How we repair your Radiant Floor Heating System
A radiant floor heating system warms rooms from the floor up using hot water tubing or electric heating cables installed under the floor surface. A radiant floor heating system relies on a heat source, safety controls such as limit switches and flame sensors, blowers or circulator pumps, and a thermostat. A technician checks the ignition and safety sequence, airflow or water flow, and electrical controls.

Common Radiant Floor Heating System problems we fix
What usually causes each symptom, and what our technician checks to confirm it.
One zone not heating
- Likely causes
- A failed zone valve or actuator, a bad zone thermostat, or air locked in that loop.
- What our technician checks
- The technician tests the thermostat call, actuator operation and loop flow at the manifold.
Floor takes very long to warm up
- Likely causes
- Low supply water temperature, a failed mixing valve, or a circulator that is too weak.
- What our technician checks
- Supply and return temperatures are measured and the mixing valve and circulator are tested.
Cold spots in the floor
- Likely causes
- Air in a loop, a balancing valve set too low, or a damaged tube or cable section.
- What our technician checks
- Loops are balanced and purged, and an infrared camera is used to locate cold areas.
Electric floor heat not working
- Likely causes
- A tripped GFCI in the thermostat, a failed floor sensor, or a damaged heating cable.
- What our technician checks
- The GFCI and thermostat are tested, sensor resistance is checked, and cable resistance and insulation are measured.
Floor too hot
- Likely causes
- A stuck mixing valve sending full boiler temperature to the floor, or a failed floor sensor.
- What our technician checks
- Mixing valve operation and floor sensor readings are checked against setpoints.
Pressure dropping in hydronic system
- Likely causes
- A leaking manifold fitting, a failed expansion tank, or a relief valve discharging.
- What our technician checks
- Manifold connections are inspected and the system is pressure tested.
Quick checks you can do safely
- Check the zone thermostat setting and batteries.
- Press the test and reset button on an electric floor thermostat.
- Look at the manifold pressure gauge on hydronic systems.
- Confirm the boiler or water heater feeding the system is running.
- Allow several hours for the floor to respond after changing the setting.
Safety first: Never drill or nail into a heated floor without locating the tubing or cable, and electric systems must stay GFCI protected.
