The pressure will naturally increase when the boiler is on so, if you're adding water to the system while the heating is off, don't add too much. When repressurising your boiler, it's important to keep an eye on the pressure gauge so that you know when you've added the right amount of water.

A combi boiler's pressure gauge is typically found on the front of the appliance and should sit comfortably between 1 and 1.5 bar of pressure (or the green section). This level should be maintained and checked regularly in order for the central heating system to work efficiently throughout the year.

26/4/2021 · What the hell is boiler pressure and why do you need boiler pressure? Boiler pressure is simply the balance of water and air within your boilers sealed system. In order to function correctly, your boiler needs a particular balance of water and air to ensure the pressure in the system is adequate for when water is demanded from the boiler – essentially when you switch on your heating or hot

This is where that filling loop (or filling link) comes in again! If the pressure gauge on your boiler indicates high pressure (above 2.75 bar), then you may need to bleed a radiator to bring the level down to around 1.5 bar. This can be tricky and, occasionally, dangerous; due to high water temperatures.

15/6/2021 · The central heating system is sealed (closed) and pressurised, usually to between 1 and 1.5 bar (cold). This pressure is the boiler pressure. When the system heats up, the water expands, taking up more space. The boiler pressure will rise a little, normally by up to half a bar.

Boiler pressure too high? Here's why & how to reduce it
Get a quote For combi boilers specifically, the ideal pressure levels are roughly as follows: When the heating is turned off, the pressure gauge should read between 1 and 1.5 bars. When the heating is switched on, the pressure should ideally be around 2 bars. As mentioned, any number of small issues may cause fluctuations in boiler pressure which can go

26/5/2021 · A combi boiler pressure gauge reading over the 1.5 mark whilst the heating is in full operation, is likely normal due to the water demand being placed on the boiler so it's likely nothing to worry about. In this instance, a reading between 1.5 – 2.5 bar can be considered normal. A consistent 3 – 4 bar, however, is something to raise with

Boiler pressure is high when heating is on. A slightly higher reading while your boiler is in operation is normal due to the water demand being paced on the system. So, something nearer the 2 mark is nothing to worry about. However, if something between 3-4 is your usual operation pressure then you should raise this with a professional engineer
