If you have radiant in-floor heating in your home, you know how wonderful it can be on a cold winter day. But what do you do when your radiant in-floor heating stops working?

Here are seven possible reasons why your radiant in-floor heating isn’t working:

1. Faulty Thermostat

The thermostat is the most important part of your radiant in-floor heating system. If the thermostat is not working properly, the system will not be able to maintain a consistent temperature. There are a few things that can cause a thermostat to malfunction, such as a loose wire or a faulty sensor. If you think that your thermostat is the problem, you should call a qualified technician to come and take a look at it.

2. Insufficient Insulation

If your radiant in-floor heating system is not properly insulated, it will not be able to maintain a consistent temperature. This can be a big problem in colder climates where the ground can freeze. Make sure that your system is properly insulated by using high-quality insulation material.

3. Damaged Cables

If the cables that run to your radiant in-floor heating system are damaged, the system will not be able to function properly. These cables can become damaged by animals, weather, or simply age. If you think that your cables are damaged, you should call a qualified technician to come and take a look at them.

4. Defective Heating Mat

If your radiant in-floor heating isn’t working, another possible reason is a defective heating mat. A defective heating mat can cause the heating system to overheat or not heat up at all. If the mat is defective, it may need to be replaced.

5. Damaged Zone Valves

If your floor has multiple zones, each with its own thermostat, the problem may be with the zone valves. If a valve is damaged, it may not be opening or closing properly, which can cause the floor in that zone to be too hot or too cold.

6. Air Lock

The radiant in-floor heating system is filled with water, and this could create an airlock. This happens when the water level drops and the pump doesn’t have enough water to run. This could be due to the fact that you have a leak somewhere in your system.

To fix this, you will need to find the leak and repair it. You will also need to bleed the air out of the system. This can be done by opening the bleeder valves and letting the air out.

7. Incorrect Installation

Radiant in-floor heating is a complex system, and incorrect installation can lead to several problems. Hiring a qualified contractor is essential.

Conclusion

There are several reasons why your radiant in-floor heating may not be working. These include thermostat issues, incorrect installation, and leaks. If you're experiencing any of these problems, it's important to contact a professional to help you troubleshoot and repair the issue. With proper care and maintenance, your radiant in-floor heating can provide years of comfortable, efficient heating for your home.
