Why Is My Boiler Losing Pressure?

Why Does A Boiler Lose Pressure?


A boiler can lose pressure for various reasons, including internal component faults or system leaks. As a modern boiler operates as a sealed system, maintaining a stable pressure is essential to ensure water flows efficiently through your heating system.

While low boiler pressure isn’t dangerous, it can affect the system’s efficiency and performance. This is one of the things an engineer would check for during an annual boiler service.

What Are The Signs of Low Boiler Pressure?


If you suspect that your boiler is losing pressure, be on the lookout for the following signs:

  • Reduced Heating Performance – Your radiators may not heat up properly or take longer than usual to warm your home.
  • Loss of Hot Water – If you notice a decrease in hot water supply, it may be due to low boiler pressure.
  • Boiler Lockout – A boiler lockout occurs when the boiler’s safety mechanisms shut down the system due to low pressure, causing it to stop working.
  • Dripping or Leaking Water – Visible leaks or dripping water around the boiler or pipes can indicate pressure-related issues.
  • Constantly Needing to Top Up – If you find yourself frequently topping up the boiler pressure, it’s a sign that there’s an underlying problem.

How Do I Top Up My Boiler Pressure ?


Topping up your boiler pressure is a simple process that you can often do yourself. Locate the filling loop, which is usually a flexible silver pipe with taps, and make sure the boiler is off and the system is cold. Open the taps to let water into the system until the pressure gauge reaches the recommended level.

While you can top up your boiler pressure yourself, it’s essential to know when to seek professional assistance. If you’re unsure or uncomfortable performing the task, it’s best to contact a registered Gas Safe engineer.

Warmable can connect you with qualified engineers who can expertly diagnose and resolve any boiler pressure issues.

Should I Consider Boiler Replacement If My Boiler Is Losing Pressure?


Boilers have a lifespan, and with age, their efficiency and reliability may decline. If your boiler is older and requires frequent costly repairs, it might be time to consider a new boiler installation or boiler upgrade.

Warmable can match you with a local engineer and fitter who will offer free quotes for new boiler installations, giving you the opportunity to explore various options and select the best solution for your home.

My Boiler Is Still Losing Pressure – What Should I Do?


If your boiler continues to lose pressure even after topping up, it may indicate more significant issues that require professional attention. Common causes include boiler leaks, system leaks or faulty boiler parts. Attempting to resolve these problems without expertise can lead to further damage.

How Much Does It Cost to Repair Pressure-Related Issues in a Boiler?

How Much Does It Cost to Repair Pressure-Related Issues in a Boiler?


Getting your boiler repaired could cost you between £90 and £400. More minor faults, such as getting an air pressure switch, will cost you about £100 to £200.

However, the cost of repairing pressure-related issues in a boiler can vary depending on the extent of the problem and the necessary repairs.

Is Pressure Loss Covered Under Boiler Warranties?

Can I Continue Using My Boiler if It Is Losing Pressure?


No. While a slight pressure drop is normal over time, significant and continuous pressure loss can lead to boiler malfunctions and potentially dangerous situations. You need to fix or address pressure loss as soon as you can, to prevent further damage.

If you notice your boiler losing pressure, take the necessary steps to repressurise it and investigate the cause of the issue. You can do this by working with a trained Gas Safe registered professional.

How Often Should I Check My Boiler’s Pressure?


Aim to check the pressure at least once a month, especially during colder months when the boiler is used more frequently.

Regularly checking your boiler’s pressure is a good practice to identify any pressure-related issues promptly by contacting an expert.
