What Does the Pressure Gauge on Your Boiler Mean?
To ensure that your boiler and central heating system runs smoothly and to avoid any costly repairs it’s important for you to give your system the occasional bit of attention. Whether this is having your boiler serviced or just checking your boiler pressure and following the handy tips below.
How do I find the pressure of my central heating?
A pressure gauge can usually be found on your boiler’s control panel. This will usually be colour coded to make it easy to understand whether your central heatings pressure is correct or not. If not the usual water pressure level for a central heating system is around 1.0 and 2.0 bar although this may vary from system to system.
My central heating has low water pressure
One of the most common reasons for your central heating system not working is a lack of pressure. Pressure is integral to the functioning of your boiler and when pressure is lost, your boiler will not heat your home or water.
It is not unusual for a boiler to lose pressure over time and fall below 1 bar, when this happens it is very easy to repressurise your boiler yourself. However, if a loss of pressure becomes a frequent occurrence it can mean a leak has developed somewhere in the system and professional assistance will be needed.
Here’s a quick guide to adding pressure your central heating:
- Find the filling loop and connect the copper pipe between the taps, ensuring that the nuts are tightened.
- Fully open the first tap. Then open the second tap whilst keeping an eye on the pressure gauge.
- When the gauge reads between 1 and 2 turn both taps off.
- Disconnect the copper pipe.
My central heating has high water pressure
If the water pressure is too high it can be reduced by bleeding a radiator or draining some water out of the system. If the problem still occurs it’s best to get in contact with an expert.
