A coalescing removal separator includes a separator tank having a separator input configured to receive a fluid flowing through a system having entrained gasses and solid particles, having a tank wall configured to form a volume/chamber inside the separator tank to process the fluid, and having a separator output configured to provide processed fluid that is free of at least some of the entrained gasses and solid particles; and a coalescing media arranged in the volume/chamber of the separator tank, the coalescing media having at least one helically wound brush with a stem and intertwined bristles substantially filling the volume/chamber of the separator tank and being configured to enable the at least some of the entrained gasses and solid particles to come out of the fluid.

A hot water heating system is provided with: a hot water heating device; a heating terminal; a heat circulation circuit; a circulation means; and an expansion-absorbing means. The hot water heating device is provided with: a heating passage; a heating means for heating a heat medium inside the heating passage; a pressure detection means; a supply passage connected to the heating passage; an opening/closing means for the supply passage; and a control means which opens the opening/closing means to supply the heat medium when the internal pressure of the heating passage is less than a reference value. The control means determines that the positional relationship between the circulation means and the expansion-absorbing means is inappropriate when the pressure detected by the pressure detection means at the moment the circulation means starts to be driven is lower than the pressure detected prior to driving the circulation means.
