And remember, if you're unable to fix the problem yourself, our team of experienced professionals is just a phone call away.


Understanding Boiler Pressure

Boiler pressure refers to the balance of water and air within the heating system. A drop in pressure can indicate various issues, ranging from minor leaks to more significant malfunctions. It's essential to address pressure drops promptly to ensure your boiler operates efficiently and safely.


Signs of a Pressure Drop

  1. Cold Radiators: If your radiators feel cold or only partially heat up, it could be due to low boiler pressure.

  2. Visible Leaks: Check around your boiler and heating system for any signs of water leakage, which may contribute to pressure loss.

  3. Loss of Hot Water: A drop in pressure can affect the delivery of hot water to your taps and showers, leading to inconsistent water temperature.

Steps to Resolve a Pressure Drop

  1. Check Pressure Gauge: Start by checking your boiler's pressure gauge. If it's below the recommended range (usually between 1 and 1.5 bar), you'll need to repressurise the system.

  2. Repressurise the Boiler: Most modern boilers have a filling loop that allows you to add water to the system. Follow the manufacturer's instructions to repressurise the boiler carefully.

  3. Inspect for Leaks: Once the pressure is restored, inspect your boiler and heating system for any signs of leaks. Common areas to check include radiator valves, pipework, and the boiler itself.

  4. Bleed Radiators: Air trapped in your radiators can also contribute to pressure drops. Bleed each radiator using a radiator key to release any trapped air and restore proper circulation.
