Summarised with AI
Does it work? yes. Was it installed as I would expect, yes! The Team was professional etc The only issue was setting up the "App" yes there is an app. It is a Free open source app which means that instruction and guidance is awful and is still showing some things in Spanish "periodo". I love our underfloor heating and having a radiator free house. So for that I thank you
The engineer came and inspected my inverter, checked that it was OK and reported that there was nothing wrong with it and no further action required. All done within 1 hour.
Rayotec were prompt, efficient, friendly and at a sensible price. They replaced my faulty solar inverter with a compact modern unit which has worked well ever since. Can't fault them.
Useless firm - they don’t actually do any software repairs or reboots. And they don’t stock dataloggers or replace them. Waste of space
Highly recommend James and the Rayotec team! We had a great experience using Rayotec for our extension’s underfloor heating. James was fantastic—he helped us choose the right product and kept us informed every step of the way. The installation was top-notch. Even with 50% glass in the room, as it is an orangery, the heating works perfectly and is very fast to warm up. If you're looking for a reliable company, definitely go with Rayotec.
I recently had an installation by rayotec who were from start to finish great to work with. I had an installation in my kitchen/diner and works a dream. James the installer was very professional and on time throughout the installation. Rayotec as a company would recommend. Luiza
James is very helpful and skilled at what he does. The new underfloor heating is miles better than the Old system. Thank you so much for a great experience!
James our installer, was knowledgeable, efficient and personable. The advice given was clear and precise, James ensured that everything was clean and tidy at the end of the day. We have every intention of using Rayotec and James for future installations and wouldn’t hesitate in recommending him to anyone looking to install underfloor heating.
Commercial solar maintenance Great service! Responsive, professional and very helpful office staff and engineer. Visits supported with really comprehensive, easy to follow reports. Would definitely use again.
Have used Rayotec products in three areas. Have now had an issue with a mat under carpeting , issue was parquet floor under carpet buckled due to heat from ufh and raised carpet by two inches , been in house for 40 plus years , no issues previously with the floor ,They'd said twice b4 install that it was ok to and that they'd install on existing parquet. Now find comments on line saying Dont install on parquet !!!. We had to get carpet fitter to lift and resolve buckled wood floor , cost £70.00 , hadn't noticed heating didn't work any more . The mat was replaced. We Had to lift carpet, empty room , disconnect TV and hi fi etc. for new ufh mat. Then had to get carpet properly refitted ,another £60.00.. So , out of pocket by £130.00 Plus had to empty room for new mat. Not fun at 75 years old.. Anyway, despite an offer received to contribute £100.00 towards carpet fitters costs and giving bank details etc..Nothing received and calls not returned..
I was very happy with this company and would definitely recommend. They were very knowledgeable with good communication. I was extremely pleased with the work. The team were all very experienced and ensured it was done in the most suitable way (as it had to link into an existing system). Thank you Rayotec Team
Excellent installation from start to finish. I had electric underfloor heating installed in my living room by Rayotec and all I can say is that I am considering having it in other rooms too. James has been incredibly helpful at all times. He explained the process and how everything works. He was very accommodating and flexible with timings as everything happened during summertime and with holidays and all he was able to move things around and set up my underfloor heating almost immediately, for which I am super grateful. The electrician Lewis was a superstar as well, not only did he set up the underfloor heating but he sorted a couple of minor things that were left in a mess from the previous person. In terms of cost, I think considering the excellent quality the price was more than fair and certainly better than having water-based system. Needless to say the room with the underfloor heating is the favourite in the house. Thank you James and everyone at Rayotec for the super efficient and smooth service. For anyone on the fence and thinking your house is too old, it's not, do it, it's the most uniform warm you'll feel in a room, and definitely worth it.
Absolutely amazing company Shaun in the under floor heating department has been a great help as it’s my first time installing underfloor heating as an electrician. As it was my first time I over ordered my underfloor heating without realising it couldn’t be cut to size but the refund process was nice and easy dawn in finance was great processing my refund and made sure it went through without a hitch. I will definitely be using RAYOTEC again not just because of quality of product but because of the team behind it
I bought a 7m2 underfloor heating mat with 10mm insulation and a wi-fi enabled thermostat. Faris, was extremely helpful and amended the original quote as my floor sizes changed due to kitchen cupboard placement. The price was competitive and delivery was free and overnight. Clear instructions are included and Faris sent videos to clarify installation onto a screeded floor. Installation took one day and I screeded over on following day. I had a qualified electrician check installation and connections to mains as specified by warranty, which runs for 30 years. In short (no pun intended) I would recommend Rayotec to anyone and will be buying from them again when I refurb our bathroom
I used an elite cable system in my recent bathroom refurbishment and it was such an easy process. The unexpected bonus was that the thermostat appeared in my Smart Life app (where i controll all my wifi plugs) so I vcan now control the bathroom floor as and when I need it. So impressed was I with the setup that I will now be installing a second system in my shower room refurb. Can't recomend the syetm highly enough
This company was maintaining our solar system, and I’ve updated my review from 1 star to 5 stars based on their excellent customer service. Some of the earlier issues were due to miscommunication from our estate management company, so it was only fair to revise the rating. The team has been very responsive and diligent in addressing our concerns, and they’re now looking into things further. While their maintenance/service/remedial costs are on the high side, Vs other companies the quality of their service and response to the ongoing thread have been good. Mina, in particular, has been outstanding — she took the time to clarify our questions around the work carried out, invoices, and ongoing maintenance etc
Very helpful efficient and professional installation. It was seamless from the start to finish. We are very happy with our underfloor heating, works really well. James went out of his way to help us even after completion with help us setting up and changing our thermostat setting. Highly recommend James.
2016 - Experienced and knowledgeable staff who don't make promises they can't keep. My 4kW solar system is working well and generating the results they said it would. 2024 - Update - I've just used Rayotec for the second time, on this occasion it was to install Electric Underfloor Heating, again I found them very professional, reliable and knowledgeable. More importantly my office is now toasty and warm. Highly Recommended.
NOT A LOT OF INFO IN THE INSTALATION VIDEO FOR FITTING THE TEMPRATURE PROBE DEPTH REQUIRED , PS BISON CONCRETE FLOORS . WHAT WAS THE BOARDIT WAS LAID ON
I bought this with little knowledge of underfloor heating systems. The instructions were simple to understand, the flooring easy to install and leaves a large floor area and room nicely warmed in just a few mins. Would gladly recommend. With the cost of heating it is a little pricey to use regularly, however, worth it for how the floor feels under your feet.
I used the supplied depron sheets under the non self adhesive cable. Great fast service and easy install. Ended up laying a 2mm thick foam underlay around the perimeter of the heating cables to get a more even level before adding the laminate. This was definitely necessary and it would have been nice if this product was suggested at the outset. It could also be supplied as an option. Wireless control is brilliant for a garden room so we can check the room temperature and heat it up before venturing out
Engineer spent 2 minutes with me, said the system was too high to look at and that the whole system needed replacing. He then said “you wont like it “but this 2 minutes will cost you £240!” Absolute rip off!
Follow the signs for Unicorn poo and hens teeth and you will find Rayotec! We recently found this company and we are pleased that we can recommend them to you. The process from start to finish was professional, friendly, informative and all my questions were answered in a way I could fully comprehend and backed up with any data sheets required. A simple floorplan initiated a highly competitive quotation, which was the price we paid. Rayotec helped us with the information required to liaise with the flooring company who would lay the wooden laminate floor on top of the UEH mat. E-mails are answered speedily and with all the information requested. The Rayotec installation teams arrived punctually on the dates agreed. Our home was left clean and tidy once the work was completed. Instructions were given on the day on how to operate the control system and links forwarded afterwards so we had something to refer to should it be needed. The whole Rayotec UEH system works like a dream. UEH is one of the best items we have installed in our recent home refurbishment. We are now going to install UEH in two further rooms and will be using Rayotec every time. They are just a brilliant company. Sadly, I do not have any images of the heating mat, but have included some of the flooring once completed and the control system.
Rayotec underfloor heating- excellent service and good instructions provided for DIY , reliable quality of materials . The free touch screen control was the only exception- fitting this in a 40mm box was very fiddly and the controls are not easy unless you want automatic.
exceptionally disappointing. connectivity failed - thin wires, causing abortive costs. electrician commented that they had seen this before.
I seldom give a top mark. Rayotec were just what we needed. Our solar thermals were shot so we needed a new system. The advice we received was excellent and the installation went well except for a hiccup with a part. Suppliers fault not our installers. All fitted and we look forward to a long relationship with the Company to ensure the panel is well maintained and useful.
We purchased a property with solar panels installed by this company. We contacted them as we had issues with our hot water systems as the property had been vacant for over 6 months. I was told the system in the house heats hot water but is due a service. Having no understanding of the system or solar systems we agreed. I took a days leave engineer arrived and stated ‘I remember this install the gaps to tight in the Eve’s I can’t do the job out weekend guy who’s smaller needs to do it’ 5 minutes on site!!!! Another engineer came a week or so later at £600 charge plus 2 days holiday lost .. Months later I find so paperwork that the system has monitoring equipment. Call rayotech they inform me I have 2 systems and need another call out to fix the monitoring system and check the panels. Engineers turns up 5 minutes informs me a cable between the two battery’s is unplugged and the monitoring system cannot be set up by him and I need to contact Solax the system manufacturer. Another days holiday and a £240 call out. This company takes advantage of people!
Called multiple times and calls are never returned. Customer service advisers all very rude. Avoid at all costs
I needed to get my solar system sorted and Rayotec were so unhelpful it was painful. Emails never answered and call backs promised but never done. Escalated things to the management and Reza came across as very stuck up and refused to help as it was not a rayotec installation. Avoid at all costs
I wanted our 5 year old solar thermal system serviced. Rayotec inspected it for £213 and reported it faulty due incorrect installation. Quote received for £1320 of remedial work. I challenged this but no reply was received. Contacted the original developer /installer and second inspection made. System serviced and topped up, 45 mins work £75.
Please beware with their Solar department as you can end up spending a lot of money for nothing. I am being asked to pay £210 for a 20 minutes inspection although the reason they could not carry out the full service of the solar thermal heater was the model of the heater we had. If the model is this critical to a booked full service, why didn't the person who I booked the service with mention this and asked me to confirm the heater make/model before booking the full service? Also beware that their T&Cs are not at all customer friendly - they are basically all to do with the company making the highest profit at any cost. When I complained, I expected them to deal with it with reason as mine was not a full service nor a call out but instead I was given the same explanation every time and infact they said even if the engineer had left because he could not carry the full service, they would have still asked me to pay £210. So please be extra careful. Their reviews on which may be biased too as the person I spoke felt very confident that my review I have written to which.co.uk will not be published as they will definitely side with the company. Anyways companies like this should be reported and reviewed. Never again will I contact them for anything after such a horrible customer service.
I called Rayotec recently to enquire about help and information regarding an upgrade of our 9 year old solar installation to an "optimised" system. This was my 1st time of speaking to the company Rayotec and I was dealing with a representative called Perry. Perry was friendly, charming, extremely professional and so helpful, quite frankly I was taken back with his knowledge and intention to clarify detailed solutions to all my quite specific questions. What an ambassador of Rayotec! Without doubt I knew this was a company I would chose to work with; and after reviewing their independent feedback I was convinced I needed to look no further for my Solar powered requirements . Thank you Perry, I am sure Rayotec values employees like you which can only enhance their continued business.
no good service and very piracy they have charged me £150.00 for 10 minutes appointment
DO NOT BUY WIFI THERMOSTAT FOR U/F HEATING (not Neo) I purchased three room kits with the wifi thermostats that didnt need a hub connected to the router. The room stats are cheap rubbish, all three would not calibrate to the room real temperature or if they could, there was no way of finding out how from the rubbish instructions, two of them initially connected to the wifi then simply stopped working, one never connected at all. One room was subsequently boiling as the room stat thought it was 14 degrees, another needed to be set to 25 to work at all. Rayotec response - from the guy who wrote the instructions, after multiple emails and calls was 'send them back to get them replaced' with three more that wont work!
Rayotec were incredibly helpful with our queries around their electric underfloor heating and delivery very swift. The Palziv insulation mat unrolls easily and you can cut to size with a Stanley knife. We taped it down to a board base using a combination of double-sided tape and insulation tape at the seams. The heating mat itself is a matter of unrolling and cutting to shape - I recommend a bit of forward planning with this and starting where your electric supply/thermostat control will be. We tested the mat before unrolling, before cutting and after cutting to ensure it was all fine prior to the Quickstep laminate going on top (no insulation between). Within a few minutes of being on you can feel the floor warming up and it gives a comfortable room-wide warmth rather than being blasted out from a single place like a radiator. Am so pleased with the whole system as were the electrician & carpenter who connected it and did the flooring.
BEWARE of the Solar Maintenance department! In trying to avoid the Cowboys I thought to look to Rayotec, a long established Company. HOWEVER the Manager of maintenance is a SHARK! PLEASE make sure you read & fully understand their terms & conditions when you engage them & certainly before they send anybody to your property. Their engineer recharged our system (Supplied & Installed by a Company no longer trading) checked it was operating correctly & sadly on the hottest April day since 1986 mysteriously left the system OFF. That afternoon it reached 128 degrees, heat & pressure then caused a leak on the roof. Scaffolding, 2 roofing engineers & £882 later, a pipe/ joint is the problem & is removed in the hope that it can be replaced. A week later an email arrives stating “I have discussed with Karl his findings and he said that whilst he can get the system running, if required parts were available, but further problems would be likely in the future. The special flexible connectors between the solar panels are special fitting provided by the solar panel maker / installer and we have no means of contacting them”. So now I am left with a missing pipe & no Solar at a Dead End! Yes wait for it ...”Read our terms & conditions”! Would I recommend Rayotec NOT A CHANCE! AVOID! A simple Google search finds a German supplier with a £13 replacement pipe kit …
