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

What should I do if there is no hot water in the floor heating?

Cause of failureSymptomsSolution
Boiler does not startThere 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 lowThe pressure gauge shows less than 1 barPressurize to 1.5-2bar through the water replenishment valve
Circulation pump failureThe water pump does not run or makes abnormal noisesClean the impurities in the pump or contact after-sales service for replacement.
Pipeline blockedSome rooms are not hot or have large temperature differencesClean the filter or contact professional floor heating cleaning
Thermostat failureNo response to set temperatureReplace 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.
