Lastly, some boilers have a domestic hot water coil for making hot water for showers, washing dishes, so on and so forth. Sometimes, after prolonged use, a domestic coil inside the boiler jacket can develop a pinhole in the tubing. If this happens, the boiler pressure is affected by pressure from the domestic coil.
Oct 24, 2018 · 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. And to get water into a boiler that’s operating at 15-psi, you need to have at least 20-psi.
Steam or Hot Water. Steam boilers are designed for low-pressure or high-pressure applications. Low-pressure boilers are limited to 15 psig design, and are typically used for heating applications. High-pressure boilers are typically used for process loads and can have an operating pressure of 16 to more than 1,000 psig.
What pressure should my boiler be? Your boiler's pressure is usually displayed on the boiler's built-in pressure gauge, and should read around the 1 bar mark when you are not running any hot water and the central heating is not turned on. Therefore, 1 bar is a low-pressure setting. Why is my boiler pressure high?
Low pressure boilers are most frequently used for generating steam rather than for heating water. Because boilers do not control the pressure or flow of hot water into a shower head, for example, low pressure boilers would offer little difference from any other boiler like a combi boiler.

The pressure at the boiler through another gauge reads 20 psi. The boiler is in the basement. There are 4 pumps. Here the sequence: 1) Pump for radiant heat through the subfloor (about 1000 feet of 3/8" pex) on first floor (covers about) 1,200 square feet 2) Pump for the hot water holding tank (run is about 5 feet supply and return)
If your boiler pressure reads less than 1 bar, it’s possible that you might have lost water from the system, which needs to be replaced. This is where that filling loop (or filling link) comes in again! If the pressure gauge on your boiler indicates high pressure (above 2.75 bar), then you may need to bleed a radiator to bring the level down to around 1.5 bar. This can be tricky and, occasionally, dangerous; due to high water temperatures.
Based on pressure steam boiler can be classified as high pressure steam boiler and low pressure steam boiler.

Most plumbing codes require a reducing valve to keep the water below 80 psi pressure, so ideally your pressure could be between 50 and 80 psi. Less than 40 would be of concern. If you have 80 or so upstream of the hot water generating equipment, try taking a reading downstream, both while water is running. This will give you a "pressure drop" reading.
The pressure for hot water boilers will vary from the boiler system to the boiler system. Most boilers operate with a pressure of 12 PSI. Again, that pressure will differ from one boiler to boiler.
