ThermoSphere Avis 

Recently installed Thermosphere membrane electric underfloor with BT21 thermostats controlling the various areas. Really happy with the finished result and love the fact I can control them from my phone. Spot on!

A Thermosphere Dual Control was installed in my shower room to control the underfloor heating and towel rail in May last year. I have found that whenever there is a power cut (even for only 2 minutes) the heating does not come back on when power returns. The controller switches off and has to be manually switched on again. I see that as a very significant deficiency in the product. I contacted Customer Service in February who told me that there was nothing that could be done to change this, but newer Dual Controls came on after power outages. So they do they do recognise this as an issue. Not happy.

Absolutely first class products, service and technical support... faultless!

Would just like to thank Lirona from your customer service team, for over 2 years now she has helped me and my company win and secure jobs and with the technical backup support she offers you cant go wrong with these products, great company and great support, also thanks to jodie as well

Fantastic products, very easy to install! Plus the team were great when I had a question about what to order, knew what I was asking and came up with a quick option that solved the problem with two floors I needed UFH for.

Ellie was extremely helpful in providing me with some clarification on the user instructions that had been provided at the time of purchase. She also kindly sent me updated instructions for my information.

Ellie Lisbon was extremely helpful this morning. We have recently had a bathroom renovation with underfloor heating fitted and have struggled to set timings for the Eco setting. Seems to come on randomly. She has identified the problem and we now need the electrician back. So far to date she’s been extremely helpful, very pleasant and communication superb. Thanks Ellie

Ellie Lisbon was very helpful in guiding me through setting up the company's Dual Control Underfloor Heating Controller and I am very grateful for both her patience and her product knowledge.

The only reason this is not a 5 star review is that Ellie wouldn't have had to help me in the first place if the Instruction Book that came with the product hadn't been so inadequate!

Great advice and co-operation from Ellie in my attempts to set up a new underfloor heating system. So refreshing to deal with somebody who genuinely wants to help a customer. She knows her stuff as well!!
Cheers Ellie, you come highly recommended!

All the best

I can’t thank Jodie from Customer Support enough.
My elderly mother recently moved and we could not work out how to use the heating thermostat. I called Customer Support and Jodie spent time walking me through how to set up and use the thermostat properly. Jodie even sent me pictures!
The following day Jodie even took the time to call me to make sure that I had managed to get the heating working. Such amazing care and customer service! Thanks to all of Jodie’s help Mum is now warm.
A big thank you Jodie.

I've just had wonderful customer service from Linora Mehmeti at Thermosphere. I'd been completely defeated with an error message and the inability to solve it, or programme the timer. Linora was so lovely,patient and calm and took me through every single day to set each timer correctly and even when I managed ( somehow) to do a factory reset in error, she still kept going and helping me. A second call to her sorted another smaller issue and she was still laughing and smiling ( possibly grimacing and I wouldn't blame her if she had been!) . Really has made the use of this much simpler as I now know if I run into trouble again, there is an immediate response to a call from a human being ready to help. Thank you again Linora. You were marvellous!

Having sold many different brands of UFH, I came across ThermoSphere via a customer lead. After the first order went to plan, I decided to try them with another order... they are now my go to Electric UFH supplier. Excellent communication, prompt delivery.. even directly to my customers' front door. Keep it up.. Thank you!

We've had a Comfortzone (the old name for ThermoSphere) thermostat for our underfloor heating for about 8 years. It's developed a fault recently (not controlling the temperature properly). I rang ThermoSphere customer support - spoke with Rhylan - and they were excellent. I wasn't sure they'd have support for homeowners, rather than just people in the trade, but they were happy to help. We talked through the problem and they were able to diagnose the fault. Not something it's possible to fix, but the service was very good. Will happily buy another Thermosphere product for that reason.

We have been dealing with this company many years and have always found it a pleasure. the sales team are very knowledgeable, helpful and the tech team are amazing. I have personally been looked after by ruben and have always found he is always professional and always has a solution. Great company with amazing staff!!

We have had so many problems setting up now the up arrow dosent work so we can't use it as it stuck to low temperature we have only used it two times not happy

Super helpful and knowledgeable team. Top quality products - very happy and will recommend to my friends

Excellent customer service from Jodie Swain today who helped reset a Thermonet thermostat for a guest bathroom which has been used very little since Covid.
Very courteous and patient at taking me through updating the settings.

Great service from the rep who answers any questions that we have in a friendly manner.
The installers love this product as the cable and membrane are very easy to work with.
Would certainly have in my home.

We regularly place orders with ThermoSphere and always find the service we receive very good.
Thank you ThermoSphere

Our bathroom fitters fitted thermo sphere 5245RF a few months ago and I have been battling with trying to programme it ever since (with little progress). I am sorry to say that this is the most counter intuitive programming device I have come across. The first issue is that the touch screen is not particularly sensitive and needs a firm poke with my finger several times before it responds. On screen there are many icons that are confusing and do not necessarily represent clearly their intended function. As far as scheduling settings, well life is too short to set each day individually without the function to repeat daily patterns. Disappointed with this product and would expect better for a high end control.
