How to Check Your Combi Boiler Water Pressure

Understanding Combi Boiler Water Pressure

Maintaining the correct water pressure in your combi boiler is essential. It ensures the boiler runs efficiently and safely. If the pressure is too low or too high, it can cause problems. This guide will help you check and adjust your combi boiler's water pressure.

What You Need

Before you start, gather a few tools. You might need a pressure gauge, a filling loop, and a manual. These items will help you measure and adjust the water pressure.

Next Steps

• Locate the pressure gauge: Find the pressure gauge on your boiler. It's usually on the front panel.
• Read the pressure: The gauge should show a pressure between 1 and 2 bars when the boiler is off. If it's outside this range, you need to adjust it.

Adjusting Low Water Pressure

If the pressure is too low, you can increase it. Here's how:

• Find the filling loop: This is a flexible hose connected to your boiler.
• Open the valves: Slowly open the valves on the filling loop. Watch the pressure gauge.
• Close the valves: When the pressure reaches 1 to 2 bars, close the valves.

Find a radiator bleed valve in your home.

• Release water: Use a bleed key to release water until the pressure drops to the normal range.

  

Regular Maintenance

Regularly checking and adjusting your boiler's water pressure is crucial. It ensures your heating system works efficiently. If you're unsure or uncomfortable doing this, contact a professional. They can help maintain your boiler safely.
