SUNSYSTEM SON 750L
Models of the SON series have two built-in spiral heat exchangers for connection to a solar collector (solar plant) or a heating boiler. It is possible to connect 2 electric heating elements (heating elements). The boilers have a large and convenient inspection hole located at the bottom of the tank, this provides access for maintenance and cleaning of the water heater. Also, instead of the flange cover, you can install a heating element. The second heating element is threaded (1 1/2″), installed in the upper part of the tank, from 3 to 7.5 kW.
In the SON 750 boiler, there are two heat exchangers. A coolant passes through one (heated by a heating boiler), which gives off heat to the water in the tank. Then the “cooled down” coolant returns back to the boiler for reheating, and this continues until the water in the boiler reaches the desired temperature. The second heat exchanger can be used to work with a solar collector or other heat source, such as an electric or solid fuel boiler or fireplace. Since the boiler is designed for floor mounting, it has an upper supply of cold and hot water. An important feature of the boiler is the presence of a recirculation circuit in it. A key feature of this device is the presence of full protection against corrosion processes. The SON line of indirect heating boilers, produced by the well-known company Sunsystem, are famous for their very low energy consumption with high efficiency. Such a model range is usually located in residential or industrial premises. Important advantages of this series were the presence of high-quality insulation and two heat exchangers with a large surface.
