Description
BOX FIRE BF2 is a preassembled module specially developed to integrate an open circuit solid fuel heat source (Fireplace without built-in circulation pump) to a house heating system normally feeded by an expansion tank Gas Boiler. The module separates the heating sources and manages the functionning of the Boiler based on the temperature of the Fireplace. Moreover, by means of a heat exchanger, it transfers efficiently the heat geneated by the Fireplace to the heating system. Also, by means of a motorized diverting valve, BF2 module can divert the Domestic Hot Water to the Gas Boiler or to the Fireplace with internal HSW production, if the Fireplace is working.
Primary circuit (Fireplace) pump PTC starts when fireplace reaches a temperature of 30° C, then at 70 °C secondary circuit (heating plant) pump PIR starts and simultaneously boiler circulation pump is switched off. From that moment the fireplace heats up the house. All electric components are controlled by means of a control unit FDG.
If Fireplace temperature is higher than 40 °C,The motorized diverting valve VD deviates the water supply from the Gas Boiler to the Fireplace for Domestic Hot Water production.
