Jun 24, 2014· That oxygen comes out of solution as the water boils, and it can eat holes in the boiler, right at the boiler’s waterline. If you decide to feed with hot water instead of cold water, the minerals in the water will come out of solution on the automatic water-feeder’s seat, and that can cause a flood, especially if it’s a one-pipe-steam system.

The water being drained from the boiler is at saturation temperature, and there is a drop in pressure over the orifice almost equal to the whole boiler pressure. This means that a substantial proportion of the water will flash to steam, increasing its volume by a factor of over 1 000.

What it doesn't do is raise the pressure in the boiler. The fact that your 0 to 5 psi gauge doesn't move, and the pressuretrol doesn't turn the boiler off, and the system heats well, simply indicates that your boiler is very well matched to your system. So be happy, don't worry. But do reset the pressuretrol...
