Central Heating Boiler & Radiators


Postby jvaarkamp » Sat Apr 25, 2009 1:04 pm

Pressure is at zero on my oil fired combi boiler. How do I increase it? Also I can hear the water running around in my radiators when the heating comes on in the morning. HELP!

Google the make/model, you need to locate some sort of filling loop arrangement,or back fill it from a drain off point.Do not exceed 1.5bar

Both problems are related, increse the system pressure and all will work as normal.

Look for two valves and a braided hose, or there may be an integral fill loop to the boiler (read manufacturers instructions) without seeing the installation it's difficult to advise.
