ELECTRIC HEATER AND OIL GAS BURNER COMBINATION BOILER SYSTEM AND CIRCULATING PUMP CONTROLLER

摘要

PURPOSE: An electric heater and oil gas burner combination boiler system and a circulating pump controller are provided to control a circulating pump by sending heating water to each area according to a preset temperature. CONSTITUTION: An electric heater comprises Circulating pumps(45,50) are operated and stopped according to the sensing temperature of the water circulation temperature detection sensor. The circulating pump is stopped when the water circulation temperature value is increased by 5C. If the circulating pump again is unable to reach the water circulation temperature setting temperature value. If the water circulation temperature reaches a fixed temperature the circulating pump is stopped.
