Generally, this is a mechanism providing indoor heating via underground concealed conduits with hot water circulation. Required heating of the system is provided by warm water at 40-50 C°; the energy supply can be provided via all kinds of solid and liquid combustibles or absorption of solar radiation, especially “Heat Pump Solar Collector” integrated system. With underfloor heating systems a homogeneous temperature distribution will be achieved. There is almost no heat difference between the rooms. The heat buildup in the ceiling which is observed in conventional heating system is eliminated in this system. As the heat is stored in structural elements of the building; the thermal comfort is not affected importantly from sudden temperature changes. To disable the leakage of the heat at inferior place, before laying pipes the insulation materials should be installed.
These kind of heating systems are used in places requiring a hot floor such as apartments, Villas, Schools, Hospitals, Churches, residence buildings, Turkish baths, swimming pools, greenhouses, airports, roads, football field, etc.
