Adequate pressure in a boiler is essential for the heating system to operate efficiently, allowing hot water to circulate properly through radiators, faucets and showers. When the pressure drops too low, the boiler cannot maintain the water circulation necessary for home comfort. According to recent studies, it is estimated that 60% of boiler failures are related to pressure problems. In my experience as a plumber in Marbella, this is one of the most consulted problems by my clients, especially when the coldest months of the year are approaching. What does it mean when the boiler loses pressure?
Before explaining how to fix it, it is important to understand what a loss of pressure in the boiler implies and what causes it. In most cases,a boiler that loses pressure is indicating a leak or a fault in the heating system.

What is boiler pressure?
Boiler pressure is the measure of the force with which water circulates through the heating system. Most modern boilers in Marbella homes must maintain a pressure of between 1 and 1.5 bar to operate efficiently, although this range can vary depending on the model.
How to check the boiler pressure?
- Locate the pressure gauge: Most boilers have a pressure gauge on the front panel. This gauge shows if the pressure is at the proper level.
- Observe the pressure levels: If the pressure gauge reads less than 1 bar, it is a sign that your boiler is losing pressure and action is needed to avoid major problems.
Marbella plumbing advice: Performing a monthly boiler pressure check is a good practice to detect any loss of pressure in time.
Why does the boiler lose pressure?
Pressure loss in a boiler can have several causes. Here I explain the most common ones:
1. Leaks in the system
One of the most frequent causes is a leak in the heating system. These leaks can appear in radiators, pipes or even inside the boiler. In cases of serious leaks, it is advisable to contact a boiler repair service in Marbella to ensure a safe and effective solution.
Radiator purge
Another common cause is the bleeding of the radiators, as a small amount of water may escape during this process and reduce the pressure in the system. After flushing the radiators, always check the pressure level of the boiler.
Pressure valve problems
The safety valve is another component that could be failing. If this valve is activated frequently, it may need to be replaced. If you are not experienced in plumbing, I recommend you to go to a professional plumber in Marbella to avoid further damage to your system.
Step by step: How to recover the pressure of a boiler?
If you have already identified that your boiler pressure is low, follow these basic steps to try to solve the problem.
- Turn off the boiler: Before making any adjustments, turn off the boiler and wait a few minutes for it to cool down.
- Find the filler tap: Most boilers have a filler tap or valve at the bottom.
- Open the fill tap: Turn the fill tap slowly to allow water to enter the system. Watch the pressure gauge until the pressure approaches 1.5 bar.
- Close the tap: Once the pressure is in the proper range, close the tap and turn on the boiler.
When to contact a plumber?
Sometimes, loss of pressure in a boiler indicates a major problem that cannot be solved with simple adjustments. Here are some cases in which it is best to call a plumbing service in Marbella:
- Visible leaks: If you find puddles of water near the boiler or in the piping system.
- Unstable pressure: If the pressure keeps dropping despite refilling the system.
- Inactive boiler: If the boiler shuts off automatically or does not produce hot water consistently.
Tips to avoid future pressure losses
- Check the boiler regularly: Frequent pressure checks will help you identify potential problems early.
- Avoid leaks: Perform regular inspections of radiators and valves to make sure there are no leaks.
- Rely on Marbella plumbing experts: Preventive maintenance by a professional plumber in Marbella is an investment that can save you a lot of trouble in the future.
Conclusion
Pressure loss in a boiler can be a nuisance, but with the right information and steps, it’s a problem you can handle. If you notice that the pressure keeps dropping or find any signs of a leak, remember that a professional boiler repair Marbella can give you the help you need. As a plumber in Marbella, my recommendation is to never underestimate boiler pressure problems, as good maintenance is the key to an efficient and long-lasting heating system.
