What is Boiler Pressure?

Boiler pressure refers to the amount of water circulating within the heating system. The boiler operates within a certain pressure range to ensure optimal performance and heat distribution throughout your home.

How Do I Check if My Boiler Pressure is Low?

To check your boiler pressure, refer to the boiler’s pressure gauge. It’s typically located on the front of the unit and displays the current pressure level. If the reading is below the recommended range, it indicates low pressure.

What Causes a Boiler to Lose Pressure?

Pressure Loss Due to Water Leakage

One of the primary reasons for pressure loss is water leakage within the heating system. Leaks can occur in pipes, valves, or even the boiler itself. Inspect your boiler and surrounding pipes for any visible signs of water leakage.

If you suspect a leak, you can perform a visual inspection to check for any drips or puddles around the boiler. Additionally, pay attention to any unusual noises, like hissing or gurgling, which might indicate escaping water.

Can a Boiler Lose Pressure Without a Leak?

In some cases, pressure loss might not be due to visible leaks. Other potential reasons include the bleeding of radiators, which can cause pressure to drop temporarily. Additionally, a faulty pressure relief valve or a system that hasn’t been properly filled can also lead to low pressure.

Losing Pressure Due to a Boiler Fault

Sometimes, pressure loss is a symptom of an underlying boiler fault. Issues with components like the expansion vessel or pressure gauge can lead to pressure fluctuations. In such cases, it’s essential to have a professional boiler repair service like Morland & Martin Plumbing & Heating Ltd assess the boiler for an accurate diagnosis and appropriate repairs.

How to Re-Pressurise Your Boiler

Before re-pressurising your boiler, consult the manufacturer’s manual for specific instructions, as different boilers may require different procedures. Generally, you can re-pressurise your boiler by using the filling loop and adding water until the pressure gauge is within the recommended range.

If in Doubt, Consult a Professional
