Central heating at last!

We have never had central heating in our all electric cottage so when the engineers came we were very excited. The 2 lads were very polite and worked very quickly and cleanly, taking all packaging back with them. However, as my husband and I are 80+ the explanations regarding the app was a bit quick - we are not very tech-minded. However, I got my daughter, who lives in Tenerife sorted us out for the first week, and I now feel more confident using the app.
Your Company was good to work with and we are delighted with the product. Thank you.

Just had 3 heaters fitted , they look great. Richard the fitter arrived on time used dust sheets where he worked. Installed my heaters and took time to show me how to use the controls. The phone app is very user friendly. All good so far.

Do not buy these electric radiators

Do not buy these electric radiators. My mums have never worked properly. Radiator in living room burnt out in a matter of months. One fell off the wall within a week. Cost 3 times more than any other heating systems. The thermostats are battery operated and only last 2 weeks. The people who fitted the radiators were unprofessional and wanted to rush the job because one wanted to go and play golf and the other wanted to watch football. They left all the thermostats in boxes on a chair and didn’t show my 76 year old mother how to operate. When I asked the company to come out to fix everything they tried to charge £150 call out! Which I refused to pay. They look nice but don’t work and cost a fortune in electric. My mum has now died and there is only one radiator in the house working and nothing else is on in the house and it’s costing £400 a month for one radiator.

Sorry to inform you we do not have any record in our company about you nor your claim. Can you please be so kind to contact us or provide us your contact details so we can short out this problem you have? We have requested your details to TrustPilot but it seems you refuse to provide them to us.
Something strange is happening here because even the most powerfull of our radiators working continuously 24/7 will never achive that level of consumption you mention per month.

Please be so kind to contact us in order to help you on this matter.

Don't buy this system if you want remote access and control

I could almost have copied the review posted on 9th January. The radiators and local controllers work fine, but I'm not convinced they are great value for money. The local controllers user interface is archaic and really awkward to use. The company have been helpful, except in relation to the Harmony control app (Android). If you want a system that you can control easily, then you need to look elsewhere. The app continually loses connection to the radiators and the only way to reinstate it is by a really clunky process that requires you to be local to the home. The only response I could get from Climastar UK was that the wifi signal was weak and caused loss of connection. This is either complete tosh, or a tragic flaw in the system. The connection between app and radiator has to be maintained during loss of internet connection. The router and the internet don't have any memory of the connection, it's all held by the radiator and the app. What happens if there is a power outage? I couldn't get any reply out of Climastar Spain when I tried to contact the email address embedded in the app. The previous UK MD who sold us the system is no longer with them I believe. I don't see any evidence that this company or product is going anywhere.

Dear Mr. Hunter, thank you for your review.
As we have explained you, unless some wi-fi boosters are installed in the house the missconnections will continue. In all cases, as you know, the connection between the wall thermostats and the heaters will always continue without you to have the capacity to loose the control of your radiators. It is simply that your wifi signal is not enough to keep a connection between some of your heaters and your home router.

Great marketing but exceedingly poor product

On 23 October 2024 I replaced my 30 year plus storage heaters with Climastar electric radiators and oh how do I regret that day. My home used to be warm & comfortable virtually all day with only the occasional top up heating required. Instead I’ve purchased what in my opinion are very expensive convection heaters where heat just rises, never “warms” the room and as soon as they go off heat dissipates quickly and room is cold. The brochure extols the virtues of the magma stone and displays these amazing 21st century heaters however to me these are very simplistic convection heaters, mounted on a basic unattractive metal bar.

I accept my heating bills are double because I’m still on Economy 7 while I wait for a smart meter but I am using more units trying to heat my home not less. Then there’s the app! I was actually “told off” for changing the programmes! I think anyone coming from storage heaters with very limited settings would need to play around with the programmes to find optimum heating levels. The app is very unstable – sometimes changing a programme seems to set off a period of instability but at other times it’s just random. The heating goes on when it is not programmed to, changes from auto to manual and also changes temperature settings. Whilst on holiday in Rome at Christmas I was shocked to see heaters on when they were not scheduled to be on and also the consumption graph showing heaters had been on all day whilst I was away and not as programmed. This is so unstable I just do not feel safe to use them long term. I will be raising all my concerns with Climastar to resolve these issues.

I ask you to also read Shad Williams review dated 24 Nov 2024 – I agree totally with his comments so beware of great marketing on an exceedingly poor product. Really don’t understand those positive reviews. I’ve just rechecked Trustpilot today and there’s a run of poor reviews that reflect what I am also experiencing.

Dear Mrs. Hensman,
Thank you for your review. At Climastar UK we're committed to improving what we do, and taking on customer feedback in order to provide the best possible customer experience.
Having discussed with our technical department your case and after all the emails we have exchanged so far. We summarise here below our recommendations.

First, please set the programming you need for each room. We recommend you to contact us and we will set the program on line for you as per your instructions.

Please note that your hall heat will go upstairs in all cases and heat will never be retained in the hall.

Once the program is set up. In case you have to override the program, please do not do it on the app, we recommend you to go to the thermostat of the room where you are, change to manual mode and set the new temperature only for that room. You can revert to prog mode after a while.
We have noticed some wi-fi signal problems in your home, if you continuously change settings directly on the app, those changes may not be implemented quick enough and this may frustrate you. By using the wireless thermostat you will avoid all these wi-fi signal problems you have.
Thank you again and we look forward to receiving your contact.

Let down by poor software ( very)…

I have had 5 rads for over a year and whilst Oliver’s tried to sort out the issues the experience continues to be bad.
I don’t think the rads are particularly bad, it’s the app and wireless part which is so unreliable it means I have to turn all 5 on and off manually. ( ones been offline in the spare room for a year And 2 are currently offline) then they sometimes switch on by magic.
I’m sure they are cost effective but when one in a room turns on without warning and is on for days it’s costly.
I can switch one on via the app and it turns on but a minute or so later it goes off again.
I’ve been sent replacement room thermostats which do have better switching but it’s the WiFi programme build which is poor and basically doesn’t work.
If I programme each one individually it either reverts to the factory one or something wildly incorrect.
In conclusion the rads are good and look nice, the supports tried hard but the system isn’t fit for purpose. I’m told it’s only me having these issues but it can’t be. I’m tech savvy and can tell it’s a software issue so many must have the same issue. If they don’t then why not come out and sort the horrible problem.?I’m happy to try over the phone but I know that we both know it’s not going to solve the problem.
I’ve been very patient but enough is enough. I paid a lot of money for the system and it’s a constant stress builder in my life which it shouldn’t be. Either fix it or out wet rads back in.

Dear Mr Mason,
Thank you for your review. At Climastar UK we're committed to improving what we do, and taking on customer feedback in order to provide the best possible customer experience.
Having discussed with our technical department your case, we can see a number of the issues raised by yourself relating to the schedule and changing the operating mode of the heaters were due to user error on the app itself.
Our team have provided instructional videos to show you what mistakes are being made, and how to correctly complete the functions you are asking. When a command is made by the app you need to allow time for the command to be sent to the server and relayed to the heater and thermostat. If a signal does not reach the heater this will either be due to the signal at the mobile device, the signal at the property, or a combination of the two.
Unfortunatelly with your app you cannot use your mobile as a remote control for you heating when internet signal is not good enough.
Please note that you can also operate your heating system from the wireless thermostats you have in each room. They are connected via radio to your radiators and wi-fi signal will not be a problem at all. They are very easy and intuitive to operate.
We sorry for the inconveniences all this situation is causing you.

In any case, you also can call us directly to solve your doubts in the same moment they arise. We will be happy to help you.

This company is a joke

This company is a joke. I’ve had the heating system in for approx. 12 months. Have had three thermostats replaced out of five. Have had two radiators stop working and needing an engineers attention. I am at present without heat in my bathroom. I was told today that a service engineer will call when they are next in my area. They couldn’t care less if temperatures are below freezing on a regular basis or if we are experiencing a national heatwave. I regret having the system put in 100%.

Dear Ann,
Thank you for your review.
At Climastar UK we're committed to improving what we do, and taking on customer feedback in order to provide the best possible customer experience, and I am sorry to hear your dissatisfaction with your system and service. We had solved your initial enquiry regarding the posted thermostatic controller and miscommunication. Unfortunately during the process of sending your new thermostat we detected the reason for that fault in the thermostat, an internal temperature sensor which would not allow your Ensuite heater to activate.
Following a service call from our engineer it appears this could have been solved quicker by issuing out a replacement thermostat on the first place.
The information we had was not complete and did not allow to take a decision for quick repair.
We have made some internal changes in our technical department so this will not be repeat it.

Radiators disconnecting from the app every other day!

The heaters work fine but they should for what they cost. The app however is a different matter! I paid almost £10,000 for 5 radiators and within a month 4 of them had dropped off the app. I rang for assistance as was worried about disconnecting them from the WiFi and having no heating over winter. The young lady I spoke to was polite but not too confident in her advice on how to reload the radiators back onto the app. After trial and error I managed to reload all four, but the day after one had disconnected again! Am I going to have to reconnect them every other day?

Thank you for your reply but the young lady I spoke to advised me to delete and reload the rooms that were showing as offline. I just did what she advised. I have checked the app and another heater is now showing as offline. I waited a few seconds and nothing has changed. How do I refresh the app?

Dear Janet,
thank you for your review.
You do not have to reconnect the heaters to the wifi any time the connection is lost.
Once the wifi signal is poor the heaters may disconnect to the router, but they will re-connect again once the signal is better.
The program you have set in your app is already in the wireless thermostat provided per each room. If you notice that the wifi signal is not good enough and some heaters may appear disconnected please operate them from the thermostats.
Please note that when you open your app, you will find the heaters in the same status that were last time you opened the app. You have to wait some seconds to refresh the status and check whether they are connected or not.

Poor customer service, expensive to install and run but it certainly keeps flat warm.

Great service from salesman but it went downhill after that. Engineers installed heating but didn't set up clock properly ( it was permanently stuck at midday) so heating didn't work. System is horribly complex and technical. It took multiple phone calls to customer services as they didn't want to send out an engineer. We had to fix it ourselves via phone instructions. Heating finally works and gives out good heat. It is unquestionably an effective system if very expensive but the customer service is seriously lacking. The first electricity bill was also alarmingly high, despite assurances that bills would go down. I had this installed in my elderly mother's flat as she is always cold and was hoping to install the same system in my large, listed, draughty farm house. After our experience with Climastar, I will be looking elsewhere. A disappointing experience, especially given the cost of installation.

Dear Amanda,
Thank you for your email. At Climastar UK we're committed to improving what we do, and taking on customer feedback in order to provide the best possible customer experience. The time being stuck at midday can easily be rectified by reseting the thermostat removing the batteries for a moment and reinserting them. And if this is not workking just call us and we will send you a new thermostat.
We have a number of informative videos on our website and Youtube page that you can view your leisure, and as many times as you like that show how each function of the thermostat works.
Our heaters along with our patented TRIAC make them among the most efficient electric heaters on the market, your bill will reflect how you are using the heaters and how long they are on for.
For helpful tips on how to use your heating please feel free to contact us to discuss and we will be more than happy to assist.
Best regards,

Ash a great ambassador for the company

I was visited by Ash today to take me through the options to replace two radiators with Climastar technology. Ash was very knowledgeable about the product he was suggesting and I found him to be professional and personable.
I have told Ash he will have my decision by the end of the week.
However I've been reading the reviews posted on here and some are quite worrying which are giving me second thoughts. I will sleep on it.

Climastar provide great service.

Climastar provided a modern, hi-tech, energy efficient solution to heating our studio flat. We replaced an ancient storage heater with a new radiator from Climastars " Harmony" range. The service provided from consultation through to final installation was efficient, friendly & very professional. The system supplied is very up to date & yet user friendly.

I recently had the heating system…

I recently had the heating system installed by Climastar UK, and overall, I am quite satisfied with the experience. The installation process was smooth, and the new system has significantly improved the heating efficiency in my home, particularly in challenging areas like high-ceiled Georgian rooms. The team was professional and handled the installation well. The product itself seems to be energy-efficient, as I've noticed a reduction in energy usage. However, I encountered a slight issue with the removal of an old water tank, which was not taken away by the engineers. Additionally, I had some trouble with the thermostat and app integration, which took a bit longer to resolve. Despite minor hiccups, the overall service and product quality are commendable, and I would recommend Climastar UK with a four-star rating.

Avoid this company at your peril.
An app.was arranged at quick notice by this company. The day of the visit we had a call from Steve more or less saying as it was only one radiator for a garden room didn't want to bother visiting .We live in Falmouth and upon asking where he was we were told Chacewater which is 10 miles away .
We were quoted a price of at the top of his head £ 1800 which we thought extortionate.
We told him out of our price range .
If any one phones from the office tell them that he loved his cup of tea with sugar and we more or less had to throw him out ( his words) Totally dishonorable and if they employ people like this deserve to go out of business. An idiot wouldn't touch them with a barge pole.

If you are considering Climastar here…

If you are considering Climastar here is an update now we have our radiators for over a year and now the cold weather has returned. Very happy. Would have given 5 stars except for thermostats. Subtle difference between the 2 we have, annoying loss of settings when changing batteries ie date, time and wireless connection. Be excellent if these items could be addressed. I note in the reply it states that an upcoming software update may cure this. Sadly it does not say when or if this update is automatically carried out. Time will tell.

Excellent!

I've waited a good few weeks now, just in case, but we are totally delighted with our Climastar experience. From the initial enquiry, through to quotation and fitting, everything has been really positive - happened exactly when they said it would be and with helpful, professional and friendly staff. We live in a flat with no gas, so have always had storage heating and an immersion for hot water. We went for a full upgrade to replacing all our radiators and the bathroom towel rail with Climastar radiators, and the installation of an electric boiler. We are already seeing huge savings on our energy bill due to the thermostatic controls, the heat is perfect, the ambient temperature is lovely rather than full on or too cold as we used to experience with the storage heaters. And who knew you could get an electric boiler? Truly life-changing as we now have a high pressure, HOT supply at all times. It also blows my mind that there are no ongoing maintenance costs. Yes, it was expensive, but the space we have gained with smaller radiators, and the removal of our water and immersion tanks, the aesthetic and the convenience is well worth it.

APPALLING!

For the love of Jehovah - DO NOT USE THIS COMPANY!!
My father in law needed a new boiler and contacted this firm. One of their engineers arrived the next day and recommended an electric one. The sales pitch was somewhat aggressive and forceful. My father in law is 89 and felt extremely intimidated.
The engineer that came round was overly expressive with his hands as he conducted his forceful sales tactics which led to the family dog jumping at him as he perceived him as a threat. The engineer then SLAPPED milo across the face. I have never been more appalled and shocked in all my life! My wife was in the kitchen at the time, came into the living room and told the man to leave and never bloody come back! Do not use this company!!!
