Is it normal for a boiler to lose pressure over time?

If you've woken up this morning and found your boiler has lost pressure for the first time, don't panic. It's a very common occurrence. Over time, or even overnight, your boiler can lose water and therefore pressure. All that's necessary is to top up the boiler or, in other words, to repressurise the system.

How often should a boiler lose pressure?

Ideally, you shouldn't need to top up your boiler pressure very often. But if the pressure drops more than once or twice a year, check all visible pipes for signs of water leaks. You might also find green deposits near joins in copper pipework, or stains on the skirting boards or ceilings.

Can a boiler lose pressure without a leak?

Can a boiler lose pressure without a leak? If you have found no leaks and your boiler is still losing pressure, the cause may instead be a boiler leak, a hidden leak on the system.

What causes the pressure to drop in a boiler?

What Causes a Boiler to Lose Pressure and How to Fix It? There are many reasons behind a boiler losing pressure. They can range from a faulty pressure relief valve, recently bled radiators, a problem in the expansion vessel, to a huge leak in the actual pipework.

The reason we top up the system when it has cooled is that when the central heating heats up the water expands and causes the pressure to increase, this is normal and no need to worry, but if you have the initial pressure too high it means when the water heats up it will over pressurise and will then discharge through ...

Why does combi boiler keep losing pressure?

Why do I have to keep adding water to my boiler?

When new water feeds into a boiler, it introduces new oxygen into the system, and that oxygen causes the oxidation or breakdown of the boiler and its components. If unaddressed this can lower the lifespan of a boiler drastically. A steam heat system, when running well, will need very little new water at all.

What should I do if my water pressure is low?

Is 2.5 bar too high for a boiler?

Your boiler should be running between the 1 bar and the 1.5 bar, which will be in the green section of the boiler pressure gauge. If the bar is hitting over 2.5 bars, then the pressure from the water in the system is too high, and anything below 1 bar is too low.
