Hi, we recently became home owners and came with it a lot of headaches. We just replaced an old leaky boiler with a new Burnham gas-fired steam boiler - please see the picture link below. Since day one we got this problem: glass water quickly goes down by 2-3 inches as soon as the boiler fires up, often tripping the lwco, then rises up as quickly as the boiler switches off, and the short cycling continues. The plumber thought the lwco was bad and replaced it several times, yet the problem continues. We also heard loud sound of water running in the radiators. My question is 1) can an expert tell us if there's a problem with near boiler piping (see pic), and 2) should we skim the boiler - our plumber didn't install a port for that, should we ask him. Also, can someone recommend a steam heating specialist in the NYC area. Very much appreciate your response.
