Underfloor heating systems that don't heat up can be caused by a variety of reasons, and here are some common causes of failure and how to fix them.
1. Check the heating system
1. The problem of heating source
1) Gas wall-hung boiler: Confirm whether the furnace fire is normal, whether the gas pressure is sufficient, and whether the combustion is sufficient.
2) Electric boilers: Check whether the power supply is connected, whether the fuse is tripped, and whether the device is working properly.
3) Heat pump or ** heating: Confirm that the heat pump is running and that the heating system has started heating.
2. Heating pipelines
1) Water pump work: Check whether the pump is working properly and whether there is any blockage or damage.
2) Clogged pipes: Detect whether there is a blockage in the heating pipeline, which needs to be cleaned or repaired by a professional.
2. Check the pressure of the water separator and pipeline
1. a water separator: Make sure that the separator valve is open, and there is no damage to the valve or improper adjustment.
2. Pipeline pressure: The gauge shows 4 bars which is usually the normal operating range, but make sure that the pressure is evenly distributed to each circuit.
3. Room temperature control and adjustment
1. Thermostat: Confirm that the thermostat is set correctly, whether the battery needs to be replaced, and whether it can sense the indoor temperature correctly.
2. Valve adjustmentIf part of the room is not hot, it may be that the regulating valve of the corresponding circuit needs to be adjusted.
Fourth, the system is deflated
If there is air in the system, it can lead to insufficient heat transfer. Check if system deflation is necessary.
5. System maintenance and maintenance
Regularly maintain and maintain the underfloor heating system, clean the filter, check the valves, and ensure that the system is free of water leakage.
6. Professional maintenance
If the above steps do not solve the problem, it is recommended to contact a professional repair service for system inspection and repair.
It is recommended to refer to the product manual and consider seeking help from professional technicians before any self-investigation and repair.
