Boiler Pressure Too High – Find Out Why and How to Reduce it

The correct pressure for your boiler is essential to ensure the effectiveness and security of the central heating unit. If your boiler's pressure is too high, this could cause long-term damage, more expensive energy bills, or even a failure. If you've just relocated to a new house or observed unusual fluctuations in your heating efficiency, this guide can help you understand the cause of the high pressure on your boiler and also ways to lower it without risk.

In this article, we'll discuss how Boiler installation London experts and dependable London Boiler Service providers can help you keep your heating system in good working order.

What Is the Correct Boiler Pressure?

If the boiler is cold, the optimal boiler pressure should range between 1.0 and 2.0 bar. This ensures that the water circulates efficiently throughout the radiators and heating system without straining the internal parts.

When the pressure goes over 2.5 bar, particularly when the system is turned off or not being used, it's an indication that something is wrong and requires urgent attention.

Common Reasons for High Boiler Pressure

Many factors could cause excessive boiler pressure. A few of the most typical are:

Boiler that is overfilled: Do not add too many gallons of water while repressurizing your boiler.

Faulty Expanding Vessel: If the internal component is damaged, it won't absorb the pressure causing it.

Limescale build-up It is common in zones with hard water, like London. It affects the regulation of pressure.

Pump Issues Pumps that are not functioning correctly can raise pressure in the system.

Trapped air can disrupt the water flow and cause the pressure gauge to go up.

If you're not certain about the reason, it is always best to speak with a certified engineer who can provide an expert London Boiler Service.

How to Reduce Boiler Pressure - Step-by-Step Guide

If you notice that your pressure reading has been consistently high, you should follow these guidelines to decrease the pressure:

1. Turn Off the Boiler

Before you do anything, switch off your boiler and let it fully cool.

2. Bleed Your Radiators

Use a radiator key to remove water and air from your radiators. This will help remove pressure from the system. Be sure to bring the appropriate container, either a small cloth or a rag, to collect any water.

3. Check the Filling Loop

Make sure the valves for filling loops are closed completely. If they're not closed, the water will continue to enter the system, increasing the pressure.

4. Release Excess Water

Specific systems permit manual drainage via the drain-off valve. This is only recommended when you're comfortable working with boiler systems.

5. Monitor the Pressure

Restart the boiler and monitor the pressure gauge when the pressure is lower. A bigger problem could be at hand if the pressure increases fast enough.
