Boiler Flow Meter: Efficient DHW Control
The boiler flow meter plays a critical role in modern heating systems by detecting the demand for domestic hot water (DHW) with precision. Unlike older models that relied on flow switches, this advanced component improves efficiency, reduces energy waste, and ensures stable water temperature. Learn how the flow meter optimizes boiler performance and why keeping it in good condition is essential.
The Flow Meter is, therefore, a component on the sanitary side that precisely measures the flow of water within a pipe. Malfunctions of this device can cause the boiler not to turn on during DHW extraction or to turn on when there is no demand.
The flow meter works through a sensor that detects the water flow rate using a turbine or a Hall effect meter. When water flows through the flow meter, the turbine rotates or the sensor detects the movement, sending electrical signals to the boiler’s electronic board. This board interprets the signals to regulate the flame and ensure that the amount of heat produced matches the demand for domestic hot water (DHW).
In modern models, the flow meter not only increases boiler efficiency but also helps reduce energy consumption and greenhouse gas emissions. By adjusting the flame based on the actual demand for hot water, the boiler avoids wasting energy by maintaining a high flame when not needed.
It is important to keep the flow meter in good condition to ensure the proper functioning of the boiler. A faulty flow meter can cause several issues, including:
- The boiler does not turn on when there is a demand for hot water.
- The boiler turns on even without a demand for hot water.
- Sudden changes in water temperature.
- High energy consumption and system inefficiency.
