down to the pressure needed for your system prolly 12-18psi. once u do that shut off the valve that feeds the boiler for a day or 2. if the pressure doesn't rise we found the problem. so u say the pressure from the road is high how high? you might need a pressure reducing valve for the house to bring it down to a manageable pressure. u might

Heating System Has Been Overfilled. The first and most obvious problem that leads to high boiler … Over 30 psi boiler pressure will cause the pressure relief valve to open. Typical operating temperature settings on a boiler call for a Low temperature (boiler cut-in) between 120 and 160 °F. Typical operating temperatures on a hydronic boiler call for a high temperature (boiler cuts off) of 180-200 °F.

Oct 27, 2016· A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.

a) insufficient air supply to the fires due to the pressure drop across the heater b) corrosion of the heater due to low stack temperatures c) excessive back pressure in the furnace due to low flow rates d) localized heat stressing of air heater surfaces

A properly sized furnace or boiler will operate most efficiently, and you'll want to choose a dependable unit and compare the warranties of each furnace or boiler you’re considering. When shopping for high-efficiency furnaces and boilers, look for the ENERGY STAR® label.
