Underfloor heating is a heating system in which the thermal energy comes from the inside of the floor. Special pipes are placed throughout the underfloor surface so the hot water is circulated in them. In this way the space is heated uniformly at a fixed temperature, without air flows created as in other heating modes (radiators, fan coils, etc.) and the room temperature distribution is the best possible.
The AND Underfloor Heating/Cooling System has been developed for this exact reason and meets all the criteria for an ideal and healthy climate in your home, since the large radiant surface that is created increases the thermal comfort range.
The result is to enjoy the perfect climate all year round, the desirable thermal comfort and the unique benefits that provide a "higher" quality of life:
Radiation systems achieve energy savings of 12% to 20% on an annual basis, because these systems work at low temperatures and create a relaxing atmosphere at room temperature of 20 degrees or less (compared to 22 degrees or more, required in conventional heating systems with radiators).
In addition, the operating cost of the system can be reduced to the absolute minimum by combining a heat pump in order to use the energy stored in the atmosphere and to work independently from expensive sources of energy such as oil.
High Sanitation Level
Underfloor heating and cooling systems are pure radiation systems, so they achieve a low operating temperature, similar to room temperatures.
This automatically creates better hygienic conditions as the slightly heated surface - due to the small temperature differences - does not create air flows and dust recirculation, as the conventional radiator heating.
A flooring system, which during the winter period creates ideal thermal comfort conditions, can also be used for cooling during the summer season. The underfloor cooling system is a silent solution that does not generate air drafts and combined with a heat pump, can reduce the total system's operating cost to minimum.
Better Use of Spaces - No more exposed heat radiators
With a floor heating and cooling system, all the exposed heat radiators and air conditions are removed. This results in complete freedom in the formation of spaces, since the place is freed from everything that prevents its formation.

Materials for Underfloor Heating Systems AND floor heating
AND molded plates
Floor Heating and Cooling System using molded plates - for new constructions and renovations.
The molded plates are used in a wide range of applications using a 17X2.0 mm PEB cross-linked polyethylene flexible tube.
The installation is easy, with the possibility of diagonal laying and without the use of additional support materials. It offers the possibility of low height applications and creates a water vapor barrier in the paving area.
Floor heating and cooling system with special pipe hooks on thermal insulation boards - for new constructions and renovations.
This system facilitates the paving of the pipe with asymmetric geometric spaces and allows all types of floor heating and floor heating system.
Distribution and Automation systems
Underfloor heating and cooling systems are completed with the distribution and automation program including collectors, thermostats, electrothermal heads. All of these individual components are part of the most modern integrated heating and cooling system floor: AND floor heating.
AND Floor heating system collectors are non-corrosive, stainless steel INOX, cross section 1 and 3/4 Eurocone outputs with regulating switches, with flow meters and thermostatic return switches for actuating actuators 24Vac or 230V , with evacuation valves, ventilators, thermometers on both bars and a set of supports. They start from 2 facilities and reach 12.
The collectors can optionally be installed in special white galvanized panels with a detached door and lengths from 400mm to 1000mm for the 509B series and 600mm to 1200mm for the 513 series.
Room Autonomy / Automation
For individual room autonomy, actuators 24Vac or 230V are mounted on the collectors, which are connected to the system thermostats with an accuracy of ± 0.5 ° C.
