Commissioning an underfloor heating system involves the final checks and adjustments necessary to ensure that the system operates efficiently and safely. Here are the general steps to commission an underfloor heating system:
- Check the system’s wiring: Ensure that all wiring connections are secure and that the wiring complies with the manufacturer’s recommendations.
- Conduct a pressure test: Test the system for leaks and ensure that the pressure is within the manufacturer’s recommended range. This test should be performed before the final floor covering is installed.
- Turn on the system: Turn on the underfloor heating system and check that the boiler or heat source is supplying heat to the system.
- Check the flow rate: Ensure that the flow rate of the heating fluid through the pipes is within the manufacturer’s recommended range. Adjust the flow rate as necessary.
- Check the temperature: Monitor the temperature of the water circulating through the underfloor heating system and ensure that it is within the recommended range.
- Adjust the controls: Adjust the system controls, such as thermostats, timers, and valves, to ensure that the system operates efficiently and that the temperature is maintained at the desired level.
- Record the commissioning results: Keep a record of the commissioning process, including the system settings, flow rates, temperatures, and any adjustments made.
It is important to follow the manufacturer’s guidelines on any materials used for commissioning and to seek professional advice if you are unsure about any aspect of the process.
Commissioning a wet underfloor heating
Commissioning a wet underfloor heating system typically involves gradually increasing the temperature of the water flowing through the pipes, to allow the system to warm up slowly and avoid any damage to the components.
While there is no fixed rule for how much the temperature should be increased each day, a common guideline is to raise it by around 5 degrees Celsius per day until it reaches the desired operating temperature. This allows the system to gradually adjust and reach its maximum performance without putting undue stress on the components.
It’s important to follow the manufacturer’s guidelines on materials used, and recommendations for commissioning and operating your specific underfloor heating system, as the optimal temperature increase rate may vary depending on the system’s design, materials, and other factors.
