A thermal storage system includes a solar collector. A first fluid circulating through the collector is piped to a heat exchanger wherein heat in the first fluid is transferred to a second fluid circulating through a heat pump circuit. The temperature of the second fluid is further elevated by the heat pump and is circulated through a second heat exchanger thereby transferring heat to a third fluid. The third fluid is circulated through a third heat exchanger to elevate the temperature of a fourth fluid stored in a high pressure, high temperature storage tank. The fourth fluid is employed to elevate the temperature of a working fluid that may be used for consumption or heating. Alternate embodiments of the fluid system include an accumulator tank wherein heat from the first fluid is transferred to fluid in the accumulator tank. Heat from the fluid in the accumulator tank is transferred to the second circulating fluid or heat utilization means as required. Automatic transfer to a fourth fluid heated by auxiliary means, and stored at high pressure and temperature is provided when the accumulator tank temperature drops below a pre-set valve.
