Dissipation systems serve to transmit heat from the boiler or housing deposit. In this section we treat 3 systems: underfloor heating, fan coil and radiators.

1) Underfloor heating, consists in pumping water at medium temperature (around 40°C) through circuits linked polyethylene pipe.

On the floor we install a layer of insulation with a thickness of 4.5 cm placed in isolation polyethylene tubes. On pouring pipe insulation and a layer of cement mortar that absorbs heat dissipated by the pipes and gives it to the pavement, which emits this energy to the premises by radiation and to a lesser extent by natural convection.

From the collector feed and return circuits are based issuers. From there, the circuits are hydraulically balanced, and through electrothermal printheads, it regulates flow according to the thermal requirements of each store (room).

The regulation of underfloor heating systems gives water to the desired temperature and also independent control each of the premises (rooms) heated.

The fan coils are the first choice when it comes to heat and cool a house with the same system..

Advantages: Serves to cool and heat your home. Systems of low temperature highly effective that works very well with solar energy. Very economic system when it comes to installation. Invisible system. (No dusty as radiators or fan coils).. Healthy system for air circulation and dust is reduced. Módulo de envío de calefacción. Disadvantages: It is difficult to install in existing homes as it involves lifting the soil.

Fancoils.

2) Fan coils are units that incorporate a radiator and fan noise. Through the fan heat can be delivered to ambient temperature, but the internal radiator heat will not be much higher than the environment. It is about a heating system with low temperature (like an underfloor heating) that has one more advantage: With the fan coils you can also cool a room.

The fan coils are connected to a central system that comes with cold water and hot water. The hot water is produced by the solar system and for example a heat pump. The cold water for air conditioning is caused also by the heat pump which also produces cold.

The fan coils are the first choice when it comes to heat and cool a house with the same system.

Advantages: Serves to cool and heat your home. Low temperature highly effective systems that works very well with solar energy. Disadvantages: The installation cost is relatively high. If you want cool the rooms, drains must be needed for each fan coil. Each fan coil needs an outlet. The fan coil motor can be heard, so it is not very comfortable inside the bedrooms..

Radiadores.

3) Radiators are the most popular heating system in Spain. Radiators worked as a high temperature heating system; therefore the combination with solar energy becomes less profitable. However, radiators can be dimensioned as low temperature radiators. This can be done by choosing radiators with more surface area.

Advantages: Heat the room very quickly. Disadvantages: Nowadays they are more expensive to install than a underfloor heating system. High-temperature systems, inefficient. . The potential of solar energy savings are significant lower than with underfloor heating.
