Aberdare CF44: electric underfloor heating not working
Electric underfloor heating not working here means an inspection, a set of readings and a scope you can check line by line. Covers electric underfloor heating not working across Aberdare and the surrounding CF44 postcodes.
Do this before we arrive
- Worth planning for: check the board for a tripped device on the heating circuit before assuming the mat has failed.
- Confirm the thermostat is actually calling for heat — set point well above room temperature, and check any holiday or timer mode. Worth knowing before booking.
- In our experience locally, note when it last worked and whether any flooring, plumbing or joinery work happened around then.
While you wait: underfloor heating circuits require RCD protection, and a mat that fails insulation resistance testing must not be energised again until it has been repaired or isolated permanently.
There is a short version and a long version of electric underfloor heating not working. The short version: test it, then decide.
Timescales are given honestly. If a part has to come, we say when rather than leaving it open. In practice that means checking a failed floor sensor reading before anything is replaced.
Aberdare properties near Merthyr Tydfil are covered on the same schedule, so a joint visit is often possible if a neighbour needs the same thing. It is written into the report either way, so nothing is hidden.
We would rather turn a Aberdare job down than take on something we cannot certificate honestly. Anyone testing properly will reach the same conclusion.
Where previous work has no certification behind it, we test it rather than take it on trust. It rarely changes the price, but it does change the plan.
Local housing here is largely ex-mining cottages in Trecynon and Cwmbach, and that shapes both the likely findings and the realistic scope. We would rather rule out a failed floor sensor reading early than discover it late.
If a part needs ordering, you will know the timescale before we leave. Every reading we take is on the report, so a second opinion can check our work.
Written for Aberdare property owners rather than as general advice.
What we expect to find
- Frequently reported from CF44: a thermostat at end of life, or one whose.
- A tripped RCD or RCBO on the heating circuit — cheap to confirm with instruments, expensive to assume.
- Weather and exposure play a part locally, and physical damage to the mat, typically from a fixing is the usual result.
- A failed floor sensor reading open or short circuit, which explains why the problem comes and goes rather than staying put.
Our method on the day
- That sequence tells us in minutes whether you are. That covers the part most people are unsure about.
- We measure the mat's resistance and insulation resistance against — no shortcuts, because the paperwork has to stand up.
- That sequence tells us in minutes whether you are. Nothing gets replaced on a hunch.
As with every job in CF44: mat, sensor and thermostat testing quoted as a single diagnostic visit; parts and repair priced after readings.
Why this comes up in Aberdare
Older Aberdare cottages frequently lack RCD protection on any circuit, meaning a consumer unit upgrade is almost always the first remedial after an EICR.
Aberdare is roughly 22 miles from Cardiff, well inside the area we cover daily.
We are in Aberdare most weeks, and in Merthyr Tydfil, Mountain Ash, Pontypridd nearly as often.
Questions we get asked
Can I use my own materials?
If they are suitable and certified, yes. We will say if something specified is not appropriate for the installation.
How long does a visit usually take?
It depends on circuit count and access. We give a time estimate for the Aberdare address when the job is booked rather than afterwards.
What should I have ready before you arrive?
Access to the board and to the affected area, plus any previous certificates. That is enough to start at the Aberdare property.
Do you offer scheduled repeat visits?
Yes. Where an installation needs periodic checks we diary it rather than leaving you to remember.
How quickly can you get to Aberdare?
We come in via the A4059 linking to the A465, and Aberdare is on our regular round, so we normally offer a slot within a few days.

Send a short description and any previous certificate. We will say what testing is needed before we quote anything. We hold Aberdare slots for electric underfloor heating not working most weeks.
