High quality heating boilers are designed for the operation in closed heating systems with the possibility of installation of circulated pump.
Italian automatics SIT provides the stable operation of the boiler at a very low pressure. If the nominal gas pressure for heating boilers АОГВ is 1,3 kPa, the stable boiler operation is possible at 0,6 kPa (50 % from nominal pressure).
