Installation of Rehau plumbing and underfloor heating verticals

03 December 2008 - Comments (1)

Construction

Plumbing and heating installations are progressing very well in Amadeo. After digging walls and slabs for the installation of cabinets and verticals, Kombo started the proper installation. All piping work has been done in bathrooms and kitchens in Amadeo-A2 and verticals for underfloor heating and fancoil are being installed.

Water, wastewater and electric installations will all be passed in the floor, in a layer of light concrete. On top, insulation will be placed and then underfloor heating.

Installation of the plumbing system

All bathrooms in Amadeo-A2 have been equipped with the water and wastewater pipping for shower, sink, washing machine, central evacuation and toilet.

Each bathroom is equipped with a cabinet in the wall that holds the hot and cold water distribution system. There are 3 Rehau manifolds in the cabinet. 1 for cold water distribution, 1 for hot water distribution and 1 for hot water recirculation. That last one allows to have hot water almost immediately on the tap.

All water and heating distribution is done with Rehau RAUTITAN Flex pipes. Each pipe is completely insulated with Armacell Armaflex AC. Armaflex AC is a flexible elastomeric insulation material with built-in water vapour barrier and a closed cell structure that provides excellent thermal insulation and protection against condensation.

Beside bathrooms, kitchen are being equipped for the kitchen sink and dishwasher.

Installation of underfloor heating verticals

The work on the heating system also progressed well. Cabinets, holding the underfloor heating manifolds, have been installed in all apartments and verticals are being done. Like the water distribution system, verticals are done using Rehau RAUTITAN Flex universal pipe, insulated with Armacell Armaflex AC.

There are 4 verticals for the complete system. 2 for water circulation in the underfloor heating/cooling system and 2 for water circulation in the additional fancoil system.

Installation of solar collectors verticals

In Amadeo-A1, Kombo started to pass verticals for connecting solar collectors. Because of the potentially high temperatures that can exist in the pipes (exceeding 100 degrees celsius in summer), universal PE-Xa pipes are not suitable. Copper pipes are used instead. Thermal insulation of the pipes is done with Armacell HT/Armaflex, specially designed for high temperature, instead of Armaflex AC.
