2. Solutions to the problem of underfloor heating
In response to the above problems, we have compiled the following solutions:
1. Solutions to clogged pipes
Regular cleaning of floor heating pipes is key to preventing blockages. It is recommended to carry out professional cleaning every 2-3 years, using pulse cleaning or chemical cleaning. If you find that the local area is not hot, you can try to close other circuits and flush the problem pipes separately.
2. Solutions to insufficient water pressure
Check the manifold pressure gauge, the normal pressure should be between 1.5-2bar. If the pressure is insufficient, water can be replenished manually through the water replenishment valve. Note that you need to operate slowly when replenishing water to avoid air intake into the system.
3. Solution to thermostat failure
First check whether the thermostat battery is exhausted, and secondly confirm whether the temperature sensor is working properly. If the problem persists, it is recommended to contact a professional to repair or replace the thermostat.
4. Solution to system not exhausting
The exhaust operation is performed through the exhaust valve on the water distributor. The specific steps are: close all circuits and open the exhaust one by one until clean water flows out without bubbles. It is recommended to use a container to collect water when exhausting to avoid getting the ground wet.
