DiscreteHeat UK, Thermaskirt Opiniones 

On the 8 October 2025, we had our ThermaSkirt system installed by one of DiscreteHeat's recommended installers in 3 of our upstairs rooms (our home was built in 2021).

The designs supplied to us by DiscreteHeat was followed nicely as far as we can tell. However, after running the system for 3 to 4 months, we started hearing extremely loud (imagine a gunshot) clicks as the skirting boards heated up/cooled down. This was rather frustrating as the whole project costed us about £4500 (to remove radiators, install thermaskirt, commission thermaskirt), and we can no longer reinstall our radiators.

Since this noise would wake us up every dawn as the heating turned on to heat up the rooms by the morning, we had to fully disable our upstairs heating for the nights.

After more than 4 months of chasing DiscreteHeat about this issue, we were told that they had found out that one of their suppliers used the wrong plastic while making the section our capping had been attached to, so they agreed to come out and replace it at the end of July 2026. Naturally, as this change has happened in the summer, we could not fully stress-test the system, but I did 1 heat cycle and the clicking was gone.

Unfortunately as October hit, we had to start using our heating more and more, and quickly the clicks resurfaced (although a bit quieter this time, but still enough to wake up every living soul). We tried to lower down our flow temperature to 30C from 35C (we keep 18C-20C room temperatures), but that also didn't help.

I immediately contacted DiscreteHeat (October 25th), but they have been ignoring me entirely. I'm a bit stuck, therefore I'm hoping that going public may get to them before I try to seek out alternative routes.

Such a shame as the product concept is great, but clearly they have stuff to figure out with their thermal expansions. We'd love to keep the skirting boards as they genuinely free up so much space, and heats up the rooms very evenly. I'm happy to take sections off of the wall and try anything they would recommended, but without zero comms from them, it's difficult to find a solution that is clearly an issue with multiple customers.

Absolutely fantastic system! The physics of it (as a scientist) makes perfect sense!

Uniform heating through the room and no need for bulky radiators in narrow spaces. I have both in some rooms though.

Installation went well with installer that was recommended.

Face can be painted in RAL colours to suit the room and we added profiles to the face so that you cannot tell the difference between real skirting!

Genius system!

After an installation in June 2013 we have had 13 years of continuous service from our Thermaskirt products, they have kept a very large lounge with an underfloor void, warm all through winter. They look great with the complementary wooden skirting boards too

I have installed Discrete heating in a 3 bedroom house and I am pleased with the look and product.
There is no unsightly radiators now,just prefinished heated skirting boards that heats the whole room efficiency.The Discrete team were very helpful from start to finish for our project.

We had ThermaSkirt-e installed throughout our Cambridge 3-bedroom apartment 10 years ago. Not only did this cleverly designed and easy to install product free the wall space from the unappealing and inefficient radiators but also proved in practice to provide a rapid, pleasant, odour- free and uniform warmth in each individual room. DiscreteHeat were most helpful in calculating the amount and in the positioning of the skirting, based on our floor plans and room size, so that the right heat output would be assured.  Unlike underfloor heating, any components of the ThermaSkirt-e are easily replaceable should the need arise after prolonged or intensive use, 10 years in our case. We would highly recommend ThermaSkirt-e from DiscreteHeat - Izabela & Jeremy

We bought our property with Thermaskirt already installed throughout the entire ground floor level approximately 10 years ago. The system has been brilliant over that time, generating a lovely consistent heat and with no issues at all. Highly recommend this product as a great alternative to underfloor heating. 5 stars!

Great company and really go above and beyond!

We had our Thermaskirt heating installed 10 years ago and are extremely happy with it. It discretely heats our living room without the bulk of radiators and allowed us to keep the cottage's original floors. It has lasted 10 years without any problems. I would definitely purchase their skirting again.

We have had the system for a good ten years now and have been very pleases with the performance in an open plan kitchen lounge setting with two bi-fold doors in the garden wall. It has kept us nice and warm in the winter months

Great customer service, and a big thank you to Mitch. He was very friendly, helpful, and accommodating, answering all my questions thoroughly. Mitch also kept me regularly updated and checked in with me throughout the process, which I really appreciated. I’m looking forward to replacing all my radiators with Thermaskirt.

When I bought my home, Discrete Heat had already been installed by a third party. After experiencing a number of leaks over the past few years, I contacted DiscreteHeat directly for help.

From the outset, Martin was incredibly generous with his time and committed to getting to the bottom of the issue. Despite the problems ultimately relating to the original installation and maintenance, rather than anything DiscreteHeat had done, the team took my concerns seriously and worked with me to find a sensible long-term solution. They were also extremely fair and reasonable when it came to the cost of putting things right.

Carl and Josh were the engineers who completed the refit and did a brilliant job. Both were polite, professional and clearly took pride in their work. Everything was explained clearly, the work was completed to a very high standard, and it has given us real confidence in the system going forward. We now have a neat, reliable and efficient heating system that will give us peace of mind going forward.

A big thank you to Martin, Carl, Josh, Russell, Mitch and everyone at DiscreteHeat who helped us along the way. What could easily have remained a frustrating experience was completely turned around by the way the team handled it. Discrete Heat is a company that genuinely stands behind its product and its customers.

I had a existing discrete heat instillation which had sprung a leak on a joint. I contacted discrete heat for advice. No long hold times and the operator gave good advice and sent required spares to me the same day. System repaired up and running. Great service.

We have a daughter with severe disabilities and were quite concerned about the rdaitor in her bedroom. Some friends of our had the Thermoskirt and were really pleased with it, so we thought we would give it a go.
Im no plumber but I consider myself reasonable handy and the online videos are good and the instructions pretty clear so I thought I would fit it myself.
The copmpany has a helpline so after a couple of calls, I was confident I could manage it. In less than a day I had re-fitted the whole bedroom and it didnt even need bleeding. Plus the tatty skirtings were replaced and new as well
Its a great system and I am planning on doing more.

We have had ThermaSkirt for 16 years and it has been brilliant. Replace all the radiators in Living Room,bedroom and Kitchen which freed up a lot of dead space which the radiators took up .the apartment is warm and cozy with no cold spots anywhere. Best heating decision we ever made."would highly recommend

Had it installed 2 years ago, the process was seamless went through all my plans to delivery to installation.

The installers were so polite as well, ran through everything they was doing and even tidied up after themselves!

Just had it fitted in my new house; I had it first time around 15 years ago in my consevatory. Never missed a beat but the new stuff is even better. Glad to get rid of some radiators. Nice lads that fitted it too; and made in the UK!

Great service from the team, and Mitch was on hand to help with any queries we had.
We ordered the electric skirting to fit around our room, and they were very helpful in suggesting installers and providing the extra information our electrician needed, which helped greatly.
The product is great, and it frees up the space the radiators used to take.

Great company, I had what I thought was a missing part, it turned out I hadn't, my fault, I didn't read the label properly. They were very helpful and even offered to send me a replacement.
Looking forward to installing the system, but if I have any problems I know I can call them and they would talk me through it.

From the initial enquiry through the design process and amendments to ultimately the delivery and after sales support, the responsiveness, clarity of communication and general service was all exceptional.

Would highly recommend them and the electric skirting board products.

I would advise caution before using DiscreteHeat.

I paid DiscreteHeat £3,252.67 for the supply and installation of a ThermaSkirt heating system. My contract and payment were with DiscreteHeat; I did not appoint or pay the subcontractor they sent.

The installation on 1–2 September 2025 was left unfinished and caused damage to new flooring and walls, a leak, poor finishing and problems with the thermostat/control setup. I complained immediately.

Despite my contract being with DiscreteHeat, I was largely left dealing with their subcontractor, Joshua James G. from IHSTHERMA. Between 2 and 17 September, I sent repeated follow-ups. DiscreteHeat did not substantively respond for 16 days; replies came mainly from the subcontractor, who changed proposed dates and disputed responsibility.

On 17 September, with the problems still unresolved, I formally warned DiscreteHeat that I would dispute/revoke the £3,252 payment through my bank. Managing Director Martin Wadsworth responded the following morning, 18 September.

When the problems remained unresolved, I raised a Section 75 claim with my card provider. The transaction was ultimately credited back.

After returning from holiday, it took around three days for the system to bring our two-bedroom flat back to only around 20°C. It produced persistent cracking noises during operation. This was particularly concerning because it had been sold to me as the primary heating solution.

On 3 February 2026, I received an email stating that I had “effectively obtained goods by deception.” The following day, I was told “You cannot have your cake and eat it,” warned about court proceedings and additional legal costs, and told I was “proceeding at your own risk.” DiscreteHeat also stated that “we have advised our network of approved installers of our dispute.”

I found this particularly pressuring because the installation and property damage remained unresolved. I was also being asked to allow the heating system to be removed in the middle of winter, leaving the flat without that heating system. Rather than focusing on resolving the installation and damage, I felt pressured to pay or settle to avoid that situation and further legal action.

By 13 February 2026, DiscreteHeat confirmed that a Small Claims claim had been filed.

During the proceedings, Joshua’s team turned up at my home without notice while I was not there. Joshua later described this as “an informal courtesy call.” To me, this felt less like a genuine attempt to resolve the matter and more like an effort to create a paper trail showing engagement during the court case.

Publicly available company records showed that DiscreteHeat/Thermaskirt sent a subcontractor, Ihsterma, whose company had been incorporated only around five months earlier. The director had also previously been associated with MULTIPLE dissolved companies, some with relatively short trading histories. This does not in itself establish wrongdoing, but it raised legitimate concerns for me about due diligence, continuity and accountability if something went wrong.

The dispute was ultimately settled and the system removed. By that stage, we felt we had to use a body camera during the removal so we would have a clear record if any further damage occurred. DiscreteHeat had disputed responsibility for the previous property damage, and we had already paid for those repairs ourselves.

What should have been a straightforward installation became months of property damage, incomplete work, poor heating performance, cracking noises, repeated chasing, a bank dispute, accusatory emails and Small Claims Court proceedings.

Keep close attention to the very small grey print on DiscreteHeat’s quotation or invoice, particularly the statement that its heat-loss calculations “do not form part of a performance guarantee” and that the assumptions “have not been independently verified by DiscreteHeat Co Ltd.

My advice: get an independent heat-loss assessment, confirm responsibility for remedial work in writing, check the installer and its directors, photograph the property BEFORE work starts, and use a payment method with strong consumer protection.

Based on my documented experience, I would not use DiscreteHeat again and could not recommend them.
