## Summary description

Santech QHeat5 heat meter (model QH5K-000-00-0) is a compact DN15 calorimeter with nominal flow qp 1.5 m3/h, designed to measure thermal energy consumption in heating systems. Provided with a zasilanie (power) variant, it records heat via temperature difference and volume flow for billing, monitoring and energy management in residential or small commercial applications.

## Long description

Santech QHeat5 qp 1.5 m3/h DN15 (model QH5K-000-00-0, power variant) is a compact heat meter designed to measure thermal energy consumption in heating systems. The device determines heat by measuring the volume flow through a DN15 pipe combined with the temperature difference between supply and return lines. Its small footprint and nominal flow rate make it suitable for domestic and small commercial installations where accurate recording of energy consumption is required for billing, monitoring and energy management.
Advantages
The Santech QHeat5 provides reliable heat measurement through integrated flow and temperature sensors, delivering consistent data for consumption accounting. Its DN15 size and qp 1.5 m3/h nominal flow offer compatibility with typical residential heating circuits. The meter’s compact construction facilitates installation in confined plant rooms or meter cupboards, while the power variant ensures continuous operation and stable data transmission when integrated with building energy management systems.
Suitable for
Individual apartments and houses with central or local heating circuits
Small commercial premises and offices requiring local heat submetering
Energy billing and consumption monitoring in retrofit or new installations
Applications where space is limited and a DN15 connection is required
Key specifications
Pipe connection size: DN15
Nominal flow (qp): 1.5 m3/h
Measurement principle: volumetric flow combined with supply/return temperature differential
Application: thermal energy measurement for heating systems
Installation position: inline in heating circuit (compact body for confined spaces)
How to use
Install the heat meter inline on the supply or return pipe of the heating circuit following system hydraulics and orientation markings on the body. Ensure proper thermal insulation of pipework and avoid flow disturbances by maintaining straight pipe lengths as recommended by the manufacturer before and after the meter. Connect the power supply and any required communication wiring according to installation guidelines to enable continuous measurement and data readout. Commission the device by confirming zero flow readings at rest and checking temperature sensor response under operating conditions.
Usage recommendations
For accurate and long-term measurement, ensure regular inspection of the installation for leaks, correct insulation of pipes, and stable power supply. Follow local metering and billing regulations when using the meter for consumption accounting, and consider periodic verification or calibration according to applicable standards.
