What Happens When Your Boiler Loses Pressure?

4.1Many things can go wrong with boilers. A boiler is a complicated, sophisticated piece of household equipment and there are many issues that can cause a boiler to stop working, or to work less well than it should. One of the most common reasons for a boiler to develop problems concerns the water pressure. If you notice your boiler losing pressure, what should you do? Is there are way of fixing the drop in pressure? Do you need a London heating engineer to sort out the problem?

A Guide to Boiler Water Pressure

It is easy to check the pressure on a modern boiler as there is a pressure gauge on the outside of the boiler casing that you can read. If you are unsure where it is, look at the boiler manual which will tell you. You can read the pressure on the gauge and compare it to the ideal pressure, which will also be listed in the manual. A good level of water pressure is essential for the boiler to work properly.

What Causes Low Water Pressure in a Boiler?

There are a variety of causes of a drop in water pressure. One common reason for pressure to drop is a leak – the leak could be in the boiler itself, or in the central heating system such as the radiators. If the radiators have recently been bled then this could be causing the drop in pressure. It is a good idea to keep an eye on the pressure gauge over a period of time and see if the pressure goes up and down.

What Can You Do?

Some boilers allow you to manually adjust the pressure, and this will be detailed in the boiler manual. Or there will be details on the boiler casing. If you can follow the instructions to fix the water pressure, do so. By fixing any leaks in the radiators and fixing the pressure gauge you can solve the problem. But if the issue persists, contact a heating engineer. If you need to remove the cover of the boiler to reset the pressure, leave this task to the professionals. It is dangerous to remove components of the boiler and it can result in a damaged boiler and a dangerous central heating system. Pressure drops can be easily fixed by an experienced engineer.

Do You Need a New Boiler?

Often the water pressure issue can be easily fixed. But with some older boilers the problem does not go away, and a replacement boiler is the only answer. When it comes to boiler installation London has many different options. Choose a registered and professional installer to handle your boiler installation because a new boiler is a big investment. London plumbers and heating engineers should be able to help you decide which boiler is right for you. A range of different modern boilers are available to give you good options for conserving water and benefiting from a cost-effective and efficient heating system.
