Comprehensive drinking water and heating installation with the Roth pipe installation system
Dautphetal. Roth offers a pipe installation system for drinking water and heating installations with system solutions of up to 63 millimetres. This supports comprehensive installations from the water meter through to the extraction point and from the heat generator through to the manifold or radiator.
All components of Roth’s pipe installation system comply with the provisions of the German Drinking Water Ordinance and the German Federal Environment Agency’s white list, and can be used with all qualities of water without hesitation. They meet the hygiene-related requirements for drinking water systems. This is backed up by international approval, including from the ETA (Denmark), kiwa (Netherlands), OVGW (Austria) and DVGW (Germany).
Roth’s long-standing, tried-and-tested pipe installation system includes the multi-layer composite pipe Roth Alu-Laserplus and the Roth plastic fittings made of high-performance PPSU (polyphenylsulphone) supplemented with Roth metal fittings. All fittings have the integral Roth PressCheck for secure installation. Among other benefits, the perfectly matched components can be combined quickly and cost-effectively in a variety of ways to create connections above the floor, out of the wall or out of the skirting boards using one- or two-pipe systems. The range also includes the control stations for temperature precontrols and hydraulic components for underfloor heating manifolds.
Roth plastic fittings
Roth plastic fittings are made of polyphenylsulphone (PPSU). This high-performance plastic, which has been used for years in space applications, automotive engineering and medical technology, delivers excellent results in terms of tensile strength, elongation, rigidity, notched bar impact strength and heat deformation resistance. The Roth plastic fitting is corrosion- and incrustation-free, since no mineral deposits from water impurities can form on the smooth surface of PPSU.
The material offers outstanding pressure and temperature resistance and is suitable for long-term use in hot water systems. It exhibits excellent chemical resistance in the heating installation where inhibitors and anti-freeze are found, and when used with chlorinated drinking water. The slim-line, compact design of the fittings gives them maximum mechanical stability and makes installation easier, especially in tight spaces and when pipes are installed at an angle.
Roth offers a comprehensive range of fitting variants. Whatever the individual installation situation, T-connectors in various graded sizes are available for fast installation without the need for additional reducing elements.
The Roth PressCheck
The fittings are attached to the pipe using Roth radial press fitting technology. The familiar press pattern on Roth fittings can easily be seen and felt, giving the installer the opportunity to perform a quick visual and tactile check of the press fitting with Roth PressCheck for extra security. In compliance with DVGW Worksheet W534, the fittings with Roth PressCheck are designed to leak if they have not been pressed on: A defined volume of water will escape from an unpressed connection during testing, so an unpressed fitting can be detected immediately within the entire pipe system.
Roth Alu-Laserplus multi-layer composite pipes
The laser-welded aluminium pipe jacket of the five-layer Roth Alu-Laserplus multilayer composite pipe is made up of an alloy with significantly increased strength. With its homogenous structure, aluminium offers added safety and increased ease of installation. A thick-walled polyethylene core pipe with increased temperature resistance lies at the heart of the Alu-Laserplus system pipe. This greatly increases the stability of the overall pipe construction. The two adhesive polymer layers ensure a secure bond between the thick-walled core pipe, the homogenous aluminium layer and the outside polyethylene protective layer.
