Underfloor Heating


If your underfloor heating doesn't seem to be working correctly, we’ve probably got it covered in this “tricks and tips” blog post. If not, let us know and we’ll add it.

If you can’t get your underfloor heating working after these checks, get in touch with us at AHP Boiler Services to get back up and running asap.

So, read through our suggestions below, using the manifold diagram to familiarise yourself with the components we are going to be dealing with.

Underfloor Heating Manifold


Underfloor Heating Manifold 


This is where all the underfloor heating distribution to rooms takes place

Get Your Underfloor Heating Working with these 5 Tips:


Underfloor Heating Problem 1: Thermostats


ThermostatsIs the room thermostat on and calling for heat? Make sure it’s set above the current room temperature. Make sure the flame is showing a call for heat.

If not, this could be the problem.

Underfloor heating Problem 2: Flow Valves


Flow ValvesAre the flow valves on the Manifold (illustrated in the manifold diagram above) showing flow movement? Are the red stoppers twitching up and down due to water movement?

If not, this could mean mechanical failure. Don't worry though, this can be easily rectified by our qualified engineers..


Underfloor Heating Problem 3: Actuator Flow


Actuator FlowAre the actuators (illustrated in the manifold diagram above) allowing the central heating water to flow around the underfloor piping? If you can see the the blue round top lifting up or it is up like in this picture its open and the water should be flowing through.

If not, there’s a possible problem with this. You can temporarily remove this actuator head so you can get it working until the engineer gets there.


Underfloor Heating Problem 4: Pump is Running


Pump is runnyMake sure the water pump is running by touching to feel if it’s oscillating.

If no, this could mean mechanical failure.And you will need to call an engineer to repair.

Underfloor Heating Problem 5: Trapped Air


Trapped AirFinally, check that there is no air in the under floor heating circuit by bleeding the air out. Check the manifold, there will be an air bleed valve for you to use (as illustrated in the manifold diagram above)
