Novel small-scale liquid alcohol-based heat supply system

The invention discloses a novel small-scale liquid alcohol-based heat supply system which comprises a solar heat collector, a radiator, domestic water equipment and a boiler. The boiler comprises a water tank and a chimney, and a water flow channel is formed in the outer wall of the chimney and used for absorbing smoke heat in the chimney. The water tank comprises an inner water tank body and an outer water tank body, a partition plate is arranged between the inner water tank body and the outer water tank body, and a heat storage system is arranged in the partition plate. A water inlet of the inner water tank body is connected with a water outlet of the solar thermal collector, a water outlet of the inner water tank body is connected with a water inlet of the radiator, a water inlet of the outer water tank body is connected with a water outlet of the water flow channel, and a water outlet of the outer water tank body is connected with the domestic water equipment. The novel small-scale liquid alcohol-based he
