When the heating is turned on your boiler pressure should be between 1.5 and 2 bar.. Most boilers will highlight this area on the pressure gauge in green to help you see if the needle is pointing to the correct amount of pressure.
qianxin@zozen.com > Get A Quote >Typical industrial boilers are “natural circulation” boilers and do not utilize pumps to circulate water through the pressure vessel. These units rely on the differential density between hot and cold water to provide the circulation.

The main difference is that industrial boilers are dimensioned significantly larger, so their heating capacity is not only sufficient for a family
qianxin@zozen.com > Get A Quote >The standard cold water operating pressure of most U.S. and Canadian hot water boilers is 12 pounds per square inch (psi). If the boiler pressure drops below 12 psi, the valve will allow new water into the unit to bring up the pressure reading.

Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this,

When higher temperatures are needed then alternative forms of heating such as high-pressure hot water, steam or efficient Thermal Fluid systems are used.

Typical pressure for a residential boiler serving a two story home would show 12 psi cold, and less than 30 psi hot. Over 30 psi boiler pressure will cause the pressure relief valve to open.

A leak from your pipes, boiler or radiators can often be hard to spot but take a look around your home for any damp patches and water.
