Heating and hot water supply for the boiler system using solar heat

摘要

PPROBLEM TO BE SOLVED: To minimize waste of energy by preventing unnecessary operation of a boiler and a heating load due to its operation in a boiler system for heating and hot water supply using solar heat. PSOLUTION: In the boiler system for heating and hot water supply using solar heat, low temperature water and high temperature water are separated and stored per temperature in a thermal storage tank 5 and a hot water storage tank 11 by a convection effect of hot water, solar heat absorbed in a heating medium is substantially effectively used in heating of the hot water, and at the same time, an amount of the hot water necessary for heating and hot water supply is sufficiently secured via continuous hot water supply from the thermal storage tank 5 to the hot water storage tank 11, and heating and hot water supply by solar heat or an auxiliary boiler 20 can be selectively carried out in accordance with internal temperature conditions of a supply convection pipe 10 and a hot water storage tank 24.
