Boilers are expensive and complicated pieces of equipment that you really don’t want breaking down. Even expensive, reliable boilers end up giving you cold water occasionally, which can be a nightmare in the middle of winter. However, you do not need to buy a new boiler every single time you have got an issue with yours. Heck, you don’t even need to call a professional in half of the time. If you are having problems with your boiler, and the hot water is not working, then there’s a good chance that loss of water pressure might be to blame. If this is the case, don’t worry! It’s fairly easy to sort out without the need for a professional to visit your house. Your water pressure must be stable if you want your boiler to effectively push heated water through your system of pipes. If your boiler does end up experiencing a loss in pressure, here are some easy steps to follow:
- First, check the boiler pressure
It’s usually a very simple process to find out the water pressure of your boiler. On most boilers, there is a water pressure gauge located on the front of your boiler. If you’ve got a hydraulic pressure gauge, then high and low pressure should be indicated on red sections of the dial. Often, there is a red needle which will depict the pressure set when the boiler was first installed. This will help you to know whether there has been an increase or decrease in pressure. On digital gauges, you’ll usually see a flashing pressure warning if there is excessively low or excessively high pressure.
- Understand what the pressure indicators mean
It’s extremely important to understand what signifies high pressure, and what signifies low pressure. While this may sound obvious, it is a key aspect to fixing your boiler issues. If your boiler pressure is less than 1 bar, then you are experiencing low pressure. If your pressure is greater than 2.75 bar, then you’re experiencing high pressure. High pressure is best resolved by an engineer.
- If your boiler has low pressure, follow these steps
In order to repressurise your boiler, you’ll have to allow more water to enter the system through the filling loop. Each boiler works slightly differently, meaning that it’s always best to check the boiler manual before doing this yourself. However, with most boilers, you’ll want to follow a similar process to this:
- First, switch your boiler off and allow it to cool down.
- Ensure that the two ends of the filling loop are fully attached.
- Open both valves to allow water into the boiler system.
- Wait for the boiler to reach 1.5 bar pressure, before closing the valves individually.
- Turn the boiler back on.
- Undo the ends of the filling loop, before removing the filling loop.
If, after reading the boiler manual and the steps above, you’re still confused about repressurising your boiler system, then it may be a good idea to call a professional. Be sure to check out Boiler Repair and Installation in Southampton from EcoSafe if you’re in the area.
