  • Low Mains Water Pressure - Installing Combi Boiler to

    2014-12-22 · Hi, I am thinking about having an oil combi boiler put in so that I get good pressure from the mains for my shower. A concern of mine is that the cold water mains pressure doesn't seem very powerful. If I have the sprinkler on in the garden and I turn the cold water on in the kitchen, I can see the sprinkler drop to a very light sprinkle.

    The energy contained in the water being blown down is the liquid enthalpy of water at saturation temperature at boiler pressure. In Example 3.14.1, the boiler pressure is 10 bar g, and from steam tables, hf is 782 kJ/kg. So the rate at which energy is being released from the boiler is: 782 kJ/kg x 6.2 kg/s = 4.85 MW.

    2018-8-5 · High-pressure boilers are typically used for process loads and can have an operating pressure of 16 to more than 1,000 psig. Most steam boiler systems require saturated steam, which means the water and the steam in the vessel are at the same temperature. Steam and hot water boilers are defined according to design pressure and operating pressure.

    A low-pressure boiler is one that never goes above 15 psig. And since the folks who make boiler-feed pumps like to have a one-size-fits-all pump, they provide one on all their stock units that that will discharge at 20 psig because high pressure goes to low pressure. Always.

  • What is the safe pressure for a hot-water-heating

    In my Cape Cod house, with the boiler on the floor of my garage, the pressure gauge reads between 12- and 15-psi (the dial is too small to read more accurately than that). The maximum pressure I am allowed it to get to is 30-psi, because, at that pressure, the pressure relief valve will open. This is typical of residential hot-water boilers.
