REHAU Building Technology
District heating (heat networks) is the concept of one large centralised boiler instead of individual boilers. Heat is then transported via pre-insulated district heating pipes into each building. REHAU offer 2 pre-insulated pipes:
RAUVITHERM is the only PE-Xa district heating pipe manufactured in the UK which saves an estimated 29% on CO² emissions. Ideal for district heating, biomass, biogas and heat pump applications. Available in UNO 25-125mm and DUO 25-63mm.
RAUTHERMEX offers huge advantages over traditional steel pipework due to the speed and ease of installation. The high performance PU foam makes it ideal for large district heating over long distances where heat losses are critical. Available in UNO 25-160mm and DUO 20-75mm.

REHAU: RESPONSE TO SIXTH CARBON BUDGET
REHAU: RESPONSE TO SIXTH CARBON BUDGET
The Sixth Carbon Budget, required under the Climate Change Act, provides ministers with advice on the volume of greenhouse gases the UK can emit during the period 2033-2037. The Sixth Carbon Budget report is based on an extensive programme of analysis, consultation and consideration by the Committee on Climate Change and its staff, building on the evidence published last year concerning the UK’s progress toward Net Zero carbon emissions.
Comment from Steve Richmond, Head of Marketing and Technical for REHAU Building Solutions:
“The clouds are starting to part as we near the end of 2020 for many reasons, not least because of today’s announcement relating to the sixth carbon budget from the Committee on Climate Change (CCC) – particularly section two of the report, relating to buildings.
“REHAU most welcomes the specific focus on scaling up the market for heat pumps as a critical technology for decarbonising space heating, while maintaining quality. Additionally, expanding the rollout of low-carbon heat networks in heat dense areas like cities, using anchor loads such as hospitals and schools, is news to be celebrated.
“The roadmap of recommended dates demonstrate we need to move at pace. For example, all new build homes to have a heat pump or low carbon heat network and all new district heat connections to be low carbon by 2025. Heat pump sales must then be reaching 1m by 2030 with 5.5m heat pumps installed.
“We know these are viable technologies, but to see this advocated in black and white within the CCC’s official recommendations is exactly the sort of clarity we need. This follows the Government announcing its specific aim to install 600,000 heat pumps annually by 2028 last month, which was also a very encouraging sign.
“It is clear that the public and industry are behind moving towards zero carbon but there needs to be increased public awareness of how this can be achieved. One of the major challenges lies around skills, as the existing workforce may not possess all the skills necessary for operating low-carbon and low-flow temperature installations. It’s key that the Government now address these policy gaps and review what incentives may be needed to meet their green targets.
“Both sustainability and knowledge-sharing are driving forces within REHAU's own strategy, which is why we back these initiatives whole-heartedly. Our continuing professional development (CPD) programme has been a huge focus throughout this turbulent year, and is being revamped and expanded for 2021 with renewable technologies remaining at its heart. We believe this guidance is invaluable to the educational process.
“In summary, there can be little doubt that ambitious targets like net zero challenge industry to do more, and this report really does help visualise the practical steps to be taken.”
Rehau - Edinburgh hotel gets the silent (pipework) treatment
When tasked with installing the soil and wastesystem for a prestigious new hotel, contractors Emtec required a solution that would provide great acoustic performance and not disturb guests. Furthermore, the materials required to construct the prospective system needed to be readily and consistently available to meet the project's ambitious 8-month build time.
Part of a regeneration project in Edinburgh's New Fountainbridge district, the 262-room Moxy Hotel from Marriott International is situated on the former Scottish & Newcastle Fountain Brewery site, alongside offices, cafés, co-working spaces and a restaurant.
For any hotel, the visible furnishings and decoration be of the highest calibre for the guests' comfort. However, all aspects under the surface must also match these standards and offer best possible performance. To keep quality high and installation time to a minimum, Emtec chose polymer specialist REHAU to provide soil and wastepipework for the project.
Keep the noise down
Noise from a hotel's building services are expected to be minimal. To achieve this, the rooms were constructed offsite as prefabricated 'pods' with extensive soundproofing. These pods would then be installed, coupled at their connection points to the structure and service points.
To avoid any disturbance from water running through the system, the soil and wastesolution needed to offer excellent levels of acoustic performance. On top of this, it had to be adaptable enough to connect to the outlet of the prefabricated room unit. Faced with the challenge of finding a solution that could meet these demands, Emtec used REHAU's acoustic soil and wastesystem, RAUPIANO.
Ideal for multiple occupancy buildings like hotels, it combines sound-absorbing multi-layer technology, elbow joints with thicker walls, and patented acoustic brackets in a system with 17 dB sound rating, meaning vibrations or system noise do not disturb occupants. Not only did it match up to the building's acoustic requirements, but also helped tackle challenges posed by the offsite-manufactured rooms.
"RAUPIANO was not only a good choice because of its performance, but also because of how compatible it is with other pipework," said Andrew Currie, Project Manager at Emtec. "Sometimes with prefabricated units like these there can be lots of adaptations required, which uses more components and takes lots of time. The REHAU solution, by contrast, was able to be installed easily without giving us more work to make it fit."
With any development, there is pressure on contractors and developers to complete all works to tight deadlines. On a site with many different trades working in tandem, the quicker the installation is for each contractor, the more likely it is the project will be completed on time. As well as its easy connection to prefabricated units, the contractors were able to quickly install the rest of the system, avoiding any holdups that would let them miss the deadline.
"We had quite a quick turnaround for this project," added Currie. "RAUPIANO was very quick to install once you are familiar with it, so it helped to get the system in place quickly. Even the bracketing system was simple and fast to install, and because no extra tools were needed to fasten them, it made the entire process even quicker."
Another potential obstacle for many developers and contractors is the supply of materials. If resources are not available throughout the project, ensuing halted work could risk costly delays. With a tight deadline for completion, Emtec needed a ready supply of RAUPIANO pipework throughout.
"After we discussed with Emtec its requirements for the build, we made sure that there was enough RAUPIANO stock that we could earmark for the project," said Mark Taylor of REHAU. "Not only did we hold the stock for the job at our Manchester warehouse, we also made sure there was enough supply to a local merchant so it was available either the same day or next throughout the project."
Alongside its stock availability, REHAU's onsite training and attentive service throughout the project also impressed Emtec, and ensured installation time was minimised and delays avoided.
"The service from Mark and the team was great and we were able to get the team quickly up to speed installing the system," said Currie. "This, coupled with the ease and speed of installation and good supply of materials meant we were able to install the soil and waste pipeworkby within 6 months, well in time for the project's June 2020 completion date."
