Why Do Boilers Keep Losing Pressure

Why Does my Boiler Keep Losing Pressure?

The feeling of arriving home after a long day at work, longing to take a shower, and then realizing that there is no warm water in the boiler is one of the most frustrating things that can happen. And one of the possible causes for this is when a boiler keeps losing pressure. But do not panic – it’s straightforward to figure out why boilers lose pressure, and in some instances, you can fix it yourself. All you need to do is look into the problem.

Why Do Boilers Keep Losing Pressure? In this post, we’ll go over the most prevalent reasons for boiler pressure loss and the measures you may take to remedy the situation.

What Exactly is Boilers Pressure?

There are many things to consider when it comes to boiler pressure. However, you will need to educate yourself a little on the operation of your boiler before we can go to the article section that addresses the specific issues and potential remedies for boilers losing pressure.

Boilers heat water and transport it via a network of pipes and radiators to keep you and your family warm and comfortable. So, pressure must be maintained for the appliance to perform its function. Pressure in modern combi boilers is regulated via an internal loop that connects to the cold water supply.

What is The Normal Pressure Level For A Boiler?

As a general guideline, the standard boiler pressure should be between 1.0 and 1.5 bars. And it is pretty straightforward to check the boiler’s pressure. First, find your boiler’s pressure gauge on the appliance’s front panel. This is displayed in a red and green-coloured section part.

Usually, a pressure gauge with a needle in the green area often indicates low pressure (below 1.0 bar), whereas a gauge with a needle in the red portion indicates high pressure (above 2.5 bars). And these are just some of the boiler maintenance guidelines you need to be aware of.

Quick Fix
You can’t just patch up a boiler leak with some duct tape. It’s recommended to contact an experienced gas expert if you see a water pool under the appliance. In general, it’s less expensive to pay for a replacement component than to buy a whole new boiler, even if the damage is severe. Hence, the problem won’t disappear if you leave it leaking. Contact an expert plumbing and heating engineer near you.

A leak in the plumbing system...

If you believe there is a leak in your heating system, you will need to search for it. Locate the problem by following the pipe's path in your home. We suggest searching around the joints and bends since these are the system's vulnerable points.

The malfunctioning pressure relief valve...

As their name indicates, pressure relief valves are intended to release increased pressure when the boiler's pressure reaches or surpasses 3 bars. In most cases, this occurs when the pressure in the boiler rises over the set point, which can make boiler pressure drop when heating off. When a valve of this kind fails, water from the central heating system will begin to seep out of your home at a reduced pressure via a pipe placed outside your property. However, this may happen whether the valve is positioned within or outside your house.

Quick Fix
One of your few options is to check for leaks in the copper line and an expert plumbing and heating engineer plumber to replace the valve. This is where Croston Plumbing & Heating is here to help you! We offer top-notch boiler repair service throughout the North West and surrounding areas.

A corroded or damaged expansion vessel...

When your boiler warms up due to a faulty expansion vessel, the pressure rises to 3 bars. This is due to the system's inability to accommodate the expanded water. After then, the boiler's pressure relief valve releases the built-up pressure, allowing the appliance to exit the danger zone safely. This results in a considerable decline in the pressure gauge's readings.

Quick Fix
In most cases, the re-pressurization of your expansion vessel needs to be a component of your yearly boiler service. This, of course, should be a preventative measure to avoid problems like a broken vessel in the first place. However, repairing a broken expansion vessel is neither costly nor difficult, but a competent specialist should always do it.

Broken boiler components...

A broken and faulty component is the final cause of pressure dropping on the boiler every day. However, you don't have to stress yourself about this; the monitor on your boiler will let you know if it isn't functioning correctly and needs to be serviced.

Quick Fix
Undoubtedly, every broken appliance part will need a replacement for optimal condition. In the same way, if anything within your boiler is broken, you should have a professional remove the damaged part and install a new one. However, if the unit is rather old, this might be an excellent opportunity to replace it. For instance, the cost of replacing a heat exchanger might put a severe dent in your finances.
