Circulation Issues

Crown boilers are known for their efficiency and durability. But sometimes, circulation issues can arise. These problems can affect the performance of your heating system. Addressing these issues promptly ensures your home stays warm and comfortable. The two most common circulation problems are pump malfunctions and air in the system.

Pump Malfunctions

A malfunctioning pump can disrupt the entire heating system. The circulating pump is responsible for moving hot water through the pipes. If it fails, the hot water won’t reach your radiators or baseboards.

• Check the power supply to the pump.
• Inspect the pump for any visible damage.
• Listen for unusual noises coming from the pump.

If you hear a grinding noise, the pump might be jammed. A humming sound could indicate that the pump is trying to work but can’t. Replacing or repairing the pump might be necessary.

Air In The System

Air trapped in the heating system can cause circulation problems. When air gets into the pipes, it creates air pockets. These pockets prevent hot water from flowing properly.

1. Bleed the radiators to remove trapped air.
2. Check the pressure gauge on the boiler.
3. Ensure the automatic air vent is functioning.

Bleeding the radiators is a simple process. Turn off the heating system and use a radiator key to open the valve. Listen for a hissing sound as the air escapes. Close the valve when water starts to come out.

Maintaining the correct pressure in the system is crucial. Low pressure can cause circulation issues. If the pressure drops, add water to the system using the filling loop. The pressure gauge should read between 1 and 1.5 bar.

Automatic air vents help to remove trapped air. Ensure these vents are not blocked. They can get clogged over time and may need cleaning or replacement.

Pressure-related Problems

Pressure-related problems can be a common issue with Crown Boilers. These issues can cause your boiler to malfunction or operate inefficiently. Understanding the causes and finding the right solutions is crucial for maintaining your boiler’s performance.
