How to Increase Steam Pressure in a Water Boiler

Increasing stream pressure in your water boiler is essential to allow for comfort heating. The boiler must be at the right temperature to provide leeway for water to circulate well in the radiators. What PSI should my boiler be at? The most preferred pressure is between 1 and 2 bars but this will vary depending on the type of boiler.

At times the pressure may be too low and this might hinder its normal operation. In this guide, you will learn how to increase steam pressure in a water boiler. Here’s a step by step guide of the process:

Step 1: Check Pressure Gauge

A random look at the steam boiler pressure gauge is enough to indicate the steam boiler operating pressure. However, the signal may come out in different forms depending on the type of boiler.

Step 2: Low Pressure

When the pressure is too low the first thing that crosses your mind is how do I increase the PSI in my boiler? The process is very simple.

Step 3: Switch Off Boiler

Before you begin the process the boiler must turn off and cool. You don’t want to work with a hot boiler since you might get injured in the process.

Step 4: Find the Filling Loop

The filling loop is under the boiler with a small valve at both ends. Ensure that each end of the hose is secure and attached to the valves.

Step 5: Use a Flat-headed Screwdriver

With the help of a flat-headed screwdriver open the valves by the tap handles. This will provide room for the cold mains water to fill the system. Wait until you hear the water making its way through the system.

The pressure will rise, but you should ensure that it doesn’t surpass the 1.5 bar mark. You can proceed by closing each valve one at a time. Once the boiler reaches the desired temperature, switch it on and then reset it.

Hopefully, with the steps above you have been able to increase steam pressure in your water boiler. You can now happily enjoy a warm shower without any inconvenience.
