REHAU: The new sustainable universal pipe RAUTITAN flex green saves 90% CO2

Sustainable construction is not only becoming ever more important but is also increasingly becoming the norm. The new drinking water and heating pipe, RAUTITAN flex green can save more than 90% CO2 in the manufacturing process. It is based on renewable, bio-based raw materials and can help to achieve sustainability targets.

RAUTITAN flex green is a drinking water and heating pipe made of PE-Xa. What makes it special is that the plastic is made from renewable, biocircular raw materials. For example, vegetable fats are used, which are produced as waste and by-products in the food industry. External and independent certification by ISCC Plus ensures that the proportion of renewable raw materials can be tracked transparently along the value chain. ISCC Plus (International Sustainability & Carbon Certification) is a global certification program with the aim of establishing sustainable raw material chains.

The polyethylene used is mass-balanced and consists of 100% renewable, biocircular raw materials. This means that the production of RAUTITAN flex green saves more than 90% CO2 compared to standard fossil based PEX pipes on the market.

The new RAUTITAN flex green offers the same benefits as the tried and tested RAUTITAN flex:

Just as clean: The lead-free RAUTITAN flex green pipe system is hygienically optimised for drinking water installations. The smooth inner pipe walls and excellent impermeability of the cavity-free jointing technology effectively prevent contamination.
Just as flexible: RAUTITAN flex green is highly unlikely to buckle, especially in the case of small pipes. Despite this, the pipe is flexible: you can easily bend it over your thumb without any tools, even at low temperatures.
Just as reliable: RAUTITAN flex green achieves a permanently leak-tight connection with fittings and compression sleeves. The pipe itself is the sealant, with no O-rings and no manual labelling.

The pipe is made of high-performance PE-Xa plastic and contains a special oxygen diffusion barrier – making it suitable for both drinking water installations and heating. RAUTITAN flex green complies with DIN EN ISO 15875 and is oxygen-tight in accordance with DIN 4726. It can be used universally for drinking water and heating installations and is compatible with the REHAU RAUTITAN system of pipes, fittings, sliding sleeves and tools.

SANHA wall heating module demonstrates specific advantages

Wall heating systems are among the most efficient types of heat transfer. As surface heating, they are extremely well suited for combination with heat pumps, for example. In contrast to comparable systems, SANHA wall heating modules offer the advantage that they can provide heat both in the low temperature range and up to 60 °C. In addition, they are much easier to install. They are also much easier to install.

An old building in the south of Essen is currently being fitted with wall heating modules. This is an example of how our systems can demonstrate their advantages and support energy-efficient refurbishment at the highest level in a technology-neutral way.

The building, built in 1977, is currently undergoing a comprehensive energy refurbishment. This includes efficient façade insulation as well as a modern heating system based on natural gas condensing heating. A total of two floors with five rooms (one downstairs, four upstairs) are to be heated. The calculated heating load of the upper floor (85 m²) is around 2.5 kW (assuming 30 K to the outside temperature), which is optimally provided by wall heating modules, while the first floor is supplied with heat via underfloor heating.

The client opted for SANHA® wall heating modules primarily because of their high flexibility. The maximum heat output is up to 210 W/m², which is higher than comparable products. This means that wall heating modules can be operated very efficiently in the low temperature range during the transitional period and still use the high possible flow temperatures of the natural gas heating system on particularly cold days.

Another reason why the client chose SANHA® wall heating modules was the ease of installation: using a mounting rail and dowels, they are much easier to install than underfloor heating, for example; there is no need for labor-intensive ripping up of the floor and subsequent re-installation, drying times for the screed, etc. – a clear advantage.

Added to this was the fact that neither the wall heating modules nor the underfloor heating generate any convection or dust: “As an allergy sufferer, this aspect was very important to me,” says the client. The upper floor, which is particularly exposed to the sun on hot days, can also be cooled by the wall heating modules if necessary. This is particularly true for a studio with high ceilings.

Dew point undercutting and mold prevention

Wall heating also makes sense when it comes to preventing mold on the walls. Mold develops when water vapor from the air condenses on colder objects, i.e. when the temperature falls below the dew point (or dew point temperature). The type of ventilation also plays a role: it is better to ventilate several times a day than to keep the window tilted. Conventional convection heating systems cannot prevent moisture loss or condensation in every situation, as the warm air collects on the ceiling and sinks downwards after cooling – and can provide an ideal breeding ground for mold in the cooler areas of the wall.

@ Sanha

Wall heating works on the principle of the sun

Wall heating, on the other hand, does not primarily heat the air, but warms objects and people through heat radiation – similar to the sun. This is not only perceived as very pleasant, but also ensures lower humidity. In addition, this type of panel heating does not cause any draughts or swirling up of dust. Conventional radiators, on the other hand, lead to the air movement described above, which is caused by layers of different temperatures. For ideal protection against mold growth, operation at a minimum temperature of 16 °C is advisable (climatic conditions in Central Europe; the dew point can shift under very cold or very dry climatic conditions).

Room heating and cooling

With the wall heating module, SANHA® provides a system for room heating and cooling (room heating) that is characterized in particular by exceptional living comfort, very simple installation, significantly better energy efficiency due to a lower average room temperature and particularly health-friendly properties. This system is ideal for both new buildings and the renovation of existing buildings.

Wall heating modules are supplied ready to use with a surface that can be painted or wallpapered directly. The SANHA® wall heating module is a prefabricated element that is installed in a similar way to a panel radiator. It consists of a galvanized sheet steel frame in which a multi-layer composite pipe (PE-RT/AL/PE-RT) is inserted and enclosed with a special heating mortar. The element is encased in cardboard paper. The maximum heat output is up to 210 W/m², which is higher than comparable products.

Notes on storage and transportation

The SANHA® wall heating modules must be treated similarly to drywall panels on the construction site, i.e. protected from moisture in particular. The modules must not be placed on the connecting pipes. The modules are delivered on pallets. When transporting individual modules, bending must be avoided. They must therefore be transported on edge. There is a banderole with corresponding instructions on each module. This label must be removed during assembly.

KWD Market+Charts Report: Impact of declining housing completions

At its summer conference in June, Euroconstruct published the latest projections for housing completions. These are now significantly lower than expected at last winter conference in 2022.

The headline of the official Euroconstruct report of the summer conference in June of this year already suggests a falling housing construction forecast: ” Risks and uncertainties impeding the growth of the European construction market”. Even clearer is the headline of the press release of the German ifo Institute related to the situation in Germany: “Significantly fewer new homes by 2025”!

Already at the beginning of the year, when preparing the current KWD Market + Charts study with the forecast for pipe consumption for surface heating, radiator connection and sanitary installation, we considered a worsening of the construction completion figures as a possibility. So, we have again included the Crisis Calculator to our market report.

The Crisis Calculator is intended to provide a way to respond to increased construction interest rates, high realization costs and economic slowdown in the new construction market. With its help, every user of our market study can react individually to changes by adjusting the forecasts for 2024 and 2025 by means of a percentage input per country.

For the current situation in Germany, the crisis calculator can show the new residential construction situation as follows:

The KWD Market +Charts study is based on the forecast from the ifo Institute from Nov. 2022. However, as can be seen in the table on the right, the expected housing completions in Germany shrink drastically in the new forecast: 30% in 2024 and almost 40% in 2025.

However, it must also be seen

7hat subsidies for modernization projects have been raised sharply and that the modernization market should therefore grow.
and also in the new construction sector, the heat pump and thus frequently surface heating systems will play a much stronger role.

We will now simply assume a possible decline of 15% in pipe consumption in 2024 and 2025 in Germany as an example. The situation would then be as follows:

The report KWD Market + Charts “Heating & Plumbing Pipes Europe 2023” estimates how many million meters of pipe have been or will be installed in domestic plumbing systems in Europe and lists them by pipe material and application per EC19 country.

The KWD report costs 1,200 euros for our subscribers and 1,450 euros for all others (in Germany plus VAT, abroad with advance payment). Authors are Jutta Hix, chief editor of the KWD information services and Achim Seydel of Seydel Consulting.

Jansen expands production capacity and focuses on sustainable energy generation

Jansen expands production capacity and focuses on sustainable energy generation

Jansen Plastics offers a wide range of extruded plastic solutions characterised by Swiss quality, reliability, safety and economy. These are used in the areas of water management, building services, geothermal energy and specific customer profiles. Jansen has long-standing expertise in multi-layer and multi-component extrusion. Now the possibilities for producing composite pipes for a wide range of applications are being expanded.

Major investment in innovative multi-layer pipe production plant

As the most innovative supplier of technically sophisticated composite pipe solutions, Jansen is investing the impressive sum of around CHF 5.0 million in the most modern, interlinked multi-layer pipe production plant. The new plant has an annual capacity of over 17 million metres. The integrated laser welding system no longer requires welding electrodes; as a result, the heat impact on the material is lower and butt welding is more reliable.

In addition to the technical advantages, a local partner was chosen in order to lend holistic weight to the issue of sustainability. The composite pipe system opens up new production possibilities in the field of geothermal energy for the JANSEN hipress geothermal probe, the strongest geothermal probe in the world, and the PRIMA pipe range for the high-temperature range with drinking water approval. This also includes the PE-RT aluminium composite pipe made of temperature-resistant polyethylene with an aluminium layer.

Sustainability: major investment in solar energy

In March, the contract for the construction of a new 2.1 MWp photovoltaic plant was awarded; it is one of the largest plants in the region of Eastern Switzerland. Back in 2009, the largest PV system in the region at the time was installed on one of the production halls. In 2022, another followed with an output of 608 kWp. In the next few years, more roofs are to be covered with PV modules.

With these investments, Jansen is promoting its sustainable development with the future aim of increasingly producing the necessary energy for its production operations itself, or to be as energy self-sufficient as possible in the future.

KWD market report: How are Europe’s pipe markets developing in times of crisis?

Answers and forecasts in the new update of the KWD Market + Charts “Heating & Plumbing Pipes Europe 2023”. It shows the consumption of pipes for domestic installations in Europe by materials and application per country! NOW with Long Time Charts for the TOP 5 countries!

The consumption of pipes in hot and cold water installations is of course firmly linked to the building construction activity, both new construction and modernization, in the individual European countries. Therefore, a basis is also the Euroconstruct study, which represents 15 Western European and 4 Eastern European countries in terms of construction volume.

Ludwig Dorffmeister from the ifo Institute in Munich, which is the German member of Euroconstruct, recently gave a summary of building construction activity in the coming years based results of the latest Euroconstruction Conference at November 2022.

Nearly all factors negative as European construction looks set to stagnate: Following strong growth in 2021 and 2022 (+ 5.8 percent and + 3.0 percent), the European construction sector is likely to be spared another downturn. This year and next, the market will stagnate, and in 2025 it will grow only slowly at just over one percent. The stimulus factors here include government modernization aid in building construction, in some cases considerable investment requirements in the housing and infrastructure sectors, and the much more positive economic outlook again from 2024. “The European construction sector is benefiting in particular from rising construction demand in France, Spain and the UK. Growth rates there are between two and a half and just under seven percent.” explains Ludwig Dorffmeister. In Germany, a significant decline in new residential construction is expected, but the large construction backlog and long project implementation times will stabilize the new construction market for the time being.

The now published report KWD Market + Charts “Heating & Plumbing Pipes Europe 2023” estimates how many millions of meters of pipe have been or will be installed in domestic installations in Europe and lists them by pipe material and application area per EC19 country.

The following pipe materials are analyzed in the application areas of underfloor/surface heating, radiator connection and sanitary installation:

Metal pipes: steel / copper / stainless steel
Plastic pipes: PEX / PE-RT / PP-R / PB
Multilayer composite pipes: PEX or PE-RT – Aluminum – PEX or PE-RT

New this year are Long Time Charts. It shows the long-term development over 20 years, i.e. from 2006 to 2025 for Europe and the 5 strongest pipe countries: Germany, France, Great Britain, Italy and Poland.
