Heat meter Santech QHeat5 qp 1.5 m3/h DN15 — QH5K-000-00-0 (zasilanie)

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.
