Gas Pressure Switches | WA

Gas pressure switches are a key component of your gas train to assure proper safety and operation of your burner. They prove you have adequate pressure to operate and will lock out your burner when you are either too low or too high of pressure. We stock many brands such as Ashcroft, Honeywell, Siemens, Antunes, and Dungs pressure switches.

What Should The Boiler Pressure Be When The Heating Is O

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. Some boilers will also have the critical zones below 1 and above 2 marked in red to help you identify any issues.

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.

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, it is more usual to speak of a steam generator. A boiler or steam generator is used wherever a source of steam is required.
