An airlock in a vented hot water system is a blockage caused by trapped air within the pipework, preventing hot water from flowing properly. According to information, airlocks happen when air is trapped in the system. This air forms a blockage which gets in the way of the hot water as it makes its way to the taps or the central heating system. An airlock in the hot water system will prevent water from coming out of the affected tap.
Here's a breakdown:
- Cause: Trapped air in the pipes.
- Effect: An obstruction that stops or reduces water flow.
- Symptom: No water, or reduced water flow, from a specific tap or radiator.
In essence, the air bubble creates a pressure imbalance, hindering the water from circulating as it should. This typically impacts a specific part of the system, such as a single tap or radiator.
