Home heating systems.

1. Home heating systems. Radiators (caloriferi) It is widely used: hot water leaves the boiler and thanks to pipes enters radiators around the house. Then it returns to the boiler to be heated again Storage heaters. (caloriferi a mattoni rifrangenti) The heat is generated in the heater itself which heats fire bricks till they get very hot. The heat is then completely radiated into the air. After that the process starts again. Underfloor heating (Pannelli radianti). There are only pipes placedeverywhere underfloor. The heated water travels as in the radiator system. Heated water pipes heat all the room. Inital high costs, but long term convenience. Wood pellet stoves (stufe a pellet). Open fires(caminetti) and old fashioned stoves (vecchie stufe a legna) are polluting and inefficient. Wood pellet stoves are easy to use( automatic), safe and highly efficient. The pellets are the fuel. They are made of finely ground wood waste which is compressed into hard pellets. From 10 to15 kg are loaded into the hopper and the stove can run automatically for 24 hours. Pellets are slowly released into a small combustion chamber. Vented air systems (sistemi a ventilazione). As in a hair dryer, the air is heated by electrical elements. Ventilation pipes, in the walls, move air around the house. A good filtration system is necessary to avoid dust gathering causing allergy problems.
