Why is my underfloor heating not working in one room?
One of the most common complaints we receive from the London residents is their underfloor heating does not work properly in one room while the rest of the house feels warm.
Like every other heating system, underfloor heating systems do get damaged as well. From trapped air to damaged pipes, there are literally a number of reasons that can stop your underfloor heating system from working efficiently.
Sometimes the problem starts slowly where one room takes longer to warm up compared to other areas within the house. Also in some properties, the floor may still feel slightly warm but takes a long time to warm the room.

First, let’s look at the few potential causes behind an underfloor heating not working in one room, and the reason behind it. We will also reveal some easy tricks to fix minor issues as well.
Underfloor Heating Problems
If a single zone or a specific room is not heating up, it could be caused by a number of underfloor heating problems as stated below.
Common Causes Of Underfloor Heating System Failure
- Trapped Air
A wet underfloor heating system can develop air locks, stopping hot water circulation in a specific area.
- Faulty Thermostat
This is quite common in older thermostats, where it may stop sending the correct signal to open heating zone in a specific area
- Actuator Valve Failure
The actuator on the manifold controls water flow to each room. If the actuator valve is damaged, the water flow is disconnected from reaching every room.
- Low Pressure
Low heating system pressure can prevent boiler circulation in different locations within your property
- Pump Failure
Damaged circulation pumps may not push enough water in underfloor heating system for circulation. This is usually noticeable only during winter season or during heavy usage.
- Damaged Insulation
Poor or damaged insulation can make one area feel more warm and other area feel colder
- Electric Underfloor Heating Cable Failure
In electric underfloor heating system, a damaged heating mat or failed heating sensors can isolate specific areas from getting warmer
- Trapped Air
DIY Fixes You Can Try Before Calling Our Engineer
Before calling our engineer, here are some quick checks you can do;
- Check Thermostat Settings
Make sure the thermostat is not damaged and set to heating mode and it’s temperature is higher than the current room temperature.
- Restart the heating system
Turn off the boiler and underfloor heating system for 3 – 5 minutes before restarting. This helps reset the temporary heating circulation faults.
- Bleed Trapped Air
For wet underfloor heating system, bleeding trapped air can fix the temperature circulation problem
- Flush Dust From Thermostat Vents
It’s a rare case. When dust builds up inside the thermostat vent, it can affect temperature readings and system response.
DIY fixes usually work only for the minor issues, however if there is a major issue, it’s time to call our engineer before it causes further damage and increases the cost of underfloor heating services or underfloor heating repair.
