Valsir S.p.a
Waste and water
supply systems, underfloor heating system
and flush cisterns


Flush cisterns

Valsir’s attention to the responsible use of resources, in particular a precious commodity such as water has inspired investments in research and technological innovation of its products, to offer the market technologically advanced solutions that respect the environment.

An example of this is the range of in-wall and external cisterns that provides the possibility of a dual flush (7.5/4 litres or 6/3 litres), allowing the user to choose the most suitable quantity of water, constantly guaranteeing an effective flush.

Valsir has developed cisterns that are capable of performing a total flush with just 4 litres of water, thus obtaining the valuable 4Star certification.

By using our flush cisterns, a family of 4 can save up to 11,000 litres of water in one year… the equivalent of 7,300 one and a half-litre bottles of water! Or in other words, the yearly consumption of drinking water of 20 children that live in the “Countries of thirst”.


Yearly water savings equal to::

11.000 one-litre bottles

Equal to the consumption of water of:

245 showers

Radiant systems

Radiant panels are ideal for achieving a low temperature heating system and at the same time ensuring an elevated level of comfort, thanks to the uniform distribution of heat inside the room. Valsir radiant systems maximise thermal wellbeing, increase the level of air quality, take advantage of low temperature energy while reducing heat loss and increasing energy savings to the benefit of the environment.

In a household made up of 4 members that is heated with a floor radiant system, energy savings of up to 20% have been registered as compared with traditional heating systems.

The reasons? The fact that it is the entire floor surface that contributes to heating the environment and that this is done by using low temperature water, at approximately 30-40°C. This in fact makes it convenient to use high efficiency heat sources such as heat pumps, condensation boilers, solar panels.

In addition, the condition of ideal well-being is reached with a floor heating system, producing an average room temperature that is 1°C below that of a traditional heating system and therefore with equal comfort levels there is an energy saving that in our gas bills can reach a further 4-6%, and all in favour of the environment.

Possible energy saving:


Compared with a traditional system

CO2 emissions avoided in one year:

The Rainplus® system for the syphonic drainage of rainwater features the most modern technology in the field of drainage from the roofs of medium to large size buildings.

Rainplus® allows the entire flow of water to be directed in an extremely efficient manner to any part of the building whatsoever thus allowing the simple implementation of the most modern rainwater harvesting systems.


This system allows the accumulation of water for use in irrigation and fire-sprinkling system or tanks where the water is used for non-potable purposes without the need of installing special pumps.

This produces savings not only in terms of the purchase of pumps but also in functioning and maintenance costs.

The technology behind the Rainplus® system fully meets current energy saving requirements, guaranteeing greater levels of performance than any other conventional rainwater drainage system.

By installing a Rainplus® system there is a 70%* reduction in the quantity (kilogrammes) of material installed thus drastically cutting transport costs, the manpower required and the space occupied by the system, and that’s not all. The use of 70% less material can also be seen as a contribution to reducing the quantity of CO2 released into the environment for the production of the pipes and fittings required for the system.

There is an 18%* reduction in energy consumption related to the welding of the pipes and fittings and a 36%* reduction for the installation of the outlets on the roof thanks to the high performance of the same.

The comparison


A conventional drainage system
100 kg of HDPE

30kg rainplus

A Rainplus® drainage system 30 kg of HDPE



Emissions of CO2 avoided:

23,5 Kg



In winter months and in certain geographical areas, the opening of a bathroom window to let in fresh air or to let shower or bath steam out can generate a sharp drop in the temperature of the room with a consequent loss of heat and the need for more energy in order to reach the former temperature.

This waste can be avoided by installing Ariapur, the dual extraction fan that extracts odours directly from the WC and extracts any vapour from the room.


Valsir HDPE and Triplus are certified as Green Building products

The Green Building Council of Singapore issued the Green Building mark for Valsir Triplus® and Valsir HDPE

The certification was issued following an in-depth assessment of four significant aspects in order to define the products as “green”:

  • the production process,
  • the recyclability of the product,
  • the installation process,
  • the system solutions.

Production is performed inside the production site of Vobarno, a highly energy efficient building that obtained a class A efficiency rating.

Green Building

Triplus® and HDPE are completely recyclable

A product can be considered “green” when the process required to install it is also environmentally friendly. To construct systems in HDPE and Triplus® no chemical toxic cements or glues of any type are used.

Joints are created by welding at a low voltage or with a push-fit connection socket with a watertight seal.

The capacity of supplying the market with system solutions that respect the environment and reduce, for example, the number of pipes and fittings employed in a waste or rainwater drainage system.

Both Triplus® and HDPE allow waste and drainage systems to be constructed with a single waste stack and therefore without the need for a second ventilation pipe thanks to the use of ventilation branches.

This particular waste system requires the installation of a special fitting on each floor to which the sanitary appliances are connected and with which it is possible to guarantee excellent ventilation of the pipes and a reduction in pressure fluctuations within the system (for more details: Triplus®, HDPE).

HDPE can also be used to create Rainplus® syphonic drainage systems for the collection and re-use of rainwater, significantly reducing the quantity of pipes and fittings in complete respect of the Green Building principles.
