EFFICIENCY AND ENERGY SAVING; THE REPLY TO NEW REQUIREMENTS.

To maintain the commitments pledged in the Kyoto protocol, implemented in 2005 by Italian Decree 192 and subsequently integrated and replaced by Decree 311, Italy (as well as every other European country) has decided to reduce considerably the emission of pollutants into the atmosphere. To achieve these results, Italy has enacted a plan to improve the energy performance of buildings (Class A, Class B, etc.). The plan foresees an increase in low temperature heat generators. The use of a low temperature heating system and IRSAP radiators provides an ideal balance between meeting the heating requirements of the building and energy savings; thus avoiding the emission of greenhouse gases into the atmosphere. Thanks to their performance, IRSAP products are highly efficient in low temperature systems, allowing excellent heat yields even with small radiators. This means our products can be used with condensing boilers and heat pumps. The ideal ∆t recommended by IRSAP for the low temperature system projects is 30°C. All Irsap Termoarredatori® are tested to function at differen ∆t.

In the Figures 1 and 2 and in schedules A and B on the right illustrate the temperature distribution inside the same environment heated by a high temperature radiator (Photo A) or a low temperature radiator (Photo B). In figure 2 and in the schedule B, the temperature is more even. This phenomenon is due to the improved thermal exchange by irradiation between the radiator and the room. The lower the supply temperature of the radiator, the greater the quantity of heat transmitted by irradiation.

Room heated with a high temperature system: a high degree of stratification.

Room heated with a low temperature system: reduced stratification and better comfort

Low thermal inertia, together with an ability to exchange high percentages of heat by irradiation, make IRSAP radiators the best heating system terminal to rapidly reach the optimum working temperature, guaranteeing considerable flexibility in ideal climate management. Tesi radiators are the best way to combine energy efficiency with COST REDUCTION.

The vertical thermal gradient, or stratification within an environment, is more than halved (see Figures 1 and 2), reducing to 45°C the radiator inlet water temperature. This type of system management improves consumption and especially comfort.

Termoarredatori® Irsap can even function with an inlet water temperature below 55°C (that is designed with an ∆t at 30°C). This result is achieved thanks to the large exposed surface area and its shape, able to guarantee excellent radiating and convective heat exchanging properties. The graph above illustrates how the heat yield of a TESI steel tubular radiator is just slightly different from the heat yield of an irradiating panel (ideal radiating heat yield). The lower the supply temperature of the radiator, the greater the difference in performance between steel and aluminium.

IRSAP Termoarredatori® really are the most suitable radiators for the new generation of heating systems.

Irsap termoarredatori® are tested to function at different ∆t. These certified tests guarantee perfect compatibility with modern low temperature heating systems meeting demands in terms of energy savings and excellent wellbeing. In this price list, this mark indicates every product certified to function with low temperature systems.

IRSAP has undertaken a new virtual path from a green standpoint, better known today with the name ECO DESIGN, taking action to achieve product design that respects a philosophy of responsibility from many points of view: first of all environmental, but also ethical and social.

Through the use of renewable resources, materials and production processes, there is less impact on the natural environment. Our factories satisfy about 70% of their electrical requirements with renewable sources, thanks to specially made photovoltaic systems, with a yearly saving in the emission of carbon dioxide of about 5 million kg.

In this way, IRSAP gives the company a greater value than that which has been taken from the environment and elsewhere during the entire production process; ECO DESIGN principles are in fact applied to all the phases of the product’s life cycle, with the aim of reducing its overall environmental impact: from the purveying and use of the raw materials, which must be reusable, biodegradable, recyclable and non-toxic, to their processing in the production stage and to distribution.

All these phases respect the EU Directive on ECO DESIGN (2009/125/EC), in terms of energy efficiency (reduced energy consumption in the productive phases) and reduced environmental impact.

All our fixed electrical appliances for heating the local environment present a seasonal energy efficiency of 38% or higher (EU Regulation 2015/1188).
