What causes air in central heating system?
Why Air Builds Up In Central Heating Radiators Air can build up in radiators as a result of installing the pump above the supply tank. There can be an accumulation of hydrogen in the system as a result of rust within piping or the development of too much sludge. Leaks are often a cause for air build-up.
How do you get rid of an airlock?
