Abstract

PURPOSE: To enable to perform the suitable temperature control even when an abrupt external disturbance occurs by further performing fine adjustments by the deviation between the set temperature and the hot water supplying temperature while performing a basic temperature control based upon the variation in the necessary calory to occur in accordance with the variation in the water supply temperature and the water supply flow quantity.
CONSTITUTION: A first temperature senser 2 for detecting a hot water supply temperature TO is provided on the outlet side of a heat exchanger 1, and a second temperature senser 8 for detecting a water supply temperature Ti and a flow quantity senser 7 for detecting a water supply flow quantity q are provided on the inlet side. The output signals of respective sensers 2, 8 and 7 are supplied to a computing part 9 wherein a necessary calory Q is computed in accordance with Formula I, where a represent a specific heat, η, a heat exchange efficiency; ad Ti and To, output signals of the temperature sensers. A signal corresponding to the necessary calory Q thus obtained is supplied to a driving part 4 to control the combustion quantity of a gas G in the burner 5. Thereafter, a fine adjustment of the combustion quantity of the gas is performed so that the temperature To coincides with the set temperature Tsp by the feedback signal of the water supply temperature To.
