Fanastic customer service

Fanastic customer service! We moved into a new building which has Thermosphere radiators installed and has an issue with one of them. The Thermosphere team (Darby Bell) was easy to contact, and expediently arranged for a resolution. It was good to have people to contact and not go through automated bots and bureaucratic processes to get real help.

Top class product with technical & sales team to match

From the first point of contact ( enquiry about the length of flex on their heated towel rails) through the technical information & sales which shaped the decision to purchase their HTR as opposed to a myriad of cheaper competitiors was superb, and always quick & curteous. Rate this company 5 stars for service & product

Fantastic after sales care .

I have had installed in my house 3 underfloor heating mats in the kitchen and 2 bathrooms. I have called ( too many times!! ) to ask for help on programming the thermostat. I have dealt mainly with Ellie . I never write reviews but I am so impressed with her she desrves one! She is super helpful, friendly and has the HUGEST amount of patience which is very rare when dealing with customer services sometimes!! She deals with things very calmly and has a good sense of humour to boot !. I am super impressed with this company , their products are great and the after care 100 %. Thanks Thermoshere

Great support from customer services

At the beginning of 2022 we moved into a newly refurbished house fitted with thermoSphere underfloor heating and Thermostats. We have been really pleased with the air thermoSphere products but in the week before Christmas one of the LED displays in a Thermostat developed a fault. thermoSphere customer services were extremely helpful and the next day a replacement thermostat arrived on my doorstep. I have nothing but praise for the efficiency and helpfulness of this company and their customer services department.

Our builder recommended Thermosphere UFH products for our new kitchen extension build. We bought it from a local tile shop and were very impressed with the performance and product. Not only does the floor heat up really well, but also heats the room. And the thermostats look great.

Our company installed hundreds of electrical underfloor heatings including the Dual Touch Coontroller and heated towel rails by Thermosphere on a high end residental project in central London. The whole supply chain worked very well. Thermosphere support over the construction period was excellent. We had absolutely no claims and can recommend Thermosphere.

Ellie was exceptional - Technically great and easy to talk with

Ellie was exceptional, she was knowledgeable and for the first time in a long time I really felt as though I was talking to an expert, ultimately her technical advice and support regrading towel bars and glass panel heaters led to us making a decision to move away from traditional plumbed heating to electric.

Outstanding service and product

We have used Thermosphere a few times now and Ruben has been absolutely brilliant. It's never too much trouble to amend quotes and answer our queries. The product itself it also the best we have used and makes UFH installations so much easier. It is a pleasure to work with them and would highly recommend.
