How To Repressurise Boiler

If you’re experiencing low pressure in your boiler, you may need to repressurise it to ensure it continues working efficiently. This is a simple task that you can carry out yourself, and in this article, we’ll show you how to do it.

Step 1

Identify the Pressure Gauge

The pressure gauge is usually located on the front panel of the boiler. It looks like a small round dial with numbers on it. The pressure gauge measures the pressure of the water inside the boiler and is an important tool for checking its health.

Step 2

Check the Current Pressure

Before repressurising your boiler, it’s essential to check the current pressure. The pressure gauge should read between 1 and 1.5 bar when the boiler is not in use. If the pressure is below this range, you need to repressurise the boiler.

Step 3

Turn off the Boiler

To ensure your safety, it’s vital to turn off the boiler before you start repressurising it. Locate the on/off switch on the boiler and turn it off.

Step 4

Locate the Filling Loop

The filling loop is a small hose that connects the boiler to the mains water supply. It’s usually located underneath the boiler and can be identified by its flexible metal hose.

Step 5

Open the Filling Loop Valve

Once you’ve located the filling loop, you need to open the valve to allow water to flow into the system. The valve is usually located on the filling loop itself and can be opened by turning it 90 degrees.

Step 6

Repressurise the Boiler

With the filling loop valve open, the water will begin to flow into the boiler. Keep an eye on the pressure gauge and stop filling the boiler when the pressure reaches 1.5 bar.

Step 7

Close the Filling Loop Valve

Once you’ve reached the correct pressure, turn the filling loop valve back to its original position to close it. This will stop the flow of water into the system.

Step 8

Turn on the Boiler

Finally, you can turn the boiler back on and wait for it to heat up. Once it’s reached the desired temperature, check the pressure gauge again to ensure it’s still within the correct range.

Repressurising your boiler is a simple task that you can do yourself. By following the steps outlined in this article, you can ensure your boiler is working efficiently and safely.
