Why boiler pressure drops Leeds

You are not alone, and you have noticed that your boiler pressure is dropping repeatedly in Leeds. It is one of the most frequent heating problems house owners have to deal with particularly in colder seasons when the systems are in more serious operation. Whereas the changes in pressure occasionally are normal, frequent drops normally show that there is a problem that should be addressed.

1.This is what makes boiler pressure to decrease, and what you need to do about it.

2.What Does normal boiler pressure mean?

The majority of the modern combi and system boilers such as Worcester bosch, Ideal Boilers and Vaillant should be able to operate between 1.0 and 1.5 bar when cold.

When you have a pressure of less than 1 bar below your pressure gauge, your boiler can:

Stop working completely

Display a fault code

Not be able to generate heating or hot water.

Temporary fix of the problem is to top up the pressure with the filling loop but in case it continues to drop, then there is probably a major problem.

3.Water Leaks in the System

A leak in somewhere in your heating system is the most frequent cause of pressure loss. 

4.This could be:

• A leaking radiator valve
• Corroded pipework
• A slight of joint leakage in floor boards.
• A dripping pressure relief valve.

In older properties in Leeds, leaks may be difficult to notice due to the hidden pipework in the suspended floors.

1.Signs of a leak include:

• Damp patches
• Stained ceilings
• Water around radiators
• Always necessity to repressurise.

Even a drip-drip can cause a steady decrease in system pressure with time.

2.Recently Bled Radiators

When you have just bled your radiators to get rid of trapped air, it is normal that pressure will be found to be slightly lower afterwards. Bleeding eliminates air and a little water that decreases system pressure.

In the present instance, the problem should be solved by merely topping up in the filling loop. There is however a possibility that radiators are regularly required to be bled because of another malfunction.

3.Abnormal Pressure Relief Valve (PRV).

The pressure relief system is constructed in a way that remits water in case the system is over pressurised. When it breaks or gets stuck open it may continuously release water and pressure drops.

You could hear the dripping water in an external overflow pipe on the outside of your house. In that case, this should be attended to professionally.

4.Expansion Vessel Problems

Your boiler has a vessel called an expansion vessel inside it which regulates the pressure as the water is heated and cooled down. Loss of air charge of the vessel or the internal diaphragm will cause up and down pressure, which will usually decrease with dropping of the system.

This is a typical problem with older boilers and typically happens when an engineer has to re-pressurise or replace the vessel.

5.Cracked Heat Exchanger (Uncommon, Non-Serious)

Less frequently may be a cracked heat exchanger will result in internal boiler leaks. It is a more severe defect and might not necessarily be economical to fix and it will depend on the age of the boiler.

This can be diagnosed by a qualified engineer who is registered by the Gas safe Register.

6.Cold Weather in Leeds and Boiler Pressure.

Yes, the change in temperature may cause slight changes in pressure. In extremely cold winters in Leeds pressure can slightly reduce when the system is not in operation and increase when it is. Nevertheless, severe or recurrent declines are not natural and must be researched.

3.What to do when the pressure in the boiler is continually dropping?

• Look for radiator and pipework leakages.
• Checked outside: dripping of the overflow pipe.
• Repressurise the system to 1-1.5 bar.
• Monitor the gauge over 24-48 hours.
• In case the pressure reduces once again, it is time to invite a Gas safe registered heating engineer in Leeds.

Do not keep adding water to the boiler over and over again without addressing the cause of the issue in-flow of fresh water into the system may enhance corrosion and reduce the boiler life.

4.When to Call a Professional

• You are advised to consult a professional in case:
• Pressure decreases on a daily or weekly basis.
• Not a drop of leaking you can see.
• There are fault codes that keep on reoccurring on the boiler.
• The pressure becomes too high then falls.
• You do not know how to repressurise safely.

5.To identify the problem a full system pressure test can be performed by an experienced engineer.

The reduction of boiler pressure in Leeds properties is normally as a result of leakages, defective parts, or enlarging vessel. Topping up pressure may be a short-term solution, but the continued loss of pressure is an indicator of an underlying problem.

Early problem detection avoids loss of time, saves on cost of more costly repairs in the future particularly in cold Yorkshire winters that the most you need is your boiler.
