Sometimes, the loop is built in; other times, it is external. 3. Open both valves on the filling loop carefully, usually counterclockwise. . Listen for the sound of filling.4. Keep an eye on the pressure gauge. When the pressure reaches the appropriate pressure, close both valves on the filling loop firmly.5. Turn your boiler back on. If the pressure is still low, repeat the process..If you're uncomfortable performing this task yourself, contact a Gas Safe registered engineer. Incorrectly repressurizing the system can cause damage.
What is a power flush, and do I need one for my new boiler?
A power flush is a deep cleaning of your central heating system, using specialized equipment to remove sludge, rust, and other debris that can build up over time. This buildup can restrict water flow, reduce heating efficiency, and cause damage to your boiler and other components.While not always strictly necessary with a new boiler, a power flush is often recommended, especially if you're replacing an older system. It ensures that your new boiler is installed in a clean and efficient system, maximizing its performance and lifespan. A clean system also helps reduce noise and improve heat distribution.Signs that you might need a power flush include cold spots on radiators, slow heating, frequent boiler breakdowns, or noises coming from your heating system. Discuss with your boiler installer whether a power flush is advisable for your specific situation.
