Aluminium solar shades in particular are a great option as they are durable, weather-resistant, and require minimal maintenance. This makes them an efficient long-term investment for providing an effective, stylish, and durable solution to keeping accommodation cool and comfortable, whilst meeting the requirements of Part O regulations.

Dales Fabrications design and manufacture an extensive range of standard and bespoke aluminium solar shading solutions. Additionally, Dales can advise on the size of the necessary projection and different methods of support available for the different shading types. More details are available at https://www.dales-eaves.co.uk/solar-shading/.

CPDs:

In addition to their product offerings, Dales can also provide in-practice CPD seminars that cover content about Solar Shading systems:

–          Solar Shading: Form, Function and Fire Safety with Part O Update

–          Solar Shading Systems: Compliance with Part O, Part L, and Part B

–          Solar Shading: Form, Function, Fire Safety & the Scottish Building Regulations

–          Solar Shading Systems: Compliance with Scottish Building Regulations

Dales’ CPD seminar ‘Solar Shading Systems: Compliance with Part L: Conservation of Energy and Part B: Fire Safety’ was spotlighted in May’s RIBA CPD Showcase, in the Sustainable Architecture category.

Technical Drawings – MS Fire Type C Drained Protection – Delta Membranes

Delta Fire Retardant, Type C Waterproofing – Delta Membranes

Comparison Test of Delta MS 500 Fire – Delta Membranes

Fire retardants serve a crucial role in fire safety measures, fire retardant materials possess the unique characteristic to slow down or even halt the spread of fire. This key feature makes them an essential element in fire safety management.

Typically, the concepts of water management and fire safety are not concurrently considered due to their contrasting nature and effects.  Though it may initially appear far-fetched, upon closer inspection, it is not as irrational as it may first seem.

Waterproofing refers to the technique of preventing water from penetrating a structure and controlling the flow of water and water vapor within and out of the structure.  Type C waterproofing integrates two key elements for optimal functionality: Cavity Drainage Membranes and Basement Drainage Systems. These components work in unison to ensure efficient water management in structures.

Type C Cavity Drainage Membranes tend to be crafted from High-Density Polyethylene (HDPE); a tough, durable plastic material known for its high strength-to-density ratio. This material offers excellent resistance to impact, moisture, and chemicals, ensuring long-lasting performance and reliability.  However, polyethylene possesses flammable characteristics.  It can easily catch fire under certain conditions, due to its chemical composition.  When exposed to certain conditions, plastic can undergo a transformation where it starts to melt and subsequently produce droplets. This occurrence is crucial to consider when dealing with plastic materials.

The Euro class system is an analytical tool that evaluates various fire-related characteristics. These include ignitability, the rate at which flames spread, heat emission, smoke generation, and the likelihood of producing flaming droplets or particles.  Products achieving A1 and A2 classification are defined as non-combustible under Regulations.

The Euro class system is designed to unify standards throughout the European Union. It systematically classifies products into seven distinct fire reaction classes, from A1 to F, with F being the most combustible. This classification is determined through a specific test or a combination of tests. This professional framework ensures a consistent approach to product safety standards.

The system offers an extended classification, usually linked to fire response classes D through B. This classification relates to smoke production, ranging from s1, indicating minimal or no smoke, to s3, which signifies considerable smoke. It also categorises flaming droplets or particles, from d0 representing no presence, to d2 signifying a significant amount.  This information is crucial in understanding the behaviour and potential hazards of fires.

Delta MS 500 Fire Retardant is a robust Type C, Cavity Drained Protection system, designed to withstand demanding conditions. It holds a Euroclass fire rating of B-S2, d0 (EN 13501-1:2018), an indication of its superior fire resistance.  Delta MS 500 Fire Retardant does not compromise on its strength, durability, functionality, or workability. This makes it an excellent choice for applications where both fire safety and structural integrity are paramount.

The Delta MS 500 Fire Retardant is a product that carries the BBA certification. This seal of approval signifies that this fire-retardant waterproofing system meets the rigorous standards set by the British Board of Agrément. The certification is an assurance of quality, reliability, and safety in fire retardation.

Flame retardants play a critical role in enhancing safety measures in homes or buildings. Their primary function is to delay the spread of fire, thereby providing occupants with crucial extra time to evacuate and firefighters with additional time to intervene. Moreover, they contribute significantly to preventing property damage, not only from the fire itself, but also from potential water damage arising from automated sprinklers or fire control efforts by local authorities.

MEETING PLANNING DEMANDS WITH NEW LINCOLN CLAY PANTILE

Building Products Index Ltd Roof tiles Leave a Comment

View the Marley entry on BPindex

Visit the Marley website

Marley’s new and improved Lincoln Clay Interlocking Pantile, with an s-curve profile and thin leading edge, has recently been specified on a new residential property development in Gainsborough, Lincolnshire.

Located in a conservation area, the home, designed and constructed by My Home Developments, had to meet a number of stringent planning requirements. This included the stipulation that only a clay pantile could be selected for the roofscape.

“When it came to selecting the right tile for the roof, we obviously needed to meet planning requirements, but we also wanted to create a beautiful aesthetic that matched the modern design of the home we envisioned,” explains Tom Crowe, founder, My Home Developments.

“Many of the village’s surrounding properties have traditional, plain clay pantiles on the roof, which look great, but can be limited in colour options. We were looking to create a softer, sleeker appearance, so the roof could blend seamlessly with the rest of the new building’s aesthetic. Marley’s new Lincoln clay pantiles enabled us to achieve exactly that, while still meeting planning requirements.”

Marley’s new Lincoln Clay Interlocking Pantile range is available in single coloured Red Smooth, and Rustic Red, which incorporates a flash of dusting to create a more weathered appearance and enhanced kerb-side appeal. Changes have also been made to the texture of the pantile, so it now offers a marked heritage aesthetic, which ensures greater design choice for specifiers such as Tom.

“Creating new builds in well-established locations means we have to be mindful of blending in and collaborate with the planners to ensure we add to the area’s appeal,” explains Tom. “We opted for the Lincoln in the Red Smooth to achieve exactly this, which has provided a really attractive roof that enhances the modern style we were seeking, while still being in-keeping with the other homes in the area.”

Merchant support

Tom worked with one of the UK’s leading builders’ merchants, Jewson, in Lincoln, to discuss the project and source the best roofing tile to meet his needs. He was made aware that Marley had recently relaunched its Lincoln clay pantile range, with improvements to the colourway and texture. And after seeing a number of photographs of the new product, decided it would be ideal.

 

 

 

 

 

 

 

Ian Milson, Building and Roofing Sales Specialist at Jewson in Lincoln, says: “We’ve worked with Marley for many years, and we had full confidence the new Lincoln would deliver the quality finish Tom was looking for. When it comes to our relationship with our customers, it’s important that we’re able to offer new and innovative products that help get projects completed in the best possible way. Marley’s products enable us to do exactly that. They’re pivotal to all our clients’ roofing projects in the area.”

 

 

 

 

 

 

Cadell Beasley, Area Specification Manager at Marley, says: “The new Lincoln delivers a sleek aesthetic and modern appearance, while still carrying the traditional feel of a heritage clay pantile roof. We’ve worked with important suppliers, such as Jewson, to promote the advantages of the new Lincoln, and it’s great to see it now being specified on projects such as the residential development in Gainsborough.”

Production for the new Lincoln has also moved to Keele in Staffordshire, with the clay used for its manufacture now sourced from nearby quarries. This makes Marley one of the only providers of a British-made clay pantile.

 

 

 

 

 

 

 

“The decision to transition our production to the UK will deliver environmental benefits too, through a reduction in shipping and transport requirements, and subsequent reductions in associated carbon emissions,” continues Cadell. “It will also provide additional versatility and assurance of product supply for the UK roofing sector.”

Speaking about the end result, Tom concludes: “The relaunch of the new Lincoln was perfectly timed for our development project. The clay pantile not only looks good, but it was also easy to install. The fact that it’s manufactured in the UK is another plus point for us.

“The finished roofscape adheres perfectly to the wishes of the local planners, allows the property to sit seamlessly alongside the neighbouring houses and is a great example of the natural beauty that clay pantiles are renowned for.”
