Heat accumulator for supplying heat to e.g. sanitary network, has three-way bypass valve mixing coolant in accumulator and distribution boiler, and control board regulating temperature and opening of pump and bypass valve

摘要

The accumulator has an external tank (7) comprising ceramic wool insulation (6), where the tank is made of stainless steel or heat resistance plastic material. Fusion heaters (1) made of aluminum or copper alloy are provided with superimposed double stainless steel streamers (3). Top and bottom compression plates (9) permit conductivity between the heaters. A transfer pump (11) transfers a coolant. A three-way bypass valve (12) mixes the coolant in the accumulator with the coolant in a distribution boiler. A control board (10) regulates temperature and opening of the pump and bypass valve.
