ABSTRACT:
A solar heating system including a specially designed tank divided into zones in which heat is stored in water, the hottest water in each zone rising to the top thereof by convection. A solar flow circuit draws water from the bottom of the coldest zone, and delivers it through a solar heat collection device back to the bottom of the hottest zone it is capable of heating. A heating flow circuit is drawn from the top of the hottest zone and delivered through a heat dispersing device in a comfort zone back to the top of the coldest zone, and then across the tops of the zones back to the hottest zone. An auxiliary heater fired by external fuel is provided to supply heat when the solar unit cannot carry the heating load. Provision is also made for collecting heat from any other external source available and storing it in the tank, so as to reduce any load on the auxiliary heater. In all cases heat supplied to the tank is inserted into the hottest zone thereof in which it is capable of elevating the water temperature, so as to render that heat more quickly and readily available for heat load use.
