Why is my boiler short cycling

HVAC

The answer to 'why is my boiler short cycling' is that your boiler is turning on and off rapidly, often within a short timeframe. This can be caused by a few common issues, such as a malfunctioning thermostat, a problem with the boiler's controls, or an imbalance in the heating system.

Short cycling can lead to increased energy costs, uneven heating, and potential damage to the boiler over time. It's important to identify and address the root cause to ensure your boiler is running efficiently and safely.
