Despite the high quality of drinking water in the Nordic countries, the condition of the old pipe networks poses challenges. For example, Tin Finland most of the network was built between 1960 and 1990 and in the biggest cities parts of the network are over 100 years old. According to a recent study in Finland (ROTI 2019), 12% of the sewer network and 12% of the potable water network has deteriorated and there is an increasing need to renovate the old networks to both ensure water quality and minimise water losses. In Finland, 68 million m3 of mains water is lost every year and a substantial part of this is due to leakages (SYKE 2018). In Sweden, the total leakage of clean drinking water is about 15% on average, corresponding to 99 million m3 (Svenskt Vatten 2019). This is not only a waste of clean drinking water – resources used to collect, treat and pump the drinking water are also wasted. Losses of water, and in issue 2/2019 particular leakages, are relevant for distribution network efficiency in all European countries. New innovations are needed to help solve these challenges. On p. 12, you can read about how our new Water Monitoring Services are helping the city of Pori in Finland to monitor 4 In Brief 16 Industrial its leakages.

  • National Museum of the United States Army
    National Museum of the United States Army na.rehau.com/projects Army museum enlists REHAU radiant system for climate control After more than 240 years of honorably serving the country, the U.S. Army is getting its own museum. Sited on a hilltop at Fort Belvoir in northern Virginia, the museum will occupy more than 80 acres of grounds and feature 185,000 ft² (17,187 m²) of exhibition and support space. Museum visitors will enter through a spacious lobby with a 35-ft (10.7-m) ceiling that features representations of the Army’s history. An engraved Honor Wall at the southern end of the lobby commemorates each of the battles fought in the Army’s history. The lobby leads to a vast, open exhibit hall – “Essentially, an airport hangar,” said Jason Calcagno, project manager during the museum’s construction for Southland Industries, the design- build company that served as the mechanical engineer for the project. Temperature control for the exhibit hall and the lobby is provided, in part, by a REHAU radiant heating and cooling system. Calcagno explains that this technology is ideal for this application, because the environment is controlled near the ground for visitor comfort, while energy is conserved by reducing the heating and cooling requirement in the air space higher up. A dedicated outdoor air system (DOAS) provides ventilation and humidity control. Combining radiant and DOAS for space conditioning significantly reduces the amount of HVAC energy, which in REHAU’s experience has been as much as 35 percent when compared to a standard forced-air system.

  • UNDERFLOOR HEATING SYSTEMS Guidance Notes 02
    WARM WATER UNDERFLOOR HEATING SYSTEMS Guidance Notes 02 WARM WATER UNDERFLOOR HEATING SYSTEMS Introduction Underfloor heating systems consist of a series of pipes which are integrated into the floor structure and conduct heat to the surface of the floor. The heating pipe is the main component of the system. By using flexible pipes joined to a central manifold, continuous lengths can be installed within the floor structure without jointing. Underfloor heating systems provide an attractive alternative to radiators and other convective heating systems. They can easily be used in all types of modern floor construction. Underfloor heating is widely used in mainland Europe. In the UK, it is frequently used in commercial situations and luxury homes. Its benefits are increasingly accepted in housing developments and self-build applications. Benefits Underfloor heating creates an even surface temperature across the entire floor area within the building. Using the floor as the heating element frees wall and floor space for furniture, decorations and other uses. However, in utility rooms and bathrooms where radiators may be desirable (for airing clothes, etc.), they can be incorporated into the system and used in conjunction with the underfloor heating. Underfloor heating systems are safe and clean. As the floor is large in comparison with a normal wall mounted radiator, the system requires a much lower water temperature to achieve the same room temperature, eliminating the risk of burns and improving operating efficiencies. It reduces wasted heat at levels above head height which reduces running costs. As the systems generally operate with a flow temperature between 40°C to 50°C, the use of a condensing boiler can deliver efficiencies of up to 98%.
