How to Fill Your Ideal Combination Boiler
Low boiler pressure can stop your boiler from functioning correctly. If your pressure gauge reads below 1 bar, it might need topping up. However, incorrect filling can lead to over-pressurisation or leaks.
Common Mistakes When Filling a Boiler:
- Overfilling, causing pressure to reach the red zone
- Not securing filling keys or valves properly, leading to leaks
- Ignoring trapped air, which can cause noises and uneven heating
Why Choose a Professional Service?
We recommend having a professional show you the correct way to fill your boiler. Our engineers can guide you through the process, ensuring safe operation and avoiding costly damage.
