What should I do if there is no hot water for floor heating? Quick troubleshooting and solutions
The floor heating system is an important equipment for home heating in winter, but if there is no hot water, it may seriously affect the comfort of life. The following are floor heating failure problems and solutions that have been hotly discussed on the Internet in the past 10 days. They are presented in the form of structured data to help you solve the problem quickly.
1. Common reasons and solutions for no hot water in floor heating

| Cause of failure | Symptoms | Solution |
|---|---|---|
| Boiler does not start | There is no running sound from the boiler and the display screen does not light up. | Check whether the power supply and gas valve are open; restart the boiler |
| Water pressure is too low | The pressure gauge shows less than 1 bar | Pressurize to 1.5-2bar through the water replenishment valve |
| Circulation pump failure | The water pump does not run or makes abnormal noises | Clean the impurities in the pump or contact after-sales service for replacement. |
| Pipeline blocked | Some rooms are not hot or have large temperature differences | Clean the filter or contact professional floor heating cleaning |
| Thermostat failure | No response to set temperature | Replace batteries or recalibrate thermostat |
2. Step-by-step troubleshooting guide
1.Check boiler status: Confirm that the power supply and gas supply are normal, and observe whether there are fault codes (such as E1, E2, etc.) on the display screen.
2.Test water pressure: Open the pressure gauge below the boiler. If it is lower than 1 bar, water needs to be added. If it is too high, drain the water through the exhaust valve.
3.Troubleshooting circulating pump: Touch the pump body lightly to feel whether it vibrates. If it stops, check the circuit or replace the pump body.
4.Clean the filter: Close the inlet and outlet valves, remove the Y-type filter and clean impurities (recommended 1-2 times a year).
5.Reset system: Turn off the main power supply and then restart it after 5 minutes. Some electronic faults can be automatically repaired.
