When your radiant floor heating is working correctly, it provides consistent, even warmth. When it's not, the signs are usually obvious. Recognizing these red flags early can help you get the repairs you need before small issues become major problems.

Inconsistent temperatures: If you notice warm spots next to cold spots, or one room is toasty while another is chilly, it often points to a heat distribution problem like a blockage or a faulty zone control.
No heat at all: This could be something simple, like a thermostat setting, or a more serious issue like a broken boiler or an electrical short.
Strange noises from your boiler: Radiant systems are known for being quiet. Gurgling, banging, or grinding sounds often indicate air in the hydronic lines, a struggling circulator pump, or mineral buildup.
Leaks or water damage: For hydronic systems, any visible moisture or damp spots near your floors or walls require immediate attention to prevent property damage and mold growth.
Unexpectedly high utility bills: A sudden jump in heating costs can mean your system is working overtime to compensate for a malfunction, such as a component failure or a small leak.
Thermostat errors: If your thermostat displays error codes, goes blank, or ignores commands, it could be a problem with the unit itself or its connection to the heating system.

Top 5 Warning Signs Your Radiant Floor Heating Needs Repair:

Cold spots creating uneven heating across your floors
Complete loss of heat from the entire system
Unusual sounds like gurgling or banging from boiler components
Visible water damage or leaks around heated floor areas
Spiking energy bills without increased usage

Understanding Different System Types in Columbia

Columbia homes typically feature two main types of radiant floor heating, and knowing which one you have is key to proper repair.

Hydronic systems circulate heated water through flexible PEX tubing under your floors. A boiler heats the water, circulator pumps move it, and a manifold directs it to different zones. Repairs often involve these mechanical components, such as fixing the boiler, replacing pumps, or addressing leaks in the tubing. At Rehagen, we're experienced with the advantages of geothermal radiant floor heating, which pairs this comfort with geothermal efficiency.

Electric systems use electric mats or heating cables under the flooring. They are simpler to install and are often used for smaller areas. Repairs typically focus on electrical components like broken heating wires, faulty connections, sensor malfunctions, or tripped GFCI outlets. This work requires professional electrical expertise.

How Repair Needs Differ from Traditional Furnaces

Unlike traditional forced-air systems that push hot air through ductwork, radiant systems heat surfaces directly. This fundamental difference means repairs are entirely different. Instead of dealing with blower motors or clogged filters, radiant system repairs involve specialized components like boilers, manifolds, and PEX tubing or electrical mats. Accessing these components under the floor can be more complex than opening a furnace panel. The expertise needed for radiant floor heating repair in Columbia is highly specialized. According to the U.S. Department of Energy, radiant heating is often more efficient than other methods because it eliminates duct losses, potentially saving you on heating costs.

Common Radiant Heating Issues and Their Causes

With four decades of experience in Central Missouri, we've seen nearly every issue that can affect a radiant heating system. Most problems have clear causes and solutions. Understanding what goes wrong can help you know when to call for radiant floor heating repair in Columbia.

Common culprits include leaks from stressed PEX tubing, circulator pump failures, malfunctioning mixing or zone valves, air trapped in hydronic lines, and damaged electrical wiring. Faulty thermostats and damage from improper installation are also frequent issues we encounter.

Hydronic System Problems

Hydronic systems are reliable, but their moving parts can develop issues. Because of their straightforward design, problems are usually easy to spot.

Leaks from outside stress: PEX tubing is durable but not invincible. Shifting or sagging floorboards can put pressure on the pipes, causing cracks or pinhole leaks that are difficult to locate without specialized tools. Similarly, cracked stone or tile flooring can sometimes damage the tubing underneath.
Mixing valve malfunction: This component controls the water temperature. If it fails, you may get insufficient heat or overheating floors that can damage flooring materials.
Circulator pump failure: As the heart of the system, a failed pump means a complete loss of heat. Grinding or humming sounds often precede a total failure, signaling it's time for a service call.

Electric System Failures

Electric radiant systems have their own set of common problems, which are typically electrical in nature and require professional handling.

Broken heating wires: Wires can be damaged during installation or fail over time due to floor movement. A break will cause a loss of heat in a specific section or the entire system.
Faulty GFCI outlets or breakers: These safety devices shut off power when they detect a fault. Sometimes, the GFCI itself fails or becomes too sensitive, cutting power to a perfectly functional system.
Thermostat and sensor issues: The thermostat relies on a floor sensor to regulate temperature. If the sensor or its wiring fails, the system may run constantly, not at all, or cycle randomly.
Damaged heating mats: These mats are vulnerable to damage during renovations or floor installations, leading to a loss of heat in the affected area.
