  • Why you can't use high-pressure steam boilers on low

    That causes water hammer, which can break just about anything standing in its way. It will also lead to wet steam, which is not of much use when you're trying to heat something. This is why you can't run a high-pressure boiler on low-pressure settings. The boiler manufacturer told the contractor about this when the contractor called to ask.

  • Low Pressure condensing steam boiler Manufacturers

    A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces. Get

    2019-10-18 · A boiler should normally have a water pressure of between 1-1.5 bar. If the pressure drops much below 1 bar you won't get any hot water. Repressurise your boiler. If this is the case, the first step is to repressurise the system by adding more water back in, which is usually done with a key, button or switch depending on the type of boiler.
