## Long description

Santech QHeat5 qp 2.5 m3/h DN20 — powered unit is a heat meter intended for measuring thermal energy in hot-water hydronic systems. The device records volumetric flow and calculates energy consumption by combining flow measurement with temperature difference readings. With a nominal flow rate (qp) of 2.5 m3/h and a DN20 connection size, the unit is designed for residential and small commercial heating circuits where continuous powered operation and accurate energy accounting are required.
Advantages
The powered Santech QHeat5 offers stable measurement accuracy over a range of flow rates and temperatures and supports reliable energy calculation for billing and monitoring. Its DN20 compact connection and qp 2.5 m3/h rating make it suitable for retrofit and new installations in smaller systems. The powered operation ensures consistent sensor performance and data availability for diagnostics and consumption analysis.
Suitable for
 Residential heating systems with single or multiple heating circuits
 Small commercial buildings and offices requiring heat consumption metering
 Retrofit projects where DN20 piping and qp 2.5 m3/h capacity are used
 System diagnostics and routine energy consumption monitoring
Key specifications
 Nominal flow rate (qp): 2.5 m3/h
 Connection size: DN20
 Measurement principle: volumetric flow measurement combined with temperature differential for energy calculation
 Power supply: powered unit for continuous operation
 Application: hot-water hydronic heating circuits
How to use
Install the heat meter in the supply or return pipe of the hot-water circuit using the DN20 connection, ensuring correct orientation and compliance with manufacturer instructions for straight pipe lengths upstream and downstream if required. Connect the unit to the appropriate power source and link temperature sensors as specified. After installation, verify zero-flow calibration and run initial checks to confirm correct flow and temperature readings. Use the meter’s interface or external readout system to obtain energy consumption values and monitor ongoing performance.
Usage recommendations
Place the meter where flow conditions are stable and accessible for service. Maintain filtration upstream to prevent particle ingress, follow recommended installation straight-run distances, and schedule periodic verification and calibration to preserve measurement accuracy.
