The invention relates to a solar heating system for a building with a cast-in-situ open-web floor, which belongs to a system for providing heat for the building by using solar energy. In the proposal, sunlight is focused on a heat energy receiver by a concentration chip, and then hot air generated by the heat energy receiver is blown to the floor by a fan. The floor is formed by cast-in-situ of thin-walled box bodies; the thin-walled box bodies form a hot air cycle channel in the floor by using connecting channels; the hot air heats the floor after entering the floor, so the entire floor becomes a heat dissipating integration. The lower part of the thin-walled box bodies is provided with an air outlet leading to a room; when the air outlet is opened, the hot air is discharged to the room directly to heat the room quickly. The proposal makes use of the energy of the nature, so the solar heating system is clean and environment-friendly and saves cost and power; besides, the proposal makes full use of own structural characteristics of the building to avoid the problems of installation of additional devices and space occupation.

A solar heating system for use in combination with a forced draft heating system for heating ventilation air of a building. The solar heating system includes a solar collector assembly for heating a liquid circulated through the assembly. The heated liquid is stored in an insulated storage tank where it can be circulated through a heat exchanger positioned in an air duct of the forced draft heating system as need to heat air flow through the duct. The use of a liquid as the heat transfer fluid and providing a storage facility for heated liquid permits the heating system to operate for a period of time after the sun sets or becomes ineffective in providing solar radiation until the heat stored in the liquid becomes exhausted. To increase the heat storage capacity of the liquid, one or more heat sinks can be utilized to absorb excess heat from the liquid and then transfer the absorbed heat back to the liquid when an opposite thermal gradient exists. Additionally, the heating system can recover waste heat from hot combustion gases exhausted from a fuel-fired forced draft heating system.
